Deflagration device for underwater unexploded ordnance

An underwater unexploded ordnance (UXO) mitigation device, comprising:

• an inverted snorkel including a curved part and a straight part, wherein said straight part includes a proximal end and a distal end that merges into said curved part, and wherein said curved part terminates at a curved end;
• an upper housing being connected to said inverted snorkel, wherein said upper housing is formed with an opening;
• an initiator being inserted into said opening,
• wherein said upper housing is further formed with a conical void, wherein said conical void merges into said opening, wherein said conical void includes an increasing taper when viewed in cross-section from a minimum width proximate said opening and a maximum width distal said conical void;
• and,
• an energy-focusing guide being attached to said upper housing, wherein said energy-focusing guide formed with a deflatration chamber, which merges into said conical void, wherein said initiation chamber includes a decreasing taper to a maximum chamber width proximate said upper housing to a minimum chamber width distal said upper housing.

A method for deflagration of underwater unexploded ordinance (UXO), comprising:

• providing an energy-focusing guide;
• connecting an upper housing being connected to said energy-focusing guide, wherein said upper housing is formed with an opening and a tapered void, and wherein said opening merges into said tapered void;
• placing an energetic charge in said tapered void;
• inserting an initiator through said opening and into said void so that said initiator is in contact with said void;
• and,
• establishing a transient chamber for said initiator with an inverted snorkel attached to said upper housing.
