BA-6装甲車–徒歩約

The BA-3 (Russian: Broneavtomobil 3) was a heavy armored car developed in the Soviet Union in 1933, followed by a slightly changed model BA-6 in 1936. Both were based mostly on BA-I, the most important development being the new turret, same as in the T-26 m 1933 and BT-5 tanks, and also equipped with the 45 mm main gun. Around 180 BA-3 cars were built at the Izhorskij and Vyksunskij factories, until production ended in 1935. BA-6 followed with 386 cars produced between 1936 and 1938 in Izhorskij factory. Most of BA-3 production was based on the Ford-Timken chassis, a 6×4 modification of the US Ford AA 4×2 truck, but the last batch was built on Russian version of the same chassis – GAZ-AAA, continued to be used in BA-6. The biggest limitation of the BA-3 was the mobility, limited to roads or very hard ground, the result of unnecessarily large weight. The innovation that slightly improved mobility were the auxiliary (“Overall”) tracks that could be fitted onto the rear tandem wheels, converting the car to half-track.
