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 next generation ammunition, called 120 mm APFSDS-T M829A2, entered service in 1994 and is the armor-piercing ammunition currently being produced by General Dynamics Ordnance and Tactical Systems for the 120 mm M256 gun of M1A1 and M1A2 tanks. It is a technology improvement over the M829A1.
APDS-rounds were commonly used in large caliber tank guns up until the early 1980s, but have since been superseded by armor-piercing fin-stabilized discarding sabot (APFSDS) projectiles, which use fin-stabilization and can be fired from smoothbore guns. [2]

The KE-W round is known for its exceptional armor-penetrating capabilities, utilizing kinetic energy to defeat armored targets. It is commonly used by modern main battle tanks as their primary anti-tank ammunition. The round is mainly used on the NATO 120x570mm cannons. The main users are the American Abrams tank, and the German Leopard [3] tank.
Seminal research on two important sabot configurations for long rod penetrators used in APFSDS ammunition, namely the "saddle-back" and "double-ramp" sabot was performed by the US Army Ballistics Research Laboratory during the development and improvement of modern 105mm and 120mm kinetic energy APFSDS penetrators and published in 1978, [1 ...
For example, a long line of armour-piercing discarding sabot (APDS) rounds was developed by Rheinmetall. Originally, the Leopard 2 was outfitted with the DM23 kinetic energy penetrator, [ 56 ] based on the Israeli 105 mm M111 Hetz which itself was a licensed copy of the American M735 round. [ 57 ]
the new round uses a new sabot design, and a Tungsten Alloy penetrator of increased length compared to prior generation Russian APFSDS ammunition. Used on 2A46M-4/5 with new autoloader. Cartridge dimension: 735 mm [3] Penetrator dimension: 640 mm 28-29: 1 L/D; Round weight: ? kg; Projectile weight (including sabot): 8.4kg; Penetrator weight:
