The Gyro consists of four major components; the rotor and gimbal assemblies, the spring motor, the piston motor, and the yaw pickoff potentiometer. In operation, an uncage signal is applied to the piston motor which causes the piston motor to fire and release the spring motor. The spring motor overcomes the inertia of the rotor and brings the rotor up to operating speed. Series wound field coils receive an alternating voltage and sustain rotor operation. The yaw pickoff signal is provided by the yaw potentiometer. The potentiometer wiper is free to rotate 360 degrees.

The Gyro is intended for use in a torpedo control system. The Gyro will provide yaw pickoff signal to the control system.
