Photo #: NH 54302 Japanese Type A Midget Submarine At the Pearl Harbor Navy Yard in December 1941. This submarine had been sunk by USS Monaghan (DD-354) in Pearl Harbor during the 7 December 1941 Japanese attack and was subsequently recovered and buried in a landfill. The submarine's hull shows the effects of depth charges and ramming. A hole visible in the after part of the conning tower may be from a 5 shell. The upper background had been overpainted for censorship purposes. Official U.S. Navy Photograph, from the collections of the Naval History and Heritage Command.
