RGM-2 is a mechanical, nose, point-detonating fuze with selectable super-quick or delayed action.



The fuze is designed for High-Explosive, Incendiary and Smoke ammunition for howitzers in the following caliber:

· 122 mm;

· 130 mm;

· 152 mm.



RGM-2 fuze features locking at firing from worn-out or  strongly contaminated barrel. The fuze is safe in storage, handling and operation and ensures the reliable and safe function of the ammunition in all weather conditions.



Operation Modes

The fuze has two operation modes, which are selectable, by built-in setter and wrench:


position “O” for SQ action;

position “З” for delayed action.




Fuze Safety

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.


Fuze Arming

At firing the set-back forces arm the fuze, fixing the elements of the fire train in one line. The fuze is armed within 5 to 20 m from muzzle.


Fuze Action

Upon impact  the fuze provides SQ or delayed action of 0.027 to 0.063 s.

The fuze functions under the impact and inertia forces. The inertia device ensures ignition not only upon impact on solid ground, but also on snow or marshy ground.
