The Titan 23G was another expendable launch system that was used for the United States Air Force, NASA, and the NOAA. The expendable launch system was manufactured by Martin Marietta Corporation and launched from Space Launch Complex 4 at the Vandenberg Air Force Base. The first launch of the Titan 23G occurred in September of 1988. The rocket launched 13 times, and of those 13 launches only 12 were successful. Moreover, The Titan 23G stands 31.4 meters tall (103 feet), while the diameter is 3.05 meters (10 feet). The Titan 23G can have a payload weight of up to 3,600kg (7,900lbs) to low earth orbit. Notably, the Titan 23G can also hold a payload of 2,177kg (4,799lbs) to Polar LEO and 227kg (500lbs) to heliocentric orbit.The expendable launch system comes equipped with two stages and two optional third stages. The first stage that the Titan 23G uses, is a LR-87 engine; that uses one engine and two combustion chambers. The LR-87 produces 1,900kN of thrust (430,000 pounds of thrust). The second stage of the rocket is an LR-91 liquid propellant engine, that produces 445kN of thrust (100,000 pounds of thrust). The LR-91 uses a single turbopump and thrust chamber. Worth noting, the fuel type used for the first two stages of the Titan 23G is Aerozine 50 with Dinitrogen Tetroxide. Additionally, the third stage of the rocket, which is optional, can either use a Star-37XFP-ISS or an Star-37S. The last launch of the Titan 23G was on October 18, 2003.
