Report on Bombing Tests

The ability of airplanes to sink naval vessels with bombs is made the subject of a long report prepared by the Joint Board of the Army and Navy and published at the direction of the Secretary of War and the Acting Secretary of the Navy. The report is a direct result of the series of tests held during June and July last off the Virginia Capes, during which the one time German naval vessels, the submarine U-117, the destroyer G-102, the light cruiser Frankfurt and the battleship Ostfriesland were sunk by aerial bombs.
