s, combined with a retractable and rotatable bow propulsion unit, give the ship high maneuverability. The ship's capabilities are enhanced by advanced air search and surface search radars including the AN/SPS-73 digital surface radar system that incorporates a state of the art computerized collision avoidance system. She uses the Shipboard Command and Control System (SCCS) which uses a network of computers including large screen displays and a dedicated satellite network for communications. A closed circuit TV system enables the Commanding Officer to monitor flight deck operations, machinery conditions, towing, damage control, and related activities from the bridge.
