To increase the armor protection without increasing the armor plate's thickness, and consequently its weight, face hardening the armor plates was common during the Second World War. It may damage the interior or the engine, cause the ammunition to explode, cause the fuel to catch fire, or injure the crew. Inversely, as the velocity of the shell decreases over range due to air resistance, so will the penetration capability.Īssuming the shell penetrates the armor of the tank being fired at, if the shell doesn't contains an explosive filler, it will essentially act as a large bullet. If the mass or the velocity of the shell is increased, so will the penetration capability of the shell. An AP shell is made from solid steel with a high carbon contents, which increases the hardness of the steel.Īrmor plate penetration is achieved by the kinetic energy of the shell. The earliest and most simple anti-tank shell was the basic armor piercing, or AP, shell. The descriptions below will give a brief overview of the main types of shells, explaining the basic designs, the method with which the shells penetrate an armor plate, and in which way they are designed to disable the tank against which they are fired. During the thirties and fourties, a large number of new shell types saw combat.
To be able to penetrate the armor of the tanks of potential enemies, it became necessary to design guns and shells for this specific purpose.
