Abstract: An improved missile, which when in stabilized flight is constituted of upper and lower longitudinal casing portions, a warhead including explosive material confined to the lower casing portion and forming part of the last-mentioned casing portion, the outer surface of the warhead being fragmentized and at its front end, takes the shape broadly of a semicylinder which tapers down in depth (as measured from the horizontal axis of the semicylinder) along the length of the warhead to a curved shape at the rear end but having less depth than at the front end. The same thickness of explosive material is contained in the warhead throughout its length. Thus, the outer surface of the warhead projects upwardly toward said horizontal axis as its rear end is approached to cause the exploded fragments to leave in a direction rearwardly of the warhead in order to increase the lethal effect of the missile.

Abstract: A test model machine gun having an endless ammunition belt continuously moving during operation, a stationary multi-barrel cluster arranged about the gun axis and a combined feed and gunoperating mechanism including a squirrel cage automatically rotatable in orbit about the barrel cluster in synchronism with the moving belt and equipped with a series of ammunition feed spaces, a four-tooth feed sprocket geared to, and thus automatically operable therewith, for removing rounds from the moving belt for their placement in successive squirrel cage-feed spaces, and a bolt-operating drive cam rotatable within, and in simultaneous orbit with, the squirrel cage and incorporating transfer, feed and ejection sprockets automatically rotatable during orbit of the drive cam to respectively engage and transfer rounds from the squirrel cage, feed the transferred rounds to a captive position in the bolt heads and eject the rounds extracted by the bolts for subsequent positioning in alternate squirrel cage-feed spaces. A four-tooth ejection sprocket, geared to the four-tooth feed sprocket and to the drive cam, is simultaneously operative in sequence with rotation of the squirrel cage to engage the extracted rounds returned thereto and replace them in the moving belt.

Abstract: An improved air-to-surface missile having a warhead which is confined solely to the lower half of the missile, and this half contains all the fragments which would normally be distributed throughout both halves of the missile. An upper casing portion need not be employed except to maintain symmetry and aerodynamic stability of the missile as a whole. In order to offset the slewing effect of the fragment pattern at the target on account of a low angle of approach, the fragmented lower surface of the warhead is flattened as it extends toward the rear end and is also curved upwardly so as to approach the longitudinal axis of the missile which contains the warhead.
