Titan IIIE

Titan III-Centaur

Mission Profile

The Titan IIIE (Titan III-Centaur) was one of the most capable American launch vehicles of the 1970s, combining a large Titan III core with strap-on solid boosters and the high-performance Centaur cryogenic upper stage for ambitious deep space and planetary missions. Standing 48.8 m tall with a 3.1 m diameter and a liftoff mass of 633 tonnes, it generated 10,680 kN of combined thrust and could deliver 15,400 kg to low Earth orbit. First flying in February 1974, the Titan IIIE launched the Viking Mars landers, Voyager 1 and 2 interplanetary probes, and Helios solar research satellites, establishing an enduring legacy as the premier deep space launch vehicle of its era.
