Overview
editThe 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.
Design and components
editThe round consists of a sub-calibre penetrator made of tungsten, enclosed in a discarding sabot. The sabot provides stability during the initial stages of flight and is discarded upon exiting the barrel, allowing the penetrator to continue towards the target with high velocity.
| Round | Year Introduced | Description |
|---|---|---|
| KE-W Terminator | 1996 | |
| KE-W A1 | 1999-2000 | DM43 |
| KE-W A2 | 2003 | based on the M829A2.[4] |
| KE-W A3 | A2 with more powerful propellant | |
| KE-W A4 | 2022 | DM63 |
Performance
editDue to its high muzzle velocity[1] and dense tungsten penetrator, the KE-W APFSDS round can penetrate thick armor, making it effective against heavily armored vehicles. The kinetic energy transfer upon impact contributes to its effectiveness in defeating armored targets.
Usage
editThe 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]
