The NASA Fundamental Aeronautics Hypersonics project is focused on technologies for combined cycle, air-breathing propulsions systems to enable reusable launch systems for access to space.  Turbine Based Combined  Cycle (TBCC) propulsion systems offer specific impulse (Isp) improvements over rocket-based propulsion systems  in the subsonic takeoff and re turn mission segments and offer improved safety. The potential to realize more aircraft-like operations with expanded launch site capability and reduced system maintenance are additional  benefits.
