Kontakt-5
From Warlike
Q247998
Kontakt-5 is a type of second-generation explosive reactive armour (ERA) originating in the Soviet Union. Due to the shortcomings of Kontakt-1, NII Stali developed a new type of reactive armor, Kontakt-5, so that it also affects the penetration characteristics of APFSDS projectiles, unlike Kontakt-1. In addition, Kontakt-5 is not just additional armor, but is clearly integrated into the vehicle hull. The Kontakt-5 modules have a significantly thicker steel upper side. Depending on the module, they contain one or two 4S22 reactive elements. The explosive of a 4S22 element has the TNT equivalent of 330 g. It is sensitive enough to be activated by impacts from armor-piercing projectiles as well as shaped charge warheads. Kontakt-5 produces a stronger defensive detonation than Kontakt-1 and the thicker steel flyer plate thrown at the APFSDS projectile breaks or bends it. The increase in defensive capability led to the development of more advanced APFSDS projectiles.
