The United States has fielded a layered missile defense system to counter and defeat current hostile missile threats. However, evolving adversarial capabilities requires new propulsion technologies that are highly responsive, agile and compatible to current MDA interceptor platforms. To meet this evolving need, Valley Tech Systems (VTS) is proposing the development of a high performance Affordable Solid Axial Stage (ASAS) for flexible high-G Delta-v impulse control and fast Thrust Vector response times. Our development approach applies the VTS extensive controllable solid propulsion Hot Gas Valve technology to a new high-performance booster hot-gas injection (HGI) Thrust Vector Control (TVC) design minimizing state of the art axial stage propulsion Size, Weight and Power (SWaP).During the phase I program VTS will conduct advanced ASAS concept design activities and conduct a subscale hot gas demonstration of a prototype HGI nozzle assembly. During the Phase II program a full scale ASAS prototype booster assembly will be developed and tested maturing the technology to TRL 4/5.Approved for Public Release | 18-MDA-9710 (6 Jul 18)
