Public safety agencies in many large metropolitan cities need a mobile system which is capable of safely transporting ‘terrorist-type’ bombs from a discovery point to a disposal area. In view of the immediate requirement of such a system by the Government of the District of Columbia, Metropolitan Police Department (DC-MPD), the Naval Research Laboratory has provided an interim solution to this problem by designing and fabricating a prototype explosives containment system. The crucial elements of the system which led to the successful demonstration are an ultrahigh-strength, highly fracture resistant steel pressure vessel held in a specially fabricated support base also made of high-strength, fracture tough steel. Materials for the system were selected and evaluated on the basis of the most advanced metals characterization procedures to ensure fracture-safe performance in this unique application.
