Советтік F1 қол гранатасы: құрылысы мен қолданылуы

The Soviet F 1 hand grenade (Russian: Фугасный > Fugasnyy 1, "Explosive, Type No. 1") is an anti personnel fragmentation defensive grenade. It is based on the French F1 grenade and contains a explosive charge (TNT). The total weight of the grenade with the fuze is about
Due to its shape and its yellow green color, it is nicknamed the (fem. 'little lemon'). It is also nicknamed Efka (Эфка) for the letter F. It is similar to the American Mk 2 "pineapple grenade", which was also ultimately modeled on the French F 1. F 1 simulation training grenade is called УРГ (учебная ручная граната),URG (training hand grenade).

The Universal'nyi Zapal, Ruchnaya Granata, Modernizirovannyi]] (UZRGM) (Russian for 'universal igniter, hand grenade, improved') fuse is a universal Russian type also used in the RG 41, RG 42, RGO 78, RGN 86 and RGD 5 grenades. The standard time delay for this fuse is 3.5 to 4 seconds. However, UZRGM fuze variants are available which give delays between zero (i. e., instantaneous, specifically for use in booby traps) and 13 seconds. It is possible to hear a loud "pop" as the fuse ignites and begins to burn.

The F 1 was introduced during World War II and subsequently redesigned post war. It has a steel exterior that is notched to facilitate fragmentation upon detonation and to prevent hands from slipping. The distance the grenade can be thrown is estimated at The radius of the fragment dispersion is up to (effective radius is about ,). Hence, the grenade has to be deployed from a defensive position to avoid self harm. About 60 percent of the grenade body pulverizes during the explosion, only 30 percent of the body splits into 290 high velocity, sharp edged splinters each weighing around 1 gram with an initial speed of about .
