ABSTRACT:
A fuze for the firing of a projectile from a gun barrel comprises a breech piece threaded onto the rear end of the barrel and defining therewith a cylindrical chamber for a charge of liquid propellant to be tangentially introduced upon insertion into the barrel of the projectile to be fired. A pyrotechnical detonator is carried on the aft end of the projectile and extends rearwardly therefrom into the chamber when the projectile is thus emplaced, with the injected propellant circulating around it. The projectile is discharged upon ignition of the detonator by a firing pin. The pin is guided in a plunger surrounded by a retractable sleeve which serves to position the shell in the barrel by engaging an area of its aft end surrounding the detonator.
