TheTitan IIID orTitan 3D was an Americanexpendable launch system, part of theTitan rocket family. Titan IIID was flown 22 times withKH-9 andKH-11 satellites between 1971 and 1982, all successful launches.[1] Essentially aTitan IIIC with the Transtage removed, it was designed for heavyLEO payloads.

The rocket had twoUA1205 solid fuel boosters, the first stage was equipped with twoLR-87-AJ11 engines and the second stage had a singleLR-91-AJ11 engine.[1]

Part of theTitan rocket family, the Titan IIID first flew on 15 June 1971, launching the first KH-9 satellite.[2] It was retired from service in 1982, and replaced by the upratedTitan 34D. All launches occurred fromSpace Launch Complex 4E atVandenberg Air Force Base.
