What the FY2027 request buys
Verbatim from the R-2A exhibit for project BY8 of PE 0607148A. 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.
FY 2027 research, development, test and evaluation (RDT&E) funds in the amount of $28.462 million continues to support Modernization Development Efforts and mitigation of Emerging Threats. This funding enables continued response to evolving battlefield threats as identified in the VOLT CFRS, dated 15 February 2022. Funds also support the integration and testing of the Multi-Mission Radar (MMR) into the Distributed Digital Receiver Exciter (DDREX) software baseline, which is a component of Capability Set #3. These capabilities are essential for critical software improvements and enhanced system survivability.
FY 2027 funding increase due to additional integration work required for MMR software and the ramp up of software development to continue to evolve the system to counter advanced threats.
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.
FY 2026 research, development, test and evaluation (RDT&E) funds in the amount of $12.854 million continues to support the Modernization Development Efforts and Emerging Threats. This requirement will continue to allow the ability to address evolving battlefield threats identified in the VOLT CFRS, 15 February 2022. Funds support engineering and development activities, software updates, modeling & simulation, cyber & information assurance patches & updates, and post-test data analysis on the radar's performance. Funds also support Multi-Mission Radar (MMR) software integration into the Distributed Digital Receiver Exciter (DDREX) software baseline, enabling early detection and classification of airborne threats. These capabilities are necessary to allow continued survivability software improvements.
FY 2025 research, development, test and evaluation (RDT&E) funds in the amount of $8.094 million continues to support the Modernization Development Efforts and Emerging Threats. This requirement will continue to allow the ability to address evolving threats on the battlefield that are in the VOLT CFRS, 15 February 2022. This requirement is necessary to allow continued survivability improvements.
Three years, and no five-year plan
An R-2A activity publishes the prior year, the current year and the budget year. The FYDP outyears exist at project and program-element level and are deliberately absent here rather than inferred. Estimate types are colored and never summed into one figure.
| Fiscal Year | Estimate Type | Amount ($M) |
|---|---|---|
| FY2025 | Actual | 8.1 |
| FY2026 | Enacted | 12.9 |
| FY2027 | Request | 28.5 |
This activity is 31% of project BY8's FY2027 request and 31% of PE 0607148A'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.
