With kinetic energy penetrator rounds, solid shot and armour-piercing shell gave way to armour-piercing discarding sabot ( APDS ) ( a product of 1944 ), and fin-stabilized ( APFSDS ) rounds with tungsten or depleted uranium penetrators.

However, the force of a modern depleted uranium armour piercing fin discarding sabot round at the muzzle can exceed 6000 kN ( a rough estimate, considering a uranium 60 cm / 2 cm rod, 19g / cm 3, @ 1, 750 m / s ).

These include the following : " Stun " ( that disorients with a blinding flash of light along with a deafening popping sound ) : " Armor Piercing Discarding Sabot " ( releases a solid sharpened rod of depleted uranium ); " HEAP " ( High Explosive Armor Piercing );

An important development was the Armour-piercing discarding sabot, or APDS . An early version was developed by engineers working for the French Edgar Brandt company, and was fielded in two calibers ( 75 mm / 57 mm for the Mle1897 / 33 75 mm anti-tank cannon, 37 mm / 25 mm for several 37 mm gun types ) just before the French-German armistice of 1940.

Some Russian sources claim the hard-kill APS is effective even against depleted uranium-cored armor-piercing fin-stabilized discarding sabot ( APFSDS ) rounds traveling at, but others are skeptical, saying the fragmentation charge would not do much to the dense penetrator; while it might be able to push it off course somewhat with a hit-to-kill approach, it likely won't do much to stop it.
