### Project 976 — Army Threat Sim (ATS)

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.

| Activity (R-2A) | FY2025 | FY2026 | FY2027 |
|---|---|---|---|
| Threat Information Warfare | 21.4 | 28.8 | 11.4 |
| Threat Electronic Warfare | 41.8 | 36.1 | 36.9 |
| Threat Network and Mission Command | 5.5 | 10.0 | 12.0 |

> R-2A activities carry the prior, current and budget year only — no five-year plan. Coverage is partial, so count them, never total them.

## Mission & acquisition strategy

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.
