How long is the delay from the time a fragmentation grenade is thrown to the time it explodes?

The delay from the time a fragmentation grenade is thrown to the time it explodes is generally designed to be around 4 to 5 seconds. This duration allows the person throwing the grenade to seek cover after releasing it, thereby increasing their safety from the impending explosion.

This timing is essential in combat situations as it gives the thrower a necessary window to take cover while still ensuring the grenade has enough time to travel towards the intended target. Additionally, the mechanism of the grenade is engineered to ensure that the fuse burns for this specific duration before detonation. Knowing this timing is crucial for anyone handling grenades in a military context as it affects tactical planning and personal safety.
