Titan IIIC

SLV-5C Titan 3C

Mission Profile

The Titan IIIC (SLV-5C, Titan 3C) was a three-to-four-stage American heavy-lift launch vehicle in the Titan family, the first Titan variant with large solid rocket strap-on boosters that transformed the ICBM-derived core into a heavy-lift space launcher. Standing 42 m tall with a 3.1 m core diameter and a liftoff mass of 626 tonnes, it generated 10,680 kN of liftoff thrust and could deliver 13,100 kg to low Earth orbit or 3,000 kg to geostationary transfer orbit. First flying in June 1965, the Titan IIIC launched the first synchronous-orbit military communications satellites and heavy classified payloads, establishing the Titan III as the backbone of US military space launch for two decades.
