Titan IVA

Titan IV Complementary EELV SLV-7

Mission Profile

Titan IVA was one of the most powerful American launch vehicles of its era, a heavy-lift workhorse built by Martin Marietta to deploy massive national security and scientific payloads. Standing 62.2 meters tall with a liftoff mass of 862,000 kg and generating 13,760 kN of thrust from its twin solid rocket motors and liquid core, it could deliver up to 17,700 kg to low Earth orbit. First flown in June 1989, the Titan IVA served the United States Air Force for over a decade, launching KH-11 reconnaissance satellites, the Cassini-Huygens spacecraft to Saturn, and other critical missions that demanded heavy-lift performance unavailable from any other vehicle in the American inventory at the time.
