Apollo Command Service Module (CSM) Pitch Actuator utilized for ‘steering’ the spacecraft on its journey to and from the moon. The electro-mechanical actuator was installed in pairs on the Service Propulsion System (SPS) AJ10-137 main engine to change nozzle orientation in Pitch and Yaw. The nozzle deflection in conjunction with rocket engine firing (upon command from computer or crew input) resulted in thrust vectoring to alter the course of the CSM (and the Lunar Module when docked with the CSM). This gimbal actuator is a mature example that was deaccessioned directly from North American Rockwell at the conclusion of qualification testing for the Block II Apollo CSM.
