It is boosted into space by a launch vehicle, re-enters Earth's atmosphere, and lands as a spaceplane. The X-37 is operated by the Department of the Air Force Rapid Capabilities Office, in collaboration with the United States Space Force, [1] for orbital spaceflight missions intended to demonstrate reusable space technologies.

2016年2月24日 · The X-37 is a reusable orbital launch vehicle put into orbit atop an Atlas V rocket. It was built by Boeing. The vehicle is used by the U.S. military.

2006年4月7日 · The X-37 is principally used for space exploration, risk reduction and developing reusable space vehicle technologies. It is derived from the X-40A spaceflight and is one of the most modern spacecraft in the world. Fuelled with military fuel JP-8 and hydrogen peroxide, the Rocketdyne engine of the X-37 is designed to run for nine months.

The X-37A airframe is essentially the X-40A scaled up to about 120%. In addition to the X-40A's features, the X-37A is fully equipped for space flight, having a rocket engine for orbital maneuvers, an advanced reusable thermal protection system, a payload bay and a navigation/flight-control system for orbital and atmospheric flight.

x-37验证机最初是nasa（美国国家航空航天局）与波音公司签订的合同，目标是验证轨道飞行试验和先进再入技术，通过新技术的运用降低航天成本，即使现在的x-37b也仅仅是轨道试验飞行器(otv)，距离实战还有很长的距离。

Reusable satellite satellite built by Boeing for NASA, USAF, USA. Launched 2010 - 2015. AKA: OTV. Status: Operational 2010. First Launch: 2010-04-22. Last Launch: 2015-05-20. Number: 4 . Gross mass: 3,200 kg (7,000 lb). Height: 8.38 m (27.49 ft). Span: 4.57 m (14.99 ft).

The Boeing X-37 is an unpiloted demonstration spaceplane that is intended to test future spaceflight technologies while in orbit and during atmospheric reentry. It is a reusable robotic spacecraft based on the smaller X-40. The X-37 began as a NASA project in 1999, then was

2025年3月7日 · CAPE CANAVERAL, Fla. (AP) — The U.S. military’s classified mini space shuttle returned to Earth on Friday after circling the world for 434 days.. The space plane blasted into orbit from NASA’s Kennedy Space Center in December 2023 on a secret mission. Launched by SpaceX, the X-37B vehicle carried no people, just military experiments. Its predawn touchdown at Vandenberg Space Force Base ...
