Abstract
A fragmentation grenade comprises a quantity of high explosive (11) contained within a casing (12, 13) and means (29) for detonating the high explosive (11) so as to cause the casing (12, 13) to disintegrate into a plurality of high velocity fragments (13). The high explosive (11) and the casing (12, 13) are so configured that the fragments (13) are preferentially projected in one or more particular directions relative to the axis (X--X) of the casing (12, 13), and the grenade is provided with a self-righting mechanism (22), whereby the axis can automatically be placed in a desired orientation.
