The Titan IIIM was a planned American expendable launch system, intended to launch the Manned Orbiting Laboratory and other payloads. Development was cancelled in 1969. The stretched core stage was used on some versions of the Titan IIIB and the projected UA1207 solid booster rockets were eventually used on the Titan IV.[1][2]

Development
- 1969 April 27 - First static test firing of Titan IIIM seven segment solid rocket booster motor. Firing took place at the United Technologies Coyote Canyon test site at the southern edge of San Jose, California,[3] and generated 700,000 kgf (6,900,000 N; 1,500,000 lbf) for two minutes.[1]
Planned flights
- 1970 - Uncrewed Gemini-B/Titan IIIM qualification flight
- 1971 - Uncrewed Gemini-B/Titan IIIM qualification flight
