How do tank shells work?

At its nose, the round has an extended impact sensor. When the impact sensor collides with a target, it ignites an explosive, which melts surrounding copper. A shape charge liner concentrates the molten metal and hot gases into a narrow blast that cuts through the armor.

How much does a 120 mm tank shell weigh?

Armament: 105mm gun (the M1A2 has a 120mm), each shell weighs about 40 lbs. Armor: The composite armor used in the M1 is Chobham (after Chobham, England, where it was developed) or code-named Burlington.

How much does a 120mm Apfsds weigh?

41.1 lbs.

What is the strongest tank round?

The M829A1 round weighs 20.9 kg (46 lb) and has an overall length of 984 mm (38.7 in). The 7.9 kg (17 lb) of JA-19 propellant creates a chamber pressure of 5,600 bars (81,221 psi), which results in a muzzle velocity of 1,575 m/s (5,170 ft/s).

How fast is a tank shell mph?

How thick is a tank’s armor?

The need for greater firepower and more protection was apparent by 1941, so newer versions were given a 50-mm gun and fitted with armour 30–50 mm thick.

HESH rounds are still carried today by armoured engineer vehicles; they are typically intended for use against fortifications rather than armoured fighting vehicles. A 165 mm HESH round is used by the United States Army for the main gun of the M728 Combat Engineer Vehicle, an M60 tank equipped with a bulldozer blade.

Do Abrams tanks have AC?
