Firing her 5/38 guns at a target drone aircraft, during exercises, 21 August 1964. The ship following next astern is USS Porterfield (DD-682). The relative positions of Wedderburn's signal flags, with the port side red Bravo flag hoisted higher, indicate that the ship is firing to port. Evenly hoisted flags on Porterfield indicate that her guns are not yet trained out. Photographed by PH2 R.D. Fennell. Official U.S. Navy Photograph.
