## Summary

This activity requests $1.76B in FY2027, 100% of project 643308, down 15% 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.** Continue test aircraft build, scaling manufacturing, infrastructure and capacity across the industrial base, and execution of test and evaluation activities. This funding will keep B-21 Raider development on track in support of the program's continued transition through low-rate initial production and fielding.

**FY2026 to FY2027 change.** FY27 funding will be a decrease of $322.082M. This decrease in funding is primarily due to the continued transition from EMD to Production.

## Before the request year

**FY2026 plans — current year.** Continue test aircraft build, scaling manufacturing, infrastructure and capacity across the industrial base, and execution of test and evaluation activities.
