What kinds of heavy tanks did China and the United States have in World War II?

T 1 heavy tank is a kind of heavy tank developed by the United States during World War II, which was finally abandoned due to lack of maneuverability. After the outbreak of World War II, German tanks were invincible for some time. The US military began to consider the development of a new generation of heavy tanks, and the preliminary research of the new generation of heavy tanks began in September 1939. On May 20th of the following year, the US Army executives instructed relevant units to immediately develop a heavy tank with a total weight of 50-80 tons.

At that time, the US military decided to develop a multi-turret tank with two main turrets, each with a rotation angle of 250 degrees, and equipped with a 75mm T6 tank gun with low initial velocity. There are also two small turrets, one of which is equipped with a 37 mm gun and a 7.62 mm machine gun, and the other is equipped with a 20 mm gun and a 7.62 mm machine gun. Four machine guns were also installed on the spherical gun rack in the car. In July 1940, 1 1, the plan was passed, and the heavy tank numbered T 1 was given.

Second, T29 heavy tanks (not mass-produced into the army)

T29 is the project started in March of 1944; The American heavy tank project is used to fight against the new German heavy tanks. At that time, the 45-ton T26E3 was considered insufficient to counter the 70-ton German Tiger II tank. T29 didn't go to Europe, but it gave postwar engineers a chance to test the artillery engineering theory and some parts.

T29 heavy tank is considered as a widened version of T26E3 tank, with heavier armor and powerful Ford GAC engine, which can provide about 770 horsepower and make drivers more comfortable. There is also a 105mm T5 gun with high firing rate. T29 heavy tank weighs about 70 tons, which is equivalent to Tiger II tank in firepower and protection. Another experimental model has a V 12 engine.

The T30 heavy tank developed at the same time has a very close relationship with T29 heavy tank. T30 heavy tank is almost the same as T29 heavy tank except that it is equipped with 155mm gun, more powerful engine and semi-automatic loader.

Third, American M6 heavy tanks.

The first M6 tank rolled off the production line in February 1942, and * * produced 40 vehicles, including M6A2, 12 M6A 1 vehicle and M6 a 2 20 vehicle. Finally, 1 car was delivered in February 1944, and the prototype car, M6, was produced. The first M6 arrived at Fort Knox proving ground on 1943 65438+ 10/6.

The M6 series uses the same large turret. Turret diameter1.75m, leaving enough space for installing large caliber guns. The main gun is M7 76.2mm tank gun developed from M 192 1 76.2mm antiaircraft gun. It is also the main gun of the M 10 expulsion chariot. T35(M26 heavy tank) under development at that time also planned to use this type of gun. ?

Coaxial with M7 gun is M6 37mm gun used in M3 light tank. There is a coaxial machine gun under the 37 mm gun. The commander's control tower uses the same commander's machine gun tower as the M3 medium tank and is equipped with a 7.62mm machine gun. The prototype of M6 has a very special design. At 6 o'clock on the turret, that is, directly behind the turret, an air-to-air machine gun of 12.7 mm is installed, and the maximum elevation angle can reach 80 degrees. But it can't rotate independently, and the turret must rotate at the same time, so it has no practical use. This machine gun was removed when it was officially produced.

Extended data

Introduction of heavy tanks:

Before the 1960s, tanks were mostly classified into light, medium and heavy types according to the total combat weight and gun caliber. Usually, heavy tanks weigh 42 ~ 80 tons, and the maximum caliber of artillery is 152 mm, which is mainly used to support medium-sized tanks.

It is characterized by large caliber, long barrel and great attack power. Because the caliber of tank artillery is large, it means that the attack power is large. The caliber of heavy tank guns is 88 mm, 90 mm, 100 mm, 105 mm, 120 mm, 122 mm, 128 mm, 130 mm or even 65438.

At the same time, heavy tanks have thick armor and strong anti-shelling ability, but their heavy weight leads to slow speed. Heavy tanks have become the backbone of armored forces because of their huge shape and amazing weight. Heavy armor and powerful artillery make every heavy tank have the ability to fight independently.
