Orbital Maneuvering Vehicle

The Orbital Maneuvering Vehicle (OMV) was a project developed by NASA in the 1980s, aiming to create a reusable, remotely controlled, free-flying vehicle capable of performing various on-orbit missions and services to support orbiting spacecraft.

Originally envisioned as a short-range robotic space tug for moving payloads in the vicinity of the Space Shuttle and Space Station, the OMV was part of NASA's 1984 Space Station Freedom plan, and was initially estimated at $400 million.

In 1984, NASA awarded three $1-million study contracts to Vought, Martin Marietta, and TRW. TRW secured the $205-million OMV phase B contract in June 1986. However, estimated costs had risen to $465 million by 1987, leading to the cancellation of further work on the project.
