Abstract: A method for ocean surface delivery of ordnance and clearing of explosive mines and obstacles from a navigable sea channel includes the step of providing quantities of ordnance adapted to survive impact and prolonged immersion in sea water and to arm in response to release from a mobile ocean surface vehicle and to pressure actuation upon submersion to a desired depth in sea water and then to detonate in response to receiving a preselected signal transmitted to the ordnance from a standoff location. The method also includes the step of delivering the quantities of ordnance from a mobile ocean surface vehicle toward multiple sites in a navigable sea channel containing obstacles and explosive mines therein so as to cause arming of the ordnance followed by impact thereof with the navigable sea channel and submersion and emplacement thereof at the multiple sites in the navigable sea channel.

Abstract: A hand emplaced underwater mine penetration system includes a launching ambly and a munition assembly. The launching assembly includes a firing device which receives a magnetic or acoustic signal from a standoff signal generator, and a launch tube having a forward open end, an opposite rear end connected to the firing device and a bore extending between the ends. The munition assembly is adapted for insertion within and firing from the bore of the launch tube of the launching assembly and includes a cartridge having explosive elements therein and a fuze disposed at a forward end of the cartridge and adapted to detonate and explode the explosive elements in the cartridge upon impact with an underwater mine.

Abstract: A method for air delivery of ordnance and clearing of explosive mines and stacles from a navigable sea channel includes the step of providing quantities of ordnance adapted to survive impact with land and sea and prolonged immersion in sea water and to arm in response to air flow pressure and then detonate in response to receiving a preselected signal transmitted to the ordnance from a standoff location. The method also includes the step of delivering the quantities of ordnance through the air toward multiple sites in a navigable sea channel having obstacles and explosive mines therein so as to cause arming of the quantities of ordnance followed by impact thereof with the navigable sea channel and submersion and emplacement thereof at the multiple sites in the navigable sea channel.

Abstract: Improved shaped charge assembly of relative lightweight and sealable consction and composed of nonmetallic and nonmagnetic materials that can be used for selectively destroying or disarming a variety of targets. The assembly is generally made up of casing means of tubular-like configuration, jet-forming linear means of conical shape and shaped charge body means. The liner means is interposed between the ends of the casing means where the charge body means is interposed between the casing means and the liner means at one end of the casing means. Depending upon the manner in which the assembly is to be used, at least the one end of the casing means is capped. Suitable plastic materials for use in the liner means have been found to be either polyethylene or polypropylene, having an ultra-high molecular weight.
