Titan IIIM with Apollo CSM Study

Titan IIIM

Mission Profile

The Titan IIIM with Apollo CSM Study (Titan IIIM) was a proposed three-to-four-stage American heavy-lift launch vehicle in the Titan family, studied as an alternative to Saturn for launching Apollo Command and Service Modules under the Apollo programme. Standing approximately 42 m tall with a 3.1 m core diameter and a liftoff mass of 626 tonnes, it would have generated 10,680 kN of liftoff thrust. Conceived around 1970, the Titan IIIM Apollo study explored whether Titan could provide a lower-cost crew-rated launch option but was not pursued as the Saturn IB continued to serve the programme.
