A. Mission Description and Budget Item Justification

This Program Element (PE) supports the design, development, acquisition, integration and fielding of realistic mobile threat simulators and realistic threat simulation products utilized in Army/Department of War (DoW) test and evaluation (T&E) and developmental and operational tests. This PE originally funded simulators representing Soviet equipment, but scope was expanded to address emerging world threats. Army Threat Simulator and Threat Simulation products are utilized to populate test battlefields for United States (U.S.) Army Test and Evaluation Command (ATEC), to conduct developmental and operational tests, and to support Capability Program Executive Simulation, Training, Test and Threat (CPE ST3) (formerly Program Executive Office for Simulation, Training and Instrumentation (PEO STRI)) required user testing in System Integration Laboratories (SILs) and hardware/simulation in-the-loop facilities. These battlefield simulators represent adversary systems (e.g. missile systems, command, control and communications systems, electronic warfare systems, etc.) in order to portray a realistic threat environment during testing of U.S. weapon systems.

Army Threat Simulator and Threat Simulation products developed or fielded under this PE support Army-wide, non-system-specific threat product requirements. Each capability is pursued in concert and coordination with existing Army/DoW and Tri-Service capabilities to eliminate duplication of effort. Simulator development is responsive to Office of the Secretary of War and Government Accountability Office guidance for the Army to conduct operational testing in a realistic threat environment. Actual threat equipment is acquired when appropriate (in lieu of development) and total package fielding is still required (i.e., instrumentation, operations and maintenance, manuals, new equipment training, etc.). Threat simulator development is accomplished under the auspices of the Project Manager for Cyber Test and Training (PM CT2) and the Director, Operational Test and Evaluation (DOT&E) Threat Simulator Investment Working Group.

This funding line supports testing of Army Modernization Priority Programs.

A. Mission Description and Budget Item Justification

This project supports the design, development, acquisition, integration, and fielding of realistic mobile threat simulators and realistic threat simulation products utilized

in Army/Department of War test and evaluation and developmental and operational tests. This project originally funded simulators representing Soviet equipment, but

scope was expanded to address emerging world threats. Army Threat Simulator and Threat Simulation products are utilized to simulate operational environments and

populate test battlefields for the United States Army Test and Evaluation Command, to conduct developmental and operational tests, and to support Capability Program

Executive Simulation, Training, Test and Threat (CPE ST3) (formerly Program Executive Office for Simulation, Training and Instrumentation) required user testing in

System Integration Laboratories and hardware/simulation in-the-loop facilities. These operational environment and battlefield simulators represent adversary systems

(e.g. intelligence, surveillance and reconnaissance, missile systems, command, control and communication systems, electronic warfare systems, etc.) in order to portray a realistic full-spectrum threat environment during testing of U.S. weapon systems. Base funding will establish enterprise level business processes and services to develop, operate, and secure air and ground testing capabilities in accordance with OSW and Army Digital Engineering and Software Modernization Strategies. Efforts will promote synergies between the training and testing enablers to improve product development, integration, and cyber activities, and to promote re-use of common assets and services to meet Army modernization priorities.

Information and Decision Advantage Threat Simulation: Supports Army's capability and capacity to provide realistic information dimension threat representative across the conflict continuum. Threat realism focuses on the adversary's ability to sense, collect, analyze and act upon Army critical information or critical program information.

Army Threat Simulator and Threat Simulation products developed or fielded under this project support Army-wide, non-system-specific threat product requirements. Each capability is pursued in concert and coordination with existing Army/DoW and Tri-Service capabilities to eliminate duplication of effort. Simulator development is responsive to Office of the Secretary of War and Government Accountability Office guidance for the Army to conduct operational testing in a realistic threat environment. Actual threat equipment is acquired when appropriate (in lieu of development) and total package fielding is still required (i.e., instrumentation, operations and maintenance, manuals, new equipment training, etc.) Threat simulator development is accomplished under the auspices of the Project Manager for Cyber Test and Training and the Director, Operational Test and Evaluation Threat Simulator Investment Working Group.

Defined Radar (SDRadar) represents new challenges in radar technology given the possibility of performing basic operations (i.e. mixing, filtering, modulation, and demodulation) by simply employing software modules to eliminate much of the radar specific processing hardware. The main goal of a software defined approach is related not only to a clear cost reduction, but also to a significant increase of the versatility of the system, since signal generation and signal processing parameters may be easily adapted to the task under consideration. Integration into test and training range and Home Station networks, such as the Threat Battle Command Force (TBCF), provides significant Integrated Air Defense Systems (IADS) capability utilizing multiple units. This program supports US Army acquisition ability to adequately stress weapon systems undergoing both Developmental and Operational Tests, as well as Live, Virtual, and Constructive (LVC) training. The low-cost systems emulate known threat radars across multiple radar bands and develop as many emitters as possible to create a dense, RF environment. FY 2026 Plans: Provide additional Ku and Ka-band threat radar emitters to support Developmental and Operational Tests across multiple Army Test and Training programs. These radar emitters will support the Army Test and Evaluation Center threat priorities in support of the US Army major acquisition testing efforts. Develop Time Space Position Information interface requirements that will permit the tracking of targets in real-time to support developmental and operational tests as well as training exercises. FY 2027 Plans: FY 2027 funds will provide additional Ku and Ka band threat radar emitters to support Developmental and Operational Tests across multiple Army Test and Training programs. Continue development on Electronic Attack waveforms to ensure that systems can be used in multiple vignettes. Begin development on prototype Ka band Active Electronically Scanned Array (AESA) antenna to support LPI/LPD radar waveforms. Continue to support Army Test and Evaluation priorities for upcoming test events. Continue to develop the interface to the Tactical Application Kit (TAK) in support of remote operations and advanced command and control. FY 2026 to FY 2027 Increase/Decrease Statement: FY 2026 to FY 2027 funding increase will continue development on Electronic Attack waveforms.

A. Mission Description and Budget Item Justification

This Project funds improvement and modernization (I&M) for the Ronald Reagan Ballistic Missile Defense Test Site (RTS) instrumentation systems. The Reagan Test

Site with its remote location and one of kind instrumentation systems provides a strategic test environment that cannot be replicated. In order to continue its critical

mission of testing missile systems that are of paramount importance to the defense of the nation, the RTS instrumentation systems must be continuously updated

and upgraded to support the emerging technologies being developed by the Department of War (DOW) such as hypersonics and other advanced weapons systems.

Without modernization, these instrumentation systems face obsolescence or degraded capability and the inability to provide the critical data needed for continued

materiel development. Without instrumentation on par with the technologies being utilized in emerging systems, the materiel developer will be unable to complete their

test programs or pass programmatic milestones toward deployment. These funds provide modernization of the radar, telemetry, optics, range safety, communications,

command/control and other equipment essential to meet test and evaluation requirements of the Services and DoW agencies. The RTS instrumentation is required

to support data collection for test & evaluation assessments and operational decisions that have strategic implications for the Army, Navy, Air Force, United States

Strategic Command (STRATCOM), Missile Defense Agency (MDA), Defense Advanced Research Projects Agency (DARPA), National Aeronautics and Space

Administration (NASA), and other customers. RTS, located in the Republic of the Marshall Islands, is a remote, secure activity of the Major Range and Test Facility Base

(MRTFB). Funding will enable RTS to meet National Defense objectives and sustain the required instrumentation suite.

A. Mission Description and Budget Item Justification

This project funds the development, acquisition, and integration of major operational test instrumentation for the U.S. Army Test and Evaluation Command's Operational

Test Command and supporting test activities at test and training ranges. Requirements for instrumentation are identified through a long-range survey of project

managers, Research Development and Engineering Centers (RDECs), and Battle Laboratories developing future weapon systems and the test programs that support

these systems. Project focus is to address Director Operational Test and Evaluation (DOT&E) identified Army test realism shortfalls. Base funding will establish

enterprise level business processes and services for test instrumentation to develop, operate, and secure capabilities in accordance with OSW and Army Digital

Engineering and Software Modernization Strategies. Efforts will promote synergies between the training and testing enablers to improve product development,

integration, and cyber activities, and to promote re-use of common assets and services to meet Army modernization priorities.

Projects are designated as a major test program based on their visibility, assessed relative technical risk (medium-high), schedule risk, cost (greater than $1.500 million per year or $7.500 million for the total project) and applicability to other mission areas or services. These projects are technically demanding, state-of-the-art, unique instrumentation assets or suites to meet technology shortfalls, and generally result from development programs managed by a professional project management team.

The DOT&E annual report to Congress identified shortfalls in the Army's abilities to create realistic operational environments. The Expeditionary Live Virtual Constructive Command Center (XLCC) project addresses multiple shortfalls identified by DOT&E. XLCC is a portfolio of related development efforts that will deliver a system of systems to provide Test Monitoring & Control (TMC) for the Common Operating Picture (COP) for Exercise Control (EXCON) for the Multi-Domain Operations Environment (MDOE). XLCC will provide Real Time Casualty Assessment (RTCA) and instrumentation suite that delivers a high fidelity, realistic, real-time capability to measure the System Under Test (SUT). XLCC also allows the U.S. Army to test all Current-to-Future weapon systems in a realistic Future Operating Environment (FOE). XLCC will transition Research, Development, Test and Evaluation (RDTE) performance enhancements and technology upgrades to the Operational Test Command to include control, communications, communications network, weapons system interfaces, vehicle and dismounted-troop kits and peripherals. XLCC will enable sufficient data collection and analysis tools to collect, store and analyze Decision Driven Data (DDD). Improvements will enable the XLCC system of systems to measure and record accrued battle damage assessment (BDA), levels of exposure, effects of countermeasures, evasive action, and instrument threat vehicles for effect After Action Reviews (AAR). This capability is required by the operational test community to create an adequately realistic representation of a MDO combat environment across all Signature Modernization Efforts to support Army modernization priorities and other operational tests.

A. Mission Description and Budget Item Justification

In order to effect strategic overmatch on current and future battlefields, it is essential that the United States (U.S.) Army provide advanced radar system instrumentation

for developmental testing. Since existing range radar instrumentation is aged beyond useful life and cannot adequately support emerging test requirements, the Range

Radar Replacement Program (RRRP) recapitalizes and develops modern instrumentation radars to replace obsolete tracking and surveillance radars at U.S. Army Test

and Evaluation Command's (ATEC) activities, which include: Aberdeen Test Center (ATC), MD; White Sands Test Center (WSTC), NM; and Yuma Test Center (YTC),

AZ. RRRP will deliver capability in three (3) block increments: Block I will recapitalize or replace existing radar systems, Block II will develop a Long Range Radar (LRR)

which is compliant with ATEC's Test Capability Requirements Document (TCRD), and Block III will develop LRRs and Medium Range Radars (MRRs) to meet ATEC

Block III TCRD Addendum. The acquisition of modern instrumentation radar systems will provide the Army with critical testing data essential for the development of next

generation technology and advanced system capabilities. The RRRP provides the test centers with improved radar resolution, sensitivity, accuracy, clutter suppression,

and reliability. The planned solution to meet program requirements consists of four primary items: Long Range Single Object Tracking Radars (SOTR), Long Range

Multiple Object Tracking Radars (MOTR), Medium Range Radars (MRR), and Short-Range Radars (SRR). The resulting systems will not only reduce operation and

sustainment costs for the ranges, but will improve data collection, thus enhancing development of Army systems being tested at these ranges. The current fleet of

instrumentation radars located at ATC, WSTC, and YTC has become antiquated to the extent that they are not able to support the test needs of the test centers.

FY27 funds in the amount of $48.853 Million provides funding for acceptance testing of Block I instrumentation radars, continued development and acceptance testing of the Block II Long Range Instrumentation Radar prototype, and allows for continued development of Block III prototype radars.

A. Mission Description and Budget Item Justification

In 2016 the Army Acquisition Executive (AAE) designated the Program Manager for Cyber, and Training (PM CT2) as the Office of Primary Responsibility for Cyber

Acquisition Blue Teams (CABT) certifications and standards program. This Project executes the establishment and management of certification standards for CABT and

coordination of requirements on behalf of the Assistant Secretary of the Army for Acquisition, Logistics, and Technology (ASA (ALT)).

PM CT2 will establish certification standards, certify Blue Teams, and maintain a vulnerabilities/lessons learned repository. PM CT2 will work with Blue and Red Teams to establish processes which facilitate open network tests under the red team authority, coordinate with Program Managers on CABT efforts on behalf of ASA(ALT) and report to ASA(ALT) on new cyber vulnerabilities. Blue teams will work cooperatively with acquisition programs to make sure all security measures are taken throughout the program's lifecycle, ensuring cyber resiliency. Blue teams are essential to help military operators assess, protect and defeat the presence of cyber security threats across Army Acquisition Programs.

Will focus on the continuation of certifying candidate teams. The goal is to certify enough teams to allow acquisition programs the flexibility to find a certified Blue Team that meet their program's schedule and cost and can be incorporated early on in the program. CABT vulnerability assessments will provide data analytics to report trends and lessons learned. A web portal will serve as a one-stop shop for both candidate and certified Blue teams to obtain and maintain their certification.

A. Mission Description and Budget Item Justification

This Program Element (PE) is unique within the Research, Development, Test & Evaluation (RDT&E) portfolio because it funds base operation so that the RTR and other mission partner can do the full spectrum of test, evaluation, space surveillance, and mission support activities at U.S. Army Garrison-Kwajalein Atoll (USAG KA). The PE directly supports operations across 11 leased islands equipped with radars, telemetry systems, and optical instrumentation that enable continuous New Foreign Launch surveillance, space surveillance, space object identification, and offensive and defensive strategic missile and interceptor testing. The PE also provides the logistics, infrastructure, and municipal services required to sustain a strategically critical mission platform located 2,300 miles southwest of Hawaii and supporting all permanently assigned military and government personnel.

Kwajalein Atoll's unique electromagnetic spectrum environment, equatorial position, deep-water geography, and world class instrumentation make it an irreplaceable national asset for space and missile operations. The Ronald Reagan Space and Missile Test Range (RTR), located on Kwajalein, is the Department of War's only land impact missile test range and provides an increasingly vital Test & Evaluation (T&E) capability for current and emerging strategic systems.

The U.S. Army Kwajalein Atoll / Ronald Reagan Space and Missile Test Range (USAKA/RTR), located in the Republic of the Marshall Islands, is a remote, secure component of the Major Range and Test Facility Base (MRTFB). USAKA/RTR conducts test and evaluation for major Army and DoW missile and space acquisition programs and delivers New Foreign Launch surveillance and space operations-including surveillance and object identification-in support of U.S. Strategic Command (USSTRATCOM), the U.S. Air Force, and National Aeronautics and Space Administration (NASA) scientific and space missions.

A. Mission Description and Budget Item Justification

The Army Concepts Experimentation Program supports current and future concepts and capabilities involving Soldiers and Leaders within live, virtual, and constructive

environments by exploring concepts, capability requirements and solutions across Doctrine, Organization, Training, Materiel, Leadership and Education, personnel,

and Facilities (DOTMLPF) domains. The purpose of Concepts Experimentation is to clarify and mitigate risk for current and future forces. Experiments and projects

inform Army futures concepts and assess high-risk conceptual assumptions in order to focus required capabilities and represent user requirements in the future Army,

to field the Army. Army experiments use the combined resources of Army Battle Laboratories, operational units, research labs, materiel developers, concept developers,

industry and academia to collaborate in the development, refinement, and assessment of future force concepts. Simulated Experiments (SIMEX) will integrate and

assess Army Concepts and Force Design phases with Army-level issues across the breadth of a campaign that highlights validation and integration of MDO capabilities.

This Program Element (PE) enhances Joint Capabilities Integration and Development System (JCIDS) development in support of Program Executive Offices (PEOs) and Program Managers (PMs) for acquisition milestone decisions. Funding ensures AFC/FCC serves as the voice of the warfighter and compliments the materiel developer in providing total capability management ensuring the integration of DOTMLPF solutions. This PE resources the Army's Continuous Learning Campaign, currently known as Project Convergence (PC). PC is the Army's campaign of learning based on a continuous, structured series of demonstrations and experiments, designed to aggressively advance and integrate our Army's contributions to Joint Force overmatch. It ensures the Army, as part of the Joint fight, can rapidly and continuously integrate or "converge" effects across all domains to overmatch our adversaries in competition and conflict. PC is part of the Army's intent to achieve a full Multi-Domain Operations (MDO) capability. Capstone is the periodic, joint, multinational experiment within Project Convergence that pulls together concepts, technology, gaps, and requirements at scale for the Army and applies them to the Indo-Pacific and European theaters. Capstone experiments on ways to defeat our pacing threat in the Indo-Pacific and the five key functions the Army performs in this theater: building and defending bases, command and control for Combined Joint Force (CJF), sustaining logistical supply lines, defensive fires through long-range precision strikes, and counter-attack forces. In addition, Capstone experiments against near-peer adversaries in the European theater, against which the CJF demonstrates pulsed operations to enable a land-centric exploitation. Capstone focuses on Army with the immediate need to integrate select technologies to keep the Army ahead of our peers and on the leading edge of development. This PE provides funding for Defender, Forager. These experiments help the Army evaluate emerging concepts, new formations, integrate new technologies, and promote interoperability between the Army, other services and multinational partners.

The Soldier-Centered Analysis Future Force Project (33B) will provide early application of human performance and human figure modeling tools in the development of Soldier-focused requirements to shape technology for Future Force development. These efforts include design analyses, constructive simulations, and Soldier-in-the

A. Mission Description and Budget Item Justification

This project provides funding for the West Desert Test Center (WDTC) and U.S. Army Combat Capabilities Development Command (DEVCOM) Chemical Biological

Center (CBC) Bio-Testing Division (BTD-CBC) MRTFB institutional technical and operational capability for testing DoW Chemical and Biological (CB) and Non-

Traditional Agent (NTA) defense materiel, equipment, and systems from concept through production to include associated special operations Tactics, Techniques, and

Procedures Development (TTPD) activities.

Efforts included in this project are:

(1) BTD-CBC: Beginning in FY25, the BTD-CBC name changed to DEVCOM CBC Dugway. This effort sustains a critical Test and Evaluation (T&E) resource essential to fulfilling the 2021 Army Biological Defense Strategy's purpose: "to maintain the Army's capability and capacity to accomplish its mission and ensure readiness in the face of biological threats and hazards, in support of the Department of War (DoW) and the Nation." By preserving this T&E resource, the Army and DoW are better prepared to address the challenges of operating effectively in biologically contested environments, ensuring mission success and safeguarding national security.

(2) WDTC: Beginning in FY27, the WDTC funding moved from the WD1 project code to the F30 project code.

Together WDTC and DEVCOM CBC Dugway are the reliance centers for all DoW CB defense testing and provide the United States' only combined range, chamber, toxic chemical lab, and bio-safety level 3 Biological Select Agent and Toxin (BSAT) aerosol test capability. This project funds the institutional and overhead costs to operate WDTC and DEVCOM CBC Dugway in compliance with the National Defense Authorization Act (NDAA) for FY03 (Public Law 107-314), Section 232, "Objective for institutional funding of test and evaluation facilities." Those costs that are directly attributable to the use of WDTC and DEVCOM CBC Dugway for testing and TTPD activities under a particular program, over and above the institutional and overhead costs, are billed to the program.

WDTC and DEVCOM CBC Dugway use unique, state-of-the-art chemical and life-science test facilities and test chambers to perform CB defense testing of protective gear, decontamination systems, detectors, equipment, and non-materiel CB defense solutions while maintaining safety, security, and surety of chemical agents and biological pathogens. WDTC also provides surveyed and instrumented outdoor ranges and specialized structures for CB simulant agent dissemination in operationally threat- relevant environments and TTPD activities.

A. Mission Description and Budget Item Justification

This Program Element (PE) funds objective vulnerability assessment products necessary for the inherently-governmental Army Test & Evaluation Command/Army

Evaluation Center (ATEC/ AEC) mission and for the Rresearch and development and analysis communities. Products result from investigating, analyzing, assessing,

experimenting and reporting on the survivability of Soldiers, and on the survivability, lethality and vulnerability (SLV) of the highest-priority Army and threat systems.

Products are leveraged within the Transformation & Training Command (T2COM), the Futures and Concepts Command (FCC), and Portfolio Acquisition Executives

(PAEs) to exercise constructive design influence over materiel development and to provide credible engineering-level underpinning and input to the Army analytical

community.

This PE provides quantitative analyses and data for fielded and developmental systems as the Army pursues its modernization priorities and ensures readiness through the fielding of lethal and survivable systems for multi-domain operations. This PE funds engineering level analysis and experimentation supporting all PAEs including Fires, Command and Control (C2)/counter-C2, Maneuver Ground, Maneuver Air, Agile Sustainment and Ammunition, and Layered Protection & Chemical, Biological, Radiological & Nuclear (CBRN) and other Army priorities. Principal data and analysis domains are integrated materiel performance, cyber resilience, human engineering and performance, Electromagnetic Warfare (EW) threat defense, and mission threat analysis.

Assessments funded by this PE are conducted across the spectrum of multi-domain battlefield threats to include: guns, missiles, mines and other methods of inflicting physical damage; jammers, countermeasures, and other electronic warfare techniques; cyber threats from insiders to nation states; and directed energy weapons. Many different kinds of technical capabilities are used to generate these analyses, including specialized equipment, modeling & simulation, and experimental facilities. This PE ensures these capabilities can represent a live, virtual, or constructive hostile environment required for credible assessment, thus enabling evaluators, developers, users, and decision makers to make informed acquisition judgments. The technical data from earliest T2COM/FCC experimentation through developmental testing and final operational test is retained and serves as T2COM's repository of analysis and information for supporting an ever-improving body of evidence to drive milestone decisions. This body of evidence enables properly informed decisions concerning acquisition and production; maximizes Army overmatch in systems and tactics; informs investment priorities; and mitigates system weaknesses prior to actual combat.

Technical data and analysis results funded by this PE are efficiently leveraged for many different Army uses, reducing total cost to the Army by eliminating the need for duplicative capabilities funded by individual system developers. Central funding of this mission assures accurate and consistent technical treatment across all formal system Evaluations, and across the Army's analytical community as it conducts analyses of alternatives and other studies. The United States (U.S.) Army Combat Capabilities Development Command (DEVCOM) and ATEC/AEC integrate the results from the work program into Army's formal evaluation process to ensure ATEC can comply with its legally-mandated responsibility to assess system survivability, lethality and vulnerability (SLV) along with effectiveness and suitability.

A. Mission Description and Budget Item Justification

This project funds objective survivability, lethality and vulnerability (SLV) analyses necessary for Army Senior Leader decision-making. Products result from investigating,

analyzing, assessing, experimenting and reporting on the survivability of Soldiers, and on the SLV of the highest priority Army and threat systems. Products are used to

exercise constructive design influence over materiel development and to provide credible engineering-level underpinning and input to the Army's analytical and test &

evaluation communities.

This project provides quantitative analyses and data for fielded and developmental systems as the Army pursues its modernization priorities and ensures readiness through the fielding of lethal and survivable systems for all-domain operations. This Project funds engineering level analysis and experimentation to analyze system performance in critical technology areas, including aviation, ground vehicle and protection technologies, communications, command and control (C3), autonomy, unmanned aerial systems (UAS) and counter UAS, sensing and intelligence, energetics/fires, assured positioning, navigation and timing (A-PNT), propulsion, power and energy, and other Army priorities. Principal data and analysis domains are system performance, cyber resilience, human systems integration (HSI), electromagnetic warfare (EW) threat defense, ballistic lethality and vulnerability, and mission threat analysis.

Analyses funded by this project are conducted across the spectrum of battlefield threats to include: guns, missiles, mines and other methods of inflicting physical damage; jammers, countermeasures, and other EW techniques; cyber threats from insiders to nation states; and directed energy weapons. Many different kinds of technical capabilities are used to generate these analyses, including specialized equipment, modeling & simulation (M&S), and experimental facilities. This project ensures these capabilities can represent a live, virtual, and constructive hostile environment required for credible analysis, thus enabling decision makers to make informed acquisition judgments. This technical data from earliest experimentation to fielding is retained and serves as the Army's authoritative source of system performance analysis information for supporting an ever-improving body of evidence to drive milestone decisions. This body of evidence enables properly informed decisions concerning acquisition, design/development and production; maximizes Army overmatch in systems and tactics; informs investment priorities; and mitigates system weaknesses prior to actual combat.

Technical data and analysis results funded by this project are efficiently used for many different Army decisions, reducing total cost to the Army by eliminating the need for duplicative capabilities funded by individual system developers. Central funding of this mission assures accurate and consistent technical treatment across all formal system evaluations, and across the Army's analytical community as it conducts analyses of alternatives and other studies. The analyses and M&S serve to supplement and augment test data, reduce testing costs and increase evaluation confidence in the survivability and lethality performance of Army systems.

A. Mission Description and Budget Item Justification

This Program Element (PE) resources the U.S. Army Futures and Concepts Command (FCC) Transformation Decision Analysis Center (TDAC) to conduct integrated

materiel performance analyses to support Army decisions in technology, materiel acquisition, and the design, development, fielding and sustainment of Army materiel

systems. The analysis products funded by this PE are leveraged to support acquisition decisions and influence the design, development, and sustainment of Army

weapon/materiel systems in support of the current and future force in Portfolio Acquisition Executive (PAE) areas of Fires, Command and Control (C2) and counter-C2,

Maneuver Gound, Maneuver Air, Agile Sustainment & Ammunition, Layered Protection & Chemical, Biological, Radiological and Nuclear (CBRN), and other Army priority

efforts.

As the Army's center for integrated materiel performance analysis, the TDAC supports Army and Department of War (DoW) decision makers throughout the entire acquisition process in responding to analytical requirements across the full spectrum of materiel. The TDAC's unique in-house, consistent, integrated analytical capability provides the Transformation & Training Command (T2COM) and Army leadership with timely, independent, unbiased, reliable, and high quality analysis to support complex decisions required for current operations and the development of the Future Force. The TDAC's integrated set of skills, tools, and data repository are focused on the highest Army priorities with a core mission to build the body of evidence and deliver objective analysis and experimentation across the entire life cycle to ensure readiness today and a more lethal future force tomorrow.

This PE develops and certifies system level, and systems-of-systems level, performance and effectiveness data across a broad range of capabilities such as target acquisition, probability of inflicting catastrophic damage, personnel and vehicle survivability, mobility, network, system reliability, and additional capability areas used in Army studies. The PE funds the development of item-level performance methodology, and Models and Simulations (M&S) for the current and future operational environments and emerging threats. The M&S capabilities support the development, linkage and accreditation of live, virtual, and constructive simulations, and provide unique tools that support systems analysis of individual systems and the combined arms environment. This M&S infrastructure provides a hierarchical modeling framework that is unique to the TDAC and enables a comprehensive performance and effectiveness analysis and prediction capability that can be utilized to support trade-off and investment decisions prior to extensive and expensive hardware testing of proposed systems/technologies.

This PE funds the Center for Reliability Growth (CRG), to develop critical tools, methodologies, policies, guidance and educational materials required to help systems improve and achieve required reliability during the acquisition process. The CRG develops and applies engineering approaches to assess the reliability of Army materiel and provides recommendations on ways to improve reliability, thereby, reducing logistics footprints and life cycle costs, and extending failure-free periods for materiel. The CRG has developed an integrated set of skills and tools focused on its core competencies to be responsive in delivering objective data and analysis across the entire life cycle to ensure readiness today and a more lethal future force tomorrow.

A. Mission Description and Budget Item Justification

This project provides funding to the Army Test and Evaluation Command (ATEC) to operate the Operational Test Command (OTC) which conducts independent

operational tests that provide significant data to Army decision makers on key systems in support of the Army's transformation priorities. These operational tests are

required by public law (Title 10 USC 2399). This project finances recurring costs for OTC that are essential to conduct realistic and continuous testing in the critical areas

of equipment, doctrine, force design and training. These recurring costs include civilian pay, requirements for test support contracts, sustainment of test technology,

network support, training, supplies, equipment, and temporary duty travel.

OTC consists of four forward Test Directorates (Airborne and Special Operations Test Directorate, Fort Bragg, North Carolina; Air and Missile Defense Test Directorate, Fort Bliss, Texas; Fires Support Test Directorate, Fort Sill, Oklahoma; and the Intelligence Electronic Warfare Test Directorate, Fort Huachuca, Arizona) together with four additional Test Directorates (Aviation; Maneuver; Mission Command; Maneuver Support and Sustainment) and OTC Headquarters at Fort Cavazos, Texas. These activities support the development and fielding cycle of all Army acquisition programs including rapid fielding initiatives in support of the Army's Transformation Initiatives. The primary mission of these test directorates is to perform detailed planning, execution, and reporting of Customer Tests, Early User Tests, Limited User Tests (LUT), Initial Operational Test and Evaluation (IOTE), and Follow-On Operational Tests (FOT) in support of the Army's Signature Transformation Efforts. OTC also supports Army Futures Command's Soldier Touch Points and other early assessments of potential new systems the Army seeks to acquire in support of Army transformation. Funding provides essential sustainment of models, simulations, and instrumentation for operational testing of airborne/aviation systems, mission command systems, fires systems, intelligence systems, real-time casualty assessment (RTCA), and common live-virtual-constructive (LVC) tools.

A. Mission Description and Budget Item Justification

This Program Element (PE) promotes the Army's Modeling and Simulation (M&S) strategy, defined by five guiding priorities: (1) formulate Army M&S policies; (2) develop and employ management processes for models, simulations and data; (3) develop M&S standards, architectures, networks and environments; (4) develop/ employ new M&S tools and simulation technology; (5) develop an M&S workforce. Specifically, this PE focuses on priorities 3 and 4 to include the modernization of the Center for Army Analysis (CAA) models, simulations, and analytic capabilities.

M&S Standards, Architectures, Networks and Environments: The consistent use of standards, architectures, networks and environments advances the goal of interoperability. The Army coordinates with Joint, Interagency, Intergovernmental, and Multinational (JIIM) partners along with industry and academia to develop/employ standards that promote collaboration and facilitate the sharing of tools, data and information. The Army oversees procedures and processes for the appropriate use of standards to foster common formats and increase M&S and data reuse. The Army ensures these standards, architectures, networks and environments are readily accessible and can be reliably applied by users.

M&S Tools and Simulation Technology: The Army must have credible M&S tools and data to support the full range of Army organizational missions and functional responsibilities. M&S results that are timely and credible enhance decision making. The Army must develop and accredit reliable M&S tools so that decision makers and senior leaders benefit from the results and thus support the continued development, integration and use of such tools. To ensure credibility and reliability of results, M&S managers, developers and users must make the capabilities, constraints, limitations and assumptions of their M&S tools readily accessible. PE 0605718A provides for the development and employment of tools in the form of models, simulations and data that support the full range of Army missions and deliver timely information to Army senior leaders. Moreover, these tools can be documented, verified, validated and accredited for their intended purpose in order to provide timely, credible results.

This program element supports modernization of the analytic tools utilized by Center for Army Analysis. CAA conducts analysis of senior-level decisions for current and future national security issues. The suite of models, simulations, and analytic tools must remain relevant, current, and responsive to the ever-changing Operational Environment in order to support effectively the Army's analytic requirements.

This program element supports the Center for Army Analysis (CAA) mission to conduct decision support analysis across the spectrum of conflict in joint and multinational contexts for the purpose of supporting senior level decisions on current and future national security issues. In partial furtherance of this mission, CAA leverages a theater campaign model representing joint and combined operational maneuver that requires updating to suitably reflect emerging operational concepts such as Multi-Domain Operations.

This program element enables realization of a modernized theater campaign analysis model that provides a tractable, flexible, and extensible representation of Army capabilities and their effects on major combat operations in crisis and conflict.

The FY 2026 request was reduced by $0.668 million for Advisory and Assistance Services to promote efficiencies and advance the policies of the Administration in alignment with Executive Order 14222, "Implementing the President's Department of Government Efficiency Cost Efficiency Initiative."

The FY 2026 request was reduced by $0.015 million for civilian personnel to optimize the workforce in compliance with Executive Order 14210, "Implementing the President's Department of Government Efficiency Workforce Optimization Initiative."

A. Mission Description and Budget Item Justification

The Army Science Board (ASB) is a federal advisory committee, organized under the Federal Advisory Committee Act (FACA) and the Government in the Sunshine

Act, which provides the Secretary of the Army and Secretary of War with independent and transparent advice and recommendations on matters relating to scientific,

technical, manufacturing, acquisition, logistics, and business management functions. The ASB dates to November 1951 when the Secretary of the Army, Honorable

Frank Pace Jr., appointed twelve outstanding scientists and industrialists to a scientific advisory panel to assist him and the Army's leadership in creating an effective,

economical, and progressive fighting force using existing technology and industrial resources. Three years later, this panel was expanded and officially designated the

Army Scientific Advisory Panel (ASAP), with its first formal meeting held on November 16, 1954. In 1977, with the passage of FACA, the ASB was created to replace the

ASAP.

The ASB provided the Army with a resource of world-class scientists, engineers, technologists and operational experts as well as business, policy and managerial specialists from the private sector, academia, non-Department of War (DoW) government agencies and former senior military officers. Its members volunteered their expertise and time to address those critical national security challenges for which the Army's leadership seeks independent and unbiased technical advice. The ASB focused on issues of importance to large segments of the Army, and its products were delivered in a candid, independent and timely manner.

The Board is composed of 20 voting and a number of non-voting members, each serving three-year terms, and consultants who serve one-year terms. Membership is carefully monitored to ensure that diverse disciplines and points of view are represented. The Secretary of the Army appointed the Chair and Vice Chair from the ASB membership. ASB membership includes consultants who were appointed to provide specialized expertise for ASB studies.

Title: Army Science Board Description: The ASB Charter sets the estimated number of Board meetings at four per year. Board members serve without compensation, with the exception of reimbursement for official Board-related travel and per diem. Funds are therefore required to facilitate Board activities and related subcommittee activities. The ASB Charter states that annual requirements will typically entail a personnel cost of seven Full-Time Equivalents. Currently, the Secretary of the Army has approved four permanent subcommittees to the Board: 1) The Army Science Board Basic Science and Disruptive Technologies Subcommittee is composed of not more than 15 members and addresses issues relating to the Army's basic research and disruptive technologies, including Soldier performance	2.262	3.279	1.734

A. Mission Description and Budget Item Justification

The United States (U.S.) Army Research Institute for the Behavioral and Social Sciences (ARI) is the only Science and Technology (S&T) laboratory that conducts

research to enhance the Soldier lifecycle (e.g., selection, assignment, training, leader development) and human relations (e.g., culture of dignity, respect, and inclusion).

This project supports the non-Army Management Headquarters Activity (non-AMHA) management and administrative functions to enable ARI to accomplish its

research mission and includes activities such as budget execution, procurement oversight, Research, Development, Test, and Evaluation (RDTE) program planning

and evaluation, management control, security/safety, logistics, information technology, and personnel/manpower execution and oversight. ARI's behavioral and social

science research provides effective non-materiel solutions to help the Army adjust to changes in force size and structure, a variety of mission demands and contexts,

challenges in human relations, and budgetary constraints.

A. Mission Description and Budget Item Justification

This project supports Army Forward Elements (AFEs) in North America, Asia, and Europe for personnel, travel and overhead costs, leases on buildings, and mandatory

permanent change of station.

The AFEs mission is to support United States (U.S.) Army Rationalization, Standardization and Interoperability (RSI) efforts with Unified Action Partners (UAPs) as specified in Army Regulation (AR) 34-1 "Interoperability". AFEs promote interoperability, emphasizing operational integration across doctrines, procedures, and material solutions, and represent the U.S. Army with the land component, or "Armies", of foreign ministries of defense in their geographic areas of responsibility (AOR). AFEs facilitate interoperability through enabling U.S. Army Armaments Cooperation interaction, IAW AR 70-41 "Armaments Cooperation", with foreign ministries of defense research and development labs and non-governmental entities, such as foreign private industry and foreign academia in their geographic AOR to improve the Army's ability to operate effectively and efficiently as a component of the Joint Force, and as a member and leader of multinational alliances and coalitions across the range of military operations.

Work in this project is performed by the United States Army Transformation & Training Command (T2COM) - Futures and Concepts Command (FCC) - U.S. Army Combat Capabilities Development Command (DEVCOM).

B. Accomplishments/Planned Programs ($ in Millions)	FY 2025	FY 2026	FY 2027
Title: AFC Forward Element (AFE) Management Description: Achieving effective and lasting interoperability extends beyond technical solutions. Cultivating mutual understanding and respect with Unified Action Partners (UAPs), along with harmonizing doctrines and policies, will ensure unity of effort, maximize the effectiveness of combined operations across all domains, and serve to enhance readiness in support of national defense and strategic goals. The overseas presence and interactions of the AFEs will enable true interoperability with UAPs through this integration of operations while creating the conditions for successful Armaments Cooperation activities, such as the establishment of international agreements for military technology co-development/co-production, which are of mutual benefit to the U.S. and her allies/partners. This activity funds the U.S. Army Rationalization, Standardization and Interoperability (RSI) mission conducted by the AFEs around the globe. These funds support the infrastructure, personnel and travel requirements to support the mission. FY 2026 Plans: The AFEs will continue to promote interoperability by (1) representing the U.S. Army's interests in operational engagements with the land component, or "Armies", of foreign ministries of defense, which will identify cooperative opportunities to enhance	4.967	1.662	1.502

per Secretary of Defense guidance and especially in support of the United States (U.S.) Army. This Project partially funds the travel costs and administrative support

(studies, analysis, interpretation, equipment, etc.) required to participate in international forums, such as the North Atlantic Treaty Organization (NATO) Army Armaments

Group (NAAG), Defense Against Terrorism (DAT) and to pursue new cooperative R&D initiatives and international cooperative agreements such as memoranda

of understanding. This Project also partially funds the Five Power Senior National Representatives, Army (SNR (A)), the Technical Cooperative Program, Bilateral

SNR(A)s, and Army armaments working groups with many nations. This Project includes the United States' share of costs of the NATO Civil Budget, Chapter IX, which

funds the NATO Industrial Advisory Group (NIAG) and the Special Fund for Cooperative Planning, for which U.S. Army serves as Executive Agent. This fund also

provides for the necessary Executive Agent administrative and management costs, including support contracts, analysis, and travel. These activities support the active

oversight of the NIAG and engagement in Cooperative Planning efforts to enhance Alliance interoperability.
