SpaceShipOne ranks among the world's first spaceplanes in the first 50 years of human spaceflight, with the North American X-15, Space Shuttle, Buran, and Boeing X-37. SpaceShipOne is the second spaceplane to have launched from a mother ship, preceded only by the North American X-15.
The White Knight and SpaceShipOne were designed by Burt Rutan and manufactured by Scaled Composites, a private company founded by Rutan in 1982. On three separate flights in 2004, White Knight conducted SpaceShipOne into flight, and SpaceShipOne then performed a sub-orbital spaceflight, becoming the first private craft to reach space.
SpaceShipOne flight 16P on September 29, 2004 and SpaceShipOne flight 17P on October 4, 2004 were successful competitive flights, winning the X Prize. The Tier One program run by Scaled Composites concluded after the retirement of SpaceShipOne, transitioning to a successor program for customer Virgin Galactic .
The Scaled Composites Model 348 White Knight Two (WK2) is a quadjet cargo aircraft that was used to lift the SpaceShipTwo (SS2) spacecraft to release altitude. It was developed by Scaled Composites from 2007 to 2010 as the first stage of Tier 1b, a two-stage to suborbital-space crewed launch system.
The generators power 15 kW electric motors; two such motors drive the rear wheels for land use, and four such motors drive four propellers (two on the horizontal stabilizer and two on the wings). [3] Although not installed to date as of July 2011, the testbed configuration will eventually incorporate rechargeable lithium batteries for ...

RocketMotorTwo (RM2) [1] is a family of hybrid rocket engines developed for the Scaled Composites SpaceShipTwo suborbital spaceplane.. The first-generation engine was developed by Sierra Nevada Corporation (SNC), [2] from the late 2000s to May 2014.
The design has two 450 cc four-cycle engines, one in each pod, which power a pair of generators that in turn power the electric motors used for propulsion. "Lithium-ion batteries in the nose of each pod will provide power during take off and an emergency backup for landing. With a cruising speed of 100 miles per hour (160 km/h), Scaled says the ...
