Founded in 1939 as Aircraft Repair Plant No. 99, the Ulan-Ude plant moved from wartime aircraft repair and fighter production into helicopter manufacturing in the Soviet period. Its public company history describes production across Soviet design bureaus, including Kamov coaxial helicopters and Mil's Mi-8 family.

For the WeaponsOfConflict catalog, the plant matters chiefly as one of the industrial sources behind Mi-8/Mi-17-family utility and transport helicopters. The plant reports that Mi-8AMT/Mi-171, Mi-8AMTSh/Mi-171Sh, Mi-171A2, and related support and training work form the center of its current production role.

The enterprise is wholly owned by Russian Helicopters, which is part of Rostec. Public sanctions datasets identify Joint Stock Company Ulan-Ude Aviation Plant as a sanctioned Russian defense-industrial entity, so sourcing for current ownership and legal names is split between official Russian pages and sanctions records.
