for 57mm Anti-Aircraft Ammunition
MGZ-57 is a mechanical, nose, point-detonating fuze with delayed action. The fuze features distance arming and self-destruciton.
Fuze MGZ-57 completes 57 mm HET round for 57 mm automatic anti-aircraft gun S-60.
The fuze is safe in storage, handling and operation and ensures the safe and reliable function of the ammunition in all weather conditions.
Before firing the Safety and Arm device prevents the detonator from positioning into the fire train. Even in case of unintentional ignition of the primer, no transfer of the firing pulse to the fire train can occur.
The fuze is distant armed at distance not less than 20 m from muzzle. At firing the set-back and rotational forces arm the fuze, fixing the elements of the fire train in one line.
Upon impact the fuze provides delayed action within 0.002 to 0.004 s.
In case of no impact the round is self-destruct within 13 to 17 s.
