Virgin Galactic has unveiled a SpaceShipTwo (SS2) design, created by Scaled Composites, that harks back to the NASA/USAF Boeing X-20 Dyna-Soar glider of the 1960s, while Scaled's carrier aircraft, White Knight II (WK2) has been given a twin-fuselage configuration.
To be launched on a Lockheed Martin Titan III rocket, Dyna-Soar was for hypersonic flight research but the programme was cancelled before the first vehicle was completed. Some of its subsystems were used in later X-15 flight research and Dyna-Soar became a testbed for advanced technologies that contributed to projects, including the Space Shuttle.

The SS2 is 18.3m (60ft) long, has a wingspan of 12.8m, a tail height of 4.5m with a passenger cabin that is 3.66m long and 2.28m in diameter. Despite being so much larger than SS1, SS2 will still use a front nose skid, and not nose gear. Released at 50,000ft (15,200m) by WK2, the rocket glider's apogee is expected to be up to 110km (68 miles).
