The Lockheed Martin X-33 was a reusable launch vehicle demonstrator developed in the United States. It was designed as part of NASA's Space Launch Initiative to test technologies for a next-generation spaceplane. The program aimed to reduce the cost and complexity of space access through single-stage-to-orbit capabilities.

The X-33 project was a collaboration between Lockheed Martin and NASA, focusing on advancing aerospace technologies. It incorporated innovative features such as lightweight composite materials and linear aerospike engines. Development began in the 1990s but was ultimately canceled in 2001 due to technical and budgetary challenges.
