This device, designed by TRW, Inc., is a backup to the Apollo Guidance Computer that was installed on the Lunar Module. If needed, it was to perform only critical guidance and control functions in case of a failure of the primary system. It may have been one of the first spacecraft systems to use "strapdown" gyro technology. This unit is unflown.

The Abort Guidance System was activated at least twice during the Apollo program: on the Apollo 10 and Apollo 13 missions.

Donated by TRW to the Museum in 1973.

Gift of TRW.
