With a distance between a flying plate and main armour in the range of 1 m, the achieved residual penetration is around 1.5 to 2 caliber, independent of the NATO‐angle of 30°, 45° or 60° of the flying plate to the shaped charge axis. This is a surprising result because at near distances a number of explosive reactive armour sandwiches with relatively small high explosive layers have typically strong angle effects in their protection.
