1. A test and/or practice ammunition comprising:
a cartridge shell with
a drive received therein, and
a communication interface attached to or accommodated in a shell base of the cartridge shell; and
at least one projectile coupled to the cartridge shell, the at least one projectile with a projectile head or a projectile ogive, wherein:
a programmable fuze is arranged in the projectile head or in the projectile ogive, said programmable fuze comprising a fuze amplifier and an electronic fuze controller in communication with the communication interface;
the projectile further includes
a periphery defining a cavity;
a pyrotechnic configured to generate a visible signal,
a separating charge, and
an inert material for damming;
the inert material is positioned within the cavity and surrounds the separating charge; and
the electronic fuze controller is configured to receive data specific to a programmed air blast point or at/in a programmed target from the communication interface such that a data transmission between the communication interface and the electronic fuze controller is within the cartridge shell, and trigger the programmable fuze, such that the projectile separates into two or more parts, and the pyrotechnic and the separating charge are ignited, once the projectile has reached the programmed air blast point or at/in the programmed target.
