## Summary

This activity requests $54.0M in FY2027, 59% of project BY8, up 199% on FY2026. The R-2A exhibit describes it across FY2025–FY2027, including what the FY2027 money is planned to buy.

## What the FY2027 request buys

**FY2027 planned work.** FY 2027 research, development, test and evaluation (RDT&E) funds in the amount of $54.043 million supports the continued enhancement of system survivability and the development of advanced electronic protection software techniques for DDREX Capability Sets #3 and #4. This funding enables developmental electronic protection software demonstrations on the tactical hardware associated with DDREX Capability Sets #3 and #4.

**FY2026 to FY2027 change.** FY 2027 funding increase due to the ramp of up of software development for advanced electronic protection techniques and additional integration work required for DDREX Capability Sets #3 and #4.

## Before the request year

**FY2026 plans — current year.** FY 2026 funding of $18.086 million supports the continuation of the survivability improvement effort and enhanced electronic protection software techniques for the design and development of DDREX Capability Sets #3 and #4.

**FY2025 accomplishments.** FY 2025 research, development, test and evaluation (RDT&E) funds in the amount of $16.496 million supports the start of the survivability improvement effort for the design and development of DDREX Capability Sets #3 and #4. This will require the development and integration of an additional high performance data processing board to the DDREX's processor assembly.
