How do APFSDS rounds work?

Sabot design APFSDS rounds generally operate in the range of 1,400 to 1,800 m/s (4,593 to 5,906 ft/s). The sabot, necessary to fill the bore of the cannon when firing a long, slender flight projectile, is parasitic weight that subtracts from the potential muzzle velocity of the entire projectile.

Can ERA defeat APFSDS?

Kontakt-5 is a type of second-generation explosive reactive armour (ERA) originating in the Soviet Union. It is the first type of ERA that is effectively able to defeat modern armour-piercing fin-stabilized discarding sabot (APFSDS) rounds.

When were APFSDS invented?

In mid-1944, the resulting APDS (the ‘D’ standing for “discarding”) projectile type was introduced into service for the UK’s QF 6 pounder anti-tank gun and later in September 1944 for the QF 17 pounder anti-tank gun.

How thick can APFSDS penetrate?

It was able to penetrate only at ranges of 1500m or less, far less than the maximum engagement range of modern tank battles as demonstrated in the Gulf War where tanks were hitting each other from 3200m away.

How does high explosive anti tank work?

High-explosive anti-tank (HEAT) is a type of shaped charge explosive that uses the Munroe effect to penetrate heavy armour. The jet’s effect is purely kinetic in nature; the round has no explosive or incendiary effect on the target.

How does explosive reactive Armour work?

Explosive reactive armour On attack by a penetrating weapon, the explosive detonates, forcibly driving the metal plates apart to damage the penetrator. Against a shaped charge, the projected plates disrupt the metallic jet penetrator, effectively providing a greater path-length of material to be penetrated.

Who invented explosive reactive armor?

It was only until the 1970s that the first successful Explosive Reactive Armor was created and patented by the German researcher Dr. Manfred Held.

Does APFSDS bounce?

APFSDS don’t bounce off because they are built in such a way that they deliver that energy even at extreme angles. It’ll shatter before it’ll ever bounce off the armor.

What is APFSDS and how does it work?

APFSDS, also known as Armour Piercing Fin Stabilized Discarding Sabot, is a type of tank round that uses sheer kinetic energy focused on an extremely narrow point to punch it’s way through enemy armour. The shot separating from its shell. You can see that it’s extremely narrow and utilizes an extremely sharp and pointed edge, a bit like a dart.

How does APFSDS defeat reactive armor?

APFSDS defeats reactive armor by flying faster and using more kinetic energy than the reactive armor can safely deflect from the armored vehicle. The high velocity helps the nose of the round penetrate through the reactive armor, sometimes before the charge can fully detonate.

Can APFSDS be fired from a low twist barrel?

Even smooth-bore fired APFSDS projectiles incorporate fins that are slightly canted to provide some spin rate during flight; and very low twist rifled barrels have also been developed for the express purpose of firing APFSDS ammunition.

How is the high velocity and energy of APFSDS achieved?

The high velocity and energy of APFSDS are achieved by using a much larger-diameter cannon than the dart itself, allowing more energy to be imparted into the round than could be achieved if the cannon were the same diameter as the dart.
