Description


Introduction

The 29-K is a pre-World War 2 era self-propelled anti-aircraft gun of Soviet origin. The 29-K was designed in the mid 1930's and entered service before World War 2. The role of the 29-K was to protect motorized and armored formations. It was not intended to fire on the move, but was to keep up with motorized formations and then quickly move into a firing position.

Design

The 76mm ordnance of the 29-K is derived from the main gun of the T-28 tank. It is mounted on a pedestal at the rear of an YaG-10 6x4 truck. The rear flatbed has two sides that fold down to make circular firing platform. The chassis is reinforces and four supporting legs are lowered in the firing position. The seats behind the cabin double as ammunition storage.

Firepower

The 29-K is armed with a 76mm 3-K anti-aircraft gun. This was produced in large numbers as a towed system. Firepower is similar to the towed system. Maximum rate of fire is 20 rpm for a short duration. The theoretical ceiling is over 9 km altitude. The 76mm 3-K can also be used in an emergency as a direct fire weapon against ground targets including armored vehicles and tanks. The 29-K is most effective when used with the associated mechanical firing computer mounted on a separate vehicle.

Mobility

The 29-K is based on the YaG-10 6x4 heavy truck. The chassis is reinforced and a turntable with circular wooden deck is installed. The YaG-10 truck contains various Western components such as a Hercules petrol engine, Brown manual gearbox and Moreland suspension. Maximum speed on road is 42 km/h.

Users

A total of 60 vehicles were produced in series. These participated in a parade on the Red Square in 1937. At first these were organized in 4 battalions with 5 batteries of 3 guns, plus associated fire control and search lights. In 1941 these were reorganized in 15 batteries of 4 guns dispersed over 5 battalions that also included 85mm towed anti-aircraft guns. Four batteries were allocated in October of 1941 for anti-tank defense around Moscow. Some of these may have been captured by Nazi Germany.
