RGZ-89 grenade


The RGZ-89 is a modern Polish grenade produced in Zakłady Mechaniczne "Dezamet".

History

In 1987, the Department of Design and Operation of Classical Armaments of the Military University of Technology began work on a new grenade to replace the RG-42 grenades.
The new grenade was to be more effective and at the same time easier and cheaper to produce. It was also required that the fragments of the new grenade, while being highly effective at hitting the target, would not pose a threat to the throwing soldier.
Work began in 1989. The design team consisted of S. Ciepielski, S. Derecki, Z. Jopek, S. Majewski, J. Szymański and E. Włodarczyk.
Initial theoretical calculations were carried out as part of the master's thesis by Second Lieutenant Jacek Walczewski.
After testing several versions of the grenade, the designers decided on a grenade with a plastic body and a fragmentation insert in the form of a spiral duralumin wire. The design work was completed in 1992.
In 1995, the production of the grenade commenced by Zakłady Metalowe Dezamet in Nowa Dęba.
