## Summary

This activity requests $21.9M in FY2027, 4.2% of project 672671, up 2.6% 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.** Continued development and testing of AESA Phase 3.4 radar software capabilities which include completing integration of Enhanced Data Link, Improvements and Enhancements to A-A and A-G Combat Identification and Maritime Detection; Electronic protection improvements and engineering support to complete F-16 post block implementation of Ethernet messaging. Additional engineering support to improve RF compatibility with SIU to complete RFC CDD. Additional engineering and software support to improve radar integration with derived requirement RIP+.

**FY2026 to FY2027 change.** Increase of $0.564M from FY26 to FY27 is minimal, FY27 burn rate expected to be very similar to FY26.

## Before the request year

**FY2026 plans — current year.** Complete and field AESA Phase 3.3 software capabilities. Begin development of AESA Phase 3.4 radar software capabilities which include completing integration of Enhanced Data Link, Improvements and Enhancements to A-A and A-G Combat Identification and Maritime Detection; Electronic protection improvements and engineering support to complete F-16 post block implementation of Ethernet messaging. Additional engineering support to improve RF compatibility with SIU to complete RFC CDD. Additional engineering and software support to improve radar integration with derived requirement RIP+.
