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.

Contents

221 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 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 the Russian version of the same chassis - GAZ-AAA, and continued to be used in the BA-6. The biggest limitation of the BA-3 was the mobility, limited to roads or very hard ground, the result of unnecessarily [1] large weight. The innovation that slightly improved mobility was the auxiliary ("Overall") tracks that could be fitted onto the rear tandem wheels, converting the car to a half-track.

The BA-3 is externally very similar to the BA-6; the BA-3 had a door in the rear of the hull that was not present in the BA-6. [1] A more important improvement of the BA-6 was the new GK tires, filled with sponge (porous rubber), and thus much less vulnerable to small-caliber fire. On the downside, the tires reduced both the speed and range of the vehicle, despite it having somewhat thinner armor. BA-3/6 cars were superseded by the BA-10 model. All cars of this series were very heavily armed for the era; they could knock out other vehicles with ease, including tanks. However, their thin armor made them vulnerable to heavy machine gun fire and small caliber cannon fire.

A prototype railway BA-3ZhD variant was created in 1936, but was not accepted for production. The BA-6ZhD was produced in limited numbers.

Some 60 BA-6 cars were delivered to Turkey in 1935. [2] The BA-3/6 were used in combat in the Spanish Civil War, against the Japanese in the Battle of Khalkhyn Gol, in the Finnish Winter War, and against the Germans in the early stages of the Eastern Front. The German Army used a few AAC-1937, Spanish-built six-wheeled armored cars that were close copies of the BA-3/6 series.[ citation needed ] Later in the war, the BA-3/6/10 were replaced in the Red Army's heavy scout vehicle role by light tanks, such as the T-60 and T-70.

A few captured BA-3 cars were used by the Finnish army under the designation BAF A [3] (sometimes also BA-32-1), and captured BA-6 cars under the designation BAF B.

Variants

The BA-3 ZhD and BA-6 ZhD were designations for BA-3 & BA-6 cars that had been fitted with a rail kit consisting of hydraulic jacks and six railroad wheels. Limited numbers were produced. [4] [5]

The BA-6M, built in 1937-1938, weighed 4800 kg and featured a 10mm thick welded, conical turret. A 71-TK-1 radio and 50 hp GAZ-M engine were installed [6] [7]

The BA-9 was a lightened (4,300 kg) vehicle based on the BA-6M, built in 1936. The 20K gun was replaced by a 12.7mm DK machine gun (early version of the DShK) and a 7.62 Degtyaryov machine gun was installed in the hull. 100 were ordered, but production was dropped after two prototypes were completed due to the lack of DK machine guns. One prototype was sent to Moscow and the other to Leningrad. [8] [9] [10]

The BAZ was an experimental amphibious version of the BA-3. The welded hull was shaped like a boat and two sponsons were placed in the front. Two 389 cm brass screws were installed for use in water. [11]

The Kliment Voroshilov (KV) tanks are a series of Soviet heavy tanks named after the Soviet defence commissar and politician Kliment Voroshilov who operated with the Red Army during World War II. The KV tanks were known for their heavy armour protection during the early stages of the war, especially during the first year of the German invasion of the Soviet Union. In certain situations, even a single KV-1 or KV-2 supported by infantry could halt German formations. The German Wehrmacht at that time rarely deployed its tanks against KVs, as their own armament was too poor to deal with the "Russischer Koloss" – "Russian Colossus".

The BT tank was one of a series of Soviet light tanks produced in large numbers between 1932 and 1941. They were lightly armoured, but reasonably well-armed for their time, and had the best mobility of all contemporary tanks. The BT tanks were known by the nickname Betka from the acronym, or by its diminutive Betushka. The successor of the BT tanks was the famous T-34 medium tank, introduced in 1940, which would replace all of the Soviet fast tanks, infantry tanks, and light tanks in service.

<span class="mw-page-title-main">SU-76</span> Light self-propelled gun

The SU-76 was a Soviet light self-propelled gun used during and after World War II. The SU-76 was based on a lengthened version of the T-70 light tank chassis and armed with the ZIS-3 mod. 1942 76-mm divisional field gun. Developed under the leadership of chief designer S.A. Ginzburg (1900–1943). Its quite simple construction and multipurpose combat role made it the second most produced Soviet armored fighting vehicle of World War II, after the T-34 medium tank.

<span class="mw-page-title-main">T-44</span> Soviet medium tank

The T-44 was a medium tank first developed and produced near the end of World War II by the Soviet Union. It was the successor to the T-34, offering an improved ride and cross-country performance, along with much greater armor. Designed to be equipped with an 85 mm main gun, by the time it was fully tested the T-34 had also moved to this weapon. Both tanks offered similar performance, so introducing the T-44 was not considered as important as increasing T-34 production. Fewer than 2,000 T-44s were built, compared to about 58,000 T-34s. Although the T-44 was available by the end of the war, it was not used in any battle. It was 1 ton lighter than the T-34-85 and slightly faster. The T-44 was heavily influential on the design of the T-54/55 main battle tank, most notably the removal of side sloping, thick frontal armor, and a low profile. Also notable was the T-44-100, a 100mm D-10T-armed prototype, which would be the same 100mm gun mounted on the T-54/55, bar some minor changes.

The BA-64 was a Soviet four-wheeled armoured scout car. Built on the chassis of a GAZ-64 or GAZ-67 jeep, it incorporated a hull loosely modeled after that of the Sd.Kfz. 221. The BA-64 was developed between July and November 1941 to replace the BA-20 then in service with armoured car units of the Red Army. Cheap and exceptionally reliable, it would later become the most common Soviet wheeled armoured fighting vehicle to enter service during World War II, with over 9,000 being manufactured before production ended.
