This spaceplane is capable of delivering two kerbals and some food to low orbit space stations and returning back to the KSC runway almost without refueling in orbit.
The key feature of this spaceplane is the ability to change the orientation of wings. Oriented horisontally, they provide better performance at subsonic speeds. Orienting the wings vertically allows the spaceplane to reach higher angles of attack at hypersonic speeds increasing its maneuverability. Even more, orienting the wings not horisontally makes the plane stabilise itself at some positive angle of attack without wasting any monopropellant.
The whole concept is borrowed from soviet Spiral aerospace system lead by Lozino-Lozinsky.
