## Summary

This activity requests $35.0M in FY2027, 58% of project 0219, down 17% 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 support of Advanced Processing Builds installed on SSN688I, SSN 21, SSBN, SSGN, and VA Class Submarines. -Continue integration and testing associated with signal processing in support of Large Vertical Array (LVA) on SSBN and VA Class submarines. -Transition A-RCI APB content delivery to SWFTS Continuous Capability Insertion Model through implementation of Development, Cyber Security, and Operations (DevSecOps) and Agile development for flexible APB content releases to fleet platforms. These efforts increase focus on machine learning, automation, and behavioral analysis.

**FY2026 to FY2027 change.** FY 2026 to FY 2027 reflects a decrease of $-7.292M to fund other Department priorities.
