Description
Base Detonating Fuzes M68 series are delay-action fuzes used with 90mm gun, APC-T cartridges.
Fuzes are of the simple inertia type, without bore-safe provision. The body of the fuze is threaded externally to fit the projectile base cavity, and is threaded internally to receive a booster holder assembly containing a tetryl booster charge and a detonator. The booster holder assembly, in turn, is threaded internally to receive a primer holder assembly containing a primer and black powder delay pellet. The firing pin is contained within the fuze body and is restrained prior to impact by a soft steel washer. The base of the fuze is threaded internally to receive a tracer assembly. The tracer assembly is contained in the base of the fuze.
Fuze M68A1 is slightly larger but lighter than Fuze M68; otherwise the fuzes are identical in design. Fuze M68 contains primer No. 26. Fuze M68A1 contains primer No. 31. M68 tracer is press fit. M68A1 tracer is threaded.
