Angthong (LPD-791) is a Royal Thai Navy amphibious ship based on the design of Endurance-class landing platform dock of the Republic of Singapore Navy.

Development

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.[2][3]

Construction and career

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.[4][5] 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.[6]

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.[7][8]
