Recovery crew members process the X-37B Orbital Test Vehicle at Vandenberg Air Force Base after completing 674 days in space. The X-37B was launched from Cape Canaveral Air Force Station, Fla., on Dec. 11, 2012. A total of three X-37B missions have been completed, totaling 1,367 days on orbit.

The X-37B program is demonstrating a reliable, reusable unmanned space test platform for the Air Force. Its objectives include space experimentation, risk reduction and concept-of-operations development for reusable space vehicle technologies that could become key enablers for future space missions.

Boeing's commitment to this space-based unmanned vehicle spans a decade and includes support to the Air Force Research Lab's X-40 program, NASA's X-37 program and the Defense Advanced Research Projects Agency's X-37 Approach & Landing Test Vehicle program.
