Description: The Delta expendable launch vehicle program started in 1959 to meet the requirements of NASA. The Delta I launch vehicle propulsion system took its first stage from the USAF's Thor Intermediate Range Ballistic Missile (IRBM) and the second stage from the US Navy's Vanguard ballistic missile. In 1960 the first Delta I vehicle was capable of delivery a 100-pound payload into the GTO (Geosynchronous Transfer Orbit).

The US Air Force started the Delta II program in 1987 to put into orbit 18 NAVSTAR GPS satellites. The success of the GPS system increased the number of Delta II launch vehicles ordered by the USAF and therefore the success of the Delta II program.

The propulsion system can be configured with two or three stages (typically one RS-27 and two LR-101 for the first stage, one AJ10 motor for the second stage and one Star-48B for the optional third stage) plus 3, 4 or 9 GEM boosters depending on mission needs. Payloads of up to 4,750 lb (2,142 kg) can be put into the GTO and loads of up to 13,280 lb (6,000 kg) into low Earth orbit.

Currently, the Delta II launch vehicle is employed to put into orbit GPS satellites, as well as commercial and civil payloads into low-Earth, polar, GTO and stationary orbits.
