If the Pacific War was triggered by the Japanese attack on Pearl Harbor on February 7th, 194 1, and Japan surrendered on August 5th, 1945, the specific number of aircraft carriers built and launched by the United States is as follows:

22 Essex class aircraft carriers

2 midway class aircraft carriers

9 independent light aircraft carriers

Saipan class light aircraft carrier 1

45 Borg-class escort carriers

Commonsmont beach class escort carrier 18.

50 Casablanca-class escort carriers.

There are 24 heavy fleet carriers, light carrier 10 and escort carrier 1 13, totaling 147.

If we start with the outbreak of World War II when Germany invaded Poland on September 1939, we should also add Yorktown-class large aircraft carrier Hornet, escort aircraft carrier Long Beach-II and escort aircraft carrier Sangamon. Then 15 1 ship. This is the data quoted by many authoritative sources.

If you count the aircraft carriers that were basically built during World War II and launched shortly after Japan surrendered (within 1945), you should also add two Essex-class large aircraft carriers, 1 Saipan-class light aircraft carriers and1commencementbeach-class escort aircraft carriers.

To sum up, broadly speaking, the aircraft carriers built by the United States during the whole World War II were 27 large fleet aircraft carriers, 1 1 light aircraft carrier, 1 17 escort aircraft carrier, totaling 155!

However, not all of the above aircraft carriers were used by the US Navy, such as the Borg-class escort aircraft carriers, and most of them were later given to the British Navy for anti-submarine escort operations in the Atlantic Ocean.
