This computer was part of the inertial guidance system for the Titan II Intercontinental Ballistic Missile. After the end of the Cold War, Titan missiles were removed from the United States' weapons arsenal and reconfigured for use in launching commercial and other military payloads. As part of that process, the guidance systems were reconfigured and refurbished, under a contract with Litton Industries, Inc. The original guidance systems were built by the Delco Division of General Motors.
This unit is from one of the refurbished systems and was donated to the museum by Litton.
