Aviation Support and Primary Casualty Reception Ship

Originally constructed as a container vessel for commercial proprietors, she was commandeered for duty during the Falklands Conflict in 1982. Following this, she was acquired and modified for her new function as an aviation support ship. After undergoing comprehensive trials, she commenced service, taking the place of the smaller RFA Engadine. She was deemed "usafe to sail" as of 2025 and retired from service. She has been in commission since 1988 (and still technically is as of March 2026, even though preparations are taking place for her scrapping).

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. She was in RFA commission from 11 April 2024 (entry into RFA service) to 21 July 2025 (entry into RN service).
