American military anti-satellite system. Study 1968. Program 922 was a non-nuclear sub-orbital ASAT in development in the late 1960's.
It would have been launched by a Thor IRBM from Johnson Atoll, using the facilities developed for the Program 437 nuclear ASAT. Program 922 would have used infrared homing and a high explosive warhead. Four 'Alternate Payload' tests of the Program 437 ASAT in 1965-1966 may have been related to development of this system.
In 1972 a hurricane hit Johnson Atoll and damaged the guidance computers beyond economic repair. In May of the same year the SALT-1 Treat was signed, which prohibited 'interference with national means of verification'. These two events resulted in the end of Program 922. Further ASAT development by the US Air Force concentrated on more flexible air-launched solid-fuel systems.

Associated Launch Vehicles
Delta American orbital launch vehicle. The Delta launch vehicle was America's longest-lived, most reliable, and lowest-cost space launch vehicle. Delta began as Thor, a crash December 1955 program to produce an intermediate range ballistic missile using existing components, which flew thirteen months after go-ahead. Fifteen months after that, a space launch version flew, using an existing upper stage. The addition of solid rocket boosters allowed the Thor core and Able/Delta upper stages to be stretched. Costs were kept down by using first and second-stage rocket engines surplus to the Apollo program in the 1970's. Continuous introduction of new 'existing' technology over the years resulted in an incredible evolution - the payload into a geosynchronous transfer orbit increasing from 68 kg in 1962 to 3810 kg by 2002. Delta survived innumerable attempts to kill the program and replace it with 'more rationale' alternatives. By 2008 nearly 1,000 boosters had flown over a fifty-year career, and cancellation was again announced. More...
