Air Force was planning a similar craft, the Space Maneuver Vehicle, and Boeing built a single X-40A test aircraft for the Air Force. NASA began development of a small, unmanned spaceplane concept in the mid-1990s while simultaneously, the U.S. Without a human crew, an unmanned spaceplane could spend weeks, months, or even years in low earth orbit-as long as the mission requires-before returning to Earth. An unmanned spaceplane can be far smaller than a manned one, requiring less thrust and a smaller rocket to put it into space. One option to boost spaceplane readiness and lower costs was to dispense with human crews entirely, which meant getting rid of their crew living spaces and life support systems.
Worse, the Shuttle took months to refurbish between flights, making it nowhere near as responsive a platform as originally planned. Unfortunately, the Space Shuttle ended up being a far more maintenance-intensive shuttle than original envisioned and failed to lower payload-to-orbit costs. The Shuttle, designed to be flown frequently and with recoverable, reusable booster engines, was supposed to dramatically lower the cost of transporting people and hardware to low-Earth orbit. The story of the X-37B starts in the 1990s, when NASA was studying cheaper alternatives to the Space Shuttle orbiter.
