This invention makes it possible, for the same volume of ammunition, to have a larger number of shots and to carry out the loading of the ammunition simply and quickly. The cartridge (1), consists of a sole (2) fixed to a case (3), in which are accommodated a plurality of assemblies (11) comprising pyrotechnical ejection charges (6), pyromechanical assemblies (7), ignition charges (8), effective charges (9) and the caps (10). The case (3) is provided with a plurality of receptacles and comprises at its base either a blocking device (4) or a gasket which is seated in a groove (41). The assemblies (11) are independent and are arranged in parallel in the various receptacles of the case (3); the sole (2) is common to the various receptacles of the case (3) and comprises electrical fuses.
An ammunition (20) comprising a rack (21), said rack receiving a plurality of cartridges (1), each cartridge consisting of a case (3), a sole (2) fixed to said case, a plurality of receptacles within said case, a plurality of assemblies (11) accommodated in said receptacles, each of said assemblies comprising a pyrotechnical ejection charge (6), a pyromechanical device (7), an ignition charge (8), an effective charge (9) and a cap, said assemblies being independent and being arranged in parallel in said receptacles, each assembly comprising one electric fuse (5), said electrical fuses being received in said sole (2), said sole (2) being common to said receptacles, each of said cases having a base, a groove (41) located at the base of each of said cases, a gasket (40) seated in each of said grooves, each of said gaskets (40) blocking said cartridges to said rack and ensuring sealing said cartridges to said rack.
