In accordance with a request of the Office, Chief of Ordnance, there is being conducted at this arsenal a program of development of improved body armor components. Of interest to this program was a determination of the resistance of a standard flak-jacket to perforation by various fragment- simulating projectiles developed at this arsenal and by standard cal. .45 steel-jacketed ball projectiles. Under impact of the fragment-simulating projectiles the resistance of the flak-jacket is appreciably superior to that of the basic steel component .044 in. of Hadfield manganese steel but under impact of the cal. .45 steel-jacketed ball projectile it is not decisively superior.
