> **NEW START.** $10.3M requested in FY2027 with no prior-year and no current-year funding.

## Summary

This activity requests $10.3M in FY2027, 75% of project 633151 — a new start with no prior-year and no current-year money. 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.** - Complete base defense demonstrations of Directed Energy Frontline Electromagnetic Neutralization and Defeat (DEFEND) system in collaboration with the Navy. Activities include: Demonstrating of full kill chain in testing; Work with warfighters to develop CONOPS, CONEMPS, and TTPs. - Continue design effort of airborne HPM systems. This work will focus on the counter missile and counter unmanned aerial systems (c-UAS) mission. Activities include: conformal antenna design, build, and test; HPM source packaging to reduce size, and weight. - Continue HPM antenna design efforts for base defense and airborne applications. Activities include: foldable antennas to measure the technical performance parameters. The antenna will lead to greater system range while not increasing size or setup time of the system. - Continue efforts to increase HPM output power while reducing logistical and maintenance requirements. Activities will focus: on reducing the size of systems to maintain lethality while obtaining compliance with the Air Force Agile Combat Employment doctrine. The objective is to meet the lethality and capability of DEFEND in 33% of the footprint. - Commence development of a fully mobile, fire-on-the-move counter-UAS HPM capability. Activities include: HPM integration into a vehicle platform. - Commence live operational baselining of counter-UAS. Activities include: Deploying additional system; transitioning system out of the lab to a program executive office.

**FY2026 to FY2027 change.** FY 2027 increase of 10.321 million is due to the transfer of the High Power Microwave Technologies effort and associated funding from Project 633152. The overall funding for High Power Microwave technologies increased from the FY26 PB of 4.383 million by 5.938 million, supporting high-fidelity,multi-physics modeling for optimizing laser weapon system designs and commencing development of mobile fire-on-the-move counter-UAS capabilities and live operational baselining of counter-UAS systems.

## Before the request year
