## Summary

This activity requests $36.9M in FY2027, 61% of project 976, up 2.3% on FY2026. The R-2A exhibit describes it across FY2025–FY2027, including what the FY2027 money is planned to buy.

## What the FY2027 request buys

**FY2027 planned work.** Continue the development of critical Electronic Attack systems focusing on highly sophisticated waveforms and specialized Digital Radio Frequency Memory and frequency following capabilities. Continue investments to incorporate these technologies across the spectrum and begin the introduction of highly advanced threat antenna technology. These technologies are critical to ensure that the pacing threats are available to meet the regulatory requirement outlined in the Threat Test Support Packages. Develop, integrate, cyber harden, test and field an additional Threat representative ground-based TDOA Electronic Support (ES) System Suite. Design, develop, integrate, cyber harden, test and field an additional Suite for Threat representative mobile/transportable system providing AoA Direction Finding (DF) ES system. Field protoype aerial ES payload that will be appended to threat representative airframes to target SUTs and training units. Integrate cognitive ES functionality into the threat systems to include leveraging Artificial Intelligence to streamline signal detection and identification. Continue development of threat representative tactical communication simulators that will leverage intelligence community models to create a realistic MDO environment. The communications emitters will be based on COTS SDR technology that performs radio radiating functions emulating threat tactical and command post communications, eliminating the need to procure dedicated communications hardware to emit commercial or military signals to complicate the MDO environments. Continue to develop highly sophisticated threat waveforms with LPI/LPD characteristics to adequately stress SUTs against threat representative capabilities. Finalize development of Ka band threat radar emitters to ensure SUTs and training units can detect, identify, and geolocate pacing threat waveforms. Additionally, fund the development of new threat waveforms focusing on National Defense Strategy priorities. Continued development of a high end threat receivers to be coupled with intelligence models for successful adjudication of Blue Forces Electronic Attack. Continue to refine the output of the threat model to yield a high-fidelity effectiveness assessment and develop multiple antenna arrays to ensure accurate threat representation. Continue development of high-fidelity threat digital twin models to support Army Operational and development testing. These models are utilized to produce validated threat waveforms and also to adjudicate the effectiveness of Blue Forces Electronic Attack (BFEA). Finally, these models will be utilized in a virtual/constructive environment to augment the quantities of live threat simulators required.

**FY2026 to FY2027 change.** FY2026 to FY2027 increase is directly attributed to keeping pace with reprogramming threat simulators with new, pacing, threat waveforms to ensure that SUTs and training units are presented with accurate representation of adversarial capabilities. Additionally, increased investments into integrating cognitive features into the ES portfolio drives the need for additional resources to keep pace with adversarial advancements.

## Before the request year

**FY2026 plans — current year.** Continue the development of critical Electronic Attack systems focusing on highly sophisticated waveforms and specialized Digital Radio Frequency Memory and frequency following capabilities. Continue investments to incorporate these technologies across the spectrum and begin the introduction of highly advanced threat antenna technology. These technologies are critical to ensure that the pacing threats are available to meet the regulatory requirement outlined in the Threat Test Support Packages. Develop, integrate, cyber harden, test and field an additional Threat representative ground-based Time Difference of Arrival (TDoA) Electronic Support (ES) System Suite. Design, develop, integrate, cyber harden, test, and field an additional Suite for Threat representative mobile/transportable system providing Angle of Arrival (AoA) Direction Finding (DF) ES system. Continue development of threat representative tactical communication simulators that will leverage intelligence community models to create a realistic MDO environment. The communications emitters will be based on commercial off-the-shelf (COTS) SDR technology that performs radio radiating functions emulating threat tactical and command post communications, eliminating the need to procure dedicated communications hardware to emit commercial or military signals to complicate the MDO environments. Continue development of high-fidelity threat digital twin models to support Army Operational and development testing. These models are utilized to produce validated threat waveforms and also to adjudicate the effectiveness of Blue Forces Electronic Attack. Finally, these models will be utilized in a virtual/constructive environment to augment the quantities of live threat simulators required.

**FY2025 accomplishments.** Develop and integrate threat digital twin models, electronic support sensors and electronic attack payloads to provide a robust and threat representative capability to support testing of Army systems such as Terrestrial Layered System and Multi-Function Electronic Warfare System. Finalize development of Threat Position, Navigation, and Timing (PNT) Jamming environment, addressing needs for Army testing across the PNT spectrum. Continue development of Electronic Attack platforms, operating on the full Radio Frequency spectrum, ranging from the HF to UHF bands. Design, develop and integrate threat radar emitter systems to address radar shortfalls (VHF; UHF; Ku and Ka Bands). Provide jamming capabilities up to 40 GHz in order to target satellite uplinks, exploitable systems for Cyber & Electromagnetic Activities (CEMA), and a threat environment required for Multi-Domain Operations (MDO). Additionally, begin the development of threat representative tactical communication simulators that will leverage intelligence community models creating a realistic Multi-Domain Operations environment. The Army Threat Systems Management Office (TSMO) will continue to support multiple Army test events including Joint Warfighting Assessment and anticipated excursion test events for numerous Systems Under Test/ Programs of Record currently identified through FY2025.
