HITMAN: Hypersonic InTerceptor for MANeuvering systems

If utilized as a stage for a future missile defense interceptor, scramjet propulsion enables the promise of high specific impulses and high speeds enabling longer cross range engagement envelopes. With an evolving threat landscape, the ability to provide long-range intercept capabilities for certain threats can improve the robustness of the layered missile defense system. As well, the higher specific impulse of high-speed airbreathing propulsion (2-4 times higher than that of rocket propulsion) offers the possibility of achieving greater ranges with a decreased reliance on solid rocket boosters, a key cost driver for missile defense interceptors. Recent events in the Red Sea highlight the need for alternate interceptors which do not require a $4.5M SM-6 to shoot down a $50,000 adversary UAS (Unmanned Aircraft System). Scramjet-powered interceptors are, as such, a somewhat unexplored potential solution for this system. In order to realize the potential benefits of scramjet propulsion for missile defense interceptors, three key developments are needed:Conceptual design and analysis of future interceptors to quantify potential benefits and focus development towards solving technology challenges for this applicationImprovements to the operability of the entire scramjet propulsion system across various Mach numbers, altitudes and AoAs (Angles of Attack)Development of affordable manufacturing techniques  In order to reduce costs and accelerate the development of capability, the proposed effort will leverage an existing Specter Aerospace NIGHTHAWC Hypersonic Flight Test Vehicle (FTV) as a platform for conducting this analysis. This vehicle will provide a mature baseline design, well understood performance, mature subsystems and a highly modular architecture which will be modified to serve as a test bed for the interceptor technologies. Moreover, executing this effort in compliment with two other ongoing/ near award SBIRs will provide over $8M towards the development of a combined interceptor technology test bed and future target.  The proposed HITMAN effort will also leverage existing mature scramjet engine and inlet designs from Specter Aerospace
