What the FY2027 request buys
Verbatim from the R-2A exhibit for project MX09 of PE 0603892C. 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.
- Develop and deliver updated threat models in support of the threat adaptation integration with in-service baselines. - Conduct studies and concepts supporting development based on real-world lessons learned. - Execute backfit capability deliveries to in-service Aegis baselines to enhance operational performance and extend system lifecycle. - Provides new capability development and threat adaptation data for in-service baselines and increased operation and sustainment of land-based test sites due to increase of Aegis Development and lab usage. - Provide real-world operational support and ship software upgrades for BMD 4.1 and BMD 5.1. - Conduct analysis of real-world operational data from the warfighter to assess future system improvements and emergent maintenance corrections required.
Increase from FY 2026 to FY 2027 provides: - Addition of a new capability development for in-service ships, including real-world lessons learned; real-world combat operational support through post-event analysis, system-level testing, maintenance builds, and post-certification threat adaptation data updates. - Ship software upgrades for BMD 4.1 and BMD 5.1 (10 BMD 4.1.2 Guided Missile Destroyers (DDGs), 11 BMD 4.1.3 DDGs, 18 BMD 5.1.3 DDGs, 8 BMD 5.1.4 DDGs, 1 BMD 5.1.5 DDG). - Increased operation and sustainment of land-based test sites due to increase of Aegis development and lab usage.
FY2026: the year under way
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.
- Conduct Modeling and Simulation (M&S) runs supporting baseline capability development. - Conduct integration, verification, and Hardware-in-the-Loop test events at test sites.
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 | 60.7 |
| FY2026 | Enacted | 10.8 |
| FY2027 | Request | 55.4 |
This activity is 32% of project MX09's FY2027 request and 6.0% of PE 0603892C'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.
