Watch how engineers salvaged almost every sunken ship at Pearl Harbor

Japan's attack on Pearl Harbor caused heavy losses but failed to cripple the US navy

Japan’s air assault sank or damaged 18 warships (including eight battleships) and destroyed 188 aircraft, killing 2,403 Americans, yet all three Pacific Fleet aircraft carriers were absent and survived, and vital infrastructure like oil depots and repair yards remained intact—preserving core US naval power and enabling a rapid recovery.

Recovering the USS Oklahoma was the largest naval salvage operation ever attempted

In 1943, engineers spent three months using 21 giant winches and an intricate cable system to right the capsized USS Oklahoma. It was the largest naval salvage effort ever attempted at the time and remains one of the most complex in history.

Small wooden tail fins modified torpedoes to operate in the harbor's shallow water

Japan's existing Type 91 torpedoes weighed two tons and slammed into the water at 200 mph, diving 150 feet before rising again. Pearl Harbor was only 40 feet deep, requiring engineers to modify the existing torpedoes for the attack.

World War II's Battle of Savo Island was the worst wartime naval defeat in US history

On Aug. 9, 1942, a larger, radar-equipped Allied fleet lost four heavy cruisers off Guadalcanal in the Pacific theater without sinking a single Japanese ship. The Navy kept the humiliating rout secret from the public for years. Experts argued failure resulted from fractured command, not inferior arms or ships.

The US Pacific strategy sought control of key islands to close in on Japan

The US adopted a two-pronged "island hopping" campaign across the Central and Southwest Pacific from 1943–44, deliberately targeting strategically crucial but less-defended islands. This allowed forces to bypass heavily fortified Japanese strongholds and build airfields for bombers aimed at Japan, drastically accelerating the path toward Tokyo while conserving manpower and resources.

What happened to Americans who were in Japan during Pearl Harbor?

When Japan bombed Pearl Harbor in December 1941, roughly 10,000 American civilians were stranded in Japanese-occupied territory.
