The simulation presents the Leopard 2K's DM13 APFSDS projectile impacting the turret of the T-64A (1971). The T-64A (1971) featured a new turret with High Hardness Armour (HHA) inserts and a Rolled Homogenous Armour (RHA) backing plate.

The Leopard 2K was a prototype MBT designed and tested in the early 1970's. Some were fitted with the new Rh-120 cannon, with one of the first projectiles being the DM13 Armour Piercing Fin Stabilised Discarding Sabot (APFSDS) projectile. DM13 was a jacketed projectile, featuring 2 tungsten alloy cores inside a steel jacket. The impact velocity at 250m has been approximated based on a muzzle velocity of 1650m/s. At ~40° 250m, it has a predicted penetration of ~390mm RHA LoS.

At the impact point, the turret armour has a cut out for the main optic, reducing its thickness. Despite this, the Line of Sight (LoS) thickness is 250mm Cast Homogenous Armour (CHA), 150mm HHA, and 30mm RHA (430mm of steel total). This turret design was to reduce the thickness of the T-64 aluminium filled turret, while still providing exceptional protection. According to some sources, the HHA was quite brittle and there were problems with welds splitting. These factors seem to be detrimental to the turret, as 430mm of steel thickness provided less than 390mm of protection, giving a mass effectiveness of ~0.9.

The turret design seems particularly complex to produce and assemble, with it being unlikely to provide much benefit over a fully cast turret with equal CHA thickness.
