### Project 634920 — Aerospace Systems Integration & Demonstration

This project demonstrates advanced aerospace system technologies. Aerospace system technology integration efforts are accomplished through integration of various technologies to include autonomy, power and thermal, propulsion (rocket, turbine, scramjet, etc.), air vehicle and weapon systems for demonstration in near realistic operational environments and ranging from subsonic, supersonic, to hypersonic speeds. Advanced aerospace system technologies are demonstrated to enhance the capability of current and future aerospace systems. Aerospace Technology Dev/Demo, received a Congressional add for FY 2026 $2.500 million for HITECH Beam Director Development. Upon Congressional spend plan approval, an Internal Reprogramming (IR) will be processed aligning the funding to PE0603605F for proper execution.
