What is the range of a sabot round?

Sabot design APFSDS rounds generally operate in the range of 1,400 to 1,800 m/s (4,593 to 5,906 ft/s).

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.

How far is Apfsds?

Modern APFSDS can reach muzzle velocities of up to 1700 m/s and burn through 2000 mm of RHA. These rounds can be “ballistically flat” for 1600m which is how far they can go before gravity has a significant effect on their trajectory.

Is depleted uranium stronger than tungsten?

A byproduct of nuclear reactor fuel, depleted uranium was harder and denser than existing tungsten-tipped penetrators. Accelerated to extremely high speeds, this allowed a depleted-uranium (DU) round to smash through an unprecedented amount of armor.

How much can Apfsds penetrate?

So instead of having some mind-boggling penetration (for an APFSDS fired with the short L/44 barrel) against all types of armor, the penetration against RHS/composite armor might be as low as ~660 to 700 mm; enough to defeat the main armor of tanks like the T-80U, T-90 and Type 99.

What is the muzzle velocity of an APFSDS round?

Typical velocities of APFSDS rounds vary between manufacturers and muzzle length/types. As a typical example, the American General Dynamics KEW-A1 has a muzzle velocity of 1,740 m/s (5,700 ft/s). This compares to 914 m/s (3,000 ft/s) for a typical rifle (small arms) round. APFSDS rounds generally operate in the range of 1,400 to 1,900 m/s.

What does APFSDS-T mean?

The Armor Piercing, Fin Stabilized, Discarding Sabot – Tracer (APFSDS-T) cartridge is a type of kinetic energy (KE) armor defeating round. It consists of a fin stabilized subprojectile, a tracer assembly attached to the rear of the fin and a depleted uranium (DU) or tungsten penetrator with a ballistic tip to reduce drag.

What is the steady spin rate of an inflight APFSDS projectile?

Classically, using a 120 mm smooth bore gun, the value of the nondimensional steady spin rate of the inflight APFSDS projectile is about 0.01. In our case, a medium caliber APFSDS projectile is fired using a rifled barrel gun.

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.
