The Commercial Titan III, also known as CT-3 or CT-III, was an American expendable launch system, developed by Martin Marietta during the late 1980s and flown four times during the early 1990s. It was derived from the Titan 34D, and was originally proposed as a medium-lift expendable launch system for the US Air Force, who selected the Delta II instead. Development was continued as a commercial launch system, and the first rocket flew in 1990. Due to higher costs than contemporary rockets such as the Ariane 4, orders were not forthcoming, and the CT-3 was retired in 1992. rdf:langString

rdf:langString The Commercial Titan III, also known as CT-3 or CT-III, was an American expendable launch system, developed by Martin Marietta during the late 1980s and flown four times during the early 1990s. It was derived from the Titan 34D, and was originally proposed as a medium-lift expendable launch system for the US Air Force, who selected the Delta II instead. Development was continued as a commercial launch system, and the first rocket flew in 1990. Due to higher costs than contemporary rockets such as the Ariane 4, orders were not forthcoming, and the CT-3 was retired in 1992. The Commercial Titan III differed from the Titan 34D in that it had a stretched second stage, and a larger payload fairing to accommodate dual satellite payloads. All four launches occurred from LC-40 at Cape Canaveral Air Force Station. The first carried two communications satellites, Skynet 4A and JCSAT-2, and was launched at 00:07 UTC on 1 January 1990, which was 19:07 local time on 31 December 1989, making it the only orbital launch to have occurred in different years between the launch site and UTC. The launch received the International Designator 1990-001, using the UTC date. The second launch occurred on 14 March, and carried the Intelsat 603 satellite. The rocket's second stage failed to separate, and the payload could only be released from the rocket by means of jettisoning its kick motor. It was later visited by Space Shuttle Endeavour, on mission STS-49. Astronauts attached a new kick motor, which raised the satellite into a geosynchronous transfer orbit, as had originally been planned. The third launch, on 23 June, carried Intelsat 604, and was successful. There was no Commercial Titan III launch in 1991, due to maintenance work at Launch Complex 40. The final flight of the Commercial Titan III occurred on 25 September 1992, and placed NASA's Mars Observer spacecraft into heliocentric orbit, by means of a Transfer Orbit Stage.

Itu berasal dari Titan 34d, dan pada awalnya diusulkan sebagai sistem peluncuran expendable (sekali pakai) menengah-angkat untuk Angkatan Udara AS, yang memilih Delta II sebagai gantinya. Pengembangan dilanjutkan sebagai sistem peluncuran komersial, dan roket pertama terbang pada tahun 1990. Karena biaya yang lebih tinggi daripada roket kontemporer seperti Ariane 4, pesanan itu tidak akan datang, dan CT-3 sudah pensiun pada tahun 1992.

Ракета-носитель была разработана в 1990 году компанией Martin Marietta (ныне — Lockheed Martin) на базе ракеты-носителя Titan 34D. В сравнении с Titan 34D, РН Титан CT-3 обладала удлинённой второй ступенью и увеличенной головной частью для реализации возможности запуска одновременно двух космических аппаратов. Всего было произведено четыре запуска, из них один был неудачный. В связи с высокой стоимостью запуска (выше, чем конкурирующая Ариан-4) в 1992 году эксплуатация ракеты-носителя была прекращена.
