In 1934, the Design Bureau (KB) Plant No. 8 [ru], 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 [ru]. 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[2] 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.[3] 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.[4]
