The project is a mobile launch system with three primary components; a carrier aircraft being built by Scaled Composites (called the Stratolaunch), a multi-stage payload "launch vehicle" which would be launched at high altitude into space from under the carrier aircraft, plus a mating and integration system by Dynetics.
Stratolaunch's carrier aircraft would have a wingspan of 117 m (385 ft) , This would make it the largest airplane.
