Rebuilding the US Pacific Fleet

On December 7, 1941, the US Pacific Fleet stationed at Pearl Harbor suffered a devastating surprise attack by the Imperial Japanese Navy. This event marked a pivotal moment in World War II, leading to significant losses and propelling the United States into the war. The American resolve to rebuild the fleet was immediate and unwavering despite the destruction.

In just two hours, the Japanese assault resulted in the sinking of four battleships, damaging four more, and destroying numerous aircraft. The attack caused over 2,400 American casualties and left the Pacific Fleet crippled. The estimated cost of the destruction was staggering, amounting to billions of dollars in today’s currency.

Salvage operations began almost immediately after the attack, focusing on ships that could be repaired and returned to service. These restorable ships included:

• USS West Virginia: Initially sunk, this battleship was successfully raised, repaired, and modernized, returning to service in 1944.
• USS California: Also sunk during the attack, it was refloated, repaired, and rejoined the fleet in 1944.
• USS Nevada: Although heavily damaged, it was beached to avoid sinking, later refloated and repaired, and returned to action by mid-1942.

The restoration process involved innovative techniques like patching hull breaches and pumping out water. Skilled divers and repair crews worked tirelessly to salvage these vessels, showcasing remarkable ingenuity and determination.

Not all ships damaged during the Pearl Harbor attack could be salvaged and returned to service. These unrestorable ships were either too damaged or outdated to warrant repair:

• USS Arizona: The battleship suffered a catastrophic explosion when a bomb detonated its forward magazine, leading to its destruction and the loss of 1,177 crew members. The ship remains a sunken memorial at Pearl Harbor.
• USS Oklahoma: Hit by multiple torpedoes, it capsized and sank, trapping many crew members inside. Although righted and refloated, the extensive damage rendered it unrestorable, and it was eventually scrapped.

Immediately after the attack, efforts were focused on assessing the damage and initiating salvage operations. Despite the extensive destruction, it was determined that many ships could be repaired. The resilience of the US Navy was evident as they began planning the recovery and rebuilding process right away.

Admiral Chester W. Nimitz took command of the Pacific Fleet and led the rebuilding effort. He shifted strategic focus towards aircraft carriers and submarine warfare, moving away from the battleship-centric tactics that had previously dominated naval strategy. This change was crucial for future success in the Pacific Theater.

In addition to repairs, new ships were rapidly constructed. The attack highlighted the need for more aircraft carriers and submarines. Shipyards across the country employed innovative designs and technologies to build ships that would become crucial in the war effort, such as the USS Essex and USS Independence.

By mid-1942, the rebuilt fleet was ready for action. The Battle of Midway, a significant turning point in the Pacific War, showcased the effectiveness of the new strategic focus on carriers. The fleet’s resilience and renewed strength were instrumental in securing Allied victories.
