This activity requests $167.8M in FY2027, 3.7% of project 655238, down 0.3% on FY2026. The R-2A exhibit describes it across FY2026–FY2027, including what the FY2027 money is planned to buy.

What the FY2027 request buys

Verbatim from the R-2A exhibit for project 655238 of PE 0605238F. 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.

FY2027 planned work

Continue to develop and modernize infrastructure to support the weapon system's lifecycle. This includes the construction of utility corridors, overseeing real estate acquisition, and pursuing paths for launch silo design and construction to inform acquisition strategies. Continue to establish standard designs for launch silos and launch centers, supporting both operational and test deployments. Continue to plan and program for facilities at key Air Force bases. Execute critical government activities, including environmental impact assessments and agreements. Continue to integrate with the NC3 Directorate to develop and mature future command and control capabilities. Continue to assess fielding requirements and timelines for the transition from MM III to Sentinel, while pursuing initiatives to optimize scheduling, mitigate transition risks, and minimize lifecycle costs. Oversee road and bridge assessments and real estate acquisitions to support new missile field designs, and accelerate environmental assessments and agreements.

FY2026 to FY2027 change

Funding increased due to the risk reduction / parallel path efforts identified through the program restructure activities to include prototyping, TMRR efforts to achieve MS-B, and the EMD prime contract schedule incentive fee identified in the "Omni-Mod” contract framework.

Before the request year

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.

FY2026 plans — current year

Establish standard designs for launch silos and launch centers, supporting both operational and test deployments. Plan and program for facilities at key Air Force bases.

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.

This activity is 3.7% of project 655238's FY2027 request and 3.7% of PE 0605238F'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.
