Autonomous Minehunting Mothership

The vessel commenced its existence as the offshore support ship MV Island Crown; however, in 2023, it was acquired by the Ministry of Defence and subsequently underwent a conversion at HMNB Devonport to adapt it for the specific purpose of supporting mine hunting. She transferred from the RFA to the Royal Navy in 2025. [4] [5]

Forward Repair Ship

Diligence was initially chartered for service during the Falklands War. She became a fleet maintenance vessel and was used in multiple forward deployments, including during both Gulf conflicts: Gulf War and Iraq War. [6]

Aviation Support / Training Ship

In 1964 a request was made for a helicopter support vessel designed to transport either 3 x Westland Wessex or 4 x Westland Wasp helicopters, along with the essential spare parts and equipment required for secondary line maintenance. [7]

Aviation Support Ship

Reliant was called into service during the Falklands Conflict in 1982, and the subsequent year, she was contracted for conversion into an aviation support vessel, becoming fully outfitted for her specialised function as an Aviation Support Ship. [8]

Salvage Vessels

King Salvor class

The King Salvor-class salvage vessels were a series of twelve ocean salvage vessels operated by the RFA. [9]
