The Titan IIIE or Titan 3E, also known as the Titan III-Centaur, was an American expendable launch system. Launched seven times between 1974 and 1977, [4] it enabled several high-profile NASA missions, including the Voyager and Viking planetary probes and the joint West Germany-U.S. Helios spacecraft.

Titan 3E, NASA’s “mighty Titan/Centaur”, was the ultimate Titan 3. It was developed after budget cuts forced the end of NASA’s Saturn programs. Titan 3E was a Titan 3D with a Centaur D-1T fourth stage and, on some missions, a TE-M-364-4 (Star 37E) fifth stage.

Mar 1, 2013 · The Air Force’s three-stage Titan 3E was selected, and General Dynamics altered the Centaur D-1A to serve as the Titan’s fourth stage. The most significant modification was the use of an entirely new shroud, which was wider than both the Centaur and Titan.

Mar 8, 2016 · All six subsequent Titan 3E launches, during 1974-77, succeeded, boosting two Helios satellites on sun-grazing 0.29 AU x 1.0 AU missions, the two Viking Mars orbiter/landers, and Voyagers 1 and 2...
