Ust-Katav Wagon-Building Plant

The factory was founded in 1758.

The plant built streetcars (trams) from 1901. The first tram was made for Tbilisi. In 1960, a special design bureau for streetcar transport design was established, and about 20 streetcar models were developed. The plant set a world record for producing one type of vehicle — the KTM-5, of which 14,991 units were produced.

Currently, the plant produces low-floor trams of different variations of models 71-623 and 71-631. In 2006, the plant built its first 71-630 low-floor articulated trams (tested in Moscow). In 2009, UKVZ offered two 71-623 partial low-floor, single-section vehicles for trial operation in Ufa and Nizhny Novgorod. In 2010, additional trams of these models were built for Moscow, Perm, Nizhnekamsk and Krasnodar. The plant also produces trim spare parts and provides tram maintenance services.

In addition to streetcars, the plant produces gas pressure regulators, pipeline valves, pumps and consumer goods.

By Presidential Decree of the Russian Federation number 772 of June 11, 2011, and Federal Decree number 1159-r of July 7, 2011, the Federal State Enterprise Ust-Katavsky Automobile Production Plant Kirov was renamed a branch of the Khrunichev State Research and Production Space Center.

In 2025 the design for a single section double-decker tram was unveiled. The car will be 16.8 m in length and 5.4 m in height.

H/M (1937–1941), two-axle tram. Production of this model was transferred from Mytishchi machine-building factory (now "Metrovagonmash"), where it was produced since 1927.

KTM-1/KTP-1 (1947–1961), two-axle tram with all-metal monocoque body.

KTM-2/KTP-2 (1958–1969), two-axle tram with a metal body.

KTM-5 (71-605; 1969–1992), four-axle tram with single-leaf sliding doors. Nearly 15,000 cars of this type were built, which allowed them to become the most widely produced tramcar in the world. They have been used in many tram systems in Russia are the only type of rolling stock in some of them.
