## Summary

This activity requests $120.6M in FY2027, 78% of project 655271, up 522% 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.** Will continue product refinement, studies, ground, and flight testing in support of the KC-46 weapon system to include receiver certifications, simulator data collection, and completion of IOT&E events/reporting. Incrementally fund boom telescope actuator redesign (BTAR) Engineering Change Proposal (ECP) efforts and solution for Remote Vision System (RVS), to address deficiencies and improve capability.

**FY2026 to FY2027 change.** Funding increased due to ramp up in support activities such as BTAR redesign, receiver activities and correcting deficiencies.

## Before the request year

**FY2026 plans — current year.** Continue product refinement, studies, ground, and flight testing in support of the KC-46 weapon system to include receiver certifications, simulator data collection, and completion of IOT&E events/reporting.
