Omaha Beach on June 9, 1944, showing a number of U.S. Navy landing ships tank (LST), unloading reinforcements, heavy weapons and additional supplies. Several of the LSTs and smaller transports in the makeshift harbor carried barrage balloons as a defense against low-flying German aircraft. However, the German Luftwaffe barely showed its presence on D-Day and the days following the landings. (Courtesy photo)
