The US Space Force X-37B Spaceplane Is 29 Feet Long, Weighs 11,000 Pounds and Has a Payload Bay 7 Feet Long. Nobody Outside the Program Has Ever Been Told What Goes Inside It.

The X-37B is 29 feet long with a 15-foot wingspan, weighs 11,000 pounds, and has a payload bay about 7 feet long. It launches on an Atlas V or a Falcon 9, stays in orbit for hundreds of days at a time, and lands itself on a runway. The US Space Force announces the launch and the landing. What the spaceplane does in between, and what it carries in that bay, is classified.
