Why Are tank barrels not rifled?
The majority of modern tanks are fitted with smoothbore guns, which do not utilise rifled barrels in order to impart spin to projectiles as they are fired (see Annex B). HESH ammunition is used both as a general-purpose high explosive projectile, and also against other tanks and armoured vehicles. …
What happens if a gun has no rifling?
Shotgun A shoulder-fired long gun with no rifling in the barrel, designed to shoot a large number of small projectiles (“shot”) rather than a single large projectile (“a bullet”). Machine gun A machine gun is a fully-automatic firearm. Semi-automatic operation requires a pull of the trigger to fire each cartridge.
Why is the Abrams tank smoothbore?
The reason tank guns are smoothbore is the switch from HEAT (High Explosive Anti-Tank) to kinetic energy rounds sabot as the primary anti-tank round. Kinetic energy rounds are subcaliber rounds (smaller than the bore) and aren’t effective if the spun by rifling.
What happens when a round hits a tank?
This means that when the round hits something the explosives spread out into a disc on the surface and is then set of after a short delayed. This creates a shockwave that can cause the armour to fracture and break apart inside the tank sending shrapnel throughout the interior killing/ injuring the crew and damaging equipment.
Why are rifled barrels less accurate than smoothbore barrels?
Because of that “should be”. Turns out that rifled barrels are less accurate than a smoothbore when you’re using Fin Stabilized Sabot ammo. Spinning up a fin stabilized sabot round destroys its accuracy.
Why doesn’t tank ammo spin like a normal bullet?
Modern tanks shell use saboted amunition, guidance fins and other technology that make spinning the projectile irrelevant and even less precise. A lot of the other answers touch on some possible reasons for this. In general, to sum them up, modern tank ammo doesn’t work like bullets do.
What happens if you shoot a round through a tank armor?
May not sound like a lot, compared to using an explosive round, but the damage caused as it passes through and the heat generated inside the tank is generally catastrophic; whereas modern armor can often withstand explosive rounds. The d.u. on the Abrams’ round actually causes the armor to catch fire as it passes through!
