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.[1][2][3][4][5][6]
Originally envisioned as a short-range robotic space tug for moving payloads in the vicinity of the Space Shuttle and Space Station,[7][8][6] the OMV was part of NASA's 1984 Space Station Freedom plan, and was initially estimated at $400 million.[1]
In 1984, NASA awarded three $1-million study contracts to Vought, Martin Marietta, and TRW.[1][9] TRW secured the $205-million OMV phase B contract in June 1986.[2] However, estimated costs had risen to $465 million by 1987, leading to the cancellation of further work on the project.[1]
