What the FY2027 request buys
Verbatim from the R-2A exhibit for project 674920 of PE 0101328F. 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 to execute EMD contract to continue advancing Mk21A major activities to include systems engineering activities, information technology, data management, analytical capabilities and delivery of mature, low risk reentry vehicle design. • Continue to develop the critical design review for RV hardware. • Increase efforts to develop and build test assets supporting the qualification of the Mk21A and W87-1 on the LGM-35A Sentinel weapon system in collaboration with the DOE/NNSA. • Continue LGM-35A Sentinel integration activities to support delivery of the Mk21A and W87-1. • Continue ground testing at DOE/NNSA to collect relevant environmental data to feed W87-1 development. • Increase efforts in flight test planning with the LGM-35A Sentinel weapon system. • Increase efforts to conduct flight test of heatshield test vehicle and W87-1 environmental flight test unit on a RSLP Minotaur or similar launch vehicle. • Continue activities to mitigate RV development risks including prototype RV/heatshield flight test. • Continue maturing MBSE enabling the government to own the technical baseline. • Continue to develop, mature, and execute a unified certification strategy which meets nuclear surety, cyber security, and nuclear safety requirements.
Funding increased due to ramp up of LGM-35A Sentinel integration and test activities.
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.

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 | 362.9 |
| FY2026 | Enacted | 206.9 |
| FY2027 | Request | 539.8 |
This activity is 100% of project 674920's FY2027 request and 74% of PE 0101328F'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.
