The SA Reusable Launch Vehicle (RLV) takes off and lands horizontally, similar to a commercial aircraft, and is completely reusable. The streamlined aerodynamic configuration of the SA RLV develops over four pounds of lift for every pound of drag. Thus SA's RLV requires four times less thrust than competing vertical-ascent rocket-boosted systems. With such a drastic reduction in required thrust and the increased efficiency of the Ejector Ramjet Engine, the SA RLV will be a total of 28 times more fuel efficient compared to today's standard launch vehicles.

The streamlined shape of the vehicle is designed to reduce the amount of drag while traveling at high speeds. This allows the vehicle to more efficiently accelerate from takeoff speeds to maximum flight speed. The body of the vehicle is also designed to pre-compress the air before it enters the engine, increasing the overall engine performance. The pre-compression of the air heats the surface of the vehicle, which requires high temperature structures and material.
