 A more modern derivative of the aircraft cruiser is the helicopter cruiser which could typically operate at least 4 or more helicopters including medium and heavy lift varieties.This is in contrast to surface warships such as cruisers, destroyers, and frigates which have basic aviation facilities, including a hangar and landing pad, that are sufficient only for 1–2 light/medium helicopters.Post-war the United Kingdom reconstructed the "Tiger"-class cruisers, and into helicopter cruisers, retaining their guns forward but having their aft guns removed for the installation of a hangar and helicopter platform for the operation of four Sea King helicopters.
