Vertical aerial view of the Pearl Harbor Navy Yard on 10 December 1941, showing damage from the Japanese raid three days earlier. In upper center is the floating drydock YFD-2, with the destroyer Shaw (DD-373), whose bow was blown off, floating at an angle at one end. The torpedoed cruiser Helena (CL-50) is in Drydock Number Two, in center, for repairs. She was the first ship to use that newly constructed dock. Drydock Number One is just below Drydock Number Two. It holds the relatively undamaged battleship Pennsylvania (BB-38) and the wrecked destroyers Cassin (DD-372), capsized, and Downes (DD-375). Note dark oil streaks on the harbor surface.
