USS California sank after Japanese torpedo and bomb hits at Pearl Harbor and was later refloated.
California was moored at the harbor when the attack began. Torpedoes opened holes in the hull, while bombs and fires compounded the damage. The ship settled to the bottom over the following days rather than being destroyed beyond recovery.
Salvage teams eventually pumped out the vessel and refloated it in March 1942. California underwent extensive repairs and modernization at the Puget Sound Navy Yard before returning to combat service in 1944.
This history distinguishes California from USS Arizona, which was not refloated after its forward magazines exploded. It also differs from USS Oklahoma, which was raised but never returned to active service.
