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.
Refer to the two armor-piercing fin-stabilized discarding sabot pictures to see the substantial material nature of a sabot to fill the bore diameter around the sub-caliber arrow-type flight projectile, compared to the very small gap sealed by a driving band or obturator to mitigate what is known classically as windage.
Armor-piercing discarding sabot (APDS) is a type of spin-stabilized kinetic energy projectile for anti-armor warfare. Each projectile consists of a sub-caliber round fitted with a sabot . The combination of a lighter sub-caliber projectile with a full-caliber propellant charge allows for an increase in muzzle velocity compared to full-caliber ...
Armour-piercing fin-stabilized discarding sabot (APFSDS) in English nomenclature, alternatively called "arrow projectile" or "dart projectile" (German: Pfeil-Geschoss, Swedish: pilprojektil, Norwegian: pilprosjektil), is a saboted sub-calibre high-sectional density projectile, typically known as a long rod penetrator (LRP), which has been ...
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.
High-velocity armor-piercing (HVAP) rounds were primarily used by tank destroyers in the US Army and were relatively uncommon as the tungsten core was expensive and prioritized for other applications. Between 1941 and 1943, the British combined the two techniques in the armour-piercing discarding sabot (APDS) round. The sabot replaced the outer ...
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 ...
