What the FY2027 request buys
Verbatim from the R-2A exhibit for project 643360 of PE 0604336F. 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.
- Continue aircraft and guided tail kit integration required for flight testing. - Continue F-15 flight-testing activities, Seek Eagle approval, and initiate flight test events. - Complete Davis Gun scaled testing. - Complete modeling and simulation analysis of Nuclear Explosive Package design options. - Complete component design and procurement of components to build Prototype Weapon Assemblies in preparation of future ground and flight tests. - Complete ground tests of Prototype Weapon Assemblies to include mechanical, electrical, subscale, and sled testing. - Commence sled test target construction for additional tests. - Commence risk mitigation activities to enable prototype development and/or transition to future capabilities. - Commence development of experimental impact fuze technologies to ensure proper system execution for varying scenario target impacts and identification of early integration opportunities.
FY 2027 increased compared to FY 2026 by $49.012 million for the initiation of sled test construction to prepare for multiple ground tests; increased flight test preparation activities to include initial F-15 flight test events; completion of Davis Gun scaled testing; and the development of experimental impact fuze technologies to ensure proper system execution and identification of early integration opportunities.
FY2026: the year under way
Prior-year accomplishments and current-year plans from the same exhibit. Context for the FY2027 plan, not a series — an activity partitions its project exactly in the request year, but can under-cover it in earlier years.
- Continue modeling and simulation analysis of Nuclear Explosive Package design options and validate with sled test results. - Continue component design and procurement of components to build Prototype Weapon Assemblies in preparation of future ground and flight tests. - Continue ground tests of Prototype Weapon Assemblies to include mechanical, electrical, subscale, and sled testing. - Continue aircraft integration required for flight testing. - Complete subscale component and subsystem testing. - Complete initial sled test target construction. - Commence F-15 flight testing activities. - Commence Davis Gun scaled testing.
Three years, and no five-year plan
An R-2A activity publishes the prior year, the current year and the budget year. The FYDP outyears exist at project and program-element level and are deliberately absent here rather than inferred. Estimate types are colored and never summed into one figure.
| Fiscal Year | Estimate Type | Amount ($M) |
|---|---|---|
| FY2025 | Actual | 37.7 |
| FY2026 | Enacted | 42.5 |
| FY2027 | Request | 91.6 |
This activity is 100% of project 643360's FY2027 request and 100% of PE 0604336F'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.
