Shock mitigation assembly for a penetrating weapon

A shock mitigation assembly for an explosive weapon having an explosive charge, comprising:

• an electronic device having an electronic circuit that is connectable to an electro-explosive device to control detonation of the explosive charge;
• a weight attached to the electronic device to mitigate high frequency shock forces and to form an electronic subassembly that includes the electronic device and the weight;
• a housing enclosing the electronic subassembly, including the weight, within an enclosed volume;
• a hyperelastic material between the housing and the electronic subassembly, where the hyperelastic material has a modulus of elasticity that maintains elastic characteristics in response to shock, temperature, or a combination of shock and temperature;
• and
• a shock mitigation plate between the electronic subassembly and the cover;
• where the housing includes a casing and a cover secured to the casing, the casing and the cover cooperating to define the enclosed volume, and the casing and the cover include corresponding features that mate with one another and prevent separation of the cover from the casing, and a hyperelastic material fills a gap between the cover and the casing.
