ABSTRACT:
A helicopter armament system includes an elongated support plank longitudinally extending transversely through the helicopter and having opposite end portions projecting outwardly beyond opposite sides of the helicopter. Mounted on these opposite plank end portions are a pair of 0.50 caliber machine guns supplied with belted ammunition by two ganged pairs of ammunition magazine boxes supported within the cabin area, on the top side of the plank, by roller support structures operable to isolate the boxes from forces arising from plank flexure, and to significantly facilitate operative attachment of the boxes to the plank and subsequent removal of the boxes therefrom. Using specially designed inserts and lid structures, each of the boxes may be rapidly converted between 0.50 caliber and 7.62 mm ammunition belt storage and outfeed, and the same boxes may be used individually or ganged in a two or four box group to feed a 0.50 caliber machine gun, or used individually or ganged in a two box group to feed a 7.62 mm machine gun.
