From Canadian Power Wiki

Jump to: navigation, search

The County-class was a class of guided missile destroyer, the first such vessels built by the Royal Navy. Designed specifically around the Sea Slug anti-aircraft missile system, the primary role of these ships was area air-defence around the aircraft carrier task force in the nuclear-war environment. They were replaced by the Type 42 and Type 43 destroyers in the air defence role.
