Char B1 (FR.Char de bataille B1) - French heavy tank of the 1930s. It was developed since 1921, but was adopted only in March 1934. It was actively used in battles with German troops in May-June 1940, despite the hefty archaic design, showing excellent security.
B1 had a layout with the location of the main armament in the frontal part of the hull, and the auxiliary one in a rotating turret. The engine and transmission were located at the rear of the tank. The tank's crew consisted of four people: a driver-mechanic, who also performed the functions of a gunner from the main gun; loader of both guns; radio operator and tank commander, who was also a shooter and partly loader of 47-mm guns.
The initial version of the B1 tank used the 75 mm SA35 gun as the main armament. The small turret was equipped with a 47 mm short-barreled SA34 gun, which was ineffective against tanks with more than 20 mm armor. And after the release of a batch of 35 units, B1 was modernized. Improved tanks
the designs were named B1 bis. This was the most massive version, produced since 1937.
The tank received a new APX 4 turret with a new long-barreled 47 mm SA35 gun. The hull armor was increased to 60 mm, a more powerful engine (307 hp) and additional fuel were installed. In this case, the tank itself was assembled from cast parts. Another innovation was the use of a hydraulic booster.
The main armament of the Char B1 bis tank was a 75 mm semi-automatic gun, model 1935.
with a barrel length of 17.1 caliber. For live fire, shots of two types were used - high-explosive fragmentation and armor-piercing, the initial speed of which was 500 and 470 m / s, respectively. The main purpose of the Canon de 75 mm SA 35 gun was to shoot at enemy manpower and destroy light field fortifications.
Two 7.5 mm machine guns produced by the State Arsenal in Chatellerault were used as auxiliary weapons. According to the Char B1 bis service manual (1939), the machine gun ammunition consisted of 5,100 rounds.
The tank required good maintenance and many tanks were out of order on the way to the front.
The powerful 60 mm armor was not penetrated by any German tank. A long-barreled 47 mm gun penetrated all German tanks of that time. A total of 365 B1 bis units were produced.
