Here is a brief summary of US ship losses & damage to the 8 battleships at Pearl Harbor:

Battleship-USS Arizona, heavily damaged by bombs & magazine explosion & sunk; 1,177 killed

Battleship-USS Oklahoma, heavily damaged by 5 to 9 torpedoes, capsized & sunk; 429 killed

Battleship-USS West Virginia, heavily damaged & sunk; 106 killed

Battleship-USS California, 2 torpedoes & 2 bomb hits, sunk in shallow water 2 days later; 105 killed Battleship-USS Nevada, damaged by 2 torpedoes & 5 bombs; beached (not sunk); 57 killed

Battleship-USS Pennsylvania, slight damage from bombs & strafing; 32 killed

Battleship-USS Tennessee, 2 bomb hits, minor damage; 5 killed

Battleship-USS Maryland, 2 bomb hits, some damage; 4 killed

Of the four sunk and one beached: Only the USS Arizona & USS Oklahoma were total losses. The USS West Virginia, USS California, and USS Nevada were all raised/refloated and then repaired & improved on the US west coast in time to fight in the Pacific war. The USS West Virginia required the most time & effort to repair & rebuild. It was refloated on 17 May 1942 and sent to Puget Sound for repairs and returned to service in 1944.

The three battleships not sunk: USS Pennsylvania, USS Tennessee, and USS Maryland were all repaired and improved on the US west coast and returned to service in less than four months.
