Abstract : This patent discloses an air delivered armor piercing and anti-personnel munition which includes a pair of spin latched overlay hemispherical shells whose outer surface is fluted and which encase the fragmentation grenade munition. One of the shells is affixed to the munition by a lanyard so that when the munition is released it will be caused to spin by the fluted surface which in turn will result in unlatching of the shells and release of one while the other (drag hemisphere) acts to limit the descent velocity and maintains the munition in an upright position. The grenade is provided with spring loaded standoff legs which are retracted when the grenade is within the shell but assume their extended downward position upon release of the outer shells. The shell separation also initiates the arming of the grenade fuze. The interial force generated by the impact impales the grenade firing pin in the detonator thus commencing the detonation train. The grenade includes an outer fragmentation housing which is fragmented by detonation of the internally shaped high explosive charge. (Author)
