The first of two retired 747-400 transport airliners procured by the newly-founded Stratolaunch Systems arrived at the Scaled Composites hanger in Mojave, California before moving to subcontractor BAE’s hangar for disassembly. Critical systems will be salvaged from tail number N196UA (purchased from United Airlines) and used in the construction of the carrier aircraft for Stratolaunch’s proposed air-launch system.
“The arrival of the first 747 aircraft in Mojave is extremely exciting for our team. This demonstrates Mr. Allen’s commitment to press forward with establishing a space transportation system that will change the way we currently perform space launch,” said Stratolaunch CEO and President Gary Wentz, referring to Paul Allen, founder of Stratolaunch.
Along with BAE, Scaled Composites will salvage the engines, landing gear, hydraulics, and other key systems from the aircraft and reassemble them into a custom composite airframe. A second retired 747-400 aircraft, also purchased from United Airlines, is slated to arrive at the Scaled Composites hangar later this month.
In order to carry the orbital portion of the system and the modified Falcon 9 rocket required to loft it into LEO, Scaled Composites must construct the largest aircraft (in terms of wingspan) in the world. The carrier “mothership” will use six of the 747’s turbofan engines to lift the 550-ton vehicle (including the 200-ton Falcon 9 booster stage), and will require a runway of 3.5 kilometers to takeoff.
Founded by Microsoft co-founder Paul Allen in December 2011, Stratolaunch Systems aims to partner Burt Rutan, Allen’s former colleague on SpaceShipOne, with Space Exploration Technologies (SpaceX) to create a revolutionary air-launched orbital launch vehicle. The purpose of the system is to increase the payload the Falcon 9 rocket can loft into orbit by launching it from high in the stratosphere, potentially reducing cost per mass of reaching orbit.
