Description
These fuzes are oblique impact sensitive, point detonating, super-quick types.
The striker pin body assembly consists of an aluminum body with a press fitted steel striker pin. The lower portion of the body is secured to the firing pin body by a circumferential crimp. Upon impact, crush-up initiates the primer and subsequent explosive train.
The firing pin body assembly consists of a firing pin body, plastic hammer, firing pin sleeve, anti-setback washer, firing pin nut, and firing pin. The threads on the lower portion of the body assembly are used for assembling the fuze to the warhead.
The safety-and-arming device consists of a rotor-housing assembly and unbalanced rotor assembly, an escapement assembly and setback weight. The unbalanced rotor assembly houses the primer and detonator and is maintained in the unarmed (out-of-line) position.
The booster assembly consists of a booster housing, lead-in cup and appropriate explosive charges. The threads on the booster housing enable the booster assembly to be threaded into the lower portion of the firing pin body.
Externally the M427 fuze is identical to the M423 fuze. The M427 differs from the M423 in that its internal construction is designed to produce the longer arming time and arming distance required for launch from high-speed aircraft.
