A totally new design and new concept, meant to avoid political and economic costs and problems of full-size aircraft carriers. These ships were initially meant as ASW-only vessels to operate in NATO ASW groups for service in the North Atlantic, as replacements for the Tiger class cruisers which had been converted to major ASW vessels. They were designed to operate VSTOL aircraft for defensive purposes, making them very versatile shisp; they have served in many roles worldwide.

Originally classed as "through deck cruisers" for political reasons, they are now known as VSTOL or ASW carriers. Just prior to the Falklands crisis the entire program was in danger; the first ship had been offered for sale to Australia, and the 3rd would have been cancelled.

A relatively "bulky" hull, allowing space for the extensive command facilites needed in the role of ASW group flagship. Large starboard-side island, full-length axial flight deck on the port side, with "ski jump" at the bow. Full hangar. Gas turbine propulsion. Originally planned to carry Exocet on the bow, to the starboard side of the skijump, but the missiles were replaced by additional aircraft parking space.
There are minor variations in the close-in armament, angle of the skijump, etc.

Each ship has undergone a major refit, updating each to the latest standards. The skijump angle has been increased to 15 degrees in all. The Sea Dart launcher has been removed to allow additional aircraft parking space.

Can operate as ASW ships (with Harriers in a defensive role), or as light fleet/strike carriers with the Harriers in an offensive/strike or fleet defense (interceptor) role. Have seen extensive service worldwide. Normally one is deployed, one in maintenance/training, and one in major overhaul.
