How fast is an APFSDS round?
1,400 to 1,800 m/s
As a typical example, the American General Dynamics KEW-A1 has a muzzle velocity of 1,740 m/s (5,700 ft/s). This compares to 914 m/s (3,000 ft/s) for a typical rifle (small arms) round. APFSDS rounds generally operate in the range of 1,400 to 1,800 m/s (4,593 to 5,906 ft/s).
What does sabot round stand for?
A sabot (UK: /sæˈboʊ, ˈsæboʊ/, US: /ˈseɪboʊ/) 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.
When was APDS developed?
June 1944
APDS was introduced in June 1944 for 6 Pounder 57mm guns and had a significantly higher penetration performance over any previous types of AP ammunition, in fact its performance was about twice as good/deep (140mm compared to 84mm at 500 yards) although it lost accuracy over long ranges (1000 yards plus) because of …
How do APDS rounds work?
Armour-piercing discarding sabot (APDS) is a type of spin-stabilized kinetic energy projectile for anti-armour warfare. It consists of a sub-caliber round outfitted with a sabot to increase velocity compared to a full caliber round by firing a smaller lighter projectile from a relatively larger propellant-charge.
How thick can Apfsds penetrate?
So instead of having some mind-boggling penetration (for an APFSDS fired with the short L/44 barrel) against all types of armor, the penetration against RHS/composite armor might be as low as ~660 to 700 mm; enough to defeat the main armor of tanks like the T-80U, T-90 and Type 99.
What is a depleted uranium bullet?
Depleted uranium is the byproduct of the enriched uranium needed to power nuclear reactors. Depleted uranium is roughly 0.7 times as radioactive as natural uranium, and its high density makes it ideal for armor-piecing rounds such as the PGU-14 and certain tank shells.
Who made Apds?
Between 1941–1944, Permutter and Coppock, two designers with the UK Armaments Research Department (ARD), developed a sabot that was discarded immediately after leaving the barrel, so the smaller, heavier, sub-projectile could carry on at the much higher velocity, suffering less drag due to its smaller diameter.
What does APDS stand for?
Authentication Protocol Domain Support Specification. APDS. Avaya Professional Design Specialist (certification) APDS. Armor-Piercing Discarding Sabot. APDS.
Why do APDS rounds have a high velocity?
The higher velocity gives the round increased penetration against armour. To not break at high speed impacts, APDS rounds traditionally features a hardened core made by tungsten or other hard material.
Are APDS rounds still used in modern weapons?
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,…
What is the difference between APCR and APDS rounds?
APCR is found throughout most tech trees, most commonly available to vehicles from mid-WW2 through to early cold war vehicles. APCR rounds are best used against minimally angled armour, where other rounds will be unable to penetrate. APDS rounds utilise a hard core as a sub-calibre penetrator, with a full calibre sabot.
