U.S. Army Long-Range Precision Fires: 
March 16, 2021 
Background and Issues for Congress 
Andrew Feickert 
Improvements to potential adversaries’ artillery systems present a challenge to the U.S. military, 
Specialist in Military 
the Army in particular. In addition to the challenge of improved artillery system capabilities and 
Ground Forces 
new employment techniques, the proliferation of special munitions—such as precision, 
  
thermobaric, and top-attack munitions—has renewed concerns about the potential impact of 
enemy cannon and rocket artillery on U.S. combat operations and ground combat systems. 
 
In response to this challenge, the U.S. Army is seeking to improve its ability to deliver what it refers to as long-range 
precision fires (LRPF) by upgrading current artillery and missile systems , developing new longer-range cannons and 
hypersonic weapons, and modifying existing air- and sea-launched missiles and cruise missiles for ground launch by Army 
units. 
Both the 2018 National Defense Strategy and the Army’s Multi-Domain Operations operational concept call for improved 
Army LRPF capability to counter what has been described as Russian and Chinese anti-access, area denial (A2/AD) 
strategies designed to limit the freedom of movement and action of U.S. forces in both Europe and the Pacific region.  
The Army has five major programs or efforts underway or under consideration to improve long-range precision fires 
capabilities: 
  
The Extended  Range Cannon Artillery (ERCA) program plans to develop a system capable of 
accurately firing at targets more than 70 kilometers away, an improvement over the 30-kilometer target 
distance of current systems. 
  
The Precision Strike Missile (PrSM) is a surface-to-surface, all weather, precision-strike guided missile 
fired from the M270A1 Multiple Launch Rocket System (MLRS) and the M142 High Mobility Artillery 
Rocket System (HIMARS). PrSM is intended to replace current MLRS and HIMARS missiles and doubles 
the current rate-of-fire, with two missiles per launch pod. 
  The Army is examining the feasibility of developing a 
Strategic Long-Range Cannon (SLRC) that can 
fire a projectile at hypersonic speeds up to 1,000 miles to engage air defense, artillery, and missile systems 
and command and control targets.  
  The Army, Navy, Air Force, and Missile Defense Agency (MDA) are developing a 
Common- Hypersonic 
Glide Body (C-HGB),  which the Army plans to use as part of its Long-Range Hypersonic Weapon 
(LRHW) program, enabling the C-HGB to be launched from mobile Army ground missile launchers. 
  Finally, the Army is attempting to modify existing 
Navy SM-6 and 
UGM-109 Land  Attack Missiles for 
ground launch to provide the Army with a mid-range missile capability. 
In its oversight, authorization, and appropriations roles, Congress might further study the Army’s LRPF program, given 
potential resource constraints and the importance the Army places on LRPF. Potential issues for Congress include 
  justification for strategic cannons, hypersonics, and mid-range battlefield missiles;  
  estimated LRPF total costs; 
  LRPF and the U.S. Indo-Pacific Command’s Investment Plan for the Pacific Deterrence Initiative (PDI); 
  force structure requirements;  
  LRPF in the Reserve Components; 
  other Services’ views on Army LRPF; and 
  commanding and controlling and targeting long-range fires.

U.S. Army Long-Range Precision Fires: Background and Issues for Congress  
 
Why Is This Issue Important to Congress? 
Article I, Section 8, of the Constitution gives Congress the authority to “raise and support 
Armies.” On an annual basis, Congress authorizes and appropriates funds for the Army to, among 
other things, modernize its fleet of ground combat systems. As part of this process, congressional 
defense committees annual y hold dedicated hearings on the Army’s budget request for the 
upcoming fiscal year and a hearing specifical y on Army modernization. Congressional defense 
committees also, on occasion, hold hearings on specific Army ground combat systems. 
According to the Army’s 2019 Modernization Strategy and statements by Army leadership, long-
range precision fires (LRPF) is the Army’s primary modernization priority.1 The Army anticipates 
that its “budget wil  remain flat, resulting in reduced spending power over time.”2 Suggestions 
that the Biden Administration’s FY2022 defense budget request might be “flat,” along with the 
potential  results of the recently announced FY2022 defense budget review3 could have 
implications for the Army’s LRPF modernization plans. In its oversight, authorization, and 
appropriations roles, Congress might further study the Army’s LRPF program, given potential 
resource constraints and the importance the Army places on LRPF. 
Background 
Perceived Need for Army Long-Range Precision Fires 
While the Army has a variety of means to deliver long-range fires, such as organic attack 
helicopters and unmanned aerial vehicles (UAVs) and air support from Navy and Air Force 
aircraft, these assets are frequently unavailable due to adverse weather and terrain as wel  as 
availability.  U.S. Army cannon artil ery and missile and rocket systems, on the other hand, 
general y do not suffer from these restrictions and are part of Army formations from the brigade 
to corps level.  
From a threat perspective, the proliferation of special munitions (e.g., precision, thermobaric, and 
top-attack munitions), along with improving artil ery system capabilities and new employment 
techniques, have renewed concerns about the potential impact of enemy cannon and rocket 
artil ery on U.S. combat operations and ground combat systems. One senior U.S. Army official 
contends, “Russia possesses a variety of rocket, missile, and cannon artil ery systems that 
outrange and are more lethal than U.S. Army artil ery systems and munitions.”4 Operational y, 
one study noted that: 
Russian artillery, particularly rocket launchers with conventional, thermobaric, and cluster 
munitions—using unmanned aerial systems (UAS), both for  target location and battle

damage assessment—is particularly effective against Ukrainian light armor and infantry 
formations.5 
In a similar manner, China is reportedly upgrading both its cannon and rocket artil ery. Another 
study noted: 
The entrance of the Chinese and their greater emphasis o n much heavier, longer-range 
rockets that begin to bridge the gap between  rocket  artillery and short-range ballistic 
missiles could have a significant effect over time in extending the trend toward longer-
range strike systems.6 
Compared with potential adversaries’ longer-range systems, wider variety of munitions, and 
innovative target acquisition techniques, a diminished U.S. artil ery capability—based on fewer 
units, limitations on cluster munitions use, and shorter effective ranges—could present significant 
battlefield chal enges for the U.S. Army, with implications for modernization efforts.  
Long-Range Precision Fires and the National Defense Strategy 
(NDS) and Multi-Domain Operations (MDO) 
The Army’s perceived need to improve the range and precision of its current artil ery systems is 
viewed by many observers to justify, to a degree, developmental and modernization efforts. These 
undertakings are considered to play a crucial role in supporting the U.S. National Defense 
Strategy. Proposed improvements to the Army’s artil ery capabilities  should support how the 
Army and the Joint Force intends to fight. 
National Defense Strategy 
In 2018, the Commission on the National Defense Strategy for the United States published its 
congressional y-mandated (P.L. 114-328, §942) “independent, nonpartisan review of the 2018 
National Defense Strategy (NDS) and issues of U.S. defense strategy and policy more broadly.”7 
Among their many recommendations, the Commission stated: 
Of  the five competitors and adversaries named in the NDS, four—China, North Korea, 
Russia, and terrorist groups—are active in the Indo-Pacific region. Deterring aggression in 
this region requires establishing a forward-deployed defense-in-depth posture. Protecting 
U.S. interests from China and Russia will require additional investment in the submarine 
fleet; intelligence, surveillance, and reconnaissance (ISR) assets; air defense; long-range 
strike platforms; and 
long-range ground-based fires [emphasis added].8 
Specifical y related to the Army, the Commission recommended: 
The United States will need capacity enhancements in the Army. More armor, 
long-range 
fires [emphasis added], engineering, and air-defense units are required to meet the ground-

heavy challenges  posed by Russia in  Eastern Europe and while  maintaining a  robust 
deterrent to aggression on the Korean Peninsula.9 
In addition to acknowledging the importance of long-range precision fires in U.S. defense 
strategy, the Commission’s recommendations seem to support Army requirements regarding the 
need to significantly upgrade the Army’s long-range precision fires capability. 
Multi-Domain Operations10 
In December 2018, the Army introduced its Multi-Domain Operations (MDO) operational 
concept. According to the Army, MDO was developed in response to the 2018 National Defense 
Strategy, which shifted the previous focus of U.S. national security from countering violent 
extremists worldwide to confronting revisionist powers—primarily Russia and China. The MDO 
concept is to prevail by competing successfully in al  domains, short of conflict, to deter a 
potential enemy. If deterrence fails, Army forces—along with the Joint Force—are to 
  
penetrate enemy anti-access and area denial systems (layered and integrated 
long-range precision-strike systems, littoral anti-ship capabilities, air defenses, 
and long-range artil ery and rocket systems) to enable strategic and operational 
maneuver of U.S. forces; 
  
disintegrate—disrupt, degrade, or destroy enemy anti-access and area denial 
systems to enable operational and tactical maneuver of U.S. forces; 
  
exploit the resulting freedom of maneuver
 to achieve operational and strategic 
objectives by defeating enemy forces in al  domains; and 
  
recompete—consolidate gains across domains and force a return to competition 
on favorable terms to the United States and al ies. 
According to the Army, successfully prosecuting an MDO requires longer-ranged, precision 
artil ery systems that can counter enemy long-range precision-strike systems and penetrate and 
disintegrate enemy defenses. MDO is to be a central feature of the new Joint Warfighting Concept 
featuring Al   Domain Operations—“next-generation, information-based wars using enormous 
amounts of fast computer analysis across the land, air, sea, space and cyberspace domains.”11 The 
Department of Defense (DOD) anticipates the new Joint Warfighting Concept wil  be published 
and adopted sometime in 2021.12 
Post-Cold War History of Army Artillery 
During the Cold War, a robust U.S. Army artil ery capability was seen as a means of countering 
numerical y superior armored and mechanized forces of the Soviet Union and Warsaw Pact.13 
During the Cold War years, Army artil ery units consisted of 105 mm, 155 mm, and 8-inch 
cannon artil ery, including both self-propel ed and towed variants. Both 155 mm and 8-inch

cannon artil ery systems could fire nuclear projectiles and conventional shel s. The Army also had 
two nuclear-capable tactical bal istic missiles: the Lance, with a range of about 75 miles, and the 
two-stage Pershing, with a range of about 460 miles. In 1982, the Army fielded the Multiple 
Launch Rocket System (MLRS), which could fire rockets with high-explosive and cluster 
munitions14 warheads out to a range of 165 miles.  
With the end of the Cold War in 1991, the George H.W. Bush Administration  and later the Clinton 
Administration  sought to reduce U.S. military forces in response to perceived decreases in the 
threat to U.S. security interests and a desire to use savings from reduced defense budgets as a 
“Peace Dividend” to fund other nonmilitary governmental needs.15 
According to the Congressional Budget Office (CBO), in January 1992, the Clinton 
Administration submitted a plan to significantly reduce the number of military forces, particularly 
those in the Army and the tactical Air Force.16 For example, between 1990 and 1997, the number 
of Active and Reserve divisions in the Army were to be reduced by 10 divisions, including 6 
divisions from the Active forces and 4 from the Reserves.17 
As part of Amy force reductions, the number of field artil ery units decreased significantly. 
According to the Army Center of Military History: 
A total of 218 field artillery battalions (96 Regular Army, 17 Army Reserve, and 105 Army 
National Guard) and 38 batteries, including the batteries in armored cavalry regiments (27 
Regular Army and 11  Army National Guard), existed in 1989  prior to the Persian Gulf 
War. By 1999, only 141 battalions (50 Regular Army and 91 Army National Guard) and 
22  batteries (12 Regular Army and 10 Army National Guard) remained. Army Reserve 
field  artillery  was reduced by 100  percent as a  result of  the “bottom-up” review by 
Secretary of Defense Les Aspin in 1993, which in fact eliminated all Army  Reserve combat 
arms units, allowing that component to focus on support and service organizations.18 
Attempts to Modernize Army Combat Systems19 
The U.S. Army’s current fleet of tanks, tracked infantry fighting vehicles, self-propel ed (SP) 
artil ery, and multiple launch rocket systems—the nucleus of the Army’s armored ground 
forces—was developed in the 1970s and fielded in the 1980s to counter the Soviet Union’s and 
Warsaw Pact’s numerical y superior ground forces. The combat performance of these systems 
against Iraqi forces Operation Desert Storm in 1991 reaffirmed for many the role these systems 
would play in future Army ground operations.

Efforts to modernize these systems was not as successful as was their performance in Desert 
Storm. In 2002, the Secretary of Defense cancel ed the $11 bil ion  Crusader self-propel ed 
artil ery system, largely due to its excessive weight and cost. In 2009, the Secretary of Defense 
cancel ed the $160 bil ion  Future Combat System (FCS) program, intended to develop 
replacements for the M-1 Abrams tank, the M-2 Bradley IFV, and the M-109A6 Paladin artil ery 
system, due to unrealistic technology expectations and cost. Under the FCS program, the Non-
Line-of-Sight-Cannon (NLOS-C) was to have replaced the M-109A6; this program was cancel ed 
when the FCS program was terminated in 2009. One defense expert reportedly suggested, “The 
FCS program was such a massive failure and a missed opportunity for Army modernization. I 
think this program single-handedly set the Army back a generation in vehicle technology.”20 
International Agreements Governing Munitions and Battlefield 
Missile Range 
Current U.S. artil ery systems, as wel  as future modernization plans (including LRPF efforts), are 
governed by two primary international agreements. These agreements are discussed briefly: 
United Nations (UN) Convention on Cluster Munitions (CCM)21 
According to the UN: 
The Convention on Cluster Munitions (CCM) prohibits under any circumstances the use, 
development, production, acquisition, stockpiling and transfer of cluster munitions, as wel  
as the assistance or encouragement of anyone to engage in prohibited activities. A cluster 
munition is a weapon consisting of a container or dispenser from which many submunitions 
or bomblets are scattered over wide areas. Many submunitions are unreliable and fail to 
explode, thus creating a potential humanitarian impact on civilians both during as wel  as  
long after  the conflict  ends.  The Convention  provides a comprehensive international 
response to the suffering caused by the use of cluster munitions and their remnants, to 
prevent the proliferation and future use of these weapons.  
The Convention was opened for signature in Oslo on 3 December 2008 and entered into 
force on 1 August 2010.22 
The United States, Russia, China, Israel, Egypt, India, and Pakistan did not participate in the 
CCM talks, nor did they sign the agreement. Despite not signing the agreement, the United States 
and DOD decided to undertake efforts to reduce the failure rate of cluster munitions to 1% or less 
to comply with the spirit of the Convention. DOD issued policy directives in 2008 and 2017 
requiring, without exception, that cluster munitions used after 2018 must leave 1% or less of 
unexploded submunitions on the battlefield.23  
DOD’s 2017 revised policy reversed the 2008 policy requirement regarding cluster munitions. 
The revised policy permits combatant commanders to use cluster munitions that do not meet the

1% or less unexploded submunitions standard in extreme situations to meet immediate 
warfighting demands. Furthermore, the 2017 policy does not establish a deadline to replace 
cluster munitions exceeding the 1% rate; these munitions are be removed only after new 
munitions that meet the 1% or less unexploded submunitions standard are fielded in sufficient 
quantities to meet combatant commander requirements. However, the policy stipulates that DOD 
“wil  only procure cluster munitions containing submunitions or submunition warheads” meeting 
the 2008 unexploded ordnance (UXO) requirement or possessing “advanced features to minimize 
the risks posed by unexploded submunitions.”24 
In December 2008, the Army decided to cease procurement of a Guided Multiple Launch Rocket 
System (GMLRS) warhead—the Dual-Purpose Improved Conventional Munition (DPICM) 
warhead—because its submunitions had a dud rate up to 5%.25 As efforts to reduce submunition 
failure rates to 1% or less have proven difficult to achieve, newer munitions being developed for 
cannons and missiles have instead focused on unitary warheads. 
Intermediate-Range Nuclear Forces (INF) Treaty26 
From 1987 to 2019, the United States and Russia were signatories to the INF Treaty, w hich 
required both countries to eliminate and reduce nuclear and ground-launched missiles according 
to their range. In 2019, following U.S. al egations that Russia had violated its treaty obligations, 
the United States withdrew from the treaty. According to the Arms Control Association: 
The 1987 Intermediate-Range Nuclear Forces (INF) Treaty required the United States and 
the  Soviet  Union  to  eliminate  and  permanently  forswear all  of  their  nuclear  and 
conventional ground-launched ballistic and cruise missiles with ranges of 500  to 5,500 
kilometers. The treaty marked the first time the superpowers had agreed to reduce their 
nuclear arsenals, eliminate an entire category of nuclear weapons, and employ extensive 
on-site inspections for verification. As a result of the INF Treaty, the United States and the 
Soviet Union destroyed a total of 2,692  short-, medium-, and intermediate-range missiles 
by the treaty’s implementation deadline of June 1, 1991.27 
With respect to al eged Russian violations and U.S. withdrawal from the treaty, the Arms Control 
Association also noted: 
The United States first alleged in its July 2014  Compliance Report that Russia was in 
violation of its INF Treaty obligations “not to possess, produce, or flight-test” a ground-
launched cruise missile having a range of 500 to 5,500 kilometers or “to possess or produce 
launchers of such missiles.” Subsequent State Department assessments  in  2015,  2016, 
2017,  and 2018 repeated these allegations. In March 2017, a top U.S. official confirmed 
press reports that Russia had begun deploying the noncompliant missile. Russia has denied 
that it  is  in violation of  the agreement and has accused the United States of being in 
noncompliance.

On February 2, 2019  the Trump administration declared a suspension of U.S. obligations 
under the INF Treaty and formally announced its intention to withdraw from the treaty in 
six  months. Shortly thereafter, Russian President Vladimir  Putin  also announced that 
Russia will be officially suspending its treaty obligations as well.  
On Aug. 2, 2019, the United States formally withdrew from the INF Treaty.28 
While the INF Treaty was in force, U.S. Army missiles were limited to a range of 499 kilometers. 
However, after the United States withdrew from the treaty in 2019, this range limitation no longer 
applied. As a result, the Army is now seemingly permitted to develop and procure both ground-
launched bal istic and cruise missiles with a range in excess of 500 kilometers.

Current Artillery Systems in Combat  
The Army has a variety of cannon artil ery systems in use with the Active and Reserve 
components. A 2019 RAND Report summarizes these systems and associated units: 
Cannon Systems 
Howitzer [cannon] systems, whether towed or self-propelled, are the primary brigade-level 
fire  support units in the Army. Compared with mortars, howitzers are much larger and

heavier and fire larger projectiles at greater distances, but at lower rates of fire The 155mm 
cannons in the Army’s inventory are also capable of firing the M982 “Excalibur” Global 
Positioning System (GPS)-guided projectile, which has a maximum range of almost 40 km 
when fired from a 39-caliber gun (both the towed and self-propelled 155mm howitzers in 
service in the Army have 39-caliber barrels). There is also an older precision round, the 
M712 “Copperhead,” which is laser-guided, though it has more limited range (16 km). Of 
additional note, the Army has also funded the M1156 Precision Guidance Kit (PGK) fuze 
for full-rate production as of 2016; this will provide a much more cost-effective precision 
capability as it leverages existing ammunition, although these will not have the extended 
range of Excalibur. 
Each Brigade Combat Team (BCT) has an organic field artillery battalion equipped with 
18 howitzers, organized in three batteries of six guns each: 
• The Infantry Brigade Combat Team’s (IBCT’s ) field artillery battalion has two batteries 
of M119 105mm  howitzers
 [Figure 1] and one battery of M777 155mm howitzers 
 [Figure 
2]; 
• The Stryker Brigade Combat Team’s (SBCT’s) field artillery battalion has three batteries 
of M777 155mm  howitzers; and 
•  The  Armored Brigade Combat  Team’s  (ABCT’s) field  artillery  battalion has three 
batteries of M109A6 Paladin self-propelled howitzers. 
Only the IBCT still fields 105mm howitzers; although they are less capable, they are much 
lighter than 155s and may be towed by a High-Mobility Multipurpose Wheeled Vehicle 
(HMMWV). The IBCT’s single battery of 155mm  howitzers gives it an extended-range 
precision capability, albeit in limited numbers. 
The Army’s sole remaining self-propelled howitzer is the M109A6 Paladin
 [Figure 3]. The 
M109  series of howitzers has been in  service for over half  a  century, and has been 
modernized repeatedly. The latest version, currently in low-rate initial production, is the 
M109A7 
[Figure 4]. When fielded, the M109A7 will  be almost a completely different 
vehicle than the original  109.  It,  and its  companion ammunition supply vehicle, the 
M992A3, have been rebuilt around a new hull that has substantial commonality with the 
Bradley  fighting vehicle.  Although  some elements of  the  weapon system are  being 
improved in the new vehicle, the major improvements will be on the vehicle’s reliability 
and automotive performance.29

Also from the 2019 RAND report: 
Rocket/Missile Systems 
The Army has two rocket launcher systems: the tracked M270A 1 Multiple Launch Rocket 
System (MLRS)
 [Figure 5] and the wheeled M142 High Mobility Artillery Rocket System 
(HIMARS
) [Figure 6]. Both systems fire the same family of 227mm  rockets, as well as a 
tactical ballistic missile, the Army Tactical Missile System (ATACMS).30 Both are fielded 
in  field  artillery  brigades and in  some cases  at the division level.  Figure 4.2  shows 
HIMARS firing ATACMS. Compared with cannons and mortars, the Army’s rockets fire 
much farther and carry much heavier lethal payloads. Although originally  designed with a 
very heavy Dual-Purpose Improved Conventional Munition (DPICM)31 payload, the main 
rocket currently employed is the GPS-guided M31 Guided Multiple Launch Rocket System 
(GMLRS)  rocket32, which has a unitary HE  warhead. The rockets are loaded onto the 
                                              
30 According to the Army, “ Army T actical Missile Systems (AT ACMS)  are 24/7, all-weather, surface-to-surface, 
inertially-guided  missiles  used  to engage  targets in the corps/Army area of influence. AT ACMS  were  used  extensively 
in both Operation Desert Storm (1991) and in Operation Iraqi Freedom (2003) ground wars  for shaping operations by 
the joint force, Joint Special Operations Forces and Army Land Component Command at operational levels. T here is 
one missile  per launching assembly  (missile pod) with two missiles  per launcher load in the M270/ M270A1 Multiple -
Launch Rocket System and one missile  in the M142 High Mobility Artillery Rocket System launcher,” 
https://asc.army.mil/web/portfolio-item/atacms/, accessed February 10, 2021. 
31 DPICM munitions contain hundreds of smaller “cluster bomb” explosives that are often left unexploded across the 
battlefield, which  creates a danger  to civilians. Currently, efforts are underway  to develop news  types of munitions that 
have similar effects but do not present the residual hazard of unexploded munitions.  
32 According to the Army, “ Guided  Multiple Launch Rocket System (GMLRS)  is a surface-to-surface system used  to

launchers in pods of six; two pods may be loaded onto the MLRS launcher, while HIMARS 
can carry one. 
In addition to rockets, both launchers can fire the MGM-140 ATACMS missile. Like  the 
MLRS rockets, ATACMS was originally developed with a submunition payload, but the 
primary version in current use has a unitary HE warhead (ATACMS Block 1A Unitary). 
ATACMS is a 610mm  missile that has a maximum range of about 300 km. 
Both  GMLRS  and ATACMS were  used extensively  in Iraq;   GMLRS,  being highly 
accurate and with a 200-lb unitary warhead that limits collateral damage relative to air-
delivered ordinance, has  earned a reputation for accuracy  and has been us ed in close 
proximity to troops. This is a somewhat atypical use of rockets, which historically  have 
often been used to saturate large areas with large amounts of explosives or large numbers 
of submunitions.33

attack, neutralize, suppress and destroy targets using  indirect precision fires up to 70 -plus km. GMLRS  munitions have 
greater accuracy than ballistic rockets with a higher probability of kill and a reduced  logistics  footprint. T he current 
GMLRS  family of munitions consists of three fielded  variants: Dual-Purpose Improved Conventional Munition 
(DPICM) and the Alternative Warhead (AW) variants to serv ice area targets; and the unitary variant with a single 200-
pound-class  high-explosive charge to service point targets with low collateral damage.  GMLRS  is  employed with the 
M270A1 Multiple Launch Rocket System and M142 High Mobility Artillery Rocket Syste m launchers,”

Description34 
The ERCA Program
 (Figure 7) is intended to develop a system that can accurately fire at targets 
more than 70 kilometers away—a dramatic increase over the 30 kilometers that a currently 
fielded M-1097A 155 mm howitzer can fire. The ERCA program essential y consists of two 
items: a new rocket-boosted shel , the XM1113, and a longer howitzer barrel adapted to the 
current M-1097A Paladin system. The longer barrel design contains the rapidly expanding 
propel ant gasses longer, which enables the projectiles to accelerate at greater speeds before 
exiting the muzzle. Also planned for development are an autoloader to increase the howitzer’s 
rate of fire as high as 10 rounds a minute (or one shel  every six seconds) and a communications 
system that are to work in GPS-denied environments. Initial plans cal  for 18 howitzers—a full 
battalion—entering service in 2023. The howitzers are being developed at the Army’s Picatinny 
Arsenal, New Jersey, and BAE Systems’ facilities in York, PA; Sterling Heights, MI; and 
Minneapolis,  MN.

Program Summary 
The Government Accountability Office (GAO) provided the following ERCA  program summary: 
The Army’s ERCA program is an upgrade to the M109 self-propelled howitzer intended 
to improve its lethality, range, and reliability. ERCA Increment 1C, a middle-tier35 rapid 
prototyping effort, will add equipment to the existing M109 vehicle to mature the design 
of the upgrade. The Army also plans an Increment 2 effort that will  include additional 
vehicle enhancements. We assessed the Increment 1C rapid prototyping effort. 
The Army initiated ERCA  Increment 1C as a  middle-tier acquisition rapid prototyping 
effort in September 2018 with an objective of building 18 prototypes equipped with new 
armament, electrical systems, and other upgrades beginning in fiscal year 2021. The Army 
plans to issue the prototypes to a battalion for operational testing by fiscal year 2023. The 
rapid prototyping effort is projected to end in October 2023 with the 18 prototypes issued 
to the battalion to gather information for  future ERCA  increments. In  July 2019,  the 
program made an award using other transaction authority to BAE Systems for Increment 
1C  engineering analysis, prototype hardware fabrication and integration, and  power 
updates. The Army also plans to make multiple additional awards in the future using other 
transaction authority for integration support, prototype fabrication, steel gun mount, and 
loader assist prototypes. 
The Army plans a separate Increment 2 effort, which it expects will leverage the cannon 
and other components designed in Increment 1C. The Army currently expects to also use 
the middle-tier rapid prototyping pathway for this effort, and plans to build and issue 18 
prototype vehicles starting in fiscal year 2024.36 
In its report, GAO noted that “the program also did not have a cost estimate informed by 
independent assessment or formal schedule risk assessment at the time of program initiation,” and 
that “the Army currently expects Increment 1C to cost approximately $486 mil ion.”37 According 
to the Army, anticipated funding from FY2022 to FY2026 of approximately $1.4 bil ion  is 
intended to 
  fully fund the part of the program intended to extend the system’s range beyond 
70 kilometers; 
  complete prototype testing and conduct operational assessment to gain soldier 
feedback; 
  procure 77 ERCA vehicles equipped with increased range capability; and 
  continue efforts exploring material solutions to improve ERCA rate of fire.38 
                                              
35 According to the Defense Acquisition University, “ Middle T ier Acquisition (MT A) is a rapid acquisition interim 
approach that focuses on delivering capability in a period of 2 -5 years. T he interim approach was granted by Congress 
in the FY2016 National Defense Authorization Act (NDAA) Section 804 and is not to be subject  to the Joint 
Capabilities  Integration Development System (JCIDS) and DOD  Directive 5000.01 ‘Defense Acquisition System.’ T he 
approach consists of utilizing two acquisition pathways: (1) Rapid  Prototyping and (2) Rapid Fielding.  It does this by 
streamlining the testing and deployment of prototypes or upgrading existing systems with already proven technology. ”

Program Developments 
In December 2020, a prototype ERCA system reportedly hit a target 70 kilometers (43 miles) 
away during testing at Yuma Proving Ground, Arizona.39 According to the Army, in October 
2019, it conducted demonstrations of the new XM1113 and Excalibur M982 munitions from a 
prototype ERCA self-propel ed howitzer and test shots exceeded previous maximum ranges.40 
Internal Army efforts to design an autoloader have reportedly run into developmental difficulties, 
with the Army looking to smal  business for alternatives.41 Given these setbacks, some say a 
functioning autoloader capacity for the ERCA  may not be available  by 2024, as previously 
planned.42

Description 
According to the Army,43 the Precision Strike Missile (PrSM)
 (Figure 8) is a surface-to-surface, 
al -weather, precision-strike guided missile fired from the M270A1 Multiple  Launch Rocket 
System (MLRS) and the M142 High Mobility Artil ery Rocket System (HIMARS). PrSM, which 
is intended replace ATACMS, doubles the current rate-of-fire with two missiles per launch pod. A 
bal istic missile with a cluster munition-compliant payload, the PrSM is to be used for attacking 
threat air defense systems, missile launchers, command and control centers, troop 
assembly/staging areas, and high-payoff targets throughout the battlefield. The missile is designed 
to exceed a range of more than 500 kilometers.44 Lockheed Martin is currently the PrSM’s only 
prime contractor.  
Program Summary 
According to GAO: 
The Army plans to conduct an independent technical risk  assessment  prior to PrSM’s 
expected development start in June 2021. Army officials report that in the meantime, they 
are taking steps to mitigate technology risk. For example, the Army conducted a prototype 
missile test to a range of 240 kilometers in December 2019. The Army plans to demonstrate 
the objective range of 499 kilometers at a later date, but program officials said that they 
have yet to schedule that test. 
The Army initially tested the missile with the M142 rocket launcher. Demonstrations with 
the M270A2 launcher are dependent on completion of upgrades to that system. According 
to program officials, the Army will complete these upgrades by fiscal year 2023 to support 
the missile’s early capability.45 
The Army plans to start operational testing in August 2024 and achieve Initial Operational 
Capability  in August 2025.46 Estimated program costs and quantities (in FY2020 dollars in 
mil ions) are $895 mil ion  for development and $2,038 mil ion for procurement, for a total of 51 
missiles for testing and 2,422 for the approved acquisition objective.47 
Program Developments 
On December 10, 2019, Lockheed Martin reportedly conducted a successful test at the White 
Sands Missile Range, NM, where the PrSM was successfully fired from a HIMARS and flew 
about 240 kilometers to the target area.48 In April 2020, Lockheed Martin conducted its third 
successful test, whereas Raytheon reportedly decided in March 2020 not to continue its 
participation in the development and testing phase, but plans to compete in future PrSM 
development phases.49 In May 2020, the Army reportedly drafted “an acquisition strategy cal ing

for at least three additional  opportunities for competition on the Precision Strike Missile, giving 
Raytheon—which was bumped from the contest in March—and other interested companies a 
chance to improve the base missile being developed by Lockheed Martin as a follow-on to the 
Army Tactical Missile.” 50 In June 2020, the Army reportedly completed a test of an advanced 
PrSM multi-mode seeker (presently radio frequency [RF] and imaging infrared [IR]).51 The 
seeker is intended to locate targets in a denied environment and engage targets with unknown or 
poorly located coordinates, such as ships moving at sea.52 
Strategic Long Range Cannon (SLRC) 
Description 
The Army is reportedly examining the feasibility of developing a cannon that can fire a projectile 
at hypersonic speeds up to 1,000 miles to engage air defense, artil ery, and missile systems and 
command and control targets.53 The SLRC is to consist of a cannon, prime mover and trailer, and 
projectiles capable of delivering massed fires at strategic ranges.54 The SLRC battery is to include 
four special platforms with cannons and heavy equipment transporters for the battery’s other 
equipment. Each SLRC could be manned by a crew of eight soldiers.55 
Program Summary 
The SLRC is not currently a program of record.56 The Army plans to demonstrate a prototype of 
the long-range cannon in 2023, after which it intends to decide whether to begin a program of 
record.57 Some observers have suggested that “the technology needed to achieve such a capability 
is so cutting edge that it’s unknown whether that specific distance can be achieved at a cost that 
won’t break the bank.”58 In addition to cost concerns that some have raised, some also have 
concerns regarding the Army’s ability to acquire and engage targets at these extended ranges with 
its own organic assets.59 
Some in Congress have expressed concerns about the feasibility of, and need for, the SLRC. For 
example, H.Rept. 116-120 of the FY2020 NDAA  (P.L. 116-92) cal s for the National Academies

of Sciences, Engineering, and Medicine to examine the feasibility of the U.S. Army’s Strategic 
Long Range Cannon program.60 Among other things the study is to 
  assess the technology approaches, policies, and concepts of operations of the 
Army’s SLRC and how it supports the Army’s Multi Domain Operations (MDO) 
vision, and 
  evaluate the essential technologies, materials, and manufacturing capabilities 
needed to achieve the program’s key performance criteria and develop a 
technology maturation roadmap.  
The report was due to defense committees no later than August 31, 2020, but was not provided by 
that date. The report is now reportedly expected to be delivered to the defense committees 
sometime in May 2021.61 Reportedly, some unspecified work continues on SLRC but the Army is 
awaiting the findings of the report before continuing further development.62 
Program Developments63 
The Army reportedly has already started firing test loads over short ranges to determine SLRC 
propel ant and projectile requirements. As previously noted, the Army plans to start building a 
functioning SLRC weapon in 2021, with limited-range first test shots likely to begin in 2022, 
followed by full-range shots in 2023. Based on these results, the Army intends to decide whether 
or not to develop the SLRC as a program of record.

Description 
According to the Army: 
Hypersonic weapons are capable of flying at five times the speed of sound and operate at 
varying altitudes, making them unique from other missiles with a ballistic trajectory. The 
Army Long Range Hypersonic Weapon (LRHW)
 [Figure 9] will introduce a new class of 
ultrafast,  maneuverable,  long-range  missiles  that  will  launch  from  mobile  ground 
platforms.64 
Program Summary 
According to the Army: 
Developing hypersonic weapons for a national mission set requires  constant cross-service 
coordination. Collaborating across services, agencies and with the Office of the Secretary 
of Defense through a joint service memorandum of agreement on design, development, 
testing and production, the Army, Navy, Air Force and the Missile Defense Agency (MDA) 
are  all  accelerating  initiatives to field  hypersonic weapon systems  using a Common

Hypersonic Glide Body (C-HGB).  The Navy leads design of the C-HGB, while the Army 
will  lead production and build a commercial industrial base. This cooperation enables the 
services to leverage one another’s technologies as much as possible, while tailoring them 
to meet specific design and requirements for air, land and sea.65 
The Army’s intent is to 
[f]ield a prototype long-range hypersonic weapon to the strategic fires battalion by fiscal 
year 2023. This includes hypersonic missiles with the C-HGB, existing trucks and modified 
trailers with new launchers, and an existing Army command -and-control system.66 
Program Developments 
According to the Army: 
In March 2019,  the Secretary and Chief of Staff  of the Army directed the accelerated 
delivery  of  a  prototype ground-launched hypersonic  weapon with  residual  combat 
capability by Fiscal Year (FY) 2023. To execute this strategy, the Army Rapid Capabilities 
and Critical Technologies Office (RCCTO) has selected two prime contractors to build and 
integrate components of the LRHW prototype. On August 29, the Army awarded an Other 
Transaction Authority (OTA) agreement to Dynetics in the amount of $351.6 million  to  
produce the first commercially manufactured set of prototype Common -Hypersonic Glide 
Body (C-HGB) systems. Also on August 29, the Army awarded a second OTA67 agreement 
to Lockheed Martin in  the amount of  $347.0  million  as the LRHW  prototype system 
integrator.68 
Reportedly, “the Army has set an ‘aggressive’ test plan for the LRHW program that cal s for six 
flights, including two executed by soldiers who wil  operate the first battery of the new ground-
launched strategic weapon, by 2023.”69 On March 19, 2020, the Army and Navy reportedly 
successfully test-fired the C-HGB at the Pacific Missile Range Facility, in Kauai, HI, clearing the 
C-HGB for further development.70 
Other Army Missile Efforts 
According to reports, the Army is pursuing a new mid-range missile system or systems capable of 
attacking moving targets at land and at sea.71 The effort is intended to fil  a gap in the Army’s

67 From the Defense Acquisition  University: “ Other Transaction Authority (OT A) is the term commonly used to refer 
to the (10 U.S.C. 2371b) authority of the DOD to carry out certain prototype, research and production projects. Other 
T ransaction (OT ) authorities were created to give DOD the flexibility necessary to adopt and incorporate business 
practices that reflect commercial industry standards and best practices into its award  instruments. As of the 2016 
National Defense Authorization Act (NDAA) Section 845, the DOD currently has permanent authority to award OT  
under (10 U.S.C.  2371) for (1) Research, (2) Prototype, and (3) Production Purposes. ” [quotation marks correct?]

long-range precision fires portfolio, which includes the PrSM and LRHW.72 In early 2020, the 
Department of Defense reportedly determined the Army should be assigned a mid-range 
capability mission.73 Seeming to affirm this, in July 2020, Army Chief of Staff General James 
McConvil e suggested that “the Army would pursue mid-range capabilities, and that, “we’re 
going to have mid-range missiles that can sink ships.”74 During a Rim of the Pacific (RIMPAC) 
exercise in 2018, the Army test-fired “multiple rockets from the rocket artil ery platform at the 
ex-USS Racine during a combined arms sinking exercise.”75 
According to reports, the Army is exploring the possibility of converting existing U.S. Navy 
missiles for that purpose: 
On November 6, 2020, the Army awarded Lockheed Martin a $339.3 million  contract to 
“design, build, integrate, test, evaluate, document, deliver, and support” a new Mid-Range 
Capability, or MRC, essentially converting the Navy Standard Missile (SM)-
6 [Figure 10] 
and Tomahawk cruise missiles 
 [Figure 11] into a prototype land-based missile system that 
can strike targets in the range of 500 to 1,500 kilometers, or 310 to 930 miles. The effort 
builds off tests that the Army conducted last August. The goal is to have an operational 
new land cruise missile by 2023….  After that 2023  date, the Army  will  “explore  the 
possibility” of going “beyond the prototype and see if that mid-range capability could be 
integrated onto an autonomous launcher that would augment existing formations.”76 
If the prototype proves successful, the Army reportedly would organize units into batteries77 
composed of a battery operations center with three parts: a command and control center, a 
launcher, and the missiles, with four and six missiles per battery.78 
Congressional Concern with LRPF Programs 
Many in Congress have also expressed concern with both Army and Marine LRPF efforts, 
including its use in an anti-ship role. Section 1715 of the FY2020 National Defense Authorization 
Act (NDAA) (P.L. 116-92) states: 
a) IN GENERAL.—Not later than March 1, 2020, the Secretary of Defense shall submit to 
the Committees on Armed Services of the Senate and House of Representatives a report on 
the efforts by the Army and Marine Corps to develop and deploy ground-based long-range 
rocket and cannon artillery to counter land and maritime threats. 
(b)  ELEMENTS.—The  report required  by  subsection (a)  shall  include  each of  the

Potential Issues for Congress 
There are a number of potential issues Congress may face relating to the Army’s Long-Range 
Precision Fires Program. Potential issues include, but are not limited to, the following: 
Justification for Strategic Cannons, Hypersonics, and Mid-Range 
Battlefield Missiles 
Many would argue that Army programs such as the ERCA and PrSM are logical upgrades and 
improvements to proven legacy weapons systems to counter potential adversaries with 
significantly improved artil ery systems and associated capabilities of their own. ERCA and 
PrSM are considered fundamental components of the Army’s traditional battlespace, and they 
play an important fire support role in brigade, division, and corps-level ground combat 
operations—a role that the Army has organized, equipped, and trained for arguably since the 
Second World War to present day.  
The Army says that longer-range artil ery systems are needed to respond to what DOD cal s the 
enemy anti-access, area denial (A2/AD) environment (layered and integrated long-range 
precision-strike systems, littoral anti-ship capabilities, air defenses, and long-range artil ery and 
rocket systems), which can theoretical y keep U.S. forces at bay and deny freedom of movement. 
Under this premise, the Army developed its MDO operational concept and is prioritizing and 
focusing its modernization efforts to support MDO and the Army’s ability to counter A2/AD 
systems. 
Some analysts, however, suggest the potential threat from enemy A2/AD systems is overstated 
and perhaps unfounded. A 2019 report from the U.S. Army War College states: 
Exaggeration and hype suggesting Russia has the ability to interdict its adversaries across 
large areas of European air and maritime space in particular leads to a distorted picture. If 
left  uncorrected, these inaccuracies could influence  policy  by  constra ining response 
Congressional Research Service

options for assertive Russian maneuvers. A public perception that allied reinforcement of 
the Baltic States is not possible during a time of conflict, for example, will falsely limit the 
options palatable to US policymakers. Neat circles on a map, while important for drawing 
attention to the problem, also foster the public impression of “no-go zones” that would be 
lethal for US or allied military assets. But Russian A2/AD systems will not prevent NATO 
forces from getting to frontline states. They could, however, prevent NATO from trying at 
all.80 
This report further contends: 
Russia commonly demonstrates its air defense capabilities and exploits the myth of A2/AD 
“bubbles” among its neighbors to sow doubt among NATO allies. In doing so, the Kremlin 
uses Western insecurities regarding ensured access to its advantage and feeds a perception 
that NATO cannot operate effectively in a contested environment. The ongoing debate thus 
becomes a self-constructed psychological threat that reflects Western insecurities toward 
Russia, thus constituting a way for the Kremlin  to be blamed for the West’s capability 
shortfalls.81 
Another report proposed in 2015 that China’s A2/ASD strategy is the result of a misconception 
regarding potential  U.S. military interventions in China: 
Yet,  although China is certainly developing military capabilities that would complicate 
U.S. intervention in a major conflict in the region involving China, Chinese writings on 
military strategy and operations rarely if ever mention the concept of counter-intervention. 
Despite the frequent use of the term by outside observers—who attribute the concept to 
Chinese sources—the Chinese military does not use the term to describe its own strategy. 
When it does discuss related concepts of “dealing with” or  “resisting”  a third party’s 
military intervention, it mentions them as a sub-component of one of the core campaigns 
or scenarios that drive Chinese planning, such as an armed conflict over Taiwan, not as an 
overarching strategy. The absence of the  term  and infrequent use of related ideas in 
authoritative  Chinese military  writings does not appear to reflect a  larger  denial-and-
deception campaign, since this literature often involves much more sensitive subjects. 
This omission matters for several reas ons. Identifying “counter-intervention” as the focus 
of  China’s military  strategy, and attributing it to  Chinese sources, sustains a flawed 
assessment of China’s military  modernization, mistaking an  operational concept for a 
military  strategy or even a grand strategy aimed at pushing the United States out of the 
Asian littoral. China’s military  modernization pursues several different goals, some of 
which might require dealing with potential U.S. military intervention, while others do not. 
Even within  a  Taiwan scenario, countering U.S.  intervention is only one of  a  set of 
operations that the People’s Liberation Army (PLA) believes it would need to undertake in 
such a campaign. More generally, the focus on “counterintervention” overstates the role of 
the United States in Chinese military planning and contributes to the security dilemma as 
well as growing security competition in the region.82 
The Center for a New American Security (CNAS) further chal enges the role A2/AD plays in 
current DOD and Army thinking:

U.S. Army Long-Range Precision Fires: Background and Issues for Congress  
 
For at least a decade, A2/AD has helped focus the DOD on critical Chinese and Russian 
threats to U.S. military operations in East Asia and Eastern Europe. Today, however, it has 
outlived its usefulness as a diagnosis of Chinese and Russian approaches to warfare and as 
a framework for guiding subsequent operational and force-planning decisions based on the 
challenges they pose. Terminology and words matter, most acutely in problem diagnosis…. 
If  the DOD  cannot  move  beyond  A2/AD, it  risks wasting  billions of taxpayer dollars 
building a future force based on a flawed premise. More worryingly, it puts the United 
States at greater risk of losing a future war against China or Russia.83 
Given these assertions, some may argue that justification for the development of longer-range 
Army systems primarily on the basis of countering enemy A2/AD and the ability  to prosecute 
MDO may be based more on a perception of enemy capabilities and strategy than on an enemy’s 
actual intent and capabilities. Although developing and deploying Army strategic cannons, 
hypersonic weapons, and mid-range missiles would increase both the range and capabilities of 
Army artil ery systems, the articulated need for these systems, in terms of countering enemy 
A2/AD, some could argue, may be overstated. A focus on longer-range cannons and missiles to 
counter A2/AD, some may contend, could compromise the Army’s ability to provide artil ery 
support to brigade, division, and corps-level ground combat operations by consuming resources 
and funding in a potential budgetary- constrained environment that might otherwise be dedicated 
to improving ground-based combat capabilities within the Army’s traditional battlespace. 
Estimated LRPF Total Costs 
As the Army’s stated modernization priority, Congress may consider whether long-range 
precision fires should receive funding priority. Although some estimated individual  program costs 
are publicly  available  for selected programs and efforts in the Army’s LRPF portfolio, these costs 
tend to focus on system-specific Research, Development, Test & Evaluation (RDT&E) and 
procurement costs and not overal  associated costs. 
Overal  cost is reflected in the “DOTMLPF-P”84 cost—that is, costs associated with developing 
and implementing associated 
Doctrine; creating new or modifying existing 
Organizations; 
Training  soldiers and units; acquiring 
Materiel;  changes needed in 
Leadership and education; 
new or existing 
Personnel requirements; new or modified 
Facilities (including training ranges); 
and changes in 
Policy. In some cases, this cost can be relatively minimal;  in other cases, 
particularly those involving new, technological y advanced weapon systems, this cost can be 
more substantial. Sometimes, the DOTMLPF-P cost can be reduced by introducing a new system; 
for example, one that requires fewer personnel to operate, has fewer and less costly maintenance 
requirements, or can deliver the same doctrinal y-required effects more efficiently. The PrSM, 
which comes two missiles to a launch pod rather the current single missile per launch pod 
configuration of ATACMs, is an example of such a system. 
Some policymakers may seek a better understanding of DOTMLPF-P costs, not only for the 
aforementioned LRPF systems under development, but also for the Army’s LRPF portfolio as a 
whole. In the case of the SLRC and LRHW programs, as previously noted, some observers have 
expressed concerns about the costs associated with developing and fielding these capabilities. In 
addition, Army efforts to develop a mid-range missile capability—even if based on modifying

and acquiring existing Navy systems—could likewise prove costly. In addition, a DOTMLPF-P 
cost breakdown could prove beneficial if the Army is required to make tradeoffs within its LRPF 
portfolio due to affordability issues. 
As part of a DOD review prior to the submission of President Biden’s FY2022 defense budget 
request, “long-range fires, such as artil ery and ground-to-ground missiles,” are to be considered 
for reductions or curtailment in order to fund the President’s other defense priorities.85 If this is 
the case, knowing the total costs for LRPF systems and the LRPF portfolio could benefit both 
defense officials and policymakers during the DOD review process. 
LRPF and the U.S. Indo-Pacific Command’s Investment Plan for the 
Pacific Deterrence Initiative 
In testimony to the Senate Armed Services Committee on March 9, 2021, the Commander of the 
U.S. Indo-Pacific Command (USINDOPACOM) stated; 
USINDOPACOM requires highly survivable, precision -strike fires  featuring increased 
quantities of ground-based missiles and improved air and long-range naval fires capable of 
ranges over 500 km. These fires must be supported by electronic warfare, space, cyber, and 
over-the-horizon radar capabilities. They must also be operationally decentralized and 
geographically distributed to provide a credible, offensive, and conventional deterrent to 
assure U.S. freedom of action.86 
Section 1251 of the National Defense Authorization Act (NDAA) for FY2018 (P.L. 115-91), as 
amended by Section 1253 of FY2019 NDAA  (P.L. 115-232), authorized the Indo-Pacific Stability 
Initiative to enhance the security and stability of the Indo-Pacific region. Section 1251 of the 
FY2021 NDAA (P.L. 116-283) requires the Commander of U.S. Indo-Pacific Command 
(USINDOPACOM) to provide, no later than March 1, 2021, an independent assessment to 
Congress outlining USINDOPACOM’s resourcing requirements for what is now referred to as the 
Pacific Deterrence Initiative (PDI). In its report to Congress, USINDOPACOM requests $408 
mil ion  for FY2022 and $2.91 bil ion  for FY2023-FY2027 for “Ground-Based, Long-Range 
Fires” that are “highly survivable, precision-strike fires can support the air and maritime 
maneuver from distances greater than 500 km.”87 While no additional detail is provided in this 
unclassified version, the report notes that “strategic context and more detailed funding profiles are 
provided in the classified version of this report,”88 suggesting that additional information related 
to the Army’s LRPF programs may be included in the report’s classified version. 
Policymakers may review the classified version of USINDOPACOM’s report to determine if 
there are cost and funding implications for the Army’s LRPF programs and associated force 
structure requirements. Furthermore, the classified report might also address where Army LRPF 
units are to be stationed, which could have operational and cost implications. If the classified

version does not contain this level of detail, Congress might examine these issues further with 
DOD and USINDOPACOM.  
Force Structure Requirements 
With the possible introduction of new LRPF systems, the Army could be required to create units 
to employ and support these systems. In such cases, the Army has three basic options to obtain 
the necessary soldiers: 
  The Army could request additional end strength from Congress as part of annual 
budget requests.89 
  The Army could convert an existing unit into a new unit. For example, the Army 
could convert a towed 155 mm howitzer battery into a LRHW battery. 
  The Army could deactivate a unit and “use” that unit’s end strength to form a 
new unit. For example, the Army could deactivate an infantry battalion and use 
its end strength to form a mid-range missile battalion. 
The Army does not necessarily have to pick one of these options, as al  three can be used 
concurrently. The Army has the option to request an end strength increase from Congress. 
However, recent statements from Army leadership proposing that the Army might have to cut end 
strength to fund modernization90 suggest that such a request for new LRPF units may be unlikely 
under current budgetary constraints. 
Although the Army has been specific about the LRPF systems it plans to develop, little has been 
publicly discussed about the conversion or creation of units to employ or support these systems. 
While references have been made to LRHW and mid-range missile batteries, a Multi-Domain 
Task Force (MDTF)—an Army unit under development which could be equipped with land-
based, deep strike capabilities—as wel  as a notional Strategic Fires Battalion, little  has been said 
about the following concerns: 
  how these units would be organized and equipped; 
  how many batteries and battalions are planned to be formed; 
  when these units would become operational; 
  how many soldiers would be required for these units; and 
  where LRPF units might be stationed in the United States and overseas. 
In addition to LRPF units themselves, new headquarters and support units might be required to 
support LRPF units, such as target acquisition, missile maintenance, and other types of logistical 
units. These units have similar personnel, equipment, and stationing requirements which would 
also need to be considered when discussing LRPF units. 
If the Army intends to request additional end strength for LRPF and associated units, there are 
budgetary implications for Congress. In addition, new LRPF and associated headquarters and 
support units could require significant numbers of vehicles and types of new equipment, which                                               
89 In accordance with 10 U.S.C.  §115, Congress annually authorizes the end strength for active duty and reserve 
component personnel. End strength is the maximum number of personnel permitted in each military service (e.g., 
Army, Marine Corps, Navy, Air Force) as of September 30, the last day of the fiscal year.

would also have cost implications. If the Army intends to deactivate or convert units, doing so 
could have operational implications that Congress may discuss with DOD and the Army.  
Another concern for Congress might be where these new units are to be based. Reportedly, 
consideration is being given to stationing a Multi-Domain Task Force (MDTF) in the uninhabited, 
Japanese-controlled Senkaku Islands (referred to as the Diaoyu Islands by China) but additional 
diplomatic coordination is required before a final decision can be made.91 Particularly in the case 
of stationing LRHW and mid-range missile units overseas, there are likely numerous political 
considerations that policymakers might explore with the Administration and DOD.  
LRPF in the Reserve Components 
As of March 1, 2021, approximately 57 % of Army artil ery  battalions were in the Army National 
Guard (ARNG). While little has been said publicly about the al ocation of LRPF systems and 
units, it is possible that some LRPF systems and units could be in the ARNG. If LRPF systems 
and units are al ocated to the ARNG, potential questions for policymakers include the following: 
  Which ARNG units are planned to receive LRPF systems and/or units? 
  When would these units receive LRPF systems, and when would new LRPF units 
be activated? 
  Would existing ARNG units be converted to LRPF units or LRPF support units? 
  Wil   any existing ARNG units be deactivated to facilitate the creation of ARNG 
LRPF or LRPF support units? 
  Are there special training requirements associated with LRPF systems and, if so, 
how wil  they apply to ARNG soldiers? 
  Are there any special range or military construction requirements associated w ith 
ARNG LRPF systems or units? 
  In the event that the ARNG is not planned to receive LRPF systems or units, 
what is the Army’s rationale for this decision? 
Other Services’ Views on Army LRPF 
The Army is working with both the Navy, Marine Corps, and Air Force on LRPF.92 As previously 
discussed, al  three Services are involved in developing a Common Hypersonic Glide Body (C-
HGB), and the Army is evaluating  Navy Standard Missile (SM)-6 and UGM-109 Tomahawk 
cruise missiles as part of its mid-range missile effort. Some concerns reportedly have been raised 
by another service about the Army’s longer-range systems. 
One article explains: 
The baseline version of the Lockheed Martin Precision Strike Missile will enter service in 
two years with a range of 499  km,  but a follow-on version due to be ready in 2025  is 
expected to have a range up to 800 km.  Moreover, the Army has selected the Raytheon 
SM-6 ballistic missile and UGM-109 Tomahawk cruise missile for a new ground-launched 
role,  with ground-launched prototypes scheduled  to  debut in 2023.  At the same time,

Lockheed should be fielding the first Long-Range Hypersonic Weapon, a rocket-booster 
glider with a conventional warhead. 
Once those weapons arrive, the Army will no longer 
rely on the Air Force’s inventory of bombers and fighter-bombers to hunt and destroy 
targets deep inside enemy territory [emphasis added].93 
Furthermore, affordability issues are raised: 
Some Air Force officials have already pushed back. “If the Air Force can do something—
long-range strike, maybe—one  of the services doesn’t have to do it,”  Lt.  Gen.  David 
Nahom, the Air Force’s deputy chief of staff for plans and programs, said in August [2020]. 
“But all of us investing in a single area in just a slightly different way—it’s just not going 
to be affordable.”94 
It has been suggested that Army LRPF could be an encroachment on traditional y agreed-to roles 
and missions:  
It’s ridiculous, to be quite candid. It is encroachment on roles and missions. The fact of the 
matter is the services need to adhere to their core competencies. And the United States 
Army reaching out to develop weapon systems that operate at thousand-mile range truly is 
encroachment.95 
The U.S. Marine Corps is also expanding its long-range precision fires capabilities. The Marines 
are working with the Army on a variety of land-based options: 
Land-Based Anti-Ship Missile (LBASM) options on the table for ground forces to use 
against threatening enemy ships since the United States abandoned the INF Treaty. The 
Long-Range Precision Fires (LRPF)  Anti-Ship missile options include: The long-range 
subsonic Maritime Tomahawk, the ATACMS to Precis ion Strike  Missile [PrSM],  the 
stealthy Long-Range Anti-Ship Missile (LRASM), the stealthy Naval Strike Missile, and 
the high-speed SM-6 multi-role missile.96 
Reportedly commenting on LRPF differences between the Army and Marines, General David H. 
Berger, Commandant of the Marine Corps, stated, “The [U.S.] Army is pursuing longer-range, but 
much larger, heavier, bulkier systems than we are. But they’re not either or; we’re going to need 
both [U.S. Army and USMC].”97 
The Army reportedly contends there is no service rivalry or role and mission encroachment, and 
that al  Services are required to address the potential Russian and Chinese A2/AD threat.98 
Furthermore, the Army reportedly suggests land-based LRPF systems offer advantages over other 
air or sea-launched systems: 
  
Concealability. Aircraft and surface warships can be designed with stealth 
features to hide from radar but are not undetectable. Airbases offer large static

targets. Artil ery and missile units can be camouflaged or hidden in underground 
tunnels, as demonstrated by North Korea.99 
  
Range. Military aircraft can refuel in mid-air, extending flight indefinitely, but 
fuel tankers are vulnerable and “unstealthy,” considered too vulnerable to fly 
close to Russian or Chinese air defenses. While Air Force strategic bombers have 
ranges of thousands of miles, the majority of Air Force, Navy, and Marine strike 
aircraft are fighters—F-15s, F-16s, F-18s, and F-35s—with ranges of hundreds of 
miles from ground bases or aircraft carries.100 
  
Complexity. Arguably, it is easier to launch a missile “off the back of a truck 
than from an aircraft, surface ship, or submarine,” potential y making “land-
based systems cheaper and quicker to develop.”101 
Given the range of views expressed by the Services, Congress might decide to examine these 
issues. Wil  Army LRPF systems have an impact on the requirements for other Service’s systems, 
such as Air Force long-range bombers? Wil  the development of Army LRPF systems grant the 
Army a degree of independence from the other Services for long-range fire support and, if so, 
would this free up those Service’s assets previously dedicated to support the Army for other 
missions or uses? With the Army and Marines expanding their LRPF capabilities, is there now 
redundant capability within the Services, or are al  of these assets and capabilities (and perhaps 
more) needed to address perceived Russian and Chinese threats? 
Commanding and Controlling and Targeting Long-Range Fires 
In developing LRPF systems to deliver fires, another consideration is the ability to command and 
control them and to detect, acquire, and engage targets. One defense analyst summarizes the issue 
and related chal enges: 
Target spotting for field artillery typically is provided by warfighting systems organic to 
the  Army,  such as  scout helicopters and  reconnaissance drones. But  when  targets 
potentially are a thousand miles away, a different approach will be needed ... much of the 
targeting  information will  be provided by space-based assets. That presumably means  
relying on what used to be called “national technical means,” or spy satellites. Targeting 
information might also be provided by the F-35 fighter, which is nearly invisible to enemy 
radar and has extensive recon capabilities ... classification (secrecy) level of overhead 
collections will need to be changed to gain access to much of the required information, but 
that’s just the beginning of the challenge. The Army will  need a network that connects 
sensors to shooters with minimal  delay. The Army informally  refers to overcoming the 
sensor-to-shooter challenge in next-gen systems as “convergence,” but optimizing the use 
of very long-range weapons will require a targeting network that spans the entire joint force 
and beyond, because key sensors have diverse owners.102 
Another concern that has been raised is who decides how targets wil  be engaged: 
Who calls for fires? The Army is probably going to regret using the term “strategic” in the 
name of its long-range cannon, because in American usage that implies complicated release 
authority for weapons whose use could raise far-reaching issues. It might not be the case

in the Pacific, where distances are so great that a thousand miles is the range at which some 
tactical targets might need to be engaged (think Chinese warships). But in the close quarters 
of  the  European theater, a  weapon with  that sort  of  reach  potentially raises major 
geopolitical questions. After all, it is only 700 miles from Warsaw to Moscow.103 
Reportedly, the Army is exploring how to use satel ites for identifying targets for long-range 
precision fires systems.104 While reliance on space-based assets is not unique for Army combat 
systems, if space-based assets are attacked by adversaries and destroyed or disrupted, LRPF 
systems might not be able to detect, acquire, and engage targets.  
The Army intends to rely on DOD’s Joint Al  Domain Command and Control (JADC2) system 
presently under development.105 The JADC2 system envisions linking sensors and shooters across 
air, land, cyber, and sea to detect and acquire targets for its LRPF systems. To test this theory, the 
Army is presently conducting a series of experiments under what it cal s Project Convergence.106 
In 2020, the Army conducted its inaugural Project Convergence exercise at Yuma Proving 
Ground, AZ, and plans cal  for exercises in 2021 and 2022. During these exercises, the Army 
intends to work with the other Services and al ies to test, among other things, command and 
control and sensor-to-shooter linkages using both Service and national assets to facilitate long-
range precision fires. 
A great deal of attention is being given the various LRPF systems under development. How the 
Army intends to command and manage these systems, and how they would detect, acquire, and 
engage targets exceeding the range of current organic systems, could potential y be viewed as of 
equal and, perhaps, greater importance. While space-based assets might be a possibility, these 
systems can be readily targeted by various means, and if redundant systems are unavailable, some 
LRPF systems risk becoming expensive “single point of failure” weapons. With this in mind, 
policymakers might seek to examine the use of national space-based assets, capabilities being 
developing under JADC2, and the results of Project Convergence to determine if Army proposals 
for commanding LRPF units and detecting, acquiring, and engaging targets at long ranges are 
feasible.
