The dual-fuselage “launch platform” has a wingspan of 385ft (117 m) and will drop-launch rockets that will carry satellites at an altitude of 35,000ft (10,700m). The first rocket to be used on the launch system, the Pegasus, is scheduled to be in use by 2020 and will be able to carry payloads of up to 370kg (815 lb).

Meanwhile, Virgin Orbit continues to make progress on its launch system and has recently conducted a fit check of its LauncherOne rocket to its airborne launch platform, which is a customized 737. The company plans to conduct the first flight test of its launch system, which is designed to carry payloads of up to 300kg into orbit, before the end of this year.
