Titan 2S


American intercontinental ballistic orbital launch vehicle. Version of refurbished Titan 2 ICBM with two to eight Castor 4A solid-propellant strap-on stages. Proposed in the late 1980's but never developed.

Larger GEM-40 motors were also proposed. Would have required development of a new skirt for the first stage for attachment of the solid boosters.

  • 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...
