The Boeing X-40 Space Maneuver Vehicle is a test platform for the Boeing X-37 reusable spaceplane, built by Boeing Phantom Works. It sought to test the X-37's systems in order to "reduce the cost and risk of future reusable space launch vehicle system".

The unmanned, unpowered Boeing X-40A was the first-phase flight test vehicle for the U.S. Air Force’s Space Maneuver Vehicle program that began in the late 1990s. The program aimed to develop small, reusable, highly maneuverable spacecraft for deploying satellites and conducting surveillance and logistics missions.

The Boeing X-40A, also known as the “Space Maneuver Vehicle,” was an experimental spaceplane developed by Boeing Phantom Works for NASA’s Space Maneuver Vehicle program. It served as a technology demonstrator for future crewed and uncrewed space vehicles, aiming to validate autonomous landing and recovery capabilities.

X-37試驗機 或稱為 軌道試驗飛行器 （英語： Orbital Test Vehicle，常縮寫為 OTV）是 美國 波音公司 研制的 無人 太空飛機。 X-37在起飛時需要以 火箭 搭載升空或大型飛機高空投放，再依靠自身动力进入近地轨道，並且在近地轨道上連續飛行一年以上。 在回程時，其钝型机首能使X-37较快减速，耐高温隔热瓦能抵受重返大氣層時所產生的熱力，然后像一般飛機一樣，滑翔飛行至跑道降落，同時還能在結束任務時自動返回地面，有視其為未來「太空戰鬥機」的雛形 [1]。 X-37的 …

Boeing X-40A Experimental Space Maneuver Vehicle was built to test landing technologies for the later X-37. Height: 6.71 m (22.01 ft). Span: 3.66 m (12.00 ft). The X-40A successfully completed a series of seven approach and landing tests at NASA Dryden in 2000 and 2001.
