## Summary

This activity requests $194.5M in FY2027, 19% of project 640141, up 24% 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.** Phalanx Griffon: -Continue developing/integrating hardware and software solutions to continue development of an aerial node that meets C3 architectural requirements and can be tailored for hosting on tactical aircraft (e.g., F-15E/EX). -Continue to conduct planning for test and demonstration activities associated with Phalanx Griffon. -Continue development and flight testing of content routing and communications software. -Continue to develop a Technical Data Package, leveraging digital engineering, modern software development practices, and open architecture principles to enable follow-on development and integration activities on other operationally relevant platforms. -Test and Evaluation: Continue to analyze artifacts to test mission area architecture. C3 Hybrid SATCOM: -Continue developing multi-band SATCOM apertures and terminals. -Continue development of SATCOM capability to enable sharing of data in accordance with DAF BATTLE NETWORK architecture. -Test and Evaluation: Continue to analyze artifacts to test mission area architecture.

**FY2026 to FY2027 change.** Funding will increase significantly in FY 2027 as AC will continue progress of Phalanx Griffon development and hardware procurement. Additionally, development and procurement of C3 Hybrid SATCOM terminal and apertures will continue throughout FY 2027.
