The 29K was a self-propelled anti-aircraft weapon used by the Soviet Union, consisting of a 76 mm air defense gun M1931 mounted on a YaG-10 truck.

History
In 1934, the Design Bureau (KB) Plant No. 8, named after Mikhail Kalinin, received an order to install 76 mm air defense gun M1931 on the chassis of the three-axle YaG-10 truck. Production completed by the Yaroslavl Automobile Plant, due to their experience with creating the SU-8 (artillery). In August–September 1936, tests were carried out at the NIAP test site. The first vehicles entered service with Moscow Military District. ZSU 29-K took part in the parade on Red Square in Moscow. The first display of motorized anti-aircraft guns took place at a military parade in Moscow on 1 May 1934. Overall, sixty-one YaG-10 trucks were converted into 29K models. Modifications to the trucks included a reinforced undercarriage, rotating pedestal for the gun, and side boards replaced with semi-circular shields.
