ABSTRACT:
An ignition arrangement for a barrel assembly (10) including a barrel (11) having a plurality of projectiles (15a, 15b, 15c) axially stacked within the barrel (11) together with respective propellant charges (20) for propelling the projectiles sequentially from the barrel, said ignition arrangement including a fuse (21, 22) disposed in a cavity (27) provided in a body (18) of each projectile, wherein the cavity (27) communicates both forwardly (28) and rearwardly (29) of the projectile body (18); whereby in use, said fuse (21) burns at a controlled rate in the cavity (27) and causes ignition of the propellant charge (20) associated with said projectile (15a), which in turn ignites the next following fuse (22) associated with a trailing projectile (15b).
