5. Orbital Vehicles
The U.S. Air Force describes its X-37B Orbital Test Vehicle as an unmanned, reusable space craft to transport payloads and conduct experiments in orbit. If this sounds familiar, it’s because these were the same missions performed by the scrapped space shuttle program.
The programs appear to be living up to expectations with one orbiter remaining in orbit for 674 days on a mission the Air Force won’t disclose. Although the Air Force goes out of its way to say it is an unmanned program, some aerospace analysts belief the X-37B is actually the beginning of a manned combat vehicle. Such a vehicle could be launched from Florida atop a rocket, separate, orbit the planet and land troops anywhere on Earth in a matter of minutes. The Marine Corps takes this concept seriously and has a concept called Small Unit Space Transport and Insertion (SUSTAIN).
