UMS Minye Theinkhathu (71) (Burmese: မင်းရဲသိင်္ခသူ; [mɪ́ɴjɛ́ θèiɴgəðù]) is a Sindhughosh (Kilo)-class submarine owned by the Myanmar Navy. It is the first of two submarines procured by the country's navy, followed by the UMS Minye Kyaw Htin.[3] Before being acquired by Myanmar, it served in the Indian Navy as INS Sindhuvir (S58) (Brave at the Sea).[4][5]

Background

Beginning in the 1980s and ending in 2000, the Indian Navy acquired ten Kilo-class submarines from the Soviet Union and its successor state Russia. Within India, they are known as the Sindhughosh class.[6]

Myanmar Navy service

Myanmar acquired Sindhuvir in 2020.[7][8][9] The ship was refitted by Hindustan Shipyard before the handover.[10][7]

The submarine was first seen publicly as a Myanmar Navy ship, as UMS Minye Theinkhathu, on 15 October 2020 as part of a naval fleet exercise (‘Bandoola 2020’).[9] The submarine was formally commissioned along with other six new ships at the 73rd Navy Day ceremony on 24 December 2020.[11][12] The ceremony was attended by the Indian and Russian ambassadors to Myanmar, which the military intelligence company Jane's believes could indicate Russian involvement in the submarine's transfer to Myanmar.[12]

It appears to be named after Minye Theinkhathu of Toungoo (Taungoo), who was the father of King Bayinnaung and served as viceroy of Toungoo from 1540 to 1549.[citation needed]

The Minye Theinkhathu was in naval exercises alongside the Minye Kyaw Htin on July 6, 2022 in the Bay of Bengal.[13]
