## What the FY2027 request buys

**FY2027 planned work.** -Will begin requirements refinement -Will begin Increment 1 Development -Will begin Increment 1 Test and Evaluation -Will complete Increment 2 antenna coupler prototyping -Will begin Increment 2 antenna coupler test and evaluation -Will complete Increment 2 critical design review of antenna coupler -Will begin software integration of with ARC-260 with antenna coupler

**FY2026 to FY2027 change.** The $13.506 million increase from FY 2026 to FY 2027 is due to the development of Increment 1, a comprehensive software and firmware effort projected to last a year and a half, which is required for the successful integration of the new digital coupler in Increment 2.

## Before the request year

**FY2026 plans — current year.** -Will perform Vendor site visits to determine Vendor eligibility -Will select Vendor for digital coupler development -Will begin risk assessment and cost analysis activities -Will perform system engineering trade studies -Will begin requirements refinement and validation activities -Will begin AN/ARC-260 digital coupler prototyping
