Overview (U):

(U) Titan II is a medium-lift space launch vehicle used to carry payloads for USAF, NASA and NOAA. These payloads include the USAF Defense Meterological Satellite Program (DMSP) and the National Oceanographic and Atmospheric Agency's (NOAA) Polar Orbit Environmental Satellite (POES) weather spacecraft launches into low earth orbit (LEO). Previous missions have included some classified missions and the Clementine mission to map the moon and attempted intercept of the asteroid Geographis. Plans for a Clementine II mission are in the works. Titan II has a six for six (100%) success record.


Description (U):

(U) The Titan family was established in October 1955, when the U.S. Air Force awarded the then Martin Company a contract to build an ICBM. It became known as the Titan I, the nation's first two-stage ICBM and first underground silo-based ICBM. Over 140 Titan II ICBMs, once the vanguard of America's strategic deterrent force, were built. Titan IIs also were flown in NASA's Gemini manned space program in the mid-1960s.

(U) The Titan II vehicles are decommissioned intercontinental ballistic missiles (ICBM) that have been refurbished and equipped with hardware required for use as space launch vehicles. The Martin Marietta Astronautics Group was awarded a contract in January 1986 to refurbish, integrate, and launch fourteen Titan II ICBMs for government space launch requirements.

(U) Tasks involved in converting the Titan II ICBMs into space launch vehicles include modifying the forward structure of the second stage to accommodate payload; manufacturing a new 10-foot diameter payload fairing with variable lengths plus payload adapters; refurbishing the Titan's liquid rocket engines; upgrading the inertial guidance system; developing command, destruct and telemetry systems; modifying Vandenberg AFB, CA., Space Launch Complex-4 West to conduct the launches; and performing payload integration. Deactivation of the Titan II ICBM system began in July of 1982 and was completed in June of 1987. The deactivated missiles are now in storage over at Davis-Monthan AFB, AZ.

(U) The Titan II space launch vehicle is a two-stage liquid fueled booster, designed to provide a small-to-medium weight class capability. It is able to lift approximately 4,200 pounds into a polar low-Earth circular orbit. The first stage consists of a ground ignited LR87 liquid propellant rocket, while the second stage consists of a LR91 liquid propellant rocket.

(U) The Air Force successfully launched the first Titan II space launch vehicle from Vandenberg on Sept. 5, 1988.
