On December 13, 2011, Allen announced the creation of Stratolaunch Systems, based at the Mojave Air and Space Port. The Stratolaunch is a proposed orbital launch system consisting of a dual-bodied, 6-engine jet aircraft, capable of carrying a rocket to high altitude; the rocket would then separate from its carrier aircraft and fire its own engines to complete its climb into orbit. If successful, this project would be the first wholly privately funded space transport system. Stratolaunch, which is partnering with Orbital ATK and Scaled Composites, is intended to launch in inclement weather, fly without worrying about the availability of launch pads and to operate from different locations. Stratolaunch plans to ultimately host six to ten missions per year. On April 13, 2015, Vulcan Aerospace was announced. It is the company within Allen's Vulcan Inc. that plans and executes projects to shift how the world conceptualizes space travel through cost reduction and on-demand access.
