“...A pair of Nakajima B5N torpedo bombers approached and dropped their torpedoes toward California. Both hit the ship at 08:05, one forward and the other further aft. The former detonated below the armor belt at frame 52 (between number 2 turret and the bridge), creating a hole 10 feet high and 24 feet long, destructively deforming the first torpedo bulkhead and transverse stiffeners between frames 47 and 60, and holing the second bulkhead with fragments. The latter tore a hole that was 40 feet long below the belt armor. The interior torpedo bulkheads nevertheless held and helped to contain the flooding.
The ship had been prepared for inspection at the time of the attack, so the watertight doors had all been opened; the crew was still in the process of closing the doors when the torpedoes struck and flooding began. Many of the portholes and exterior doors were also open for the inspection, which allowed water to enter the ship...”
The ship was repaired and returned to service.
