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 90 mm gun M1/M2/M3 was an American heavy anti-aircraft and anti-tank gun, playing a role similar to the German 8.8cm Flak 18. It had a 3.5 in (90 mm) diameter bore, and a 50 caliber barrel, giving it a length of 15 ft (4.6 m).

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.

Jan 13, 2024 · In 1984, Engesa initiated the development of an APFSDS (Armor Piercing Fin Stabilized Discarding Sabot) round for the low pressure 90 mm gun of the EE-9. Why exactly Engesa entered such an endeavor is unknown, as kinetic energy projectiles are usually not viable for low pressure guns.

Jan 2, 2018 · The US instead opted for a newly developed 90mm gun, the T119. This gun was a vast improvement over the M3A1. Firing it’s APDS (Armor-Piercing Discarding-Sabot) round, it could punch through 11.1 inches (282mm) of homogenous steel armor, angled at 30 degrees, at a distance of 1000 yards (914.4 meters).

As tank armor improved, the primary anti-tank main gun round for most Western tanks shifted toward KE (kinetic energy) projectiles, specifically APFSDS (armour-piercing fin-stabilized discarding sabot), effectively long dense "darts".

Jan 9, 2004 · US 90 mm APCR, according to copies of US army documents in my possession, was issued in March 1945 and was very rare. Some (secondary) sources state that it was available from about January...

Dec 5, 2002 · 90mm "APDS" (I think that is actually HVAP) Probability of a first round hit (not kill) of a tank gun firing at a tank-sized, standing target. Important,percent values are for first hit,not average (which values are more accurate).A skilled and experienced gunner could reach better and worse of course.

Nov 1, 2011 · Unfortunately, the Germans weren't armed with hillsides. The 90mm's performance was comparable to the Flak 36 88mm, not the later longer 88s. Or about 80% of the 17 Pdr firing equivalent APCBC shot (not APDS).

Jan 30, 2016 · APDS, was the ability to get though the forward glacies of tanks like the Panther at use-able ranges. The hull of the tank is a good bit bigger than the turret, so is an inability to be accurate enough to hit the turret a problem?
