Armour piercing discarding sabot munitions were developed to increase penetrating performance of anti-tank projectiles by generating higher impact velocity.A larger projectile would require a completely new weapon system, but increasing velocity faced the limitation that steel armour-piercing (AP) projectiles shattered at velocities above about 850 m/s when uncapped.
The IWS is chambered in a 15.2×169 mm armor-piercing fin-stabilized discarding-sabot cartridge, and is the first man-portable rifle to use this type of ammunition. The first variant of the weapon was the proposed AMR 5075 (AMR standing for anti-materiel rifle). It was to fire the same type of ammunition as the IWS 2000 and to use a 5-round ...
Armour-piercing fin-stabilized discarding sabot (APFSDS), long dart penetrator, or simply dart ammunition is a type of kinetic energy penetrator ammunition used to attack modern vehicle armour. As an armament for main battle tanks , it succeeds armour-piercing discarding sabot (APDS) ammunition, which is still used in small or medium caliber ...
The M829 is an American armor-piercing fin-stabilized discarding sabot kinetic energy penetrator tank round.Modeling was done at the Ballistic Research Laboratory at Aberdeen Proving Ground, [1] which was incorporated into the Army Research Laboratory in 1992.
A sabot (UK: / s æ ˈ b oʊ, ˈ s æ b oʊ /, US: / ˈ s eɪ b oʊ /) is a supportive device used in firearm/artillery ammunitions to fit/patch around a projectile, such as a bullet/slug or a flechette-like projectile (such as a kinetic energy penetrator), and keep it aligned in the center of the barrel when fired.
Armour-piercing fin-stabilized discarding sabot (APFSDS) using a sabot and tracer (APFSDS-T). Typically used against other modern tanks. There are different ways to measure penetration value. NATO uses the 50% criteria against 260BHN Steel, while the Soviet/Russia standard is higher (80% had to go through). [citation needed]
The XM1203 Armor Piercing Fin Stabilized Discarding Sabot with Trace. The projectile itself is 50 mm in diameter, encasing a long thin dart, designed to pierce armored vehicles. A light "sabot" grips the barrel's rifling, in order for the shell to get the full power of the expanding gas.
When supplied, Armour-piercing discarding sabot (APDS) ammunition could penetrate 209 mm (8 inches) of armour at 500 m and 192 mm (7.6 in) at 1,000 m at a 30-degree angle, though the accuracy of the APDS round was poor during the war. In comparison, the M7 gun on the standard M10 using APCBC ammunition would penetrate 98 mm (3.9 in) of armour ...
