The County-class design attempted to give maximum protection from nuclear fallout, with the operation rooms, where the ship was fought, located 5 decks below, deep in the ship, with a lift from the bridge, which maintained some duplicated command systems. The operations room, sited the main radar, sonar, electronic warfare screens and communication data and computer links. The electronics required for the Seaslug were the large Type 901 fire-control radar and the Type 965 air-search radar. These required a great deal of weight to be carried high up on the ship, further affecting ship layout. Although superior the Type 984 3D radar was rejected as it was even heavier and excluded a twin turret 4.5-inch armament forward which was needed for gunfire support or action against surface vessels. It was hoped RN carriers with Type 984 would provide primary air target for the destroyers through a datalink. According to a RN Naval architect, "Sea Slug did not live up to expectations" and was obsolete by 1957. The compromises required by the heavy and dated Seaslug system detracted from the success and popularity of an otherwise advanced ship design. Its ineffectiveness and vulnerable magazine and missile fuel, reduced confidence in the class, which had potential as command ships, having good seaworthiness, speed and in the group two County class a spacious operations room with ADAWS.
