A US Navy commander and a Lieutenant Commander pose with a number of other officers on the deck of an anchored US warship during World War 1. Low mountains and hills in the background. Aerial views of the US Navy Battleship USS Oklahoma (BB-37) showing the entire ship's company on deck on deck in dress uniforms. Her five 14 inch guns are clearly visible as the aircraft circles the warship. A US Destroyer, in camouflage paint, underway in the harbor, at very slow speed, leaving practically no wake. Note: The USS Oklahoma was one of three U.S. coal burning dreadnaught battleships stationed at Berehaven, Ireland, to guard trans-Atlantic troop convoys against a possible breakout of the German battlecruiser force. (The other ships were the USS Nevada and the USS Utah.)
