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 M829A4 is a fifth-generation APFSDS-T cartridge using a depleted-uranium penetrator with a three-petal composite sabot; the penetrator includes a low-drag fin with a tracer and a windshield and tip assembly. [11] Its propellant maintains consistent muzzle velocities across operational temperatures from −25 to 145 °F (−32 to 63 °C).
A sabot (UK: / s æ ˈ b oʊ, ˈ s æ b oʊ /, US: / ˈ s eɪ b oʊ /) 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.
Armour piercing discarding sabot munitions were developed to increase penetrating performance of anti-tank projectiles by generating higher impact velocity.A larger projectile would require a completely new weapon system, but increasing velocity faced the limitation that steel armour-piercing (AP) projectiles shattered at velocities above about 850 m/s when uncapped.
A BM-42 APFSDS projectile. Entered service in 1986. The projectile is double tungsten alloy rod sheathed in low melting point alloy covered with steel, intended to increase penetration against non-explosive reactive armour (NERA) such as Chobham armour. Is slowly being replaced by newer models such as 3BM59/60. Country of origin: Soviet Union
The KE-W APFSDS round is widely used by various military forces around the world. It is a crucial component of a tank's ammunition loadout, providing the capability to engage and destroy enemy armored vehicles at extended ranges. It is also used by the M1 Abrams Main battle tank. [1]
Rheinmetall is developing a new generation APFSDS round featuring a semi-combustible cartridge case, new propellant, and new advanced long rod tungsten penetrator, and a high-explosive air-bursting munition (HE ABM) based on the 120 mm DM11 HE ABM in parallel with the gun.
ACORD also provided expertise on digital data standards for a collaboration with IBM, ISN, and Marsh to streamline the proof of insurance process with the help of blockchain technology. The partnership is an attempt to eliminate the time- and labor-intensive paper insurance certificates that dominate the global insurance market. [9]
