Abstract: A reactive armour construction comprises a rigidly fixed outer layer and a relatively loosely fixed inner layer mounted on a structure to be protected in such a way that when a projectile penetrates at an oblique angle the outer layer and is incident upon the inner layer, the inner layer is allowed to move laterally relative to the outer layer thereby disrupting the line of attach of the projectile.

Abstract: A composite armour comprises a forward metal armour plate, a metal armour backing plate spaced from and generally parallel to the forward armour plate and between the forward armour plate and the armour backing plate an array of armour layers each inclined at a substantial angle to the plane of the backing plate.

Abstract: A composite armor system comprises a homogeneous metal armor plate and a plurality of reactive armor panels, each said panel comprising a forward layer, an intermediate layer of explosive material and a rearward layer, the homogeneous armor plate being formed with a plurality of recesses in its forward surface and the rearward layer of each reactive armor panel being received in a respective one of said recesses.

Abstract: An explosive package for use in reactive armor comprises an explosive material embedded between layers of a resilient material which are contained between upper and lower rigid plates in a sandwich structure. A construction for the application of reactive armor to a structure to be protected comprises a plurality of such packages, a plurality of projections attached to the said structure and a plurality of holders each attachable to and thereby running between adjacent projections, each of the holders in use holding an edge of one of the said packages, each projection thereby being attached to at least one of the said packages by the holder attached thereto.

Abstract: A composite armour comprises an outer layer of metal, an inner layer of metal, and therebetween an intermediate non-metallic layer, wherein there is provided along an edge of the intermediate layer a deflecting strip of metal, said deflecting strip presenting towards the edge of the intermediate layer a face which is inclined at an oblique angle with respect to the surface of the inner layer.
