VUBS-1M is a mechanical, nose, point-detonating fuze with delayed action and short-timed self-destruction.
It is designed for drill firing at short ranges (length of 4 km and over).
The fuze completes High Explosive ammunition for artillery and tank guns of the following caliber:
· 85 mm, 100 mm, 122 mm, 130 mm and 152 mm artillery guns
· 100 mm, 115 mm and 125 mm smoothbore tank and antitank guns
The fuze is safe in storage, handling and operation and ensures the safe and reliable function of the ammunition in all weather conditions.
· Completes ammunition for both rifled and smooth-bore guns.
· Ensures round ignition on hitting target positioned within 1.500 m of the muzzle.
· Delayed action allows the round to pass through target shield and to explode behind.
· The fuze guarantees self-destruction of the round within 3.500 m from the muzzle.
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 armed within 5 to 20 m from muzzle. At firing the set-back forces arm the fuze, fixing the elements of the fire train in one line.
Upon impact, the fuze provides delay of 0.02 sec.
In case of no impact the round is self-destruct within 3.5 to 6 s.
