BA-20 - Soviet light armored vehicle 1930. Designed on the chassis of the car GAZ-M1 as a light armored vehicle for the exploration, Communications and escort of the Red Army, serially produced with 1936 by 1942 year in several variants.
The armored car was produced from 1938 by 1941 inclusive (a small number of cars BA-20 has been released at the beginning of 1942 Year of the remaining backlog of parts). It was created on the chassis of the car GAZ-M1, are mass-produced with 1936 of the year. Housing welded from rolled armor plates. Fighting compartment housed at the rear of armored. The turret is mounted in a ball bearing installed 7.62mm gun. Acceptable gun elevation angle in a spherical support was 23 degrees, decrease – 13 degrees.
In armored car bulletproof tires were installed, filled with spongy rubber GK. As used radio communication means 71 TK-1 with handrail antenna, which in the course held in 1938 year modernization was replaced by whip. The machine is widely used in the Red Army as a commander of intelligence, Communications and outposts. There was also developed a version for traffic by rail at a speed of 80 km / h.
AT 1936 year on the basis of a two-axle passenger car GAZ-M1, releases at the Gorky Automobile Plant from the same year, Vyksa plant began mass production of the BA-20 armored cars, which lasted until the beginning of the Great Patriotic War. This light armored vehicle, as well as its modernized version of the BA-20M, It has become the most massive wheeled combat vehicle of the Red Army. Armored vehicle BA-20 was built on the assembly scheme with front engine and rear – the crew compartment, the front wheels are manageable, rear – leading.
Fully welded closed housing armored BA-20 was made of a rolled steel sheets of thickness from 4 mm to 6 mm, which were installed on the sides with small angles. At the windshield and the rear plate, this angle was significantly greater, which increases their bulletproof. Such a reservation is provided protection crew, which consisted of two people, by conventional bullets, issued by a distance 80-100 m. For entry and exit of the crew out of the car in the sides had a rectangular door with external hinges. At the bottom of the sheet feed had bracket, which were mounted spare wheel.

The armored car driving compartment, located behind the engine compartment, the left is the driver's seat, handle it – seat vehicle commander. Provided an overview of the two frontal window, bronekryshkami equipped with observation slots, and two peepholes in the side doors. On the back of the housing roof was installed conical tower circular rotation with a small cupola, who was a cover of the tower hatch and opening recline. In the frontal towers in ball mount was mounted 7.62-mm machine gun DT, suggests the target in a vertical plane in the sector from -13 ° to + 23 °. Ammunition to it consisted of 1386 rounds. Rotating turret carried out manually by a mechanical actuator.
In front of the housing in the engine compartment has been installed inline four-cylinder petrol engine liquid cooling GAS-M1, develops power 36,7 kW (50 l. from.), allowing the armored vehicle to move on roads with a hard surface with a maximum speed 90 kmh. At full refueling BA-20 armored car could go from 270 to 350 km depending on the road.
Light armored BA-20 before being sent to the front. The first row consists of machines, 71 equipped with radio-TK-1 with handrail antenna.
Access to the engine and its nodes for repair and maintenance provided hinged cover upper part and leans upward bronekapota operating hatches in the sides of the engine compartment. In front of the last broneliste, stamped letters in the form of a wide V, There were two movable flap on the hinge, are controlled inflow of cooling air to the radiator and the engine. In a combat situation bronestvorki closed, to prevent radiator damage bullets and shrapnel shells and mines. air circulation in the engine compartment provided narrow movable panel, which was located behind the hinge lid bronekapota.V zadneprivodnoy (4×2) chassis with reinforced suspension with semi-elliptic leaf springs used wheels with bulletproof tires GK, filled with spongy rubber. Front and rear wheels covered wings streamlined, which are meshed with the bottom of the footrest, forming a whole with it. On the bandwagon ahead of the rear wings were mounted boxes with spare parts and tools.
Due to incomplete drive armored BA-20 had limited permeability when driving on rough terrain. Its traction is also poor – the machine can overcome the rise with a slope no more than 15 °. For movement in the dark armored vehicle was equipped with headlights, mounted on the front wings on either side of the engine compartment front plate.
Podbityi AND 20
In the standard equipment reconnaissance armored BA-20 included 71 radio-TK-1 and handrail antenna, mounted on brackets around the body at roof level. AT 1936 year version of armored vehicles was built for movement by rail. This modification, received the designation BA-20zhd, during combat weight 2.78 T developed on rails speed 80 km / h and had a cruising range 430-540 The crew of the BA-km 20zhd consisted of three people.
Upgraded version of the BA-20M appeared in 1938 year and differed from the base of the machine a new turret conical shape, presence of the additional fuel tank and a new radio station 71-TC-3 Correspondingly, instead handrail whip antenna was installed. With a crew of three combat weight of BA-20M has increased to 2,52 tonnes, which is no good effect on the suspension and terrain armored car. The maximum speed of the machine fell sharply and amounted to only 50 kmh.
Armored cars BA-20 and BA-20M consisted of the Red Army and took part in the fighting on Khalkhin Goal, of KVZHD, and then to the Great Patriotic War.
In summer 1941 , German troops captured about a hundred armored cars BA-20 and BA-20M. Trophy car hit the police units and the SS troops under the symbol BA 20(r) and BA 202(r) respectively. armored VA 202(r) They were in service of different parts, including 741 Mountain Volunteer SS Division “prince Eugen”. Bronevyky BA-20zhd, adapted for movement on railway tracks, Germans were used as reconnaissance vehicles as part of some armored trains, operating on the Eastern Front.
