## Summary

This activity requests $531.9M in FY2027, 96% of project 655250, down 9.4% 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.** Continuation of EMD activities, aircraft modification, and DT&E transition planning and implementation as well as continue product support activities to include but not limited to heavy maintenance and compliance planning/implementation, initial spares, support equipment, technical order publications, and airworthiness directives.

**FY2026 to FY2027 change.** Funding decreased due to ramp down of EMD activities, product support and PSC as the program transitions to DT&E.
