## Summary

This activity requests $23.5M in FY2027, 34% of project E25, up 46% 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.** Continue supporting AMD capabilities focused on the affordability and producibility of DE systems, cannon tube production optimization, improving cold-plate brazing for high-power radar systems, and additive manufacturing processes for high-power radar systems, munitions, and scramjet components. Initiate efforts to reduce cost and improve producibility, yield, and performance of gallium nitride (GaN) transceiver circuit cards, as well as fully automate proximity module production to increase throughput.

**FY2026 to FY2027 change.** The increase in funding reflects the acceleration of DE system integration, cannon tube production optimization, full automation of proximity module production, improving cold-plate brazing for high-power radar systems, additive manufacturing production efforts for munitions and scramjet components, and improving the producibility of GaN transceiver circuit cards.

## Before the request year

**FY2026 plans — current year.** Continue developing and advancing manufacturing processes for weapon systems to include long-range precision fires, resulting in the affordability and producibility of advanced energetics, warheads, propulsion, guidance and navigation technology. Continue supporting air and missile defense (AMD) capabilities focused on the affordability and producibility of Directed Energy (DE) systems, advanced missiles and seekers, guidance and control, advanced aero structures / propulsion, air defense radar technologies, short-range air defense, long-range munitions, and indirect fire protection capability. Integrated plans are in place for multi-platform cannon tube production optimization meeting PEO GCS's cost, capacity, and fielding goals. Automate high-power interconnects and continue improving cold-plate brazing for high-power radar systems and additive manufacturing processes for high-power radar systems, munitions, and scramjet components.

**FY2025 accomplishments.** Program plans will continue to develop and advance manufacturing processes for weapon systems to include long range precision fires resulting in the affordability and producibility of advanced energetics, warheads, propulsion, guidance and navigation technology. Additionally, effort will support air and missile defense capabilities focused on the affordability and producibility of directed energy systems, advanced missiles and seekers, guidance and control, advanced aero structures / propulsion, air defense radar technologies, high energy laser weapons systems, short range air defense, long range munitions, and indirect fire protection capability. Integrated plans are in place for multi-platform cannon tube production optimization meeting program executive office ground combat system's cost, capacity, and fielding goals. Initiate efforts focusing on producibility of high power radar components to support Army acquisition performance and cost goals.
