What the FY2027 request buys
Verbatim from the R-2A exhibit for project EX6 of PE 0605031A. This is the budget justification's own description of work that has not happened yet — the one thing no other level of the budget carries.
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.
Increase is due to development and modernization of next generation SINCGARS waveform. Additionally, the on-going development of the next generation of eOTAM waveform.
FY2025–FY2026: what came before
Prior-year accomplishments and current-year plans from the same exhibit. Context for the FY2027 plan, not a series — an activity partitions its project exactly in the request year, but can under-cover it in earlier years.

Three years, and no five-year plan
An R-2A activity publishes the prior year, the current year and the budget year. The FYDP outyears exist at project and program-element level and are deliberately absent here rather than inferred. Estimate types are colored and never summed into one figure.
| Fiscal Year | Estimate Type | Amount ($M) |
|---|---|---|
| FY2025 | Actual | 14.9 |
| FY2026 | Enacted | 14.7 |
| FY2027 | Request | 17.1 |
This activity is 58% of project EX6's FY2027 request and 34% of PE 0605031A's. In the request year the activities under a project sum to it exactly; in the current year they under-cover it in about 9% of cases, so an activity's delta can legitimately exceed its parent's and the two must not be compared row to row.
