Titan IIID
Expendable launch system used by the National Reconnaissance Office From Wikipedia, the free encyclopedia
The Titan IIID or Titan 3D was an American expendable launch system, part of the Titan rocket family. Titan IIID was flown 22 times with KH-9 and KH-11 satellites between 1971 and 1982, all successful launches.[1] Essentially a Titan IIIC with the Transtage removed, it was designed for heavy LEO payloads.
