## Summary

This activity requests $17.1M in FY2027, 58% of project EX6, up 17% 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.** Funding will support the modernization of the Single Channel Ground and Airborne Radio System (SINCGARS) waveform to develop a more robust Electronic Warfare (EW) resiliency to include initial Frequency Hopping 4 (FH4) development and hardening of Patriot data mode to increase EW performance and range; Warrior Robust Enhanced Network (WREN) development of transport optimizations for next generation battlefield applications, integration of enhanced data modes, continued development of Denied, Disrupted, Intermittent, and Limited (DDIL) modes, Wren Release B maturation, hardening and problem fixes in support of 1QFY27 full Release B; enterprise Over The Air Management (eOTAM) 3.0 development and final release as well as eOTAM 3.0.1 development contract award. Continuous monitoring of portability compliance based upon incremental planned releases in FY27. Integration of baseline versions into leader and manpack radios, subsequent capability enhancements based on user feedback, and conforming to security compliance protocols for porting on type 1 radios. Continued Vertically Encapsulated NetOps Microservices (VENOM) development of Mobile Power Unit 5 (MPU5) radio compatibility with software application enhancements. Ongoing maintenance of cyber security posture for VENOM v4 and ensuring upkeep of Enterprise Mission Assurance Support Service (eMASS) records documenting scanned findings and Information Assurance Vulnerability Alerts / Security Technical Implementation Guides (IAVAs/STIGS). Support will include efforts to alleviate Cyber Electro-Magnetic Activities (CEMA) threats for SINCGARS and WREN, including Lead Service activities, and Radio Services. As well as Post Deployment Software Support (PDSS) of fielded versions of network waveforms and network services software products.

**FY2026 to FY2027 change.** Increase is due to development and modernization of next generation SINCGARS waveform. Additionally, the on-going development of the next generation of eOTAM waveform.

## Before the request year

**FY2026 plans — current year.** Funding will support the Single Channel Ground and Airborne Radio System (SINCGARS) Frequency Hopping 4 (FH4) waveform development; Warrior Robust Enhanced Network (WREN) developmental Release B maturation, hardening and problem fixes in support of 1QFY27 full Release B; enterprise Over The Air Management (eOTAM) 2.2.1 development and final release as well as eOTAM 3.0 development contract award. Support will include efforts to alleviate Cyber Electro-Magnetic Activities (CEMA) threats for SINCGARS and WREN, including Lead Service activities, and Radio Services. As well as Post Deployment Software Support (PDSS) of fielded versions of network waveforms and network services software products

**FY2025 accomplishments.** Funding will support the Single Channel Ground and Airborne Radio System (SINCGARS) Frequency Hopping 4 (FH4) waveform preliminary system requirements analysis and development; Warrior Robust Enhanced Network (WREN) developmental Release B maturation, hardening and problem fixes; enterprise Over The Air Management (eOTAM) 2.2 development and final release as well as eOTAM 2.2.1 development contract award. Support will include efforts to alleviate Cyber Electro-Magnetic Activities (CEMA) threats for SINCGARS and WREN, including Lead Service activities, and Radio Services.
