how many uss aircraft carriers have been lost in history?

Answer 1

in US carriers, ph gets it mostly right......except I'd quibble about his use of large.......

Langley was the first US carrier and pretty small, especially compared to Lexington, Hornet, Wasp, and Yorktown, which were all classed as "CV"s or fleet carriers......Princeton was a CVL, a light carrier about half the size of the CV's; the six CVE's were escort carriers, merchant ship hulls with a flight deck slapped on them as an emergency expedient in 1940-41 and about 1/3 the size of fleet carriers....meant to fight German subs in the North Atlantic, Gambier Bay was sunk by Japanese cruisers and battleships off Leyte in 1944

so Princeton, 1944, was the last time a US carrier was sunk by enemy action.....

and in 1943, for about 4 months the US Pacific Fleet was down to ONE operational carrier...her name was Enterprise and Gene Roddenberry named a class of starships for her....

Answer 2

12 - that I can find for sure (all American Navy)
6 fleet carriers (large size)
Lexington
Langly
Saratoga
Yorktown
Hornet
Princeton
plus 6 escort carriers (small size)
all lost in WWII between 1942 and 1945
as far as other countries most of 'em never saw any real combat I don't know of any (except I THINK one english carrier that may have gone down - not quite sure)

Answer 3

None. They know where everyone of them are.
