> **NEW START.** $33.6M requested in FY2027 with no prior-year and no current-year funding.

## Summary

This activity requests $33.6M in FY2027, 51% of project 9C89 — a new start with no prior-year and no current-year money. The R-2A exhibit describes it across FY2027, including what the FY2027 money is planned to buy.

## What the FY2027 request buys

**FY2027 planned work.** - Initiate Digital Receiver/Exciter (DREX) concept development efforts such as modeling and simulation activities to define and validate the DREX architecture and to predict performance improvements; and, conduct component-level systems engineering efforts to select and mature critical digital components design while addressing risk reduction.

**FY2026 to FY2027 change.** Increase from FY 2026 to FY 2027 reflects initiation of the DREX concept development effort. DREX will enable the upgrade of components from analog to digital, which will improve radar performance, enhance spectrum management, and enable future capability insertions.
