The Endurance class landing platform dock ships (LPD) are the largest class of ships in the Republic of Singapore Navy (RSN). They were designed and built by Singapore Technologies (ST) Marine to replace the old County class tank landing ships (LST). The four ships form the 191 Squadron of the RSN.
Planning and development[edit | edit source]
The navy's intention to purchase the Endurance class was revealed by former Defence Minister Dr. Tony Tan during his visit to Tuas Naval Base on 3 August 1996. These ships were to replace the five ex-United States Navy (USN) County class LSTs, which were acquired by Singapore from the United States in the 1970s. ST Marine was awarded the government contract to design and build the four ships – a significant milestone for the local defence and shipbuilding industries given the scale and extensiveness of the programme.
Construction of the Endurance began in early 1997, with the keel laid down at ST Marine's Benoi yard on 27 March 1997.

Design and construction[edit | edit source]
The Endurance class is 40% larger than the previous County class that she replaced but yet travels almost twice as fast. Each ship is fitted with a well dock which can accommodate four landing craft, as well as a flight deck which can accommodate two medium lift helicopters.
While the RSN describes the Endurance class as LSTs, they lack the beaching capability traditionally associated with LSTs and their well docks and flight decks qualify the Endurance class more as amphibious transport docks. The term "multipurpose support vessel" is closer to the intent of its use, given the necessary limited objectives of the RSN as a small naval force operating primarily in littoral waters.
The Endurance class was built with a heavy emphasis on automation. RSS Endurance became the first ship in the world to use official electronic navigational charts with the Electronic Chart Display and Information System (ECDIS) to circumnavigate the world. 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.
Operational history[edit | edit source]
The ships provide sea transportation for personnel and equipment for Singapore Armed Forces' overseas training, as well as a training platform for RSN's midshipmen. RSS Endurance became the first RSN ship to circumnavigate the globe when it participated in the 6th USN International Naval Review in New York City, passing through both Panama and Suez canals.
The ships actively participate in various multilateral exercises annually. RSS Resolution successfully fired a Mistral surface-to-air missile during Exercise Cooperation Afloat Readiness and Training in 2000, an annual joint naval exercise between the USN and RSN. RSS Endurance participated as both a compliant and non-compliant vessel for boarding teams during Exercise Sea Sabre in 2004 as part of the Proliferation Security Initiative.
The ships are active participants in multinational peacekeeping efforts. As part of Singapore’s contribution to the reconstruction efforts in Iraq, RSS Endurance was sent to the Persian Gulf in October 2003 for two months. RSS Resolution followed in November 2004 and RSS Endeavour in February 2006. The ships conducted logistical tasks, such as replenishing supplies for other naval vessels in the Persian Gulf, and conducted patrols to enforce maritime presence. They also served as a platform for helicopter missions and maritime boarding operations missions by teams from other coalition countries when they inspected ships leaving Iraq. The last deployment saw the RSS Resolution taking on the expanded role of taking charge of coalition and Iraqi Navy ships to defend Iraq's oil platforms. On 1 September 2007, RSS Persistence became the fourth ship to be deployed to the Persian Gulf in support of the multinational reconstruction efforts in Iraq. RSS Resolution was subsequently tasked for RSN's fifth deployment to the Gulf on 30 August 2008.
The ships were also involved in various humanitarian relief operations, such as the tsunami-hit Indonesian province of Aceh in 2004. Within a few days of the disaster, the RSS Endurance sailed to Aceh in Indonesia to deliver emergency supplies and medical personnel to aid in the relief efforts. She was then joined by RSS Persistence on 4 January 2005 and RSS Endeavour on 16 January.
On 12 February 2009, Minister of Defence Teo Chee Hean announced that RSS Persistence would join other naval forces off the coast of Somalia for three months in 2009. Comprising an LST with two Super Puma helicopters on board, the Singapore Armed Forces Task Group has been conducting daily helicopter surveillance flights and sector patrols to deter and disrupt piracy activities. The ship worked with the multinational Combined Task Force 151 to protect shipping in the Gulf of Aden. Since then, two additional SAF task groups have been deployed to the Gulf of Aden, RSS Endurance from June to October 2010 and RSS Endeavour from August 2011.
Export[edit | edit source]
On 11 November 2008, a SGD 200 million contract was signed between ST Marine and Thailand for the sale of one unit of the Endurance class LPD and its associated landing craft. The LPD would use the Terma C-Series system, which includes the C-Flex combat management system, C-Search radar suite which includes the Scanter 4100 radar and IFF, and the C-Fire fire control system.
On 21 March 2011, the new ship was christened HTMS Angthong (pennant number LPD-791) and was launched from ST Marine's dockyard by the wife of Admiral Khamthorn Pumhiran, Commander-In-Chief of Royal Thai Navy (RTN). The delivery of the ship was completed on 19 April 2012.
