Flammability promoting ammunition for use against airborne targets

A round of ammunition, particularly for use against airborne targets, such as aircraft and similar targets, said round of ammunition comprising a casing capable of fragmenting into splinters, explosive material in the form of at least one explosive charge located within and capable of fragmenting said casing, oxygen for reaction with fuel or other combustible materials in the target, and material for supporting the flammability of combustible material located on or in the target, wherein the improvement comprises that said casing has a shaped head portion and an axially extending cylindrically shaped portion extending axially rearwardly from said head portion, a core of explosive material located within and extending in the axial direction of the cylindrically shaped portion of said casing, an inner ring-shaped body of oxygen releasing material laterally disposed about said core, an outer ring-shaped body of explosive material laterally enclosing said inner ring-shaped body, first means for igniting said outer ring-shaped body and second means within said casing for providing a delayed ignition of at least said core of explosive material relative to the ignition of said outer ring-shaped body.
