UMS Minye Theinkhathu (71) (Burmese: မင်းရဲသိင်္ခသူ; [mɪ́ɴjɛ́ θèiɴgəðù]) is a Sindhughosh (Kilo)-class submarine owned by the Myanmar Navy. It is the service's first and, as of 2021^[update], only serving submarine. Before being acquired by Myanmar, it served in the Indian Navy as INS Sindhuvir (S58).

Background[edit]

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.^{[citation needed]}

Myanmar Navy service[edit]

Myanmar acquired Sindhuvir in 2020.^[2]^[3]^[4] The ship was refitted by Hindustan Shipyard before the handover.^[5]^[2]

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’).^[4] The submarine was formally commissioned along with other six new ships at the 73rd Navy Day ceremony on 24 December 2020.^[6]^[7] 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.^[7]

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]}
