F1 Grenade Fuse
F1 designates the standard fragmentation hand grenade of the modern australian army otherwise known as the australian defense force.
F1 grenade fuse. The f 1 in its original design was withdrawn from french military service in 1946. It is based on the french f1 grenade and contains a 60 gram explosive charge. It is also nicknamed efka for the letter f. Due to its shape and its yellow green color it is nicknamed the limonka.
The entire f1 unit weighed in at 600 grams and featured a diameter of 55 millimeters. By world war ii the f1 used the m1935 fuse which is a time based fuse but it differs from the m1916 billant fuse internally. It is similar to the american mk 2 pineapple grenade which was also ultimately modeled on the french f1. The system is very conventional in its design and relies on a time fuse detonating an internal high explosive payload hereby firing off shrapnel throughout the surrounding environment.
The total weight of the f1 system was about 600 grams and the total length was about 13 cm. The f1 grenade was initially developed in the early 1940s as a modernized grenade to replace earlier more outdated types. The f1 grenade has a fixed fuse of about 3 seconds unlike the beancan grenade which has a random fuse which can either dud explode in an instant or explode after a millennium. Used in the grenade is the uzrg type fuse which is commonplace for many different types of soviet grenades.
The soviet f1 hand grenade is an anti personnel fragmentation defensive grenade. Designs such as the m1916 and m1917 billant fuses turned the f1 into a time fused grenade which was the grenades final ignition system. The fuse could feature a delay of 0 seconds to 13 seconds this variable nature ensuring that it could be both thrown within a window of relative safety or used as a hidden boobytrap explosive of sorts this triggered by some external means depending on the setup.
