The Army’s Future Combat System (FCS): Background and Issues for Congress

Summary
The Future Combat System (FCS) was a multiyear, multibillion dollar program at the heart of the
Army’s transformation efforts. It was to be the Army’s major research, development, and
acquisition program consisting of 14 manned and unmanned systems tied together by an
extensive communications and information network. FCS was intended to replace current systems
such as the M-1 Abrams tank and the M-2 Bradley infantry fighting vehicle. The FCS program
has been characterized by the Army and others as a high-risk venture due to the advanced
technologies involved and the challenge of networking all of the FCS subsystems together so that
FCS-equipped units could function as intended.
The FCS program exists in a dynamic national security environment which ultimately played a
role in determining the program’s fate. Some questioned if FCS, envisioned and designed prior to
September 11, 2001, to combat conventional land forces, was relevant in current and anticipated
future conflicts where counterinsurgency and stabilization operations are expected to be the norm.
The Army contended, however, that FCS was relevant throughout the “entire spectrum of
conflict” and that a number of FCS technologies and systems were effectively used in
counterinsurgency and stabilization campaigns in Iraq and Afghanistan.
On April 6, 2009, Secretary of Defense Gates announced that he intended to significantly
restructure the FCS program. The Department of Defense (DOD) plans to accelerate the spin out
of selected FCS technologies to all brigade combat teams (BCTs) but will recommend cancelling
the manned ground vehicle (MGV) component of the program, which was intended to field eight
separate tracked combat vehicle variants built on a common chassis that would eventually replace
combat vehicles such as the M-1 Abrams tank, the M-2 Bradley infantry fighting vehicle, and the
M-109 Paladin self-propelled artillery system. Secretary Gates was concerned that there were
significant unanswered questions in the FCS vehicle design strategy and that despite some
adjustments to the MGVs, they did not adequately reflect the lessons of counterinsurgency and
close quarters combat in Iraq and Afghanistan. Secretary Gates was also critical that the FCS
program did not include a role for Mine-Resistant, Ambush-Protected (MRAP) vehicles that have
been used successfully in current conflicts. After re-evaluating requirements, technology, and
approach, DOD will re-launch the Army’s vehicle modernization program, including a
competitive bidding process.
Plans for transition from the FCS program to a new program where the Army intends to
modernize all BCTs with remaining FCS technologies will likely be of critical congressional
interest. The development of a new Ground Combat Vehicle (GCV) to replaced the cancelled
MGVs could also be subject to congressional debate and oversight. This report will be superseded
by a report on the Army’s BCT Modernization Strategy when sufficient details are available.

The Army’s Future Combat System (FCS): Background and Issues for Congress

Issues for Congress
The Future Combat System (FCS) was a multiyear, multibillion-dollar program at the heart of the
Army’s transformation efforts. It was to be the Army’s major research, development, and
acquisition program and was to consist of 14 manned and unmanned systems tied together by an
extensive communications and information network. FCS was intended to replace current systems
such as the M-1 Abrams tank and the M-2 Bradley infantry fighting vehicle. The Army’s success
criteria for FCS was that it should be “as good as or better than” the Army’s current force in terms
of “lethality, survivability, responsiveness, and sustainability.”1
The primary issues presented to 111th Congress are how the Army plans to transition from the
FCS program to a BCT Modernization Program, incorporating selected remaining FCS
technologies in a series of spin outs. Key oversight questions for consideration include the
following:
• What are some of the issues resulting from the cancellation of the MGV?
• What is the Army’s BCT modernization strategy and spin out plan?
• Is the Army rushing the GCV program?
• Will the Army replace the Non-Line-of-Sight Cannon (NLOS-C)?
• What is the impact on the Army’s operational concept, force structure, and
doctrine?
The 111th Congress’s decisions on these and other related issues could have significant
implications for U.S. national security, Army funding requirements, and future congressional
oversight activities.
Background
FCS Program Origins
In October 1999, then Chief of Staff of the Army (CSA) General Eric Shinseki introduced the
Army’s transformation strategy which was intended to convert all of the Army’s divisions (called
Legacy Forces) into new organizations called the Objective Force. General Shinseki’s intent was
to make the Army lighter, more modular, and—most importantly—more deployable. General
Shinseki’s deployment goals were to deploy a brigade2 in four days, a division in five days, and

Future Combat System’s Successful Outcome,” GAO-06-367, March 2006, p. 2.
2 According to Department of the Army Pamphlet 10-1, “Organization of the United States Army,” dated June 14,
1994, a brigade consists of approximately 3,000 to 5,000 soldiers and a division consists of approximately 10,000 to
18,000 soldiers.

five divisions in 30 days.3 As part of this transformation, the Army adopted the Future Combat
System (FCS) as a major acquisition program to equip the Objective Force.4
This transformation, due to its complexity and uncertainty, was scheduled to take place over the
course of three decades, with the first FCS-equipped objective force unit reportedly becoming
operational in 2011 and the entire force transformed by 2032.5 In order to mitigate the risk
associated with the Objective Force and to address the near-term need for more deployable and
capable units, the Army’s transformation plan called for the development of brigade-sized units
called the Interim Force in both the active Army and the Army National Guard. These Interim
Brigade Combat Teams (IBCTs) were the predecessors to the Army’s current Stryker Brigade
Combat Teams (SBCTs).6
General Shinseki’s vision for the FCS was that it would consist of smaller and lighter ground and
air vehicles—manned, unmanned, and robotic—and would employ advanced offensive,
defensive, and communications/information systems to “outsmart and outmaneuver heavier
enemy forces on the battlefield.”7 In order to initiate the FCS program, General Shinseki turned to
the Defense Advanced Research Projects Agency (DARPA), not only because of its proven ability
to manage highly conceptual and scientifically-challenging projects, but also because he
reportedly felt that he would receive a great deal of opposition from senior Army leaders who
advocated heavier and more powerful vehicles such as the M-1 Abrams tank and the M-2 Bradley
infantry fighting vehicle. In May 2000, DARPA awarded four contracts to four industry teams to
develop FCS designs and in March 2002, the Army chose Boeing and Science Applications
International Corporation (SAIC) to serve as the lead systems integrators to oversee certain
aspects of the development of the FCS’s 18 original systems. On May 14, 2003, the Defense
Acquisition Board8 (DAB) approved the FCS’s next acquisition phase and in August 2004 Boeing
and SAIC awarded contracts to 21 companies to design and build its various platforms and
hardware and software.

The Army’s Future Combat System (FCS): Background and Issues for Congress

The FCS Program
Program Overview9
The Army described FCS as a joint (involving the other services) networked “system of systems.”
FCS systems were to be connected by means of an advanced network architecture that would
permit connectivity with other services, situational awareness and understanding, and
synchronized operations that are currently unachievable by Army combat forces. FCS was
intended to network with existing forces, systems currently in development, and systems that
would be developed in the future. The Army intended to field 15 FCS BCTs equipped with new
FCS manned ground vehicles (MGVs) and to provide selected FCS communications, sensor, and
unmanned vehicle technologies to its Infantry Brigade Combat Teams (IBCTs) by FY2025.
DOD’s April 2009 FCS Restructuring Decision
On April 6, 2009, Secretary of Defense Gates announced that he intended to significantly
restructure the FCS program.10 The Department of Defense (DOD) plans to accelerate the spin
out of selected FCS technologies to all brigade combat teams (BCTs) but will recommend
cancelling the manned ground vehicle (MGV) component of the program. The MGV program
was intended to field eight separate tracked combat vehicle variants built on a common chassis
that would eventually replace combat vehicles such as the M-1 Abrams tank, the M-2 Bradley
infantry fighting vehicle, and the M-109 Paladin self-propelled artillery system. Secretary Gates
was concerned that there were significant unanswered questions in the FCS vehicle design
strategy and, despite some adjustments to the MGVs, that they did not adequately reflect the
lessons of counterinsurgency and close quarters combat in Iraq and Afghanistan. Secretary Gates
was also critical that the FCS program did not include a role for Mine-Resistant, Ambush-
Protected (MRAP) vehicles11 that have been used successfully in current conflicts. After re-
evaluating requirements, technology, and approach, DOD will re-launch the Army’s vehicle
modernization program, including a competitive bidding process.
Current FCS Program Status
The Army halted the current FCS program shortly after the completion of a May 2009 Systems of
Systems Preliminary Designed Review. The successor to the FCS program is called the Army
Brigade Combat Team Modernization (ABCTM) program, which will be responsible for
developing and fielding a new ground combat vehicle (GCV) and spinning out remaining FCS
technologies to the Army’s 73 BCTs.12 The FCS program’s lead systems integrators—Boeing and
Science Applications International Corporation (SAIC)—will not be retained for the GCV

program.13 Boeing and SAIC are expected to receive about $350 million in cancellation penalties
due to the decision to discontinue their services as lead systems integrators for the MGV
program.14
Acquisition Decision Memorandum Terminating FCS BCT Program15
On June 23, 2009, Under Secretary of Defense for Acquisition, Technology, and Logistics (USD
AT&L) Ashton B. Carter issued an acquisition decision memorandum (ADM) cancelling the FCS
BCT acquisition program but not the Non-Line-of-Sight Cannon (NLOS-C) Special Interest
Program. In lieu of the FCS BCT Program, the Army was directed to transition to an Army
modernization program consisting of a number of other integrated acquisition programs to
accomplish the following:
• A program to produce and field the first seven Spin-Out Early Infantry Brigade
Combat Team (SO E-IBCT) units sets.
• One or more Major Defense Acquisition Programs (MDAPs)16 to include but not
limited to follow-on BCT modernization to develop, produce, and field-required
unmanned systems, sensors, and networking for the remaining 66 BCTs.
• One MDAP to continue to develop and field an incremental ground tactical
network capability.
• One MDAP to develop ground combat vehicles (GCVs).
The Army is required to brief the USD AT&L on planning for these programs by July 23, 2009.
The Army is also required to identify the impacts of FCS BCT Program cancellation on Army
complimentary systems such as the Joint Tactical Radio System (JTRS) and the Warfighters
Information Network-Tactical (WIN-T) and FCS second-tier efforts such as the Active Protection
System by the end of FY2009.
The Army’s BCT Modernization Strategy17
Pursuant to Secretary Gate’s recommendation to cancel FCS MGVs and the June 23, 2009, ADM
cancelling the FCS BCT Program, the Army devised a tentative BCT modernization strategy.
Some of the key tenets of this strategy are as follows:

16 According to the Defense Acquisition University, in order to be an MDAP, an acquisition program must either be
designated by the USD(AT&L) as an MDAP or estimated by the USD(AT&L) to require an eventual total expenditure
for research, development, test, and evaluation of more than $365 million in FY2000 constant dollars or more than
$2.190B in procurement in FY2000 constant dollars. MDAPs are either Acquisition Category (ACAT) I “D” (for
“Defense Acquisition Board (DAB)” and for which the USD (AT&L) is the Milestone Decision Authority) or ACAT I
“C” (for “Component” and for which the Component/Service Acquisition Executive is the Milestone Decision
Authority).

• Incorporating MRAPs and Uparmored High Mobility, Multi-Wheeled Vehicles
(HMMWVs) into the overall ground vehicle plan and develop a motorized
concept by integrating them into the Infantry Brigade Combat Team (IBCT).
• Preserving FCS Spin Outs and field them to all 73 BCTs along with the FCS
Network by 2025.
• The Training and Doctrine Command (TRADOC) will develop a Ground Combat
Vehicle (GCV) “from a blank sheet of paper” focused on building a versatile
vehicle that incorporates the lessons of the last seven years of war.
• TRADOC will develop the requirement for the GCV, the Network, and a
threshold IBCT with the intention of fielding the GCV in five to seven years
from now.
• The Army will preserve key capabilities once provided by FCS that will no
longer be delivered.
Army leaders are currently planning on delivering a comprehensive review to the Office
of the Secretary of Defense that provides more details on its BCT modernization
strategy—as well as a preliminary design concept for the new GCV—by September 7,
2009.18
Current Ground Combat Vehicle (GCV) Details
While the Army is in the preliminary phases of developing a new concept design for the GCV, a
number of details have emerged during recent congressional testimony and DOD and Army news
conferences that provide some useful insights. Because the Army’s goal is to have the GCV in
production five to seven years, they have indicated that they would rely on existing technologies
and capabilities,19 suggesting that the GCV may be more of a modified “off the shelf” vehicle as
opposed to one “developed from a blank sheet of paper.” It is also possible that the Army might
consider a foreign-produced GCV.20 Army leadership has also indicated that the GCV could be
either a tracked or wheeled vehicle. The Army has also suggested that it sees “a lot of value in
common chassis in terms of logistics support,” and the Army might pursue a common chassis for
GCV variants.21 Other possible GCV features could include a V-shaped hull and side armor to
protect against improvised explosive devices (IEDs).22 Another possible feature for the new GCV
could be fuel efficiency.23 The air transportability of the GCV will also be a key design
consideration and the Army has said that the GCV must be able to fit on C-17 transports.24 The

Chief of Staff of the Army, General George Casey, is said to envision the GCV “first and
foremost, a replacement for the M2/M3 Bradley Fighting Vehicles.”25
FCS Program Budget Issues
FY2010 Budget Request and Savings from the Termination of the Manned
Ground Vehicle (MGV)26

According to the Office of Management and Budget (OMB), the Administration is requesting
$2.981 billion for FCS in FY2010—$633 million less than the FY2009 enacted amount of $3.614
billion. Including the $2.981 billion for FY2010, OMB estimates that the remaining elements of
FCS should cost approximately $24.5 billion through FY2015. OMB has said that the
cancellation of the MGV program will save approximately $22.9 billion.
FY2010 FCS Budget Request Amounts for FCS Programs27
A breakdown of FCS program budget requests for FY2010 is as follows:
• Non-Line-of-Sight Launch System (NLOS-LS): $88.660 million;
• Non-Line-of-Sight Cannon (NLOS-C): $58.216 million;
• FCS Manned Ground Vehicles: $368.557 million;28
• FCS Systems of Systems Engineering & Program Management: $1.067 billion;
• FCS Reconnaissance (UAV) Platforms: $68.701 million;
• FCS Unmanned Ground Vehicles: $125.616 million;
• FCS Unattended Ground Sensors: $26.919 million; and
• FCS Sustainment & Training Research and Development: $749.182 million.

House and Senate Armed Service Committee Markup of FY2010
National Defense Authorization Act (H.R. 2647)

House Armed Services Committee (HASC) Markup29
The HASC recommended fully funding the elements of the original FCS program that will
continue as separate programs in FY2010 at $2.45 billion. The committee further recommended
providing only $100 million, a reduction of $327 million, for the termination of the FCS MGV
program. The committee’s rationale for this decision was that there are unspent FY2009 funds
from the FCS program, and that these funds, plus the $100 million in FY2010 funds, should be
sufficient to cover termination costs. The HASC recommended limiting the number of Spin Out
Early Infantry Brigade Combat Team (SO E-IBCT) equipment sets that can be procured under
low-rate initial production to one brigade set to ensure that the equipment is fully tested before
committing to full-rate production.
Senate Armed Services Committee (SASC) Markup30
The SASC recommends directing the Secretary of Defense to carry out a next-generation ground
combat vehicle program and a next-generation self-propelled howitzer program for the Army and
submit a strategy and plan for these new programs by March 31, 2010. The committee also
recommended reallocating $323.6 million of excess FCS termination liability funds to other
Army research, development, test and evaluation (RDT&E) efforts in support of the GCV
program, including vehicle modernization and survivability research, advanced tank armament
systems, medium and heavy tactical vehicle development, and combat vehicle manufacturing
technology. The SASC also recommended reallocating $58.2 million of excess FCS termination
liability to the Paladin Integration Management (PIM) program to accelerate the upgrade and
modernization of M-109 Paladins. The SASC also recommended supporting the President’s $2.5
billion budget request for RDT&E and procurement funds for further development of the FCS
network and spin-out technologies.

The Army’s Future Combat System (FCS): Background and Issues for Congress

Potential Issues for Congress
MGV Cancellation
If DOD’s proposed cancellation of the MGVs is approved, there are a variety of issues that
Congress might consider. Will the Army be required to extend the useful lives through
recapitalization of combat vehicles that the MGV was intended to replace? What technologies
developed in the MGV program can be incorporated into other programs and what technologies
will be “lost” when the MGV program is terminated? Will the cancellation of the MGV program
also result in the termination or scaling back of the Active Protection System (APS) program?
Will any of the armaments that were under development for various MGV variants, such as the
Lightweight XM360 120 mm cannon, be incorporated into other combat vehicle designs? How
will DOD’s cancellation of the MGV program influence the defense industry in future
endeavors—will developmental costs increase because industry has little confidence that DOD
will remain committed to future ground combat systems programs?
Army BCT Modernization Strategy and Spin Outs
While FCS MGVs are to be terminated, elements of the FCS program such as sensors, unmanned
aerial and ground vehicles, the Non-Line-of-Sight Launch System, and a modified FCS network
will continue on and be incorporated into the Army BCT Modernization Strategy and spin outs.
DOD and the Army has committed to “spinning out” remaining FCS systems and the FCS
Network to all 73 BCTs by 2025. When can Congress expect to see a detailed proposed BCT
modernization strategy and how much does the Army estimate it will cost to modernize all 73
BCTs? Will the Army retain the services of FCS lead systems integrators Boeing and SAIC for
the spin outs and what role, if any, does the Army envision for these firms as part of BCT
modernization? Is it realistic to expect that the BCT modernization program will survive the 15
years that it will take to outfit all 73 BCTs, given poor track record of previous long-term
programs such as Crusader, Comanche, and now the MGV program?
Proposed Ground Combat Vehicles
As part of the Secretary of Defense’s April 2009 decision to restructure the FCS program, the
MGV component was recommended for cancellation. In response, the Army plans to develop a
new Ground Combat Vehicle (GCV) “from a blank sheet of paper” and deliver an initial concept
for this full spectrum vehicle in September 2009. It can be argued that the Army might be rushing
the process to develop the GCV and possibly inviting undue risk and setting the stage for yet
another unfulfilled major vehicle or aircraft acquisition program.
The Army has also pledged that the GCV will be fielded in “5 to 7 years from now.” What
changes will DOD and the Army make in the traditional acquisition process to achieve this goal?
What will be different in the GCV development and procurement process compared to the FCS
MGV development and procurement process? Other possible GCV questions include how many
variations of this new GCV does the Army envision, or is it too early in the conceptual process to
speculate? What current combat vehicles will the GCVs eventually replace? Will the Army cost-
constrain the GCVs (i.e., each version will cost no more than $ X million per vehicle) and other
Congressional Research Service

The Army’s Future Combat System (FCS): Background and Issues for Congress

than C-17 deployable, are there any other deployability constraints that will influence the
development of GCVs?
Non-Line-of-Sight Cannon (NLOS-C) Replacement?
DOD and the Army have also indicated that the congressionally mandated Non-Line-of-Sight
Cannon (NLOS-C) program will also be cancelled, subject to congressional approval. Will the
development of a new self-propelled artillery system to replace the venerable M-109 Paladin fall
under the new GCV program—perhaps as a variant—or does the Army plan to initiate a separate
developmental and procurement effort?
Impact on Operational Concepts and Doctrine
The Army has expended a great deal of intellectual capital and budgetary authority over the past
10 years developing force structure, operational concepts, doctrine, and soldier education and
training predicated on the success of the FCS program in developing and fielding 15 FCS BCTs
and associated support units. In light of the FCS program restructuring, will the Army have to “go
back to the drawing board” in the aforementioned areas as well? If there is a corresponding
requirement to revise force structure, operational concepts, doctrine, and education and training,
is there a plan or “road map” and what are the associated budgetary requirements?

The Army’s Future Combat System (FCS): Background and Issues for Congress

Appendix. Original FCS Subsystems
Manned Ground Vehicles
FCS manned ground vehicles (MGVs) were a family of eight different combat vehicles—with
some having more than one variation—that were based on a common platform and were being
designed to be air transportable by the U.S. Air Force. They were to be equipped with a variety of
passive and active protection systems and sensors that the Army hoped would offer them the
same survivability as the current heavy armor force. In addition the Army intended for its MGVs
to be highly reliable, require low maintenance, and have fuel-efficient engines. The following are
brief descriptions of MGV types and variants that were cancelled in May 2009.32
Mounted Combat System (MCS) (XM1202)
As envisioned, the MCS was to provide direct and beyond-line-of-sight (BLOS) fires, was to be
capable of providing direct fire support to dismounted infantry, and to attack targets with BLOS
fires out to a range of 8 kilometers. The MCS was intended to replace to current M-1 Abrams
tank. The MCS was to have had a crew of two and to be armed with a 120 mm main gun, a .50
caliber machine gun, and a 40 mm automatic grenade launcher.
Infantry Carrier Vehicle (ICV) (XM1206)
As planned, the ICV was to have consisted of four versions: the Company Commander version,
the Platoon Leader version, the Rifle Squad version, and the Weapons Squad version. All four
versions were to have appeared to be identical from the exterior to prevent the targeting of a
specific carrier version. The Rifle Squad version was to have had a two-man crew and able to
transport a nine-man infantry squad and dismount them so that they could conduct combat
operations on foot. The ICV was to have mounted a 30 or 40 mm cannon.
Non-Line-of-Sight Cannon (NLOS-C) (XM1203)
The NLOS-C was to have provided networked, extended-range targeting and precision attack of
both point and area targets with a wide variety of munitions. Its primary purpose was to have
been to provide responsive fires to FCS Combined Arms Battalions and their subordinate units.
The NLOS was to have had a two-man crew and a fully automated handling, loading, and firing
capability.
Non-Line-of-Sight Mortar (NLOS-M) (XM1204)
The NLOS-M was intended to provide indirect fires in support of FCS companies and platoons.
The NLOS-M was to have had a four-man crew, mount a 120mm mortar, and also carry an 81
mm mortar for dismounted operations away from the carrier.

The Army’s Future Combat System (FCS): Background and Issues for Congress

Reconnaissance and Surveillance Vehicle (RSV) (XM1201)
As planned, the RSV was to feature advanced sensors to detect, locate, track, and identify targets
from long ranges under all climatic conditions, both day and night. The RSV was to have had a
mast-mounted long-range, electro-optical infra-red sensor, sensors for radio frequency (RF)
intercept and direction finding as well as a remote chemical warfare agent detector. RSVs were
also to have carried four dismounted scouts, unattended ground sensors (UGS), a Small
Unmanned Ground Vehicle (SUGV) with various payloads, and two Unmanned Aerial Vehicles
(UAVs). In addition to the four scouts, the RSV was to have had a two-man crew and a defensive
weapons system.
Command and Control Vehicle (C2V) (XM1209)
The C2V was intended to serve as the “hub” for battlefield command and control. It was to have
provided information management for the integrated network of communications and sensors for
the FCS brigade combat teams. The C2V was to have had a crew of two and carry four staff
officers and also be capable of employing UAVs.
Medical Vehicle - Evacuation (MV-E) (XM1207) and Medical Vehicle -
Treatment (MV-T) (XM1208)

There were to be two versions of the MV: the MV-E and MV-T. The MV-E would permit combat
trauma specialists to be closer to the casualty’s point of injury as it is to move with combat forces
and evacuate casualties to other treatment facilities. The MV-T was to enhance the ability to
provide Advanced Trauma Management/Advanced Trauma Life Support forward in the battle
area and both MV-E and MV-T would have been capable of conducting medical procedures and
treatments using telemedicine systems. Both would have four-man crews and the capability to
carry four patients.
Field Recovery and Maintenance Vehicle (FRMV) (XM1205)
The FRMV would have been the FCS BCT’s recovery and maintenance system. The FRMV was
to have a crew of three, plus additional space for up to three recovered crew members.
Unmanned Aerial Vehicles (UAVs)33
Each BCT will have a number of UAVs.34 While these UAVs are to provide a variety of
capabilities to forces on the ground, some experts note that they could also present an air space
management challenge to not only manned Army aviation assets, but also to Navy, Marine Corps,
Air Force, and other nation’s aircraft that might be providing support to Army ground operations.
The following are brief descriptions of the Army’s two classes of UAVs:

The Army’s Future Combat System (FCS): Background and Issues for Congress

Class I UAVs (XM156)
Class I UAVs are intended to provide Reconnaissance, Surveillance, and Target Acquisition
(RSTA) at the platoon level. Weighing less than 15 pounds each, these Class I UAVs are intended
to operate in urban and jungle terrain and have a vertical takeoff and landing capability. They are
to be used to observe routes and targets and can provide limited communications transmissions
relay. The Class I UAV are to be controlled by dismounted soldiers and can also be controlled by
selected ground vehicles, and have an endurance of 50 minutes over an 8 kilometer area, and a
10,500 foot maximum ceiling.
Class IV UAVs (XM157)
Class IV UAVs are intended to provide BCT commanders with a long endurance capability. It is
intended to stay aloft for 72 continuous hours and operate over a 75 kilometer radius with a
maximum ceiling of 16,500 feet. It is also planned to interface with other manned and unmanned
aerial vehicles and be able to take off and land without a dedicated airfield.
Unmanned Ground Vehicles (UGVs)35
Armed Robotic Vehicle - Assault Light (ARV- AL) (XM1219)
The ARV was originally intended to come in two variants—the Assault variant and the
Reconnaissance, Surveillance, and Target Acquisition (RSTA) variant. The RSTA variant has
been deferred as part of the Army’s 2007 FCS program restructuring. The two variants were to
share a common chassis. The Assault Light variant is to provide remote reconnaissance capability,
deploy sensors, and employ its direct fire weapons and special munitions at targets such as
buildings, bunkers, and tunnels. It is also intended to be able to conduct battle damage
assessments, act as a communications relay, and support both mounted and dismounted forces
with direct and anti-tank fire as well as occupy key terrain.
Small Unmanned Ground Vehicle (SUGV) (XM1216)
The SUGV is a small, lightweight, manportable UGV capable of operating in urban terrain,
tunnels, and caves. The SUGV will weigh 30 pounds, operate for 6 hours without a battery
recharge, and have a one kilometer ground range and a 200 meter tunnel range. Its modular
design will permit a variety of payloads which will enable it to perform high-risk intelligence,
surveillance, and reconnaissance (ISR) missions, and chemical weapons or toxic industrial
chemical reconnaissance.
Multifunctional Utility/Logistics and Equipment Vehicle (MULE)
The MULE is a UGV that will support dismounted infantry. It is to come in two variants sharing a
common chassis—a transport variant (XM1217) and a countermine variant (XM1218). The
transport variant is to be able to carry 1,900 to 2,400 pounds of equipment and rucksacks for

dismounted infantry and follow them in complex and rough terrain. The countermine variant is to
have the capability to detect, mark, and neutralize anti-tank mines.
Unattended Ground Sensors (UGS)36
UGS are divided into two groups—Tactical UGS and Urban UGS—and are described as follows:
Tactical UGS (AN/GSR-10)
Tactical UGS include intelligence, surveillance, and reconnaissance (ISR) sensors and Chemical,
Biological, Radiological, and Nuclear (CBRN) sensors. These sensors are to employ a variety of
sensing technologies and integrated into the overall network. They are intended to be deployed by
hand, by vehicle, or by robot and have a 48 hour endurance. They are intended to be expendable,
low-cost sensors used for such tasks as perimeter defense, surveillance, target acquisition, and
CBRN early warning.
Urban UGS (AN/GSR-9)
Urban UGS can also be employed by soldiers, vehicles, or robots and are intended to provide
situation awareness inside and outside of buildings for force protection and also for previously
cleared buildings and areas.
Non-Line-of-Sight Launch System (NLOS-LS) (XM501)
NLOS-LS is to consist of missiles in a deployable, platform-independent, container launch unit
(CLU), which can be fired in an unmanned and remote mode. Each CLU is to have a fire control
system and 15 missiles consisting of Precision Attack Missiles (PAM).
The PAM is to have two employment modes—a direct-fire and a fast attack mode or a boost-glide
mode. The missile is intended to receive target information prior to launch and receive and
respond to target location updates while in flight. The PAM can be fired in the laser-designated
mode and transmit near real-time target imagery prior to impact.
The Network37
The FCS network program will continue but will likely be significantly modified because of the
cancellation of the MGVs. The original FCS network was to have consisted of four interactive
components—the System-of-Systems Common Operating Environment (SOSCOE); Battle
Command (BC) software; communications and computers (CC); and intelligence, reconnaissance
and surveillance (ISR) systems.

System-of-Systems Common Operating Environment (SOSCOE)
The SOSCOE is to enable the integration of a variety of software packages into the network. It is
intended to use commercial, off-the-shelf hardware and allow for the integration of critical
interoperability packages that translate Army, Navy, Air Force, Marine Corps, and allied message
formats into internal message formats.
Battle Command (BC) Software
Battle Command mission applications are to include mission planning and preparation, situational
understanding, battle command and mission execution, and warfighter-machine interface.
Mission Planning and Preparation
Consists of 16 different functions that provide units with the following automated capabilities:
• The development of deliberate, anticipatory, and rapid-response plans;
• The ability to perform plan assessments and evaluations;
• The ability to perform terrain analysis;
• The conduct of mission rehearsals; and
• The conduct of after action reviews.
Situational Understanding
This consists of 10 different packages that allow the user to better comprehend his surroundings.
These packages employ map information and a variety of databases that help to determine enemy
locations and capabilities, infer enemy intentions, and assess the threat to U.S. forces.
Battle Command and Execution
This package contains a variety of planning and decision aids to help commanders make rapid,
informed, and accurate decisions during battle. These packages can also be used in the training
and rehearsal modes.
Warfighter-Machine Interface Package
This package receives soldier-generated information and displays information across all FCS
platforms for soldier use.
Communications and Computer (CC) Systems
The Communications and Computer network is intended to provide secure, reliable access to
information over extended distances and complex terrain. This network is not intended to rely on
a large and separate infrastructure because it is to be embedded in combat vehicles and move with
the combat units. The communications network is to consist of a variety of systems such as the
Joint Tactical Radio System (JTRS); Wideband Network Waveform and Soldier Radio Waveform

systems; Network Data Link; and the Warfighter Information Network Tactical
(WIN-T).
Intelligence, Reconnaissance and Surveillance (ISR) Systems
The Intelligence, Reconnaissance and Surveillance System is to be a distributed and networked
array of multispectral ISR sensors intended to provide timely and accurate situational awareness
to the force. In addition, the ISR system is intended to help formations avoid enemy fires while
providing precision, networked fires to the unit.
