Amphibious armor

Buoyant armor for jacketed rounds comprising:

• an outer, laminate reinforced strike face having a hardness greater than 640 Brinell and configured to strip the jacket of a projectile as it passes through the strike face and to rotate the projectile;
• an inner, laminate reinforced strike face separated from the outer, laminate reinforced strike face by a spacer layer;
• foam greater than 40 mm thick behind the inner strike face and configured to disperse a round and/or its fragments and to provide buoyancy to the armor;
• and
• the aggregate specific gravity of all said layers combined being less than one g/cm3.

Buoyant armor for jacketed rounds comprising:

• an outer, laminate reinforced strike face having a hardness greater than 640 Brinell and a thickness of between 2-10 mm and configured to strip the jacket off a round as it passes through the strike face and to rotate the round;
• a foam layer behind the outer laminate reinforced strike face configured to prevent a reflected projectile shock wave from damaging the outer, laminate reinforced strike face;
• an inner, laminate reinforced strike face behind said foam layer and configured to fragment the stripped round;
• a thicker low density foam layer sandwiched between two thinner structural foam layers behind the inner, laminate reinforced strike face and together having a thickness greater than 40 mm and configured to disperse the round and/or its fragments and provide buoyancy to the armor;
• and
• the aggregate specific gravity of all said layers combined being less than one g/cm3.
