grenade BER (Defensive hand grenade) developed 1982 g. Development was carried out by two companies, SSPE "Basalt" engaged in buildings and equipment grenades, and near Moscow, a specialized company to provide them with a single fuse DPU, main elements of which are made of high performance plastics molding method. The author of the project. Kuzmin, He conducted and finalized in. Yakunin. Leading performer of works on fuse of was D. Denisov.
Grenade RHS is designed for partial replacement grenades remote actions F-1.
From their predecessors, and it is different design housings, and fuses. The latter was their common, developed based on the experience of combat use of hand grenades and new technological possibilities, allowing to minimize the cost of production.
RGO grenade casing is made of steel. It consists of four hemispheres - two internal and two external. On the inner surface of the hemisphere to facilitate the formation of the fragments have a notch. The lower hemisphere has an outer external knurling. In the upper part of the body seamed cup with thread for screwing the fuse. In the service handling the glass closes traffic jams.
Explosive charge located within the housing. Under the glass is the ignition of the detonator additional checker.
DPU fuse is designed to activate the grenade. Fuse DPU has an interesting design feature. It has two deployment loop: shock and Telecommute (a self-). The chains overlap, and a grenade explosion occurs or from hitting the barrier at the end of long-time charging (1-1,8 sec) or (if the strike did not happen or was not strong enough) after a time of self-destruction (3,2-4,2 sec).
The housing is made of plastic fuse. Inside the body there are parts and components fuse. Nakolno-safety mechanism is designed to ensure the safe handling of a grenade to throw and pinned the primer after throwing grenades.
RGO grenade gives 670-700 fragments weighing 0,46 g and speeds up 1200 m / s. The formation of lethal fragments is 73 % grenade body weight. Energy RGS fragments three times the RGN fragments, the reduced area expansion - 213-286 sq / m. "Controlled fragmentation" RGS provides greater density lesion field, than when a small amount of heavy debris, like F-1, and at the same time, greater security for the metal and its affiliated companies due to rapid loss of energy shards uboinoy.
RGO grenade widely used in the fighting in Afghanistan and in the North Caucasus, and had good reviews.
