The Transfer Orbit Stage (TOS) was an upper stage developed by Martin Marietta for Orbital Sciences Corporation during the late 1980s and early 1990s. The TOS was designed to be a lower-cost alternative to Inertial Upper Stage (IUS) and Centaur G upper stages. The TOS was designed to be deployed by the Titan 34D, Commercial Titan III and Space Shuttle.
