This activity requests $21.4M in FY2027, 40% of project 3441, down 4.9% 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 3441 of PE 0603595N. 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 expand the supplier base to address obsolescence for the COLUMBIA Submarine Class. - Finalize software sustainment plans for COLUMBIA Class CFE systems. - Implement initial tech refresh design work on selected systems.

FY2026 to FY2027 change

- Decrease due to net of updates made in accordance with the 2024 cost estimate and updated warfare center rate adjustments.

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

- Continue to expand the supplier base to address obsolescence for the COLUMBIA Submarine Class. - Finalize software sustainment plans for COLUMBIA Class CFE systems. - Implement initial tech refresh design work on selected systems.

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 40% of project 3441's FY2027 request and 6.5% of PE 0603595N'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.
