Landing platform helicopter

Landing platform helicopter (LPH) is a term used by some navies to denote a type of amphibious warfare ship designed primarily to operate as a launch and recovery platform for helicopters and other VTOL aircraft.

Under the NATO Standardization Agreement (STANAG) document for reporting vessels, LPH is a short form designator used for "Amphibious Assault Ship, Helicopter" defined as a "large helicopter carrier" for carrying and deploying around 1,800 assault troops using its own aircraft, but for which use of landing craft is "not a principal function".

Regardless of the terminology, all vessels classified as an LPH possess essentially similar capabilities.

Prior to selling the vessel to the Brazilian Navy in 2018, the RN operated HMS Ocean as an LPH.

Following the British government's decision to withdraw its Harrier aircraft at the end of 2010, the former light fleet carrier HMS Illustrious also performed this role until decommissioning in 2014.
