Abstract: A watercraft includes a support structure and a protected space, object or the like within an outer shell of the support structure. To protect the space, object, or the like, for example, a sensitive subassembly in the watercraft, against threats posed by shaped charges, a protective device is positioned between the outer shell and the sensitive subassembly. The protective device includes a multitude of reactive protective elements arranged in a flexible support construction oriented at an angle to the direction of threat. And the support construction is connected, such as, with positive locking and/or friction locking and/or with substance-to-substance bond, to the support structure of the watercraft.

Abstract: The invention describes a rigid or flexible pyrotechnic protection surface which is free or integrated into a housing, for medium-heavily and lightly armored vehicles, protection arrangements and surfaces to be protected, corresponding to FIG. 1, with a single-layer or multi-layer carrier (4) of any configuration which is inclined in the region of action of the threat and pyrotechnic layers (2, 3) mounted on the carrier on both sides. Shock waves and reaction gases are formed by the firing of both layers and are accelerated both in opposite relationship to and also in the direction of the penetrating hollow charge threat (1). In that way both the front powerful blast elements and also a great blast length are disrupted and thus lose their penetration capability or are at least greatly diminished in respect of their residual power. The pyrotechnic protection surface is disposed in a condition of dynamic equilibrium over the entire period of action.

Abstract: A highly effective and also inert active penetrator, an active projectile, an active airborne body or an active multipurpose projectile with a constructively adjustable or settable relationship between penetrating power and lateral effect. The end ballistic total effect which is obtained from the penetrating depth and covering the surface or stressing of the surface is initiated in an active case by means of a releasable arrangement or installation which is independent of the position of the active body.
