Abstract:
1. A fixed munition for use in a barrel of a low-pressure launching unit, the fixed munition comprising: a cylindrical body having a centrally located bore, a charge end and a discharge end; said bore having a reduced diameter on said charge end thereby defining a ledge portion within said bore, wherein a length of said bore extending from the ledge portion to the discharge end or approximately to the discharge end has a substantially constant diameter; a primer charge positioned in said reduced diameter of said body on said charge end; said bore being filled above said primer charge with a propellant and being filled above said propellant with a payload; and means for uniquely identifying said payload contained in said body; wherein said body having a construction configured to withstand high pressure developed within said bore thereof that exceeds an allowable working pressure of the barrel of the low-pressure launching unit and is configured such that said high pressure developed within said bore thereof that exceeds the allowable working pressure of the barrel of the low-pressure launching unit is not exposed to an inner bore of the barrel of the low-pressure launching unit whereby said body of the fixed munition withstands said high pressure thereby acting as the barrel of the low-pressure launching unit, wherein the allowable working pressure does not exceed approximately 3000 pounds per square inch, and wherein said high pressure that exceeds the allowable working pressure of the barrel of the low-pressure launching unit is between approximately 12,000 pounds per square inch and approximately 15,000 pounds per square inch.
