Apollo Command Service Module (CSM) Main SPS Engine Gimbal Pitch Actuator, measuring approximately 25è x 11.5è x 6.5è, designed for ‰Û÷steering‰Ûª 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). The actuator has two "Model No. 3180G" schematic plates on the top, and a Lear Siegler identification plate: "Linear Servo Actuator, Type: Pitch, Rating: 450 lbs‰Û_Spec. AGC DWG. 085469-1E, AGC Serial AP-7, Part 56002-009, Model 3180G, Serial XL-07."
