Armour-piercing discarding sabot (APDS) is a type of kinetic energy projectile fired from a rifled-barrel gun to attack armoured targets. APDS rounds are sabot rounds, firing a spin-stabilized armor penetrating sub-projectile, and were commonly used in large calibre tank guns, up until the early 1980s, but have now been superseded by armour-piercing fin-stabilized discarding sabot (APFSDS) projectiles used in smooth-bore guns, firing a fin-stabilized armor penetrating sub-projectile. However, APDS rounds are still commonly used in small or medium calibre weapon systems. For a given calibre, this type of ammunition can effectively double the armour penetration of a gun, compared to those firing armour-piercing (AP), armour-piercing, capped (APC), or armour-piercing, capped, ballistic capped (APCBC) projectiles. The saboted light armour penetrator (SLAP) concept applies this technology to small arms calibres.
