F1



The F-1 hand grenade, nicknamed the limonka (lemon grenade ) is an anti-personnel fragmentation, or 'defensive' grenade. It contains a 60 gram explosive charge (TNT). The total weight of the grenade with the fuze is about 600 grams. The UZRGM fuze is a universal Russian type also used in the RG-41, RG-42, and RGD-5 grenades. The standard time delay for this fuze is 3.5 to 4 seconds. However, UZRGM fuze variants are available which give delays between zero (i.e. instantaneous) and 13 seconds, specifically for use in booby-traps.

The F1 was introduced during WW2 and subsequently redesigned post-war. It has a steel exterior that is ribbed to facilitate fragmentation upon detonation and to prevent hands from slipping. The distance the grenade can be thrown is estimated at 30-45 meters. The radius of the shrapnel dispersion is up to 200 meters (effective radius is about 30 meters, by some sources).
