Angthong was commissioned as part of the Thai navy's procurement of landing platform docks to expand its humanitarian assistance and disaster relief capacity following the
2004 Indian Ocean tsunami. 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. The
Angthong was deployed as a base of operations for the navy's humanitarian assistance mission during the
2015 Rohingya refugee crisis, and to provide disaster relief during flooding in Southern Thailand in January 2017. ==References==
