<p>An ignition device for a projectile (1) having two charges in tandem relationship, i.e. a pre-penetrator (3) and a main charge (4) for action against a target (11) which is protected by a so-called reactive armour (12-17). A piezo-crystal (8) is arranged to sense a first shockwave in the projectile as a result of an impact in the target, and to sense a second shockwave as a result of any collision between the projectile and a plate or the like expelled from the reactive armour. A delay circuit (9) is provided to delay the detonation of the main charge (4), and an inhibition circuit (10) is provided to automatically inhibit said delay if said collision will occur. <IMAGE></p> |
