Yan Nyein Aung-class submarine chaser (Project PGG 063) also known as 63m stealth submarine chaser is the first indigenous stealth submarine chaser class of the Myanmar Navy. The lead ship of the class is UMS Yan Nyein Aung (443) and she was commissioned with UMS Yan Ye Aung (446) on 24 December 2020. This class is intended to replace the ten old Hainan-class submarine chasers.[1][2][3][4]
Design and description[]
The early design of the Yan Nyein Aung-class submarine chaser
The hulls of the ships are constructed of steel and their superstructures of aluminium to reduce the ship's displacement. The uniqueness of this class is that the ships are equipped with three waterjet propulsers to secretly track and attack submarines and to improve maneuverability by reducing noise produced from the engines and propellers. The basic purpose of this class is to quietly track and destroy submarines in the country's exclusive economic zone. They can also carry out various constabulary tasks within country's maritime boundary against maritime terrorism, environmental pollution, smuggling and can also be deployed for search and rescue operations and transportation of aids when necessary.
Armament[]
Type-66 57 mm twin AA guns and 2M-3M 25 mm twin AA guns of UMS Yan Ye Aung
The ships of this class are equipped with one Type-66 57 mm semi-automatic twin gun, two 2M-3M 25 mm twin guns and two locally made QJG-02G 14.5 mm guns for anti-aircraft warfare. Armament for air defense role may seem weak, but this category does not need much because this class focuses only on the anti-submarine role.
Triple torpedo launchers fitted on the left side of UMS Yan Ye Aung
The ships are also equipped with two triple torpedo launchers for Shyena torpedoes, two RBU-1200 ASW rocket launchers and two LDC (large depth charge) throwers and naval mines as the anti-submarine weapons (ASW).[5][6]
History[]
Project PGG 063 was approved at the 31st council meeting of Myanmar Navy.The construction of the lead ship, UMS Yan Nyein Aung was started in March 2016 and she was launched in March 2019. UMS Yan Nyein Aung (443) was commissioned with UMS Yan Ye Aung (446) on 24 December 2020.[7][8][9][10]
