This 1963 photograph captures an early U.S. Army UH-1 'Huey' gunship on a Vietnamese airfield, armed with door guns and 2.75-inch rockets visible on the ground nearby. Taken during the earliest phase of American helicopter operations in Vietnam, before the major U.S. troop buildup of 1965, this image documents the pioneering use of armed helicopters that would come to define American airmobile warfare throughout the conflict.
