The F1 grenade is a hand grenade used by France during World War I and World War II.

The F1 was a grenade designed during World War I and used by French infantrymen at the time. Originally, the F1 was designed to use a lighter-based ignition system, but later it began using a percussion cap fuse. Designs such as the M1916 and M1917 Billant fuses turned the F1 into a time-fused grenade, which was the grenade's final ignition system. By World War II, the F1 used the M1935 fuse, which is a time-based fuse, but it differs the M1916 Billant fuse internally.

The F1 was used up to World War II, where it served as France's primary fragmentation grenade. The French also used P1 grenades and Citron foug grenades. After the war, the F1 grenade was withdrawn from service.


In addition to the French, several other forces used the F1.

United StatesEdit

The F1 with the M1916 Billant fuse was the preferred grenade by American forces during World War I. The F1 is the inspiration behind the failed American Mk 1 grenade, which in turn spawned the iconic Mk 2 grenade.
