This activity requests $18.2M in FY2027, 14% of project DAT-02, up 28% 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 DAT-02 of PE 0603467E. 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

- Complete initial algorithm development and perform independent assessment. - Develop conceptual design for a fieldable Frosty prototype. - Update algorithms and demonstrate improved performance. - Deliver prototypes of Frosty software stack.

FY2026 to FY2027 change

The FY 2027 increase is due to a shift from initial development to assessments and prototyping.

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

- Perform initial field data collection in relevant environment to validate physics models and phenomenology. - Develop algorithm and software development roadmap. - Using data from tests, develop algorithms and software to produce initial target tracks.

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 14% of project DAT-02's FY2027 request and 1.2% of PE 0603467E'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.
