A version of the M4A3 also appeared, armed with a 105 mm howitzer and powered by a Ford GAA engine with a capacity of 450 HP. Another - M4A2 - had welded armor and a new General Motors 6460 engine with 375-410hp, but much less prone to fire. Chronologically the first was the M4A1 version that already had a cast armor. Many development versions were created in the course of serial production M4 Sherman. At the same time, however, a tank was created that could be truly large-scale production and had a significant modernization potential. The result was a tank with good armament for 1942 and early 1943, average armor, but with a tilted front plate, but also with poor maneuverability and - especially in the first versions - very susceptible to fire as a result of hitting the engine compartment. A significant role was also played in the mass production of the new tank and the lowest possible production costs. Only possible clashes with the carts were assumed Pz.Kpfw III and Pz.Kpfw IV. When designing the M4 Sherman, the emphasis was primarily on playing the role of an infantry support vehicle, and not fighting enemy tanks - this was the role of American tank destroyers. First of all, it only used a slightly changed chassis of the M3 Lee car. The M4 Sherman was developed as the successor to the M2 and M3 tanks, although it used many of the latter's components. The vehicle was armed with - depending on the version - a single 75mm M3 cannon or a 76mm M1 cannon or a 105mm M4 howitzer and two 7.62mm Browning1919A machine guns.

The M4 Sherman was powered by a single engine version of the M4A1 Continental R 975 C4 with a power of 400 hp. In total, about 49,000 copies of this tank of all versions were created, which makes it one of the most produced tanks of the Second World War and the most important tank in the equipment of the Allied armies during this conflict.

The first prototypes were built in 1941, and serial production was carried out in the period 1942-1945. The M4 Sherman was an American medium tank from the Second World War.
