Associated Spacecraft
  • Jumpseat American military naval signals reconnaisance satellite. 7 launches, 1971.03.21 (Jumpseat 1) to 1983.07.31 (Jumpseat 7). Jumpseat signals intelligence satellites were launched by Titan 3B or 34B into highly elliptic Molniya-type orbits. More...

  • Titan The Titan launch vehicle family was developed by the United States Air Force to meet its medium lift requirements in the 1960's. The designs finally put into production were derived from the Titan II ICBM. Titan outlived the competing NASA Saturn I launch vehicle and the Space Shuttle for military launches. It was finally replaced by the USAF's EELV boosters, the Atlas V and Delta IV. Although conceived as a low-cost, quick-reaction system, Titan was not successful as a commercial launch vehicle. Air Force requirements growth over the years drove its costs up - the Ariane using similar technology provided lower-cost access to space. More...

Associated Stages
  • Agena D Nitric acid/UDMH propellant rocket stage. Loaded/empty mass 6,821/673 kg. Thrust 71.17 kN. Vacuum specific impulse 300 seconds. One of the real workhorses of US space exploration, Agena was a restartable upper stage which was also employed as a spacecraft, the whole vehicle going into orbit. A mainstay of the US Air Force reconnaisance satellite program, it also boosted early NASA probes to the moon and planets. Agena played a key role in manned space flight as the target vehicle for rendezvous and docking manoeuvres in NASA's Gemini project. It More...
