Reactive armour effective against normal and skew attack

An ad-on reactive armour element effective against normal and skew attack. The element is a multilayer composite body in which each layer tightly bears against each contiguous layer, which multilayer composite body comprises an outer cover (1), at least one explosive layer (2), at least one intermediary inert body (3) and a base plate (4), the intermediary layer or layers may be, for example, of aluminium, glass or ceramics. The armour uses the effect of the dynamic collapse of the inert body (13): the explosion of the explosive layer (2) creates compressive stress within the inert body (3). That pressure closes the crater produced by the first part of the jet so that a new barrier is created for the following part of the jet.
