Why Japanese Admirals Were Stunned by How Fast America Replaced Its Carriers

In 1940, the United States passed the Two-Ocean Navy Act and began building a fleet before a single bomb had fallen on Pearl Harbor. By late 1943, a young quartermaster on the USS Saratoga stood on deck and counted thirteen aircraft carriers steaming past him — more than the entire Japanese Navy could put to sea at any one time. This is the story of how America built more than 140 aircraft carriers during World War II while Japan completed only four. From the Essex-class fleet carriers and Independence-class light carriers to Henry Kaiser's Casablanca-class escort carriers (one launched nearly every week), this is the industrial miracle that turned the Pacific War into a one-sided slaughter. It is also the story of the Japanese admirals who knew it was coming — and could not stop it. 00:00 The counting begins 11:40 The Two-Ocean Navy Act 23:20 Essex, Independence, and Casablanca 34:10 Japan's carriers that never came 47:50 The arithmetic of victory If your father, grandfather, or family member served on an American aircraft carrier in the Pacific — Essex, Independence, or Casablanca class — share their name and ship in the comments. These men sailed on towns of steel that helped win the greatest naval war in history. Thank you for watching.
