more than the Biden Administration’s $752.4 billion request for programs covered by the act.
Management Policy
Compared to the corresponding funding legislation for FY2022, the FY2023 bill provides an

increase of $68.9 billion (9.6%) for defense programs (see table below).

Neither the House nor the Senate passed a freestanding FY2023 defense appropriations bill. The
House Appropriations Committee (HAC), after 18 Subcommittee on Defense hearings from March to May 2022, voted 32-26
on June 22, 2022, to introduce such a bill (H.R. 8236) with an accompanying report (H.Rept. 117-388) comparing committee
funding decisions to DOD’s requested amounts. Upon introduction, the House took no further action on that bill. The Senate
Appropriations Committee (SAC) held eight Subcommittee on Defense (SAC-D) hearing sessions from March to June 2022.
Concurrent with publication of the SAC Chairman’s mark on the committee’s website, SAC-D Chairman Senator Jon Tester
introduced an FY2023 defense appropriations bill (S. 4663) on July 28, 2022, on which neither the full Appropriations
Committee nor the Senate took further action.
Bicameral, bipartisan negotiations produced a final version of the defense appropriations bill, which, along with the texts of
11 other appropriations bills, was substituted for the text of H.R. 2617 by process of amendment. The defense bill was
designated as Division C of the resulting Consolidated Appropriations Act, 2023, which the Senate passed on December 22,
2022, by a vote of 68-29 (Record Vote Number: 421). The House passed the bill on December 23, 2022, by a vote of 225-
201-1 (Roll no. 549). On December 29, 2022, the President signed H.R. 2617, which was enrolled as P.L. 117-328.

a. The Consolidated Appropriations Act, 2023 (P.L. 117-73) utilized an “amendments-between-the-Houses”
process rather than a conference committee to resolve differences between bil versions. Therefore, the
“explanatory statement” referred to throughout this report is not a typical joint explanatory statement
generated by a conference committee. Rather, it refers to the explanatory statement accompanying the
enacted bil in the Congressional Record, which states that it “shall have the same effect with respect to the
allocation of funds…as if it were a joint explanatory statement of a committee of conference.” See Senate
debate, Congressional Record, vol. 168, No. 198 (December 20, 2022), p. S7820.
There are hundreds of differences between the Biden Administration’s budget request and the
enacted bill over funding for particular DOD programs and activities. However, a relative handful
of broad issues account for much of the difference between the FY2023 budget request and the
budget authority appropriated in the enacted bill. These differences can be analyzed in terms of
upward or downward adjustments to the Administration’s base budget request.3
Selected Upward Adjustments
Inflation Adjustments
Because DOD develops each year’s budget request over a two-year year cycle within the
Planning, Programming, Budgeting, and Execution (PPBE) process, economic assumptions
driving DOD’s budget request just prior to budget submission (e.g., in late 2021 or early 2022)
may not match congressional expectations for future price inflation during legislative hearings,
floor consideration, or bicameral negotiations (e.g., from early 2022 through bill passage).4 The
enacted bill includes a total of $8.0 billion in new budget authority intended to cover projected
cost increases attributed to higher-than-anticipated inflation. These adjustments include personnel
($1.8 billion) and non-personnel ($6.2 billion) cost inflation (see Table 3).
Personnel-related inflation adjustments address cost growth affecting military personnel
allowances for subsistence, housing, dislocation, basic needs, and temporary lodging expenses.5
Inflation adjustments outside Military Personnel appropriations address cost growth for utilities
and daycare, military grocery stores (i.e., commissaries), military health care, fuel, and cost
growth common to acquisition programs.6

3 DOD’s Financial Management Regulation (FMR) refers to upward adjustments to individual programs as
“Congressional Adds.” See DOD, Financial Management Regulation, DOD 7000.14-R, Volume 2B Chapter 5, p. 5-16
at https://comptroller.defense.gov/fmr/. In practice, Congress may utilize dozens of unique phrases to designate upward
and downward adjustments to the presidential administration’s requests in funding tables accompanying an enacted
appropriations bill, such as “program increase.” Other terms have precise technical definitions, such as “Rescissions,”
whereby Congress takes away remaining obligation authority from prior year appropriations accounts that are both
unexpired and contain unobligated balances. The DOD FMR accounts for the totality of upward and downward
adjustments at the line-item level in the following categories: Congressional General Reductions; Congressional
Directed Reductions; Congressional Rescissions; Congressional Adds; Congressional Directed Transfers [between
appropriations accounts]; and Other Adjustments. See Ibid., p. 5-17.

for Jeep-like HMMWVs (“Hum-vees”) for the Army National Guard, and $53 million for new
radars for Air National Guard F-16 fighter aircraft.8
Research and Development
The enacted defense appropriations bill provides hundreds of program increases for DOD-funded
science and technology (S&T) research projects. S&T research, much of it performed by
universities, focuses on basic research, applied research, and advanced technology development
that could be incorporated into the design of future military hardware, as opposed to research
associated with specific prototypes undergoing test and evaluation or equipment already in the
field or slated for procurement.9
The enacted bill provides a net total of $9.9 billion above the amount requested across the
research, development, test, and evaluation (RDT&E) portfolio.10 Selected upward adjustments
include nearly 600 line-item program increases totaling $6.6 billion in DOD’s main RDT&E
accounts and 56 adds totaling $2.0 billion in the RDT&E portion of the Defense Health
Program.11
In order for DOD to meet congressional intent in spending these funds, the enacted bill states that
“funding increases shall be competitively awarded, or provided to programs that have received
competitive awards in the past.”12 The exception to this rule is Community Project Funding,
which Congress “earmarks” for non-competitive award to particular universities. The enacted bill
includes $54.2 million in DOD RDT&E Community Project Funding.13
Selected Downward Adjustments
The enacted bill partly offsets the net effect of these and other upward adjustments on total
discretionary defense budget authority with $12.8 billion worth of downward adjustments relative
to the Administration’s request. The explanatory statement accompanying the enacted bill
explains legislators’ decisions about hundreds of these adjustments in terms of specific
reservations about particular programs.14

Department of Defense Appropriations Act, 2023: Overview and Selected Issues

The enacted bill cuts a total of $2.9 billion relative to the budget request for military personnel on
grounds that the armed forces would have fewer members in FY2023 than the request assumed.15
The explanatory statement ascribes these figures to “underexecution of strength.” While the
statement provides no further explanation, it has been widely reported that the Armed Forces –
particularly the Army – have been falling short of recruiting goals.16
Non-programmatic Line-Item Reductions
The enacted bill makes over 650 relatively small reductions to requested amounts in other
appropriations that add up to $9.9 billion.17 The explanatory statement accompanying the final
bill justifies each downward adjustment individually, often citing “unjustified growth” in the
Administration’s request for a given line item.18 Some of these “non-programmatic” reductions
are explained with reference to changes in a particular program’s anticipated performance
schedule.19 The enacted bill makes 44 reductions across 13 appropriation accounts on schedule
grounds (e.g., workload delays labeled “prior year carryover”) for a total of $857.6 million.20
Other enacted reductions are explained with brief labels such as “excess to need” or “historic
unobligated balances,” the latter phrase indicating that a particular program has exhibited a
consistent pattern over several years of reaching the end of its obligation authority with
significant unobligated balances.21
Rescissions and General Reductions
Apart from the downward adjustments already mentioned, the enacted bill also incorporates two
general reductions to budget authority in the overall appropriation:
• Section 8047 rescinds $1.1 billion in unspent funds appropriated by Congress in
prior fiscal years but not yet expired, returning those fund balances to the
Treasury and thereby offsetting some of the upward adjustments in the act from

18 In general, “unjustified growth” indicates the appropriators’ judgment that a requested funding increase in the budget
year was not sufficiently justified in the Administration’s budget justification exhibits. Based on CRS analysis, over
200 downward adjustments totaling $3.9 billion cite “unjustified growth” or “excess growth” in the enacted bill.
19 Non-programmatic adjustments are distinguished from programmatic adjustments that are applied formulaically
across appropriations, such as those reflecting pay raises, revised economic assumptions, and inflation adjustments.

21 The DOD FMR defines unobligated balances as “the cumulative amount of budget authority in an unexpired account
that is not obligated and that remains available for obligation under law.” DOD, Financial Management Regulation,
DOD 7000.14-R, Glossary, p. G-36. Unobligated balances in expired accounts generally cannot be placed on new
contracts, representing a failure to expend taxpayer dollars for congressionally mandated purposes during a specified
period of availability. Congress may therefore use “historic unobligated balances” to refer to programs that consistently
do not meet targeted spending rates established by DOD policy, increasing the risk of unobligated balances in expired
and cancelled accounts. See Defense Acquisition University, “OUSDC Rule-of-Thumb Acquisition Obligation and
Expenditure Rates,” at https://www.dau.edu/tools/Lists/DAUTools/Attachments/292/OSD%20(C)%20Color%20Rule-

for FY2023.22
• Section 8122 reduces the total appropriation by $956.4 million to account for
favorable exchange rates for U.S. dollars relative to foreign currencies.23
Budgetary Context
Based on the Administration’s FY2023 DOD budget request, defense outlays in FY2023 when
adjusted for inflation would exceed the department’s annual purchasing power during the Cold
War-era military buildup of the mid-1980s. However, the outlays would be lower than during the
peak years of post-9/11 military operations in Afghanistan and Iraq (see Figure 1).

8.7 “Outlays for Discretionary Programs: 1962-2027” and Table 8.8 “Outlays for Discretionary Programs in
Constant (FY2012) Dol ars: 1962-2027.”
Notes: Total DOD outlays include the relatively small proportion for military construction, which is funded in a
separate appropriations bil .
In general, the levels of discretionary outlays for defense and nondefense federal programs have
not been far apart since the aftermath of the 1991 war with Iraq. Defense spending ran slightly

information on how rescissions work, see Congressional Budget Office, “CBO explains how it estimates savings from
rescissions,” May 2023 at https://www.cbo.gov/publication/59209.
23 Congress authorizes DOD to maintain “foreign currency fluctuation” accounts to handle the effects of discrepancies
between expected costs and actual costs for transactions involving foreign currencies. These accounts accumulate
account balances (or “realized variance”) when exchange rates at the time of disbursement are more favorable to the
U.S. dollar than expected. See 10 U.S.C. §2779 and DOD, Financial Management Regulation, DOD 7000.14-R,
Glossary, pp. G-20, G-29. DOD submits to Congress a budget exhibit each year (Exhibit PB-18, “Foreign Currency
Exchange Data”) containing expectations for foreign currency exchange rates affecting certain budgeted line items. See
DOD, Financial Management Regulation, DOD 7000.14-R. Volume 2B, Ch. 19, p. 19-72.

higher during the peak of the Persian Gulf War while nondefense spending surged after 2019 in
response to the COVID-19 pandemic.
Combined discretionary defense and nondefense spending has been outstripped by mandatory
spending since the early 1990s. For FY2023, Office of Management and Budget (OMB)
projected mandatory outlays will total $3.7 trillion (of which Social Security, Medicare, and
Medicaid payments account for 75%), which would be more than double the discretionary outlays
total and nearly 4.7 times the discretionary defense amount (see Figure 2).

Budget Enforcement Act Category: 1962-2023”. Chart created by CRS.
Notes: Data for “National Defense” is for Budget Function 050, which includes a relatively small percentage of
spending that falls outside the scope of the annual defense appropriations bil , including funding for DOD military
construction and for defense-related spending by the Department of Energy and other agencies.
Selected Military Personnel Issues
The enacted bill provides $163.0 billion for Military Personnel (MILPERS) appropriations, which
is $1.2 billion (0.7%) less than the budget request. The enacted bill funds a total force, active and
reserve, numbering 2,087,344 uniformed personnel, which is 35,556 (1.7%) lower than the
FY2023 military end-strength in the budget request and 60,196 (2.8%) lower than the actual
FY2022 end-strength (see Table 4).
Unlike the end-strength totals in the enacted bill, neither H.R. 8236 nor S. 4663 assumed any
reduction in end-strength below the level assumed in the FY2023 budget request.24

24 Failure to meet end-strength goals during the fiscal year typically entails maintaining unobligated balances in one or
more MILPERS appropriations accounts. Since MILPERS funds have a one-year period of availability, these
unobligated balances tend to become candidates for transfer to other appropriations accounts through mid-year
reprogramming requests. These reprogramming requests require congressional notification and in practice can take
months to complete, increasing the risk that unused MILPERS funds may expire without being obligated. For more
information on transfer authority and reprogramming authority, see CRS In Focus IF11243, Defense Primer: DOD

Military Pay Raise
As requested, the enacted bill includes upwards of $3.0 billion to cover the cost of a 4.6%
increase in military basic pay which the Administration proposed to take effect on January 1,
Congressional Research Service

Department of Defense Appropriations Act, 2023: Overview and Selected Issues

2023.25 This adjustment matches the annual increase in the Employment Cost Index (ECI), a
Labor Department survey of wages and salaries in private industry.26
As noted above, in addition to the basic pay raise the enacted bill includes a total of $1.8 billion
for various allowances (food, housing, certain moving expenses, and basic needs of
servicemembers living below certain gross household income thresholds) to offset rising costs
due to inflation.
Extremist Ideologies
The explanatory statement associated with the enacted bill directs senior DOD officials to update
an earlier report to Congress on policies and actions taken to address the involvement of military
personnel with extremist or criminal groups.27
This language was adopted in lieu of language in the House committee report that would have
required DOD specifically to report on changes in security clearance policies, associated
procedures, and training to ensure that individuals who adhere to extremist ideologies are not
granted security clearances.28
Abortion Access
The enacted bill does not include a provision contained in the House-introduced bill (Section
8145) that would prohibit the denial of a request by any member of the armed forces or any DOD
civilian employee for leave for the purpose of obtaining an abortion or assisting a spouse, partner,
or significant other in obtaining an abortion.29
Sexual Assault, Prevention, and Response
The enacted bill fully funds DOD’s request for $479.0 million to implement the recommendations
of an Independent Review Commission (IRC) created in 2021 to provide an assessment of sexual
assault in the armed forces.30 These recommendations include creating a full-time sexual assault
prevention workforce, giving responders expanded support for dealing with caseloads, and
creating a dedicated research center.31
In addition, Section 8044 of the bill adds to the budget $47.0 million for the Sexual Assault
Special Victims’ Counsel Program.32

25 The direct cost of the proposed 4.6% increase in basic pay is $2.88 billion. It may generate additional increases
totaling several hundred million dollars in various fringe benefits that are linked by law to the basic pay rate.

Department of Defense Appropriations Act, 2023: Overview and Selected Issues

Defense Medical Facilities Reorganization
The enacted bill’s explanatory statement directs the Government Accountability Office (GAO) to
report on the status of the reorganization of DOD health care initiated by the FY2017 National
Defense Authorization Act (P.L. 114-328) and codified in Title 10, U.S. Code Sections 1073c and
1073d.33 DOD proposes to shift uniformed military medical personnel from certain medical
clinics and hospitals to major medical centers and combat-support units. Civilian medical
personnel are to fill some of the resulting vacancies while others go unfilled. Some military
dependents and retirees would be required to seek medical care from non-DOD facilities with
costs covered by DOD’s TRICARE program.
Selected Operation and Maintenance Issues
The enacted bill provides $278.1 billion in discretionary budget authority to Operation and
Maintenance appropriations, which is $6.8 billion (2.5%) more than the requested amount and
$21.8 billion (8.5%) more than the FY2022 enacted amount (in current dollars). The enacted bill
upwardly adjusts DOD’s FY2023 O&M budget request by billions of dollars in an effort to
improve the combat readiness of U.S. forces. These adjustments include:
• $1.5 billion for maintenance and repair of facilities;
• $485.0 million for equipment overhauls at specialized maintenance depots; and
• $427.0 million for recruiting and advertising costs.
The enacted bill also adds to the Navy’s budget request $322.0 million to pay for the continued
operation of several ships the Navy had planned to decommission. Section 8079 of the act
prohibits the Navy from decommissioning five Littoral Combat Ships included in this group.
Minimum Wage for Contractor Employees
The enacted bill does not include a provision from the House-introduced bill (Section 8024) that
would have required any for-profit contractor receiving funds appropriated by the act to pay any
employee at the rate of at least $15 per hour.
Removal of Confederate Names
The enacted bill adds to the request $1.0 million to continue the process of renaming DOD
installations and facilities currently named to commemorate the Confederate States of America or
any of its officials. A commission created to plan the renaming, mandated by Section 370 of the
William M. (Mac) Thornberry National Defense Authorization Act for FY 2021 (P.L. 116-283),
completed its mission in October 2022 with DOD implementation to follow not later than January
1, 2024.34

Department of Defense Appropriations Act, 2023: Overview and Selected Issues

Selected Environmental Issues
The enacted bill adds $520.7 million to the $1.1 billion requested for DOD’s Environmental
Restoration accounts, which fund the cleanup of hazardous waste and pollutants at military
installations and formerly used defense sites.
PFAS/PFOA Remediation
More than one-third of the added environmental restoration funds ($224.9 million) will expedite
cleanup efforts aimed at groundwater contamination by certain highly toxic chemicals that were
widely used as fire-fighting agents, particularly at aviation facilities.35 These chemicals, used in
products such as “aqueous film-forming foam,” are referred to as PFAS/PFOA. As of September
2022, DOD has identified 700 locations where it “is conducting or has completed an assessment
of PFAS use or potential release.”36
The House Appropriations Committee, in its report on H.R. 8236, acknowledges that no
commercially available PFAS replacement meets DOD safety standards.37 However, citing
“significant and salient public health risks” associated with PFAS/PFOA, the committee directs
DOD to comply with a provision of the FY2020 NDAA requiring that their use be phased out by
the start of FY2025 (P.L. 116-92, Section 322).38
Red Hill (Hawaii) Fuel Depot Cleanup
Section 8119 of the enacted bill provides $1.0 billion, as requested, to deal with the
contamination of a portion of Honolulu’s water supply by a fuel leak from the Navy’s Red Hill
bulk fuel depot by removing all fuel from the facility and closing it.39 The facility, opened in
1943, includes 20 large tanks – with a total capacity of 250 million gallons of ship and aircraft
fuel – buried in a hillside overlooking Pearl Harbor and above a major aquifer.40
In 2014, a leak of 27,000 gallons of jet fuel highlighted the risk of water contamination from the
facility. Subsequent inadvertent fuel release and ensuing legal efforts culminated in DOD’s
decision early in 2022 to close the facility and move elsewhere the fuel it still contained.41

Department of Defense Appropriations Act, 2023: Overview and Selected Issues

Selected War on Terror Issues
Section 8142 of the enacted bill prohibits the use of appropriated funds to close the detention
facility at Guantanamo Bay, Cuba. Section 8139 of H.R. 8236 included a provision that would
have mandated closure of the facility.
The enacted bill also includes provisions barring the use of funds to transfer certain detainees
from Guantanamo Bay to U.S. territory (Section 8139); to transfer any Guantanamo Bay detainee
to any foreign country (Section 8140); or to construct any facilities in the United States to house
any Guantanamo Bay detainees (Section 8141).
Use of Force Authorizations
The enacted bill does not include any provision affecting legislation adopted in 2001 and 2002
authorizing U.S. military operations in the wake of the September 11, 2001 terrorist attacks on the
United States. H.R. 8236 would have repealed both of those measures:
• Section 8148 would have repealed P.L. 107-40, the joint resolution adopted in
2001 to authorize the use of military force against perpetrators of the September
11, 2001 attacks; and
• Section 8149 would have repealed P.L. 107-243, the joint resolution adopted in
2002 to authorize the use of military force against Iraq
Selected Acquisition Issues
The enacted bill provides $162.2 billion in new discretionary budget authority for DOD
Procurement programs, $17.2 billion (11.9%) above the requested level and $17.3 billion (11.9%)
above the FY2022 enacted level (in current dollars).
For DOD Research, Development, Test, and Evaluation (RDT&E) programs, the enacted bill
provides $139.8 billion in new discretionary budget authority, $9.9 billion (7.6%) above the
requested level and $20.5 billion (17.2%) above the FY2022 enacted level (in current dollars).
Expedited Acquisition Process
In the explanatory statement accompanying the act, House and Senate negotiators assert that
DOD has hampered congressional oversight of certain weapons acquisition programs by
excessive use of streamlined procedures intended to speed up the fielding of new technologies,
bypassing some reporting requirements and other checks built into the routine procurement
process.42
At issue is a so-called “middle-tier of acquisition” created by a provision of the FY2016 NDAA
(P.L. 114-92, Section 804). Some acquisition reform proponents had contended that the
development and deployment of weapons based on promising new technologies was being unduly
delayed by the detailed advance planning and testing required by DOD’s standard procedures. In

response, the so-called “Section 804” criteria allowed DOD to bypass some of those procedures
in two types of cases:
• Rapid Prototyping, in which innovative technologies would be used to field
prototypes of operational equipment within 5 years; and
• Rapid Fielding, in which proven technology would be used to begin production
of new equipment within 6 months and to field a full production run in 5 years.
The explanatory statement objects that congressional oversight of rapid prototyping and fielding
programs since passage of P.L. 114-92 has been hampered by the lack of some of the
documentation dispensed with in the name of streamlining, such as independent cost estimates,
technology assessments, and test plans. The statement also expresses concern that the armed
services are equipping forces with items justified in budget documentation as RDT&E programs,
thus obscuring the total cost of certain programs and prematurely eliminating possible
alternatives.43
Section 8059 of the act generally prohibits the use of RDT&E funds to buy equipment for
operational use and requires DOD to submit with the FY2024 budget request a detailed report on
the planned use of RDT&E funds for testing purposes.44
Strategic Nuclear Forces
With relatively few changes, the act funds the Administration’s program for across-the-board
modernization of the U.S. “triad” of long-range nuclear weapons systems. The act funds to
continue developing the B-21 Raider bomber; a new intercontinental ballistic missile (ICBM)
designated the Ground-Based Strategic Deterrent or Sentinel; the Columbia-class ballistic missile
submarine; and production funds for the bomber and submarine. The act also provides, as
requested, the first year of procurement funding for the Long-Range Stand-Off (LRSO) missile,
intended to replace the 1970s-vintage air-launched cruise missile carried by U.S. bombers (see
Table 5).
The total of $5.9 billion the act provides, as requested, for Columbia-class missile submarine
procurement includes a $3.1 billion share of the projected $15.2 billion cost of the first of the
planned class of 12 submarines.45 The remaining $2.8 billion is to buy components or pay for
other work in preparation for construction of the other 11 planned subs.
Sea-Launched Cruise Missile
The act adds to the DOD budget request $45.0 million to continue development of a nuclear-
armed, sea-launched cruise missile (SLCM-N). The FY2022 budget included $15.2 million to
develop the weapon, but it was not included in the FY2023 budget by the Biden Administration.46

43 Ibid.
44 The section permits the Secretary of Defense to waive this restriction on a case-by-case basis by providing certain
written justification to the congressional appropriations committees. See Ibid., p. 471, clause (c).
45 The $15.18 billion total includes $6.56 billion for complete planning and detailed design of ships of the projected
class. The Navy typically includes such costs in its budget for the first ship of a new class. The projected total cost of
building the first Columbia-class ship is $8.62 billion. For additional background, see CRS Report R41129, Navy
Columbia (SSBN-826) Class Ballistic Missile Submarine Program: Background and Issues for Congress, by Ronald

Precision Strike Weapons
The act generally supports the requests by the Army, Navy, and Air Force for funds to develop
and begin fielding various non-nuclear armed, precision-strike missiles. These include ballistic
missiles that travel on a parabolic trajectory, cruise missiles that can maneuver during flight, and

hypersonic weapons which – like many ballistic missiles – travel at speeds of at least five times
the speed of sound (Mach 5 or more than 3,800 mph) but additionally are capable of maneuvering
throughout their course of flight.47
Hypersonic weapons include both rocket-launched glide vehicles and cruise missiles powered by
air-breathing jets (see Table 6).

Anti-Missile Defenses
In general, the act supports the DOD funding request to continue fielding anti-missile defenses
both for U.S. territory and for U.S. forces and allies abroad (see Table 7). This includes support
for priorities described by Missile Defense Agency Director Vice Admiral Jon Hill as his top
three: homeland defense, defense of Guam, and defenses against hypersonic missiles.48
Selected Homeland Defense Programs
The act provides $785.4 million to fund continued upgrades to the ground-based mid-course
ballistic missile defense system currently fielded to defend U.S. territory against intercontinental
ballistic missile attacks, enabling an operational fleet of 44 ground-based interceptor missiles
deployed in Alaska and California.49 This includes, in addition to the amount requested, $33.2
million to extend the operational life of currently-deployed interceptors.
The act also provides the funds requested for two initiatives intended to enhance homeland
missile defense systems:
• $1.8 billion for development of a new, “Next Generation Interceptor” (NGI) to
enable an increase in total deployed interceptor missiles from 44 to 64;50 and
• $75.1 million to field in central Alaska a new “Long-Range Discrimination
Radar” intended to be more capable than current radars in distinguishing between
incoming missile warheads and decoys.51
Defense of Guam
The enacted bill includes a total of $419.7 million –$4.7 million less than the amount requested –
for two budget lines to fund development and deployment of a missile defense network on Guam

that could protect the island against attack from any quarter.52 The system would integrate four
radars, a land-based version of the Navy’s Aegis system, and other Army and Navy equipment to
deal with ballistic, hypersonic, and cruise missile threats.
Defense Against Hypersonic Missiles
The act provides $518.0 million, more than double the $225.5 million requested, to develop
defenses against hypersonic missiles.53 Compared with ballistic missiles, hypersonic weapons
pose a more complicated threat because they travel at much lower altitudes and are more
maneuverable.54
As requested, the act also provides $89.2 million to continue developing a network of missile
tracking satellites designated the Hypersonic and Ballistic Tracking Space Sensor (HBTSS).55
Compared with existing ballistic missile tracking systems, HBTSS is intended to locate a target
more precisely and transmit that information more quickly to the weapons intended to intercept
the target.56

Consolidated Appropriations Act, 2023.
DOD Space Programs
In its report to accompany H.R. 8236, the House Appropriations Committee questioned the long-
term realism of the budget request for the U.S. Space Force, created by the FY2020 NDAA as a
separate armed service within the Department of the Air Force:57
[T]he Space Force’s ambitious plans ...do not appear to be backed up with credible budget
projections in the outyears to actually deliver these capabilities....The lack of a credible
five-year budget raises fundamental questions about whether any serious analysis or long-
term planning has been done to assess the realism and affordability of the entire
portfolio....[T]he Space Force’s plans and programs must be based on rigorous technical
analysis matched with executable plans resourced by realistic budgets. The current plan
does not meet this expectation....
The committee directed the Air Force to provide a detailed briefing on the costs, affordability,
executability, and risks of current and planned Space Force programs (see Table 8).58
Missile Tracking Satellite Networks
The enacted bill provides a slight increase over the $4.7 billion requested to continue developing
two new networks of ballistic missile tracking satellites to replace the Space-Based Infra-Red
System (SBIRS) satellites currently in orbit. Whereas SBIRS relies on a relatively small number
of relatively large and complex satellites, the planned replacement systems would rely on a larger

number of smaller satellites, thus complicating any adversary’s attempt to neutralize the system
by taking out a small number of the satellites.59
To continue development of the Next-Generation Overhead Persistent Infra-Red (OPIR) system,
slated to begin supplanting SBIRS in 2025, the enacted bill provides $3.4 billion of the $3.5
billion requested.
To continue development of the Resilient Missile Warning Tracking System that will comprise
several dozen relatively small satellites in orbits lower than SBIRS, the enacted bill provides $1.2
billion, an increase of $142.8 million over the request.

Note: “FY2023 Requested” and “Enacted Bil Division C” amounts reference, where possible, DOD’s Program
Acquisition Cost by Weapon System (PACWS) reports for FY2023 and FY2024. These reports aggregate budget
requests and prior year enacted amounts across all RDT&E and Procurement Program Elements, Projects, and
sub-Project efforts. Amounts for House and Senate columns reference reports that are limited to line item level
detail. As a result, in some cases amounts in the House and Senate columns may not capture certain sub-Project
efforts present in PACWS tables but located in line items predominantly associated with a different weapon
system or activity. In limited cases, PACWS may include enacted values from other divisions of the act. For
weapon systems not individually listed in PACWS, “Enacted Division C” amounts reflect CRS analysis of the
explanatory statement accompanying the Consolidated Appropriations Act, 2023.
Ground Systems
In general, the enacted bill supports ongoing Army and Marine Corps programs to modernize the
services’ suite of armored combat vehicles and to field systems designed to deal with unmanned
aerial vehicles (UAVs) and other aerial threats. Tracking H.R. 8236, the enacted bill adds $187.1
million to the $493.0 million requested to accelerate modernization of the Army’s Paladin self-
propelled artillery. Like S. 4663, it nearly doubles the amount requested to upgrade M-1 Abrams
tanks, adding $591.0 million to the $656.3 million request, procuring an additional 46 vehicles
(see Table 9).
IVAS Night Vision System
The enacted bill provides $40 million of the $400.0 million requested to purchase thousands of
wearable night-vision goggles on which troops could see targeting cross-hairs and navigation
information, as on the heads-up display (HUD) in a fighter plane’s cockpit. In March 2021, the
Army contracted with Microsoft to spend up to $21.9 billion over 10 years to procure this
Integrated Visual Augmentation System (IVAS), based on the firm’s HoloLens augmented reality
goggles.60 As it had done with the Army’s FY2022 IVAS budget request, Congress justified its
action on the FY2023 request by citing various hardware and software problems with IVAS that
surfaced in the course of tests by DOD’s independent operational testing office.
On January 6, 2023, the Army announced that Microsoft was going to further modify the device
to better adapt it for use in a combat environment.61

requests and prior year enacted amounts across all RDT&E and Procurement Program Elements, Projects, and
sub-Project efforts. Amounts for House and Senate columns reference reports that are limited to line item level
detail. As a result, in some cases amounts in the House and Senate columns may not capture certain sub-Project
efforts present in PACWS tables but located in line items predominantly associated with a different weapon
system or activity. For Guided MLRS rockets and launchers, the FY2024 PACWS enacted value for FY2023 is
$1,319.6 mil ion, indicating $527.0 mil ion of GMLRS procurement is appropriated in another division of the act.
For weapon systems not individually listed in PACWS, “Enacted Division C” amounts reflect CRS analysis of the
explanatory statement accompanying the Consolidated Appropriations Act, 2023.

Shipbuilding Programs
The enacted bill adds a total of $4.0 billion to the Navy’s $27.9 billion shipbuilding request, for
an enacted total of $32.0 billion. The upward adjustments include:
• $2.2 billion for a third destroyer equipped with the Aegis anti-aircraft/anti-missile
defense system in addition to the two ships included in the budget request;62 and
• $645.0 million for two high-speed troop transports modified to serve as hospital
ships63
Also added is a total of $803.164 million for ships that could support Marine Corps expeditionary
landings:
• $289.0 million for components to be used in an additional helicopter carrier;
• $250.0 million for components to be used in an LPD-type amphibious landing
transport; and
• $264.1 million for three of the large hovercraft the Marines use to haul missile
launchers and other heavy equipment ashore from transport ships (see Table 10).
Proposed Ship Retirements
The DOD budget request assumed some cost reductions as the result of retiring 24 Navy ships,
including nine Freedom-class Littoral Combat Ships (LCS), four of which had been
commissioned in 2019 and 2020. The LCS program has been controversial over the years due to
past cost growth, design and construction issues, concerns over their ability to withstand battle
damage, and concerns over the development and testing of modular mission packages.65 Section
8079 of the enacted bill prohibits the use of funds to decommission five of the LCS ships as
planned.

reflect CRS analysis of the explanatory statement accompanying the Consolidated Appropriations Act, 2023.
Aircraft Programs
The enacted bill generally funds the request for DOD aircraft with some relatively significant
upward adjustments. Among amounts added to the budget request are:
• $0.9 billion for 16 F-35 fighters, in addition to the $8.9 billion requested for
procurement of 61 of the aircraft, different versions of which are used by the
Navy, Marine Corps, and Air Force;66
• $600 million for eight Navy F/A-18s, which is to sustain a production line DOD
had planned to shut down;
• $273 million for 10 Blackhawk troop-carrying helicopters for the Army National
Guard, in addition to the $650.4 million requested for 25 new Blackhawks (see
Table 11).67
AWACS Replacement
The enacted bill provides $426.8 million – $187.1 million more than was requested – to continue
development work on a replacement for the 1980s-vintage E-3 Airborne Warning and Control
System (AWACS) aircraft. The E-3, based on the Boeing 707 jetliner, scans the surrounding
airspace with a rotating, saucer-shaped radar antenna 30-feet-wide.
The planned replacement, designated the E-7, is a modified Boeing 737. It carries a blade-like
radar antenna, about 10-feet high, which runs along the top of the aircraft and which scans
electronically, rather than by mechanical rotation. The Royal Australian Air Force has operated
this type, nicknamed “Wedgetail,” since 2015.
Combat Rescue Helicopter
The enacted bill provides $1.21 billion for 20 Combat Rescue Helicopters, an increase of $499
million and 10 aircraft over the budget request. This version of the Blackhawk helicopter
(designated HH-60W) is equipped with additional fuel tanks and other modifications to support
the mission of retrieving downed pilots and other personnel who might be behind enemy lines.

Department of Defense Appropriations Act, 2023: Overview and Selected Issues

Appendix.
Tables 3-9 of this report summarize the amounts requested by the Biden Administration,
recommended by the House and Senate, and agreed to in the enacted version for procurement
and/or research and development (R&D) regarding selected weapons programs in each of several
broad categories, e.g., missile defense, ground combat. The funding data for these selected
programs is drawn from 17 procurement appropriation accounts and five R&D accounts that are
components of the DOD budget. Each of those accounts is further subdivided into “line items”—
dozens of them in some procurement accounts, and hundreds of them in most of the R&D
accounts.
The official DOD labels of some line items may not correspond to the names that commonly are
used to refer to programs in the course of congressional deliberations. Moreover, funding for a
single program may be spread across several line items. In addition, R&D funding for a particular
program may be only one of several projects funded by a single line item.
Selection of the budget lines to be included in the totals for any program listed in any of the
Tables is based on CRS analysis. For further information concerning any specific instance,
congressional staff may consult relevant CRS products listed in the tables or any of the following
CRS analysts.
