Klimov. UEC-Klimov () is a Russian manufacturer of gas turbine engines, main gearboxes and accessory drive gearboxes for transport aircraft.

Originally established as Kirill Klimov Experimental Design Bureau in Saint-Petersburg under the direction of  (Влади́мир Я́ковлевич Кли́мов) (1892–1962), Klimov designed engines for Soviet aircraft based on Renault aircraft engine designs. It may have used the designation Aircraft Repair Factory (aviazavod, ARZ) 117 during the Soviet period.

History
The Klimov OKB was formed in the early 1930s to produce and improve upon the liquid-cooled Hispano-Suiza 12Y V-12 piston engine for which the USSR had acquired a license. At that time Klimov also manufactured motorcycles.

In 1946 the British government allowed Rolls-Royce to sell a number of Nene and Derwent V turbojet engines to the Soviet Union. Klimov OKB was given the task of "metrifying" the British designs, without the knowledge or permission of the West, as the VK-1 and RD-500.

Klimov United Engine Company is now located in Saint Petersburg.

It used the nationalised buildings originally erected by 1914 in the city's present-day Vyborgsky District for the joint stock Russian Renault automotive works, adding new workshop and administrative premises on the land in Bolshoy Sampsoniyevskiy Prospect avenue near the present Kantemirovskaya Street. By 2020 the premises have been vacated for redevelopment for a housing project.

Piston engines
 M-100 – Hispano-Suiza 12Ydrs built under license
 M-103 – improved M-100
 M-105 – improved M-103; redesignated as VK-105 in 1943
 M-110
 M-120 – prototype inline 18-cylinder with three M-103A blocks in an inverted Y configuration; cancelled due to engine malfunction
 During World War II, designations were changed from M (motor) to VK (the lead designer's initials)
 VK-106 (M-106 before March 1944) – prototype developed from M-105 with improved performance at lower altitudes; cancelled due to cooling problems
 VK-107 (M-107 before March 1944) - development of M-105 and VK-106 with four valves per cylinder and more power
 VK-108 – prototype version of VK-107 with 1850 hp on takeoff; never entered production
 VK-109 - 1945-1946 development of the VK-108 with water injection, intended for the Myasishchev VB-109
 VK-110 - based on VK-109, 2100 hp; only a project
 VK-150 - inline 24-cylinder concept, 3700 hp
