RFA Mounts Bay is a Bay-class auxiliary landing ship dock (LSD(A)) of the Royal Fleet Auxiliary, named after Mount's Bay in Cornwall. She is designed primarily for amphibious operations and logistical support. The vessel has a full load displacement of approximately 16,160 tonnes and measures 579.4 feet (176.6 meters) in length with a beam of 86.6 feet (26.4 meters) and a draught of 19 feet (5.8 meters). Propulsion is provided by two Wärtsilä 8L26 generators (6,000 horsepower) and two Wärtsilä 12V26 generators (9,000 horsepower), which drive two steerable propulsion pods, supplemented by a bow thruster. She can reach a maximum speed of 18 knots and has an operational range of 8,000 nautical miles at 15 knots. Mounts Bay's cargo capacity is substantial, capable of carrying up to 24 Challenger 2 tanks or 150 light trucks within 1,150 linear meters of space. She can also transport 200 tons of ammunition or 24 twenty-foot containers. Normally, she can accommodate 356 soldiers, with overload capacity increasing this number to around 700. Although not routinely armed, she can be fitted with defensive weapons such as two 30 mm DS30B cannons, two Mk.44 miniguns, six 7.62mm L7 GPMGs, and a Phalanx CIWS. Constructed by BAE Systems Naval Ships at Govan, Scotland, she was laid down on 25 August 2002 and launched on 9 April 2004 after a somewhat tumultuous launch that involved entanglement with chains and weights. She was officially dedicated on 13 July 2006, becoming the first of her class to enter service. Mounts Bay has participated in numerous operational deployments, including the 2006 Vela Deployment, Arctic exercises, and humanitarian missions such as supporting hurricane relief efforts in the Caribbean. She has also been involved in NATO exercises, maritime festivals, and search-and-rescue operations, including assisting in the search for EgyptAir MS804 and supporting EU operations against trafficking. Throughout her service, Mounts Bay has demonstrated versatility as a sealift and amphibious support vessel, capable of transporting vehicles, troops, and supplies across a wide range of operational environments. As of 2024, she continues to serve as a key asset in the Royal Navy's amphibious and logistical capabilities, including deployments to the Mediterranean and participation in NATO exercises. She is scheduled for a refit in early 2025.
