The Rocketplane XP is a suborbital spaceplane under development by Rocketplane Limited, Inc.. The XP is based on a heavily-modified Learjet 25 airframe, with changes including the addition of a delta wing and V-tail. The vehicle is powered by two jet engines and a rocket engine, enabling it to reach suborbital space. The XP is designed to operate from existing spaceports in a manner consistent with established commercial aviation practices.
