This activity requests $49.0M in FY2027, 79% of project 673587, up 147% 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 673587 of PE 0305114F. 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

- Will transition from Technical Project to an ACAT III Major Capability Acquisition - Will down-select to single vendor - Will begin Major Capability Acquisition pre-production unit rapid prototyping efforts (3 prototypes) - Will conduct critical design review

FY2026 to FY2027 change

Increase due to transition from a technology project to a Program of Record in the Major Capability Acquisition pathway contract award for development of three prototype units.

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

- Conduct two system functional reviews - Continue Mobile Air Traffic System Software integration into ultimate TACOS for counter-small UAS surveillance capability - Continue TACOS development ahead of stand-alone major thrust efforts in FY 2027 - Conduct preliminary design reviews - Conduct market research - Conduct industry request for information and collect RFI Information

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 79% of project 673587's FY2027 request and 79% of PE 0305114F'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.
