The function of the Operations Department is to provide the ship with navigational, tactical, and communications data and to process this data into useful information. This information is then used by the ship to make the necessary tactical decisions required during the ship's operations. Shipboard communications reception and transmission, both electrically and visually, is the responsibility of OC Division. Radiomen process the daily flow of incoming messages and send out communications originated by the ship. They also partially maintain their equipment and its associated antenna systems. Signalmen possess the training to send and receive message and tactical information by flashing light, flag hoist, and the mysterious language of semaphore.

OI Division's Operations Specialists staff the ship's Combat Information Center and use sophisticated radar techniques to plot surface and air contact positions, keeping the bridge informed of the ship's relation to it's surroundings. These men also assist in the coordination of target information for surface and underwater attack situations.

OE Division is composed of Electronic Technicians who repair, test, and calibrate and evaluate the ship's radar and communications systems along with their associated test equipment. The ET's are also responsible for departmental training in the field of operation procedure, maintenance technique and electrical and electronic safety. Electronic Warfare technicians are part of this division. They maintain and operate their namesake equipment.
