Kontakt-5 ERA (15mm HHA plate, 8 x 4S22 explosive elements)
+
50mm SHA + 35mm Glass Textolite + 50mm SHA + 35mm Glass Textolite + 50mm SHA at 68 degrees


120mm muzzle velocity (M829A2) - 1680 m/s. 1630 m/s refers to a distance of approximately 1 km.

SHA - Semi Hardened Steel (+400 BHN RHA)


The interior of the ERA block was simplified for technical reasons. Inside there are light brackets positioning explosive elements.
