The RS1 is ABL Space Systems's main launch vehicle platform. Both stages are powered by ABL's E2 rocket engine, with nine to eleven[1] in the first stage, and one in the second stage. They are powered by RP-1 or Jet-A kerosene as propellant and liquid oxygen (LOX) as the oxidizer. [2]
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).
