Abstract : A fuze includes a conically shaped body having a central longitudinal channel communicating with a rearward central chamber, a firing pin assembly containing a primary and a biased secondary firing pin disposed in the chamber, a delay arming assembly disposed in the chamber, a sleeve-containing a setback locking assembly disposed in chamber, and a pyrotechnic smoke cartridge located in the hollow of the sleeve. The arming assembly contains two V-shaped pivotable levers held in the safe position by the secondary firing pin extending into a hole in each lever and by a detent pin extending into a hole in the lower lever, each lever having hole containing a firing ball. On firing the projectile from the gun, the biased detent pin is withdrawn by setback force and the detents on the secondary firing pin are withdrawn by centrifugal force and align the firing pin are withdrawn by centrifugal force and align the firing balls with the firing pins and the cartridge primer. On ground impact the crush cap collapses, driving the primary firing pin into the secondary firing pin, which impacts the firing balls striking the primer. Keywords: fuzes; Artillery; ammunition.
