This is the Attitude Control and Ullage System module for the Titan III-E transtage. The Titan III-E was a modified Titan missile used to launch deep space probes and satellites into geosynchronous orbits. The Control and Ullage System provided roll and yaw control for the vehicle.

The Titan III-E made its first successful launch in 1974. Among the vehicle's most significant missions occurred in August and September 1975 when it launched the Viking 1 and 2 spacecraft to Mars, respectively.

This Attitude Control System was transferred from the U.S. Air Force to the Smithsonian Institution in 1970.
