UMS Minye Theinkhathu
1987 Sindhughosh-class submarine
UMS Minye Theinkhathu (71) (Burmese: မင်းရဲသိင်္ခသူ; Burmese pronunciation: [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. Before being acquired by Myanmar, it served in the Indian Navy as INS Sindhuvir (S58) (Brave at the Sea).
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.
Myanmar Navy service
Myanmar acquired Sindhuvir in 2020. The ship was refitted by Hindustan Shipyard before the handover.
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’). The submarine was formally commissioned along with other six new ships at the 73rd Navy Day ceremony on 24 December 2020. 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.

Why this record matters
A short description can identify a subject without explaining its stakes. For “UMS Minye Theinkhathu”, the useful work is to connect “1987 Sindhughosh-class submarine” to the records capable of establishing context and consequence.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Feb 9, 2026. The linked authority identifier is Q5972692. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2000 and 2020.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
