| Source measurement | The integrated bridge system allows the operator to access the navigation and communications systems, the ECDIS and other vital systems needed to sail the ship effectively, while the Ship Control, Monitoring and Management System controls, monitors and manages most of the platforms on board. The ships are also equipped with an Aircraft Ship Integrated Secure and Traverse (ASIST) system which helps in landing, securing, manoeuvring and traversing a helicopter, and eliminates the need for deck personnel to secure helicopters upon landing. All these result in a high degree of automation, with a reduced manning requirement of 65 crew members for a 6,500-tonne ship.[source]Endurance-class landing platform dock · Design and construction; only the objects and conditions stated in this passage As Singapore is interested in acquiring the F-35B STOVL fighter aircraft, it is thought that such an LHD could be used as a light aircraft carrier . The STOVL F-35B needs a minimum of 168 m (551 ft) of runway to take off. It is thought that Singapore would need one to maintain sea lines of communication, as well as cope with fewer air bases in the future. However, operating the F-35B would incur greater procurement and operating costs compared to the conventional takeoff variants and greater fuel consumption needed for vertical landing, which could result in fewer aircraft being purchased. The design of the Endurance class would also have to be considerably revamped with a larger space to operate and store fixed-wing aircraft with a larger elevator and a ski ramp.[source]Endurance-class landing platform dock · Design and construction / Proposed landing helicopter dock variant; only the objects and conditions stated in this passage The Endurance-170 , a further development of the LHD variant, has been offered to the UAE Navy . It would have a full load displacement of 19,000 tons. New features include a 76mm gun, vertical launching systems , RAM close-in weapon systems , and a hangar able to accommodate up to 10 medium-sized helicopters.[source]Endurance-class landing platform dock · Design and construction / Proposed landing helicopter dock variant; only the objects and conditions stated in this passage In December 2014, Persistence was deployed in the search for Airasia Flight QZ8501 after it crashed into the Java Sea on 28 December 2014; along with the RSN ships Supreme , Valour , and Kallang , MV Swift Rescue , and two Lockheed C-130H Hercules .[source]Endurance-class landing platform dock · Operational history; only the objects and conditions stated in this passage | The Bay-class ships have a full load displacement of 16,160 tonnes (15,900 long tons) in RFA service; this increased slightly to 16,190 tonnes (15,930 long tons) after modifications for RAN service.[source]HMAS Choules · Design and construction; only the objects and conditions stated in this passage Largs Bay / Choules is 579.4 feet (176.6 m) long, with a beam of 86.6 feet (26.4 m), and a draught of 19 feet (5.8 m).[source]HMAS Choules · Design and construction; only the objects and conditions stated in this passage Propulsion power is provided by two Wärtsilä 8L26 generators, providing 6,000 horsepower (4.5 MW), and two Wärtsilä 12V26 generators, providing 9,000 horsepower (6.7 MW).[source]HMAS Choules · Design and construction; only the objects and conditions stated in this passage Maximum speed is 18 knots (33 km/h; 21 mph), and the Bay-class ships can achieve a range of 8,000 nautical miles (15,000 km; 9,200 mi) at 15 knots (28 km/h; 17 mph).[source]HMAS Choules · Design and construction; only the objects and conditions stated in this passage Largs Bay was fitted for but not with a Phalanx CIWS and a 30mm DS30B cannon when required for self defence.[source]HMAS Choules · Design and construction; only the objects and conditions stated in this passage The cargo capacity is equivalent of 200 tons of ammunition, or 24 twenty-foot equivalent unit containers.[source] |

During normal conditions, a Bay-class ship can carry 356 soldiers, but this can be almost doubled to 700 in overload conditions.[source]HMAS Choules · Design and construction; only the objects and conditions stated in this passage

Four months after entering service, an engine room fire resulted in steering and propulsion issues, requiring Largs Bay to be towed to Plymouth for repairs. In late November 2007, Largs Bay embarked 815 Naval Air Squadron 215 Flight and left home waters for the Caribbean to conduct counter-drug operations. She visited eleven islands including Barbados , Curaçao , Grand Turk , Martinique , Trinidad and also the USA. Three days after leaving Barbados Largs Bay ' s patrolling helicopter spotted a small fishing vessel stopped in the water and detained her after a pursuit; 575 kilograms (1,268 lb) of cocaine were recovered, with an estimated £20 million European street value. She participated in Navy Days while in port at Curaçao, where several hundred people toured her.[source]HMAS Choules · Operational history / United Kingdom; only the objects and conditions stated in this passage
In early 2010, Largs Bay was deployed to the Arctic Circle. Following the 2010 Haiti earthquake , the ship was pulled from exercises and sailed on 3 February to deliver a load of relief supplies to Haiti. On 18 February 2010, she arrived at Port-au-Prince and unloaded 430 tonnes (470 tons) of supplies plus 165 tonnes (182 tons) of rations, while engineers from the ship began work on restoring electricity ashore. On 30 March 2010, she returned home. Largs Bay ' s actions were recognised in December 2011 with the awarding of the Firmin Sword of Peace .[source]HMAS Choules · Operational history / United Kingdom; only the objects and conditions stated in this passage
For a short time from July 2013, Choules was anchored offshore of the Manus Regional Processing Centre in Papua New Guinea to provide temporary accommodation for Department of Immigration and other personnel, due to a lack of accommodation at the centre. In April 2015, the ship transported 46 Vietnamese asylum seekers back to Vũng Tàu , after their vessel was intercepted at sea on 20 March by Australian border protection units and their claims were rejected after interviews at sea lasting less than 40 minutes.[source]HMAS Choules · Operational history / Australia; only the objects and conditions stated in this passage
Choules was deployed to Vanuatu on 30 September 2017 to aid in the rescue of 11,000 people from a volcanic eruption of Monaro Voui.[source]HMAS Choules · Operational history / Australia; only the objects and conditions stated in this passage
