Albion-class landing platform dock

To cut the running costs of the Royal Navy, the 2010 Strategic Defence and Security Review concluded that one of its two Albion-class LPDs should be placed into extended readiness, or uncrewed reserve, while the other is held at high readiness for operations. The vessels will alternate between extended readiness and high readiness throughout their service lives.[10]

It was confirmed that Albion would be the first of the two vessels to be placed at extended readiness, for a cost of £2.5 million, as Bulwark had recently finished a major refit. Running costs while in extended readiness are estimated to be £300,000 per annum to keep the vessel available for reactivation at short notice. HMS Albion re-entered high readiness when HMS Bulwark was put into extended readiness. In 2014 Albion entered a regeneration refit and rejoined the active fleet in 2016. The running costs of one of the Albion-class vessels at high readiness ranged from £17.7 million to £38.6 million per annum from 2007 to 2011. As of late 2018 Albion was in active service while Bulwark was held at extended readiness.[11]

For defence against missile attack, the Albion-class LPDs were fitted with two 30 mm Goalkeeper CIWSs mounted fore and aft on the superstructure and two 20 mm cannon located on the forward superstructure. Defensive countermeasures include the Outfit DLJ decoys, eight Seagnat radar reflection / infra-red emitting decoy launchers and a BAE Systems DLH off-board decoy.[12] In 2017, Albion had her Goalkeeper mounts removed and replaced by a pair of 20mm Phalanx mounts as part of her refit prior to returning to active service; Bulwark will have her Goalkeeper mounts removed upon her entry into Extended Readiness.

When commissioned, the ships were fitted with two Kelvin Hughes Type 1007/8 I-band radars, for navigation and aircraft control. For air and surface search, a Selex Sensors and Airborne Systems Radar Type 996 E/F band radar was fitted. From 2013 on, RT996 will be gradually replaced by the BAE Systems Maritime Services Artisan 3D E/F-band (designated RT997). HMS Iron Duke was the first Royal Navy ship so fitted; RT997 will be fitted to Albion and Bulwark by 2015.[12] There is also an ADAWS 2000 combat data system and a UAT/1-4 Electronic support measures (ESM) system.[9]

HMS Albion was launched at Barrow-in-Furness on 9 March 2001.[8] After completing sea trials, Albion was commissioned in June 2003 and became fully operational in April 2004. Her home port is HMNB Devonport on the south coast of England.[7]

In December 2010, it was announced that Albion would be the next Royal Navy flagship after HMS Ark Royal.[17] She was deployed with the Response Force Task Group to the Gulf of Sidra off Libya to assist the ongoing NATO-led operation, and then moved into the Indian Ocean in June 2011 to assist with anti-piracy operations off the Horn of Africa. In 2011 she entered a state of "extended readiness".[18] In July 2017, she re-entered active service after a long re-fit.[19] While remaining deployable if required, in July 2023 she entered reduced readiness (skeleton crew aboard for ship maintenance).[20][21]

HMS Bulwark, the second in the class, was launched at Barrow-in-Furness in November 2001, and was commissioned in December 2004.[7]

One of Bulwark's first missions was Operation Highbrow in the Mediterranean in July 2006. Docking in Beirut, the ship evacuated around 1,300 United Kingdom nationals. In May 2010, she entered dry-dock at HMNB Devonport for a £30 million refit.[7] In October 2011, Bulwark, having just completed an eight-month refit, became the flagship of the fleet.[7][22] The refit improved her machinery and magazines, converted her to full night-vision tactical ability for landing craft and aircraft, and gave her the ability to operate two Chinook helicopters from the flight deck at the same time.[7]
