OAO Kuznetsov. Production of rocket, aviation and ground propulsion systems.
OJSC Kuznetsov is the leading engine building company in Russia. Here we design, manufacture and repair missile, aviation and gas turbine units for the gas industry and energy.
With these engines, the Vostok, Voskhod, Soyuz manned spacecraft and Progress automatic transport cargo space vehicles were launched. 100% of manned space launches and up to 80% commercial are produced using engines RD107 / 108 and their modifications made in Samara. The production of the plant is of particular importance for maintaining the combat readiness of long-range aviation in Russia. At Kuznetsov, the NK-12 engines for the Tu-95MS, NK-25 long-range bombers for the Tu-22М3 and NK-32 bombers for the unique Tu-160 bombers were designed, manufactured and serviced.
Today, the Samara enterprise is faced with the task of restarting the production of NK-32 02 engines, increasing the production volumes of rocket engines, increasing the reliability of industrial engines for Gazprom, and developing promising aviation developments.

The Kuznetsov enterprise, which is part of Rostec State Corporation, united several large Samara factories. At first they were engaged in the production and maintenance of engines for Vostok and Voskhod rocket carriers, now for the Soyuz. The second direction of the work of Kuznetsov today is powerplants for aircraft.
OAO Kuznetsov is part of the United Engine Corporation (UEC).
