inventories and reliable suppliers needed to maintain or rebuild critical infrastructure at home.
Finding the natural resources of the United States “deficient or insufficiently developed” to
supply domestic raw material demand “in times of national emergency,” Congress since 1939 has
authorized the U.S. Government to stockpile “strategic and critical materials” and to develop
domestic sources of their supply.
Currently managed by the Department of Defense (DOD), this
National Defense Stockpile (NDS) may be used to provide
domestic manufacturers with emergency access to essential production inputs “to serve the interest of national defense only.”
These materials typically include nonfuel mineral commodities purchased from domestic or foreign sources prior to the onset
of a national emergency through government contracts. The U.S. Government stockpiles these materials to meet the
estimated needs of the United States for national defense in the event of particular national emergency scenarios (such as, for
example, large-scale conventional war with China) for a specified duration (established by Congress in law).
As of March 2023, the National Defense Stockpile contains $1.3 billion in total assets, including $912.3 million of stockpiled
material. As of April 2023, current NDS inventory mitigates less than half of estimated strategic and critical materials
shortfalls for military requirements; less than 10% of essential civilian demand shortfalls; and approximately 6% of total net
shortfalls in “base case” national emergency scenarios. The vast majority of the $13.5 billion gap between current stockpile
assets and current stockpile requirements would support nondefense critical infrastructure demand in the event of an attack on
the United States.
While NDS acquisitions and operating costs are typically self-funded by revenue from stockpile sales rather than
congressional appropriations, since FY2022 both Congress and the executive branch have expressed renewed interest in
appropriating funds for new NDS acquisitions and modifying aspects of stockpile management.
In addition to providing background on the NDS, this report analyzes selected issues that Congress may face related to NDS
management, including:
• Assessing NDS funding tradeoffs;
• Determining which national emergency scenarios should be used to generate NDS requirements;
• Assessing market impacts of rapid stockpile acquisition strategies;
• Adapting stockpiles to anticipate and incorporate technological innovation;
• Private sector stockpiles of strategic and critical materials;
• Nondisclosure agreements with industry for robust NDS planning; and
• Addressing material weaknesses in NDS financial audits
According to the White House, “Nearly every agency of the U.S. Government has a unique capability that can be brought to
bear to increase the sustainability of strategic and critical materials supply chains.” Since 1939, the NDS has provided a
method of mitigating strategic and critical materials supply chain risk, deterring aggression, and facilitating whole-of-
government emergency preparedness.

Emergency Access to Strategic and Critical Materials: The National Defense Stockpile
Introduction
For more than a century, national security policymakers have approached physical stockpiling of
industrial raw materials as one policy option for mitigating national defense supply chain risks,
deterring aggression, and anticipating “actions or events outside the control of the Government of
the United States.”1 Finding the natural resources of the United States “deficient or insufficiently
developed to supply the military, industrial, and essential civilian needs of the United States for
national defense,” Congress since 1939 has utilized the Strategic and Critical Materials Stock
Piling Act (50 U.S.C. §98,
et. seq., as amended) to develop and oversee a national stockpile of
certain “strategic and critical materials.”
This report provides background on this
National Defense Stockpile (NDS) and analyzes
selected issues that Congress may face related to its management, including:
• Assessing NDS funding tradeoffs
• Determining which national emergency scenarios should be used to generate
NDS requirements
• Assessing market impacts of rapid stockpile acquisition strategies
• Adapting stockpiles to anticipate and incorporate technological innovation
• Private sector stockpiles of strategic and critical materials
• Nondisclosure agreements with industry for robust NDS planning
• Addressing material weaknesses in NDS financial audits
The NDS’s statutory purpose is:
to provide for the acquisition and retention of stocks of certain strategic and critical
materials and to encourage the conservation and development of sources of such materials
within the United States and thereby to decrease and to preclude, when possible, a
dangerous and costly dependence by the United States upon foreign sources or a single
point of failure for supplies of such materials in times of national emergency.2
The Department of Defense (DOD) manages the NDS and has delegated authority as the National
Defense Stockpile Manager to release stockpiled materials to eligible domestic manufacturers in
the defense industrial base and other critical infrastructure sectors under certain conditions.3

Emergency Access to Strategic and Critical Materials: The National Defense Stockpile
Defining “Strategic and Critical Materials”
50 U.S.C. §98h-3 provides an overarching definition of strategic and critical materials. They are
“materials that (a) would be needed to supply the military, industrial, and essential civilian needs
of the United States during a national emergency, and (b) are not found or produced in the United
States in sufficient quantities to meet such need.” (See
Appendix B for a list of these materials.)
50 U.S.C. §98b gives the President authority to determine which materials are strategic and
critical.4 Since 1939, various agencies have used delegated authority and interagency
coordination to make definitive lists of strategic and critical materials.5 Currently, the Department
of Energy (DOE) makes a definitive list of “critical materials”; the Department of the Interior’s
(DOI’s) U.S. Geological Survey (USGS) makes a definitive list of “critical minerals” (a subset of
critical materials); and the Defense Logistics Agency, utilizing delegated Secretary of Defense
authority, incorporates these lists into its own assessment of National Defense Stockpile
requirements, generating a definitive list of strategic and critical materials for purposes of the
Stock Piling Act.6
Defining “National Emergency”
50 U.S.C. §98f authorizes the President to release stockpiled materials “in time of war declared
by Congress or during a national emergency.”7 50 U.S.C. §98h-3 defines a national emergency as
“a general declaration of emergency with respect to the national defense made by the President or
by the Congress.” Throughout the stockpile’s history, several proclamations, executive orders,
materials; see E.O. 14051, “Designation to Exercise Authority over the National Defense Stockpile,” 86
Federal
Register 60747, October 31, 2021. Stockpiled materials may also be loaned to the Department of Energy or military
departments under 50 U.S.C. §98e(f) or bartered under conditions established by 50 U.S.C. §98e(c). U.S. policy
currently designates 16 critical infrastructure sectors, including the defense industrial base sector. “Essential civilian
needs” during a national emergency may include functionality of the other 15 critical infrastructure sectors, including
the critical manufacturing sector.
4 Functions of the President under 50 U.S.C. §98b were delegated to the Secretary of Defense by section 1 of E.O.
12626, “National Defense Stockpile Manager,” February 25, 1988, 53
Federal Register 6114.
5 In addition to the phrase “strategic and critical materials,” the act also refers to “materials critical to national
security,” tasking the Strategic and Critical Materials Board of Directors with recommending to the Secretary of
Defense a strategy for ensuring a secure supply of these materials. See 50 U.S.C. §98h-1.
6 See U.S. Department of Energy,
Critical Materials Assessment, July 2023, p. 1. DOE funds critical materials research
and development to mitigate supply chain vulnerabilities using authorities derived elsewhere than the Strategic and
Critical Materials Stock Piling Act, such as the Energy Act of 2020, which was passed as Division Z of the
Consolidated Appropriations Act, 2021 (P.L. 116-260). For snapshots of interagency strategic and critical materials
supply chain resilience challenges, see The White House,
Building Resilient Supply Chains, Revitalizing American
Manufacturing, and Fostering Broad-Based Growth: 100-Day Reviews under Executive Order 14017, June 2021.
7 50 U.S.C. §98f (b) states that any order to release stockpiled materials under this subsection “shall be promptly
reported” in writing to the House and Senate Armed Services Committees. While the Strategic and Critical Materials
Stock Piling Act was initially enacted to mitigate supply disruptions associated with wartime industrial mobilization
and sustained wartime production demands, 50 U.S.C. §98f as currently written provides the President (and USD
(A&S)) with some discretion to release stockpiled materials outside of explicit war or national emergency situations. 50
U.S.C. §98f (a)(1) and (a)(3) allow for release of stockpiled materials whenever the President, or USD(A&S) as
presidential designee, determines the release of such materials is required “for purposes of the national defense.” These
authorities in conjunction with authorities to dispose of excess stockpiled materials have governed stockpile releases in
peacetime conditions. Historically, some analysts have claimed that instances of stockpile material release and disposal
nominally aligned to “national defense purposes” have overlapped with “economic or budgetary purposes” currently
prohibited by 50 U.S.C. §98a(c). This ambiguity was particularly salient in the decades following WWII, when the
NDS represented perhaps “the largest body of marketable commodities under the control of one market actor in the
world.” See Patricia Elaine Perkins, “The United States strategic stockpile and price determination in international
metals markets” (Ph.D. diss., University of Toronto, 1989), p. 1.

Emergency Access to Strategic and Critical Materials: The National Defense Stockpile
joint resolutions and treaties respecting war, neutrality, and peace have declared (or terminated)
states of war or national emergencies, affecting national stockpile strategy.8
A network of laws and administrative policy situates NDS management within whole-of-
government approaches to “national security emergency preparedness” and critical infrastructure
protection.9 U.S. policy currently designates 16 critical infrastructure sectors, including the
defense industrial base (DIB); critical manufacturing; and nuclear reactors, materials, and waste.
The Stock Piling Act requires the President to prioritize stockpile allocations toward “military,
industrial, and essential civilian needs” in a national emergency, which may entail allocating
stockpiles to ensure functionality of critical infrastructure sectors.10
The Stock Piling Act itself does not provide details about the administrative and contractual
mechanisms used to allocate stockpiled materials under a declared war or national emergency.
These mechanisms are set forth in other locations in the
U.S. Code or Code of Federal
Regulations (CFR) and are implemented by allocation policies established by executive branch
policy guidance, individual agency procedures, emergency acquisition, and contingency
contracting.11
8 Months after Congress signed the Stock Piling Act in June 1939, for example, President Franklin D. Roosevelt
proclaimed a national emergency to enforce U.S. neutrality in WWII and strengthen national defenses “within the
limits of peacetime authorizations.” See Proc. No. 2352, Sept. 8, 1939, 4 F.R. 3851, 54 Stat. 2643. President Roosevelt
then proclaimed “an unlimited national emergency” on May 27, 1941; see Proc. No. 2487, May 27, 1941, 6 F.R. 2617,
55 Stat. 1647. For information on post-Vietnam national emergency declarations, see the National Emergencies Act (50

by the Director of the Office of Emergency Planning, but “must be supplemented by allocation directives issued by the
Departments responsible for control of the particular resource” in the contemporary federal emergency preparedness
framework. These allocation orders would typically be terse statements signed by the department head listing the

Emergency Access to Strategic and Critical Materials: The National Defense Stockpile
Strategic Context
Strategic stockpiling reflects and responds to a basic tension in U.S. public policy. On one hand,
“Congress finds that the security of the United States is dependent on the ability of the domestic
industrial base to supply materials and services for the national defense and to prepare for and
respond to military conflicts, natural or man-caused disaster, or acts of terrorism within the
United States;” on the other, “Congress finds that the natural resources of the United States in
certain strategic and critical materials are deficient or insufficiently developed to supply the
military, industrial, and essential civilian needs of the United States for national defense.”12
Since passage of the Strategic and Critical Materials Stock Piling Act in 1939, executive branch
officials have wielded increasingly sophisticated analytical tools for assessing national defense
requirements. Using economic modeling, cost estimates, intelligence forecasts, and regularly
revised combat scenarios, these analytic assessments reflect current strategic threat perceptions
and in turn drive DOD’s annual budget requests.13
During testimony before the House Armed Services Committee on March 29, 2023, the then-
Chairman of the Joint Chiefs of Staff General Mark Milley stated, “If there was a war on the
Korean peninsula or great power war between the United States and Russia or the United States
and China, the consumption rates [of conventional munitions such as rockets and guided missiles]
would be off the charts.”14 The Chairman added that DOD has reassessed the quantity of
munitions it would likely expend during such a war, adding: “[I]t’s those estimates that then form
the basis of the munitions request in the budget.” He concluded by saying: “We’ve got a ways to
go to make sure our stockpiles are prepared for the real contingencies.”15
The Chairman’s remarks emphasize War Reserve Materiel but may implicate the NDS.16 If the
United States entered a large-scale conventional war (or armed conflict national emergency) with
quantity and material needed by a given industrial sector under that department’s emergency control, along with a
statement about which national stockpile should be drawn from (e.g., the NDS). The stockpile operations manager (in
1965, the General Services Administration, but today the Defense Logistics Agency) would then “arrange outshipments
from depots it selects” to deliver the industrial raw materials to the nearest qualified domestic manufacturers
“regardless of regional boundaries.” See Executive Office of the President,
Stockpile Report to the Congress: July –
December 1965, April 1966, Annex 1. In March 2012, President Barack Obama authorized DOD under national
emergency conditions to invoke Defense Production Act (DPA) Title I authorities to “control the general distribution of
any material…in the civilian market” with respect to “stockpiles managed by the Department of Defense.” See E.O.
13603, “National Defense Resources Preparedness,” March 16, 2012, 77
Federal Register 16651, Sections 101, 201,
202(a), 303(b), 306, 801(j) and 801(m). Note that 50 U.S.C. §4516 also designates “energy” as a strategic and critical
material under these conditions. See 50 U.S.C. Chapter 55 (the Defense Production Act). In an emergency, DPA Title I
authorities could be utilized for acquiring stockpiles of strategic and critical materials. For consideration of additional
DPA authorities to expand industrial capacity related to strategic and critical materials, see CRS Report R47124,

13 U.S. officials have since the 1770s undertaken to stockpile essential materials based on estimated national defense
requirements. The Second Continental Congress formed a secret committee in 1775 to establish clandestine supply
chains with neutral countries in the War of Independence, purchasing gunpowder stockpiles in secret from Spain (and
through the Dutch Caribbean free port of St. Eustatia) while gathering intelligence needed to seize British ammunition
stockpiles. See Central Intelligence Agency,

Emergency Access to Strategic and Critical Materials: The National Defense Stockpile
a major naval power, supply-and-demand networks for industrial raw materials could be
disrupted, affecting critical infrastructure sectors including the defense industrial base.17 Export
controls or boycotts implemented by an adversary country or other economic actors might
constrain U.S. Government and domestic industry access to certain raw materials markets. It
might become difficult for government agencies and domestic industries to trade with some
countries, or obtain industrial raw materials from certain foreign locations through ocean, air, rail,
or ground transportation. An adversary might attack, attempt to blockade, or facilitate sabotage
along trade routes at critical chokepoints, directly or through proxies.18
In the early stages of conflict, armed forces would generally be reliant on redistribution of current
equipment stocks, transportation of War Reserve Materiel under contested logistics, accelerated
depot-level maintenance output, diverted security assistance production, and purchase of dual-
use, commercial-off-the-shelf products.19 In a prolonged conflict depleting reserve inventories of
key weapon systems, munitions, and combat support equipment, DOD might leverage its global
defense posture of forces, facilities, and international agreements but might also, under certain
conditions, face constraints that jeopardize the achievement of operational and strategic
objectives.20
In prolonged conventional armed conflict scenarios, the risk to national security arising from
inadequate domestic raw material inventories depends to a great degree on assumptions about
successful homeland defense; weapon and munition usage rates; equipment losses; control of sea
lanes of trade; air superiority; enduring access to key foreign suppliers; durability of international
agreements and domestic critical infrastructure; private sector emergency stockpiling initiatives;
and the efficacy of the domestic industrial base in surging production or transitioning to full or
total mobilization of the armed forces and national economy.21
“Realistic Stockpiling” for Great Power Conflict
In meeting the actual needs of “real contingencies” related to large-scale armed conflict, the
National Defense Stockpile has been seen as inadequately stocked at the moment conflict arose,
as former President Dwight Eisenhower reflected in 1963:
You will recall that, when we became involved in World War II, our lack of an adequate
stockpile of strategic and critical materials gravely impeded our military operations. We
were therefore forced into costly and disruptive expansion programs. The nation was
compelled to divert, at a most critical time, scarce equipment and machinery and manpower
to obtain the necessary materials.... But even after this experience we had not fully learned
our lesson.… After we became involved in hostilities in Korea, we went through
experiences almost identical with those of World War II—only then did realistic
stockpiling begin.

Emergency Access to Strategic and Critical Materials: The National Defense Stockpile
During WWII, the Metals Reserve Company (MRC), a subsidiary of the government-owned
Reconstruction Finance Corporation, spent $2.75 billion (approximately $42.9 billion in FY2024
constant dollars) on the direct purchase of 50 “strategic and critical metals and minerals” from
“51 countries, 39 states, and the Philippines” to meet the immediate requirements of wartime
production in the domestic industrial base.23 The United States used MRC for procurement of
strategic and critical materials in lieu of NDS inventories for those requirements. The NDS was
used as a “last ditch” supply of strategic and critical materials during WWII, due in large part to
its inadequate size upon formal declaration of war.24 The first stockpile report to Congress,
covering the period from June 7, 1939, to December 31, 1946, states: “Had that Act [i.e., the
Stock Piling Act passed June 7, 1939] been passed in the early 1930s, and adequately
implemented by appropriations, most if not all of the highly expensive procurement activity
which took place during the war could have been obviated.”25
Post-Cold War vs. Post-post-Cold War Stockpile Strategy
Compared to high-intensity, long-duration great power armed conflicts, post-Cold War and
counterinsurgency-centered armed conflict scenarios have tended to imply less supply chain
risk.26 In the post-Cold War era, stockpile planners incorporating assumptions from the National
Military Strategy reportedly assumed a seven- to nine-year period of “early strategic warning,”
during which time emerging strategic threats could be identified and stockpiles of strategic and
critical materials acquired to prepare for and deter large-scale armed conflict.27 Stockpiles
accumulated since the Korean War were largely liquidated as part of a post-Cold War “peace
Materials: U.S. Alternatives (Washington, D.C.: National Defense University, 1990), p. 300. A 1964 stockpile report to
Congress notes that in 1963 the U.S. Government began modeling the strategic and critical materials needs of all
“major segments of the economy” following a nuclear war, to include “requirements not only for survival but also for
rehabilitation and reconstruction of new facilities as needed.” Stockpile requirements planning thus considered both

26 DOD policy currently defines “supply chain risk” as:
The risk of intentional or unintentional disruptions to the flow of product, materiel, information, and finances
across the lifecycle of a weapon or support system which negatively impact the integrity of DoD logistics
infrastructure; materiel acquisition and supply (including critical suppliers and critical components); key
transportation modes and routes; and storage and stockpile activities. Disruptions could arise in any sub-set of
the DoD supply chain, such as cybersecurity, software assurance, obsolescence, counterfeit parts, foreign
ownership of sub-tier vendors, climate change-related risks, and other categories of risk that affect the supply
chain. The risk that an adversary may sabotage, maliciously introduce unwanted function, or otherwise subvert
the design, integrity, manufacturing, production, distribution, installation, operation, or maintenance of a system
so as to surveil, deny, disrupt, or otherwise degrade the function, use, or operation of such system.

dividend” reflecting broad access to foreign sources of supply under contemporary combat
scenarios.28
For decades, “realistic stockpiling,” to use President Eisenhower’s phrase, led to disposal [sale] of
stockpiled materials no longer estimated to be in material shortfall under anticipated emergency
conditions. According to DOD, “Beginning with the early 1990s, the Department of Defense
determined that over 99% of the [NDS] inventory was excess to the Department’s needs and
Congress authorized its disposal.”29 Today, DOD reports $1.3 billion in total NDS assets—
comparable to pre-WWII levels—including $912.3 million in material inventories.30
The October 2022 National Security Strategy announces that “the post-Cold War era is
definitively over and a competition is underway between the major powers to shape what comes
next.”31 After 20 years of counterinsurgency focus, recent national strategy documents and DOD
budgets reflect great power armed conflict scenarios and strategic threat perceptions.32
January 1, 2035: Statement of Policy
Section 848 of the William M. (Mac) Thornberry National Defense Authorization Act for Fiscal
Year 2021 (P.L. 116-283) directs the Secretary of Defense to utilize the National Defense
Stockpile, among other tools, to ensure “access to secure sources of supply for strategic and
critical materials” that “fully meet the demands of the defense industrial base” and “eliminate the
dependence of the United States on potentially vulnerable sources of supply” not later than
January 1, 2035.33 These policy aims involve the U.S. military’s full global defense posture and
imply prolonged whole-of-government coordination across military, informational, diplomatic,
financial, intelligence, economic, legal, and developmental (MIDFIELD) instruments of national
power.34 Their achievement may depend on efforts beyond DOD’s control, including
congressional appropriations over the coming decade.

Emergency Access to Strategic and Critical Materials: The National Defense Stockpile
Current Stockpile Requirements
Currently, DOD selects strategic and critical materials for inclusion in the National Defense
Stockpile that are expected to be in “material shortfall” in a national emergency scenario
“consisting of a military conflict combined with an attack on the Homeland.”35 This “base case”
scenario lasts a total of four years, the first year of which involves active combat followed by
three subsequent years of post-conflict industrial recovery and replenishment.36 Shortall materials
generally include nonfuel mineral commodities like cobalt and tin, along with semi-processed or
processed materials such as TNT and high-purity carbon fiber that function as common
production inputs for national defense applications.37 While details of some shortfalls are
classified, a 2023 unclassified NDS inventory list is provided i
n Appendix B.38
DOD’s Defense Logistics Agency (DLA) reportedly monitored 283 candidate materials for its
2021 and 2023 stockpile assessments, with 148 incorporated into formal NDS planning models.39
Results of 2021 Stockpile Requirements Assessment
In the 2021 stockpile requirements assessment, 53 materials were determined to be in shortfall
and therefore “strategic and critical” in a congressionally mandated, classified armed conflict
scenario involving China.40 Of these 53 materials, according to the assessment, 37 have supply
chains controlled by a “foreign market dominator” (i.e., more than half of global production
occurs in a single foreign country). Twenty-nine of 53 materials have one domestic provider
qualified to meet military or essential civilian requirements (as of June 2021), according to the
assessment, and an additional 18 materials “have no domestic production at all.”41 According to a
review of strategic and critical materials supply chains published by The White House in June
2021, U.S. import dependence for these 53 materials extends to 84 countries:
• 27 countries each produce exactly 1 shortfall material;
• 20 countries each produce 2 shortfall materials;
• 16 countries each produce between 3 and 5 shortfall materials;
• 11 countries each produce between 6 and 10 shortfall materials;
• 7 countries each produce between 11 and 20 shortfall materials;
• and 3 countries each produce more than 20 shortfall materials.42

Emergency Access to Strategic and Critical Materials: The National Defense Stockpile
The People’s Republic of China (China, or PRC) is the primary global producer and/or primary
U.S. supplier of 20 or more shortfall materials.43 This is potentially significant in part because the
“base case” armed conflict scenario grounding current stockpile requirements involves a
conventional armed conflict with China.44
Results of 2023 Stockpile Requirements Assessment
The FY2023 stockpile assessment discovered net shortfalls in 88 materials valued at $14.83
billion.45 Of this total, $12.21 billion worth of shortfalls would cover essential civilian demand for
24 materials and $2.41 billion would cover military requirements associated with 69 materials.46
Given March 2023 reported stockpile inventories of $912.3 million, the FY2023 stockpile
assessment suggests current NDS inventories cover 37.9% of projected military shortfalls, 7.5%
of essential civilian demand shortfalls, and 6.2% of total net shortfalls in base case national
emergency scenarios.47 As of April 2023, the gap between total NDS assets ($1.3 billion) and
total net shortfalls is $13.5 billion.48
Congressional NDS Appropriations
Congress appropriated a total of $218.5 million for new NDS acquisitions in FY2022 and
FY2023.49 Since 1969, however, NDS acquisitions have typically been funded with revenue
generated from sales of excess inventory in the stockpile.
From the inception of the stockpile in 1939 through 1969, Congress appropriated over $94 billion
in constant FY2024 dollars for the acquisition, storage, maintenance, and upgrade of strategic and
critical materials in the National Defense Stockpile.
Table 1 lists congressional appropriations for
the stockpile prior to establishment of the NDS Transaction Fund in 1979, which Congress
established to allow revenues from stockpile disposals to fund the acquisition of new materials
and other necessary NDS expenses.50

Emergency Access to Strategic and Critical Materials: The National Defense Stockpile
Notes: Real dol ar values are net amounts reported in stockpile reports to Congress, excluding administrative
transfers of budget authority to non-NDS accounts during a given fiscal year and excluding multi-year contracting
authority in advance of appropriations, as authorized in the respective Public Law and reported in subsequent
Stockpile Reports to Congress. Values in the “Appropriated Amounts (current dol ars)” column therefore may
not match appropriated amounts listed in the respective Public Law. Cases where two entries cover the same
Public Law represent appropriations for new stockpile activities along with appropriations to reimburse stockpile
accounts for obligations incurred pursuant to advance contracting authority (in lieu of appropriations) provided
in prior Public Laws.
Since 2022, Congress has expressed renewed interest in providing budget authority for new
stockpile acquisitions, in part because DOD has expressed concern that annual stockpile
operations cannot be sustained in the long term with current NDS assets.51
NDS Organizational Structure52
This section surveys key features of stockpile strategic planning, management, acquisition and
disposal, resource management, research and development, and congressional reporting under 50
U.S.C. Chapter 5, Subchapter III: Acquisition and Development of Strategic Raw Materials.
Strategic and Critical Materials Board of Directors53
Section 1411(b) of the James M. Inhofe National Defense Authorization Act for Fiscal Year 2023,
(P.L. 117-263) established a board of directors to develop and assess NDS strategic plans and
operations. The board must at minimum include 13 members:
• The Assistant Secretary of Defense for Industrial Base Policy is the chair
• Four additional members are chosen by the chair of the board, with relevant
expertise (e.g., one member each specialized in “military affairs, defense
procurement, production of strategic and critical materials, and finance”)54
• Four members total designated by each of the Secretaries of Commerce, State,
Energy, and the Interior
• Four members total designated by House and Senate Armed Services Committees
(i.e., the Chairman and Ranking Member of the Readiness Subcommittee in each
chamber choose one board member each)
Congress has tasked this board with developing stockpile strategy for submission to the Secretary
of Defense; approving an annual budget plan; reviewing planned stockpile acquisitions or sales
against “projected domestic and foreign economic effects;” and establishing performance metrics
for evaluating whether the National Defense Stockpile Manager is adequately implementing
stockpile strategy.55

Emergency Access to Strategic and Critical Materials: The National Defense Stockpile
National Defense Stockpile Manager
P.L. 100-180 Division C, Title II, the “National Defense Stockpile Amendments of 1987”
amended the Stock Piling Act, requiring the President to designate “a single Federal office to
perform the functions of the President under this Act.”56 To implement the requirement, President
Ronald Reagan issued Executive Order 12626 designating the Secretary of Defense to perform
this role of “National Defense Stockpile Manager.”57 The executive order also authorized the
Secretary to delegate responsibilities under the act as needed to perform these functions.
The Stockpile Manager has a variety of responsibilities under the act, including:
• Use appropriated funds to acquire shortfall materials, even doing so without
explicit authorization in law under certain circumstances.58
• Receive advice from the Strategic and Critical Materials Board of Directors.59
• Submit financial statements and an Annual Materials and Operations Plan to the
Board of Directors.60
• Submit an annual report to the congressional defense committees on foreign and
domestic stockpile purchases, disposals, barter transactions, research and
development efforts, and planned expenditures over the next five years.61
Within DOD, the Secretary delegates these functions to the Under Secretary of Defense for
Acquisition and Sustainment (USD(A&S)), who further delegates responsibilities to the Director
of the Defense Logistics Agency (DLA), the nation’s combat logistics support agency.62 DLA
manages day-to-day NDS operations with oversight from the Strategic and Critical Materials
Board of Directors.
Day-to-Day NDS Operations and Material Assessment: DLA-SM
To consolidate NDS operational activities under one entity, DOD has delegated day-to-day
stockpile management responsibilities specifically to the Defense Logistics Agency’s Strategic
Materials field activity (DLA-SM). DLA-SM maintains the specialized facilities, personnel,
equipment and software required to execute NDS material acquisition, storage, management,

disposal, and recovery activities. It also assesses stockpile composition and quality and provides
NDS contract oversight and resource management.63
The field activity reports NDS inventories at six locations in Indiana, Ohio, West Virginia, New
York, and Arizona.64 For a list of NDS materials at these facilities as of the end of FY2022, see
Appendix B. In FY2022, DLA-SM reported employing 72 civilian personnel, led by an
Administrator and Deputy Administrator headquartered at Fort Belvoir, Virginia and organized
into two directorates: one for strategic planning and market research, and a second for materiel
management.65
As the National Defense Stockpile Manager, DLA-SM tasks include:
• Purchase strategic and critical materials of domestic origin (and prioritize
purchases from the national technology and industrial base above other foreign
sources if not available domestically).66
• Contract with domestic facilities to process and refine stockpile materials.
• Qualify domestic facilities to receive NDS materials under a declared national
emergency and fulfill specific military and essential civilian requirements.
• Contract with domestic facilities to recycle strategic and critical materials.67
Recovering Strategic and Critical Materials from Recycling Operations
Section 1411 of the National Defense Authorization Act for Fiscal Year 2014 (P.L. 113-66)
requires the Stockpile Manager to recover strategic and critical minerals from “excess materials
made available for recovery purposes by other Federal agencies.” Recycling programs are now an
increasingly important DLA-SM contracting activity and an area of significant innovation. The
most recent FY2022 stockpile report to Congress details some of these initiatives under the
Strategic Materials Recovery and Reuse Program (SMRRP).
In FY2022, germanium recovery from military branch “end-of-life scrap” turned discarded night
vision lenses and Bradley Fighting Vehicle turret windows into “3,000 kilograms of 99.999

64 DLA, “Depot Information,” at https://www.dla.mil/Strategic-Materials/Resource/. Following World War II, NDS
materials were maintained at hundreds of facilities nationwide: for example, a 1961 stockpile report lists 46 million
tons of strategic and critical materials stored at 58 military depots; 22 General Services Administration depots; 10 other
government-owned sites; 39 industrial plant sites; 16 leased commercial sites; and 68 commercial warehouses. See
Executive Office of the President,
Stockpile Report to the Congress: January – June 1961, October 1961, p. 5. In 1997,
after declaring 99% of remaining NDS inventories “excess material,” DLA-SM “established a long-range plan to
vacate 66 sites.” See U.S. General Accounting Office,
National Defense Stockpile: improved financial plan needed to
enhance decision making, January 2001, p. 4. At some of these locations, “past material storage and handling practices
allowed chemical constituents to leach into soil and water.” See DOD,

remediation efforts at these sites through its annual reports and congressional briefings.

demand for purified germanium.”69 This recovered germanium is to be stored in the NDS for
emergency use.70
Also reported in FY2022, DLA-SM’s boron carbide recovery program is to turn demilitarized
body armor plates “that would have been landfilled” into a processed powder stored in the NDS.
In an emergency, this powder could be recast into new hard armor plates. DOD reportedly
disposes of approximately 120,000 body armor plates each year, with 30% of these plates
reportedly containing high concentrations (up to 90%) of boron carbide.71
To the extent that recovery operations reliably yield large quantities of certain strategic and
critical materials, these operations may be assessed as potential complements or alternatives to
other domestic or foreign sources of supply in emergency scenarios.72
Analytic Support to DLA-SM: Institute for Defense Analyses
DLA-SM also plays a central role in the interagency effort to analyze alternative sources of
supply through stockpile planning. To assess stockpile requirements DLA-SM contracts with a
federally funded research and development center (FFRDC), the Systems and Analyses Center
(SAC), run by the Institute for Defense Analyses (IDA). Since June 1988, SAC has constructed
the interagency analytic backbone of the National Defense Stockpile, known as the Risk
Assessment and Mitigation Framework for Strategic Materials (RAMF-SM).73
RAMF-SM is “a set of models, procedures, and databases” designed to recommend which
strategic and critical materials should be stockpiled, and in what quantities.74 The framework
incorporates a combat scenario provided by the Office of the Under Secretary of Defense for
Policy; data on equipment losses, weapons platform requirements, and consumables provided by
the Joint Staff in coordination with the military departments; and data from interagency partners
(including the intelligence community) and industry stakeholders to estimate what may happen to
supply chains for candidate materials under certain conditions.75
partnered with the Anniston Army Depot to implement this project. See DLA, “Strategic Material Recovery and Reuse
Program (SMRRP),” website at https://www.dla.mil/Strategic-Materials/Business/Recycling-and-Reuse-Program-

annual demand).

Emergency Access to Strategic and Critical Materials: The National Defense Stockpile
The baseline scenario for these calculations is termed the “base case” and by law must be “a
military conflict scenario consistent with the scenario used by the Secretary [of Defense] in
budgeting and defense planning.”76 Stockpile models must also encompass “those strategic and
critical materials necessary for the United States to replenish or replace, within three years of the
end of the military conflict scenario…all munitions, combat support items, and weapons systems
that would be required after such a military conflict.”77
Ultimately, outputs from RAMF-SM provide decision support to the National Defense Stockpile
Manager and Strategic and Critical Materials Board of Directors.78 In the event that DOD
leadership uses model outputs to justify acquiring or selling stockpile materials, the NDS has
built-in bureaucratic mechanisms for anticipating the market impacts of these actions via the
board and the NDS Market Impact Committee.
NDS Market Impact Committee79
Section 3314 of the National Defense Authorization Act for Fiscal Year 1993 (P.L. 102-484)
established an interagency Market Impact Committee (MIC) to advise the National Defense
Stockpile Manager on “the projected domestic and foreign economic effects of all acquisitions
and disposals of materials from the stockpile.” Co-chaired by the Departments of Commerce and
State, the MIC includes additional representatives from the Departments of Agriculture, Defense,
Energy, Homeland Security, the Interior, and the Treasury.80
The MIC facilitates outreach to industry and public stakeholders by periodically publishing a
notice of inquiry and request for public comments in the
Federal Register. Such a notice was
community.” For an overview of Joint Staff activities that may generate data informing RAMF-SM, see DOD,
Chairman of the Joint Chiefs of Staff Instruction (CJCSI) 3100.01E, Joint Strategic Planning System, May 21, 2021;
and DOD,
DOD Directive (DODD) 8260.05, Support for Strategic Analysis, July 7, 2011. The latter describes
organizational relationships for generating baseline conflict scenarios, incorporating data from current operations,
Combatant Commander plans, force management decisions, and intelligence estimates. As with any sophisticated
modeling and simulation enterprise, RAMF-SM can be extremely sensitive to assumptions, constraints, and empirical
uncertainty. See Justin M. Lloyd et al., “Methods in macroeconomic forecasting uncertainty analysis: an assessment of
the 2015 National Defense Stockpile Requirements Report,”
Mineral Economics, vol. 31, 269-281 (2018) and IDA,

strategic and critical materials from specific countries under emergency conditions.
76 50 U.S.C. §98h-5(b).
77 50 U.S.C. §98h-5(c). This subsection also requires DOD to consider the impact of “alternative mobilization periods”
and “a range of other military conflict scenarios addressing potentially more serious threats to national security” than
the base case scenario, reporting to Congress the effect these alternatives would have on stockpile requirements. The
FY2023 James M. Inhofe National Defense Authorization Act also required DOD to assess “the strategic materials
required…to sustain combat operations for not less than one year against the pacing threat identified in the National
Defense Strategy” (i.e., China), and to submit a classified report on the results by January 15, 2024. See P.L. 117-263
§1415 and 50 U.S.C. §98d Statutory Notes and Related Subsidiaries.
78 RAMF-SM output recommendations are provided to DOD senior leaders, who may or may not request congressional
appropriations in a given year to acquire some portion of the materials estimated to be in shortfall.
79 From October 1992 to December 2022, Congress utilized 50 U.S.C. §98h-1 to require a Market Impact Committee to
perform roles outlined in this section. In December 2022, P.L. 117-263 §1411 replaced the MIC’s role in 50 U.S.C.
§98h-1 with a Strategic and Critical Materials Board of Directors. The MIC has continued its public-facing activities
from December 2022 to present; however, pending publication of the board’s membership and by-laws, the role of the
MIC in stockpile management moving forward is uncertain.

Emergency Access to Strategic and Critical Materials: The National Defense Stockpile
published on September 5, 2023, for the NDS FY2025 Annual Materials Plan.81 These notices
provide a list of materials being considered for “acquisition, disposal, upgrade, conversion,
recovery, reprocessing, or sales” along with a “maximum quantity” of each material that might be
affected over the course of the fiscal year in question.
These public notices emphasize an important and historically contentious feature of the Stock
Piling Act: “The NDS is a strategic stockpile, not an economic stockpile. It is not intended to
influence prices in the market or insulate private industry from supply shocks.”82 The Stock Piling
Act states: “The purpose of the National Defense Stockpile is to serve the interest of national
defense only. The National Defense Stockpile is not to be used for economic or budgetary
purposes.”83 This congressional declaration followed decades of politically contentious stockpile
acquisition and disposal decisions, which some analysts, industry associations, and Members of
Congress argued unduly shaped market prices or implemented economic and foreign policy.84
To the extent that NDS acquisitions or sales play a role in U.S. supply chain resilience policies in
coming years, the MIC and Board of Directors may face potential ambiguity between future
stockpile transactions intended “for national defense only” and those intended (or projected) to
have economic impacts favoring nascent domestic industries, insulating the national technology
and industrial base from supply shocks, or engaging in strategic competition with foreign sources
of supply.85
NDS Transaction Fund (Resource Management)
The National Defense Stockpile Transaction Fund (NDSTF) was established by the Strategic and
Critical Materials Stock Piling Revision Act of 1979 (P.L. 96-41) to finance authorized NDS
operations without requiring annual congressional appropriations. The NDSTF houses “all
moneys received from the sale of materials in the stockpile,” including any strategic and critical
materials resulting from “excess materials made available for recovery purposes by other Federal
81 Ibid.
82 Ibid.
83 50 U.S.C. §98a(c). The prohibition on using the NDS for budgetary purposes references efforts to use NDS
Transaction Fund assets to reduce annual budget deficits and the like.
84 The earliest stockpile reports to Congress, declassified in the early 2000s, emphasize that planned stockpile
acquisitions should be kept secret because “public knowledge of stockpile procurement plans would affect the prices at
which urgently needed materials would be offered to the Government.” See DOD,
Stockpiling Report by the Munitions
Board to The Congress, January 23, 1948, front matter. For contemporary analysis of stockpile politics and market
impacts, see Glenn Herald Snyder,
Stockpiling strategic materials: politics and national defense (San Francisco, CA:
Chandler Publishing Company, 1966), p.3; and Patricia Elaine Perkins, “The United States strategic stockpile and price
determination in international metals markets,” (Ph.D. diss., University of Toronto, 1989), arguing that the impact of
the NDS on market prices historically depended on its size over time. The American Mining Congress in 1976 testified
to Congress that the stockpile had “an extremely disruptive influence in the market for metals and minerals” and that
most mining industry CEOs “would just as soon have no [national] stockpiles at all.” See Ibid., p. 29 and U.S.
Congress, Joint Committee on Defense Production,
Hearings: Defense Industrial Base, Part 3: New Stockpile
Objectives, 94th Cong., 2nd sess., November 24, 1976, pp. 64, 80). During these hearings, committee chair Senator
Proxmire stated: “Moreover, the history of our stockpiles is replete with examples of their use or abuse for budget
balancing, for price stabilization and for almost every other purpose other than the only legal one—strategic
mobilization.” Ibid., p. 1.
85 The NDS Board of Directors is chaired by the Assistant Secretary of Defense for Industrial Base Policy, whose
priorities include executing authorities under 10 U.S.C. §4811 to ensure supply chain resilience in the national
technology and industrial base, i.e., ensuring the capacity of private industry to withstand supply shocks. In addition,
Section 1 of E.O. 14051, “Designation to Exercise Authority over the National Defense Stockpile,” 86
Federal Register 60747, October 31, 2021 frames the NDS as “a model for the private sector” to “create a buffer against potential
shortages and import dependencies.”

agencies.”86 50 U.S.C. §98h sets out a number of lawful uses of NDSTF funds “(subject to such
limitations as may be provided in appropriations Acts),” from acquisition, maintenance, and
disposal of materials to quality control testing, facility and infrastructure improvement, pay of
employees, research and development, and environmental remediation.
During the post-Cold War era, sales of excess materials from the stockpile generated billions of
dollars in revenue. Rather than maintain large cash reserves in the NDS Transaction Fund,
Congress from 2002 to 2022 “transferred more than $6 billion from the Transaction Fund to the
General Fund and other mandatory programs unrelated to the NDS mission.”87 As a result, DOD
has stated that current stockpile inventories and unobligated balances in the fund may not cover
anticipated program requirements.88 One method of increasing the Transaction Fund balance is
through appropriations.89
In general, “Moneys in the fund shall remain available until expended.”90 However, the FY2022
and FY2023 appropriations acts added a total of $218.5 million to the NDSTF with a two-year
period of availability, meaning that these funds must be placed on a contract or otherwise
obligated within two fiscal years of legislative enactment and fully disbursed within seven fiscal
years.91 NDSTF resource managers apply internal controls to appropriated funds to facilitate
contracting actions and obligation planning within this period of availability.
NDS Research and Development Activities
Title 50 U.S.C. §98g requires the National Defense Stockpile Manager (as the President’s
designee) to “make scientific, technologic, and economic investigations” to develop new
domestic sources of supply and new production methods for strategic and critical materials, along
with
substitutes for “essential ores and mineral products.”
DLA-SM provides grants to universities and sign contracts with federal research and
development (R&D) agencies and private companies to perform R&D-type activities:92
• Development, mining, preparation, treatment, and utilization of ores and other
mineral substances.
86 50 U.S.C. §98h; 50 U.S.C. §98e(b)(5)-(6). Historically, P.L. 77-76 of May 28, 1941 amended the original Stock
Piling Act of 1939 “so as to provide for a revolving fund, or the availability for re-use of all proceeds from sales of
material from the stockpile.” However, Congress reversed this decision with P.L. 79-520 of July 9, 1946 in favor of
placing all sales revenue into “the general receipts of the Treasury.” Rather than introducing a new approach to
stockpile resource management in 1979, Congress was largely reinstating an approach from WWII. See Department of
Defense,
Stockpiling report by the Secretary of War and the Secretary of the Navy to the Congress pursuant to section
4 of public law 520, 79th Congress covering operations from 7 June 1939 to 31 December 1946, 23 January 1947, p. I-

89 Alternatively, Congress may authorize other revolving funds to purchase strategic and critical materials for transfer

• Development of sources of supplies of agricultural materials; use of agricultural
commodities for manufacture of materials.
• Development of sources of supply of other materials; development or use of
alternative methods for refining or processing materials in the stockpile.
• Grants and contracts to encourage conservation of strategic and critical materials.
Historically, the U.S. Department of the Interior’s U.S. Geological Survey (USGS) has performed
many of the R&D activities related to domestic development and mining.93 The U.S. Department
of Agriculture similarly performed investigations into various agricultural commodities once
deemed strategic and critical materials, such as wool, vegetable tannins, and opium.94
As DOD weapons systems have increased in technological sophistication, a wider array of R&D
performers, including universities, have obtained DLA-SM contracts and grants.95 In FY2022,
DLA-SM reported seven R&D projects totaling $3.7 million, including a contract with the
Department of Energy’s Oak Ridge National Laboratory (ORNL) to test a new process for
recovering critical rare earth elements from discarded electronics hardware (i.e., e-waste).96
In addition, DLA-SM seeks to qualify (i.e., certify) industrial operations to provide reliable
alternative sources of supply for strategic and critical materials. To that end, in FY2022 DLA
reported “a qualification program of antimony trisulfide from Mexico to replace the only
qualified source located in China.”97
Current NDS Transaction Fund unobligated cash balances ($326 million projected for end of year
FY2024) may provide ample resources for the National Defense Stockpile Manager to accelerate
R&D efforts and qualify additional industrial operations.98 In addition, 50 U.S.C. §98g may
authorize DOD to leverage advances in biomining and biomanufacturing of strategic and critical
materials to acquire NDS inventories.99
93 For current U.S. interagency critical materials R&D policy outside the Stock Piling Act framework, see 30 U.S.C.
Chapter 28—Materials and Minerals Policy, Research, and Development. Until closure in 1996, the Department of
Interior’s Bureau of Mines performed NDS R&D work alongside USGS. In 1996, these Bureau of Mines functions
were returned to the USGS. See USGS, “How can I find U.S. Bureau of Mines publications?” at

Emergency Access to Strategic and Critical Materials: The National Defense Stockpile
Biennial Report on Stockpile Requirements103
DOD delivers recommendations every other year to Congress on stockpile requirements,
disclosing the “national emergency planning assumptions” underlying its analytic process. DOD
is required to disclose:
• The length and intensity of the assumed military conflict.
• The military force structure to be mobilized.
• The losses anticipated from enemy action.
• The military, industrial, and essential civilian requirements to support the
national emergency.
• The availability of supplies of strategic and critical materials from foreign
sources during the mobilization period, the military conflict, and the subsequent
period of replenishment, taking into consideration possible shipping losses.
• The domestic production of strategic and critical materials during the
mobilization period, the military conflict, and the subsequent period of
replenishment, taking into consideration possible shipping losses.
• Civilian austerity measures required during the mobilization period and military
conflict.
The biennial report must also include “an examination of the effect that alternative mobilization
periods…as well as a range of other military conflict scenarios addressing potentially more
serious threats to national security, would have on the Secretary's recommendations.”104 The
FY2023 NDAA (P.L. 117-263) §1415 further required DOD to submit with its 2023 biennial
report a classified report on the strategic materials required to sustain a one-year-long armed
conflict with the pacing threat identified in the National Defense Strategy (i.e., China).105 The
provision requires DOD to acquire the highest priority strategic and critical materials identified in
this scenario “subject to the availability of appropriations.”106
The Stock Piling Act does not establish requirements for ensuring this biennial assessment
integrates armed conflict scenario data emerging from other congressional reporting
requirements. For example, by February 2024 DOD is required by law (10 U.S.C. §118b) to
submit to Congress a classified National Defense Sustainment and Logistics Review containing
long-term strategic assessments (5-, 10-, and 25-years out) of global defense posture elements,
defense industrial base capabilities, supply chain risks, and logistics assets in realistic armed
conflict scenarios. Inasmuch as these assessments contain the highest quality, most
comprehensive data integration DOD can deploy for strategic analysis, these data may be
available for integration into future biennial NDS requirements assessments.
103 Bullet points in this subsection are quotations from 50 U.S.C. §98h-5(b). The FY2017 NDAA (P.L. 114-328)
§1061(i)(30) set a termination date (December 31, 2021) for this biennial report. The White House’s 100-day supply
chain review of DOD strategic and critical materials recommended that Congress reinstate this reporting requirement
(The White House,
Building Resilient Supply Chains, Revitalizing American Manufacturing, and Fostering Broad-
Based Growth: 100-Day Reviews under Executive Order 14017, June 2021, p. 201). The FY2022 NDAA (P.L. 117-81)

Issues Facing Congress
The following section considers issues that Congress may face involving National Defense
Stockpile legislation and oversight.
Assessing NDS Funding Tradeoffs
Since 2022, executive branch budget requests and legislative activity related to NDS acquisitions
have displayed considerable variability. DOD requested $253.5 million in new budget authority
for NDS acquisitions in FY2023 (and $7.6 million for FY2024).107 The enacted FY2023 NDAA
(P.L. 117-263) authorized $1.0 billion, while the Consolidated Appropriations Act, 2023 (P.L.
117-328) appropriated $93.5 million.108 Congress may wish to assess the extent to which resource
allocation tradeoffs are currently affecting national stockpile strategy.
There is currently no statutory requirement for the President’s Budget Request to include plans
for stockpiling 100% of estimated material shortfalls of strategic and critical materials. The Risk
Assessment and Mitigation Framework for Strategic Materials (RAMF-SM) generates estimated
requirements and provides these estimates to senior leaders as decision support in budget
planning. Executive branch officials may elect not to request funds to fill estimated shortfalls.
DOD budget decisions may consider that most shortfalls cover nondefense demand.
The executive branch may face tradeoffs in assessing whether to request new budget authority for
NDS acquisitions. To the extent that budget toplines for discretionary defense spending are fixed,
dollars spent storing raw materials for nondefense critical infrastructure demand in a national
emergency may be viewed as competing with requirements for present-day military operations
and equipment maintenance, procurement of weapons, or research and development of next-
generation military platforms.
Congress may also face resource allocation tradeoffs in considering further NDS appropriations,
with budget authority for emergency stockpile acquisitions competing with other national
priorities.
Both the executive branch and Congress may face variation among expert opinions in assessing
the comparative value of the National Defense Stockpile. To the extent that emergency raw
material stockpiles provide deterrence value, investments in strategic weapons, additional war
reserve materiel, enhanced warfighter training, or diplomatic engagement may be assessed as
providing greater or lesser deterrence value. Similarly, to the extent that emergency raw material
stockpiles increase supply chain resilience, other investments that increase near-, mid-, or long-
term domestic industrial base capacity, incentivize
friend-shoring of value chains, or strengthen
global maritime logistics may be viewed as providing greater or lesser supply chain resilience.
And to the extent that emergency raw material stockpiles facilitate whole-of-government
emergency preparedness, other investments in non-DOD federal agencies, nondefense national
stockpiles, or partnerships with nondefense critical infrastructure industries may be viewed as
providing greater or lesser whole-of-government emergency preparedness.

Emergency Access to Strategic and Critical Materials: The National Defense Stockpile
DOD’s 2021 biennial stockpile assessment stated that “stockpiling is only a temporary stopgap
mitigation strategy” for some materials.109 Comprehensive risk mitigation, according to the
assessment, may require alternative resource allocations to “implement a permanent solution,”
including Title III Defense Production Act and Industrial Base and Sustainment (IBAS)
investments.110
Given budget constraints, techniques for assessing these tradeoffs and improving resource
allocation may become important tools for national security policymaking.
Determining Which National Emergency Scenarios Should be Used
to Generate NDS Requirements
The National Defense Stockpile Manager currently establishes biennial stockpile requirements
using a base case armed conflict scenario consisting of one year of active combat and three years
of post-conflict industrial replenishment. Congress may wish to consider whether current strategic
threat assessments justify modification of base case scenarios.
For example, Section 1411 of the House-passed FY2024 NDAA (H.R. 2670) would triple the
assumed length of active combat in the scenario to three years while maintaining a three-year
industrial replenishment period. In addition, this provision would require stockpile planners to
model the “total mobilization of the economy of the United States” and encourage DOD to obtain
stockpiles sufficient to meet these new requirements “on or after” January 1, 2028.111
A historical perspective may assist policymakers in anticipating the general effect of this
modified planning scenario and acquisition schedule on biennial stockpile requirements.112
In December 1987, the National Defense Authorization Act for Fiscal Years 1988 and 1989 (P.L.
100-180) established a three-year active conflict scenario (modeled on sustained conventional
global war with a contemporary adversary). The three-year industrial replenishment period was
only established as a stockpile requirement in 1996 (P.L. 104-201 §3311) alongside a reduction in
the active conflict period. In March 1988, DOD reported that the shift to a three-year active
combat period “(at 31 March 1988 prices) would require acquisition of additional materials
valued at approximately $12.3 billion” in addition to the $7.1 billion in non-excess inventory the
NDS already had on hand.113
In other words, DOD reported to Congress in 1988 that strategic and critical materials shortfalls
for a contemporary three-year, high-intensity active combat scenario would amount to $19.4
billion, without providing stockpiles for a three-year industrial replenishment period.
Strategic and critical materials shortfalls in the 2024 to 2028 timeframe may differ in many
respects from requirements in 1988. Nevertheless, NDS requirements would increase

111 The provision states that stockpiled materials “should be” sufficient “on or after January 1, 2028” to meet “the
national defense needs of the United States, for a period of not less than three years” “necessitating the total
mobilization of the economy of the United States for a sustained conventional global war of indefinite duration.” See
H.R. 2670 §1411.
112 In practice, the language in the House-passed NDAA provision admits of several possible operationalizations, which
may require DOD planners to clarify congressional intent to facilitate implementation and assessment.

significantly if Congress required stockpile planners to model a three-year sustained global
conventional war featuring total mobilization of the U.S. economy while maintaining a three-year
post-conflict industrial replenishment requirement.114 As previously noted, a gap of $13.5 billion
already exists between current NDS assets and estimated shortfalls in a base case national
emergency scenario modeling one year of active conflict.
Given a desire to strategically balance national defense stockpiling and national security
preparedness with all other national priorities, Congress may wish to assess several alternative
base case scenarios to decide its resource allocation preferences.
Assessing market impacts of rapid stockpile acquisition strategies
The current gap between National Defense Stockpile assets and estimated material shortfalls is
$13.5 billion, primarily for non-defense critical infrastructure demand rather than defense
industrial base requirements.115 The 118th Congress is currently considering a legislative proposal
in the House-passed version of an FY2024 NDAA (H.R. 2670 §1411) that historical precedent
suggests could triple estimated shortfalls, while adding a requirement for DOD to acquire
materials to mitigate these shortfalls on or after January 1, 2028.116 Current shortfalls and pending
legislative proposals therefore raise questions about the potential market impacts of rapid
stockpile acquisitions.
There are several ways to obtain NDS inventories:
•
Market exchange: Historically, the primary method of obtaining stockpile
materials has been purchasing non-fuel mineral commodities at market prices
from foreign sources, adhering to standard federal procurement practices.117
•
Barter.: 50 U.S.C. §98e also authorizes the use of barter when practical; for
example, “To the extent otherwise authorized by law, property owned by the
United States may be bartered for materials needed for the stockpile.”118
•
Recycling and Recovery. Since FY2014, Congress has authorized NDS
operations to recover strategic and critical materials from federal agency end-of-
life scrap and excess equipment such as night vision goggles and Bradley
Fighting Vehicle turret windows.119
In the absence of multi-billion-dollar appropriations, barter and recycling and recovery operations
may present alternative pathways for bridging NDS material shortfalls.
Congress could assess a range of barter options. These options would typically obtain strategic
and critical materials from international markets at negotiated prices in exchange for goods or
services rather than cash payment. As a result, the Strategic and Critical Materials Board of
Directors and NDS Market Impact Committee may assess the market impacts of rapid acquisition
114 CRS email correspondence with NDS planners at Institute for Defense Analyses, July 6, 2023, generally
corroborated that the House-passed provision in question, if enacted, would increase stockpile requirements, though
precise amounts were not discussed.

via barter in a manner similar to acquisition via appropriations. In both cases, assessing market
impacts involves estimating whether stockpile acquisitions would unduly affect commodity prices
over time.
NDS recycling and recovery operations may provide a way to acquire shortfall materials while
developing new sources of supply. To the extent that recycling and recovery operations could
provide reliable domestic sources of supply under wartime conditions, these operations may
contribute to reducing NDS biennial shortfalls.
Section 1512 of the Senate-passed version of an FY2024 NDAA would amend the Stock Piling
Act to authorize DOD to co-fund new recycling and recovery business model designs (i.e.,
“bankable feasibility studies”).120 The White House’s 100-day strategic and critical materials
supply chain review recommended a “government-wide” recycling and recovery program to
obtain strategic and critical materials from federal data warehouse e-waste.121 The Strategic and
Critical Materials Board of Directors, NDS Market Impact Committee, and Congress may wish to
assess the potential market impacts of rapidly scaling up such operations.
Adapting stockpiles to anticipate and incorporate technological
innovation
In a June 1946 address to the Army Ordnance Association, Army Chief of Staff and future
President Dwight Eisenhower pointed out a potential weakness of a national stockpiling strategy.
He stated: “Security is not static. Military stockpiles can become junk because of a single
scientific development and the security they lend can be wiped out by a single laboratory
experiment.”122 This remark calls attention to the limitations of stockpiling strategies that fail to
anticipate or rapidly adapt to emerging technologies and technological innovation.
The current statutory framework for the NDS combines short-term stockpile planning with a mid-
and long-term vision, authorizing the use of NDS funds for “scientific, technologic, and economic
investigations” that generate “more efficient methods of production” and “develop new materials
for the stockpile.”123 Thus, apart from policy proposals that may increase or decrease stockpile
quantities, what Eisenhower later called “realistic stockpiling” might take the form of enhanced
coordination of such scientific, technological, and economic investigations.
DOD Chief Technology Officer / Under Secretary of Defense for Research &
Engineering
There is currently no strategic planning, operations management, or research and development
(R&D) role stipulated in the Stock Piling Act for the DOD Chief Technology Officer
(CTO)/Under Secretary of Defense for Research and Engineering (USD(R&E)).124 The Defense
Logistics Agency and Under Secretary of Defense for Acquisition and Sustainment (USD(A&S))

development of R&D projects pursuing alternative materials and domestic sources of supply. As
part of these R&D efforts, DLA-SM currently contracts, for example, with the Army Research
Laboratory to develop new refinement and production processes. The NDS Board of Directors is
chaired by the Assistant Secretary of Defense for Industrial Base Policy within USD(A&S).
Congress could assess the costs and benefits of authorizing, encouraging, or requiring
participation from the DOD CTO/USD(R&E) in aspects of NDS strategic planning, operations, or
R&D efforts. Offices within the DOD CTO/USD(R&E) hierarchy generate insight into emerging
trends in critical technology areas;125 innovation in industrial processes;126 trends in strategic and
critical material composition in DOD weapons systems and munitions; strategic intelligence and
analysis related to emerging adversaries;127 cutting-edge supply chain mapping methodologies;128
digital repositories of technical information; and access to “strategic capital,” engaging vendors
and bringing external investors into direct conversation with engineers developing possible new
technical solutions to existing operational challenges.129
Congress may consider to what extent CTO/USD(R&E) areas of specialization may add value to
NDS strategic planning, operations, and R&D such as:
• Current efforts to obtain strategic and critical materials from recycling and
recovery operations.130
• “Transportation, processing, refining, storage, security, maintenance, rotation,
and disposal of materials.”131
• Materials development and research, including alternative methods to convert
stockpile materials into more suitable forms.132
• Development of sources of supplies of agricultural materials; use of agricultural
commodities (e.g., biotechnology or synthetic biology approaches).133
• Approaches to grantmaking at academic institutions for purposes of assessing
potential material substitutes or “more efficient methods of production” and
material usage.134

as biotechnology or nanotechnology; or maintain them using additive manufacturing or artificial intelligence.

Emergency Access to Strategic and Critical Materials: The National Defense Stockpile
Congressional action is not necessarily required for increased CTO/USD R&E involvement in
NDS planning and operations. The Stock Piling Act provides the Strategic and Critical Materials
Board of Directors considerable flexibility in expanding Board membership, adopting by-laws,
and considering matters assigned to it by the Board chair.135 The Board itself may thus consider
the costs and benefits of integrating DOD CTO/USD(R&E) into Board membership, initiatives,
or execution of duties established in 50 U.S.C. §98h-1(c). Since the Board was established
recently with the FY2023 NDAA (P.L. 117-263 §1411), Congress could consider periodically
reviewing Board action to assess the extent of CTO/USD R&E involvement in NDS planning and
operations.
Private sector stockpiles of strategic and critical materials
The Biden Administration has stated that increasing inventories in the National Defense Stockpile
could “provide a model for the private sector” to increase inventories of raw materials for
enhanced supply chain resilience, “while recognizing that private sector stockpiles and reserves
can differ from government ones.”136 Congress may consider assessing incentive structures in the
private sector that affect industry behavior vis-à-vis stockpiling strategic and critical materials.
Public policies and industry behaviors that reliably increase the domestic availability of strategic
and critical materials during a national emergency may tend to reduce NDS requirements.137
However, peacetime conditions may disincentivize emergency stockpiles of strategic and critical
materials among competitive firms. Having too much raw material on hand at any given time may
negatively affect a company’s balance sheet and overall financial performance, imposing costs
that could otherwise be redirected to more productive activity.
Supply chain volatility associated with the COVID-19 pandemic has triggered a rethinking of
inventory management principles and supply chain risk management throughout the private
sector.138 To the extent that companies
expect supply chain volatility in the future, they may opt
for increased inventories of certain raw materials in anticipation of future supply shortages.
However, as expected volatility decreases, safety stocks and emergency inventory levels may tend
to decrease. 139 When NDS planners generate stockpile requirements, they factor in an expectation
that domestic private sector companies will likely procure additional stocks of strategic and
critical materials
during a national emergency “without government intervention.”140
135 50 U.S.C. §98h-1.
136 see E.O. 14051, “Designation to Exercise Authority over the National Defense Stockpile,” 86
Federal Register 60747, October 31, 2021, Section 1.
137 As discussed throughout this report, inventories in the National Defense Stockpile are based on estimates of military
and essential civilian demand under national emergency conditions. DOD estimates the expected quantity of strategic
and critical materials that will be available in an armed conflict scenario and compares this quantity to the estimated
total military and essential civilian demand for strategic and critical materials for the duration of the scenario. The
difference between the total demand and the estimated availability produces a “material shortfall” that can be used to
justify new stockpile acquisitions (or disposals).
138 For example, during periods of high volatility, “just-in-time” inventory management tends to yield to “just-in-case”
inventory management, characterized by increased safety stocks of key production inputs. However, as volatility
decreases, many firms revert back to “just-in-time” inventory management due to pressures on financial performance.

2023 in Board of Governors of the Federal Reserve System, “Beige Book – January 18, 2023,” online resource at

Emergency Access to Strategic and Critical Materials: The National Defense Stockpile
Congress from 1984 to 2020 expressed its finding that “establishing critical materials reserves,
both by the public and private sectors
…represents one means of responding to the genuine risks
to our economy and national defense from dependency on foreign sources.”141 Since the 1980s,
the Executive Office of the President has developed and maintained interagency organizations to
pursue policies rooted in similar findings.142
Congress may wish to assess the extent to which current federal policies incentivize increased
domestic availability of strategic and critical materials prior to, during, or following a national
emergency.
Nondisclosure agreements with industry for robust NDS planning
Congress could also consider assessing DOD’s current practices for soliciting and utilizing
microeconomic, firm-level data in generating National Defense Stockpile requirements.
In practice, NDS planning involves two levels of industry data, referred to as Study List 1 (SL1)
and Study List 2 (SL2).143 SL1 data are macroeconomic data from the U.S. Department of
Commerce and U.S. Geological Survey, describing flows of natural resources, goods, and
finances for approximately 150 materials affecting 350 economic sectors and industry
classifications.144 SL2 data are microeconomic, individual firm-level data provided by domestic
companies that mine, process, or use strategic and critical materials. SL2 data typically include
open source and proprietary information related to the supply chains of individual companies in
critical infrastructure sectors.145 To obtain SL2 data, the Institute for Defense Analyses (IDA)
routinely signs nondisclosure agreements (NDAs) with such companies. In practice, many
companies are hesitant to provide proprietary SL2 data to stockpile planners.146
Congress may wish to assess to what extent relevant companies provide SL2 data for NDS
planning, and whether there is currently a robust mechanism, either in statute or in current
organizational practice, to solicit, obtain, secure, and fully utilize large quantities of SL2 data in
biennial assessments of stockpile requirements. Congress could also assess incentive structures
among individual firms to provide or not provide DOD with SL2 data.
Addressing material weaknesses in NDS financial audits
Ernst & Young’s independent audit of DLA’s FY2022 financial operations disclosed material
weaknesses and significant deficiencies in several aspects of NDS resource management.147
141 This finding from the National Critical Materials Act of 1984 (P.L. 98-373 §202; 30 U.S.C. §1801(a)(6)) was
repealed by the Consolidated Appropriations Act, 2021 (P.L. 116-260 §7002(n)(1)).
142 From 1984 through 2020, the National Critical Materials Council (NCMC) exemplified such an organization. See 30
U.S.C. §1801,
et. seq. (prior to Supplement II of the 2018 edition). The Consolidated Appropriations Act, 2021 (P.L.
116-260 §7002) established a framework whereby the Office of Science and Technology Policy’s National Science and
Technology Council (NSTC) subsumed research coordination activities of the NCMC. See 30 U.S.C. §1604(b).
