This Command Module Simulator was used at Kennedy Space Center to train the Apollo astronauts. It was used in conjunction with the Lunar Module Simulator. The simulated command module was patterned after the actual spacecraft. Although motion was not simulated physically, the sensations were provided by a visual system. Realism of the mission was maintained by simulating all aspects of flight that the crew would encounter, including system sounds, failures, fire, life support, and food preparation. Three simulation engineers conducted the training missions and had the capability to insert malfunctions to enhance crew training.

Ownership was transferred to the Smithsonian in 1975.
