## Summary

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

**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 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.

## Funding

| Fiscal Year | Estimate Type | Amount ($M) |
|---|---|---|
| FY2026 | Enacted | 14.2 |
| FY2027 | Request | 18.2 |

> Prior, current and budget year only — an R-2A activity carries no five-year plan. It sums exactly into its project in the request year and not necessarily in any other.
