Structures based upon periodic cellular materials that provide a potential for defeating combinations of both air blast loading and ballistic attack either sequentially or simultaneously, or combination of both. The cellular structures may also be configured to meet the stiffness and strength support requirements of particular vehicle or other applications, systems or structures. The armor is therefore potentially able to support normal service loads and defeat blast and ballistic threats when necessary. The structure provides for using efficient load support capabilities of the material (without a high armor protection level) in low threat conditions, as well as the ability to modify the system to increase its level protection to a desired or required level. This would reduce the weight of the protection system in normal (low threat) conditions which reduces vehicle wear and tear, as well as cost savings in fabrication of applicable structures or systems.

As typically embodied, the present invention's add-on device includes two wedge-shaped structural components that are oppositely congruent and symmetrically connected. In profile, the device describes a pair of nearly triangular quadrilateral figures that are enantiomorphs (mirror images) with respect to the linear bisector (mirror line) at which they join. The device's V-angular upper surface defines the same V-angularity (“deadrise”) as does a V-angular hull bottom, the device thus fitting beneath the hull bottom. The device's V-angular lower surface defines a different angularity, which is imparted to the hull bottom when the device is attached thereto. According to typical inventive practice, the device alters the hull bottom's V-angularity by at least 1° and, at least, covers approximately 100% of the hull bottom's widthwise expanse along approximately 50% or more of the hull bottom's lengthwise expanse. The device modifies a marine vessel's hydrodynamics and/or hydrostatics, and may provide armor and/or wear benefits.
