According to an aspect of the invention, there is provided a system for reducing water-entry shock for a projectile entering the water, the system comprising: a first component, the first component being moveable to a target region for which water-entry shock is to be reduced, and arranged to interact with the water, for reducing water-entry shock for a second component; a second component in the form of the projectile, arranged to enter the water in the region for which water-entry shock has been reduced by the first component, functionality of the second projectile component being triggered by the water.

A method of permanently affixing tungsten cube fragments to the fragmentation warhead in a convex Claymore mine having a plastic case and a housing. Pieces of predetermined sized structural film adhesive are positioned at temperature 60 F.5 F., then pressed into the plastic case while pouring tungsten cubes into the case. The cubes are arranged into desired patterns all at temperature 70 F.2 F. An interface plate and 5 lbs of weight are then placed atop thereof and all are heated in an oven at temperature 205 F.5 F. for four hours for full cure of a desired product.
