What project 622405 buys

This project investigates, analyzes, and develops applied technologies that enable future multi-Mach, responsive high-speed/hypersonic weapons and platforms (vehicles) via modeling, simulation and analysis (MS&A), and ground and flight tests. The extreme conditions high-speed/hypersonic weapons and platforms are subjected to manifest as complex multi-disciplinary technical challenges, namely: structure/system durability, broad operability from Mach 0 to Mach 5+ (multi-Mach operability), vehicle-level integrated power and thermal management, and integration of mission systems. The development of technical solutions to these multi-disciplinary challenges at the subsystem level, and the subsequent integration of them at the system level, is critical to reduce the risk and time required to transition technologies into operational systems. Digital material management, and validation via ground test capability are utilized to develop and deliver an integrated digital environment (IDE) to assess technology, evaluate its impacts, and make capability-focused investment decisions. Aerospace Systems Technologies, received a Congressional add for FY2026 $2.500 million for Hypersonic high-speed aerodynamics research. Upon Congressional spend plan approval, an Internal Reprogramming (IR) will be processed aligning the funding to PE0601102F for proper execution.

Inside the project

3 accomplishments / planned programs

The R-2A exhibit — the only level of the budget that describes work that has not happened yet. Activities carry the prior, current and budget year only, no five-year plan. 2 of them describe FY2027 work in enough detail to have their own page; the rest are shown here in full. Coverage is partial across the corpus, so count activities, never total them.

FY2027 planned work In FY 2027, the funding and technical activities from this effort were realigned to High-Speed Systems Technology Development and High-Speed Propulsion Technology Development effort within this Project.

FY2026 to FY2027 change FY 2027 funding decreased compared to FY 2026 by $15.352 million due to the transfer of the High-Speed Vehicle Aeromechanics Technology Development effort within this Project to enable acceleration of integrated system and propulsion capabilities and capture realistic representation of integrated aeromechanical work.

FY2026 plans — current year Continue to mature critical technologies for high speed/hypersonic flight with primary emphasis on durable, survivable systems and secondary emphasis on longer range and heavier payloads; -Activities include studies of low-speed performance, configuration trades, and data collection on high-speed platforms operating outside of cruise conditions. Continue development of multi-disciplinary design and analysis techniques and tools with emphasis on the digital engineering environment; -Activities include vehicle geometry, trajectory and performance evaluations. Continue development of high-speed system concepts that provide revolutionary capabilities through configuration research; -Activities…
