RS1, also called RSX, is Long Wall's (Formerly ABL) main launch vehicle platform. Both stages are powered by the company's E2 rocket engine, with nine (Block 1) to eleven (Block 2) in the first stage, and one in the second stage. They are powered by Jet-A kerosene as fuel and liquid oxygen (LOX) as the oxidizer, with the option to use RP-1 fuel for higher performance.
The containerized launch system and rocket can be deployed to and launched from a suitably flat site, the main requirements being access for trucks capable of carrying up to 16 m (52 ft)-long ISO containers (for the RS-1 first stage), and a flat concrete pad 46 m (151 ft) x 15 m (49 ft).
