Buoyant armor for jacketed rounds includes an outer, laminate reinforced strike face having a hardness greater than 640 Brinell. The strike face is configured to strip the jacket off a projectile as it passes through the strike face and to rotate the projectile. An inner, laminate reinforced strike face is separated from the outer, laminate reinforced strike face by a spacer layer. Foam greater than 40 mm thick is disposed behind the inner strike face and is configured to disperse a round and/or its fragments and to provide buoyancy to the armor.
