X-37B collection
Designed to celebrate boundary-pushing missions and milestones
The Boeing-built X-37B is an uncrewed, autonomous spaceplane designed for advanced experimentation and technology testing. By returning hardware after each mission, it enables learning under real conditions and compresses the time from concept to dependable capability for our U.S. government partners.
The X-37B has completed seven successful missions, logging over 1.3 billion miles (2.1 billion kilometers) and spending thousands of days in space as of completion of OTV-7 in March 2025. The spaceplane launched on its eighth mission in August 2025. Each mission adds new capabilities and technology tests, making the X-37B a critical platform for advancing space technology.
