This activity requests $13.6M in FY2027, 100% of project 3255, down 54% 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 3255 of PE 0304797N. 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

Program will be the data processing arm using AI/ML to ultimately support the missions and effects for Navy's undersea warfighting capabilities. The workload includes research, development and testing, as well as operations and maintaining lines of effort to include civilian, military, and contractor support/manpower and their related costs.

FY2026 to FY2027 change

FY 2026 to FY 2027 reflects a decrease of (-15.745M). This decrease is associated with planned project phasing (-4.969M), rephasing of FY 2027 efforts into FY 2028 and FY2029 (-9.708M), and contractor service reductions (-1.068M).

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

Program will be the data processing arm using AI/ML to ultimately support the missions and effects for Navy's undersea warfighting capabilities. The workload includes research, development and testing, as well as operations and maintaining lines of effort to include civilian, military, and contractor support/manpower and their related costs.

Money

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 100% of project 3255's FY2027 request and 100% of PE 0304797N'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.
