Соединенные Штаты Америки M52 Fuze

UPDATE 5-5-2026: A version compatible with M2 mortar rounds was added.

🔎General Information

This is a detailed 3D model for the ** United States M52 Fuze**. This fuze is designed for use with artillery and mortar rounds. It is suitable for 3D printing and animations.

This is the United States M52, a series of High-Explosive (HE), setback-armed, Impact (IMP) fired, Point-Detonating (PD) Mortar-Bomb fuzes. The M52 series of fuzes include the M52, M52A1, M52A1B1, M52A2, M52A2B1, M52B1, M52B2 and M52B10. The safety-wire is removed before firing. On Mortar-Bomb firing, setback drives the setback-pin rearward against its spring. This frees the spring-loaded bore-riding safety-pin, which is forced outward until it strikes the inner wall of the mortar-tube. As the fuze emerges from the mortar-tube, the safety-pin is ejected. This frees the slider which is driven by the slider spring until the detonator is aligned with the Firing-Pin (FP). Impact forces the striker rearward, driving the FP into the detonator to initiate the explosive-train.
