The carrier wars in the Word war II were a mixture of very pitched battles, submarine sinkings, and sinkings by land based aircraft. Many carriers on each side were lost. How many?
The US Navy lost thirteen aircraft carriers in World War II, one to Germany and twelve to Japan.
The Royal Navy lost eight aircraft carriers in World War II, seven to Germany and one to Japan.
Japan lost twenty aircraft carriers in World War II, all to the US Navy.
That's a total of 41 aircraft carriers sunk in the War (and does not include the two Italian carriers lost at their berths before they were completed, the Nazi carrier, or the French carrier which were not out and out sunk during the war). Think abnout that, 41 carriers sunk. Horrific and costly losses.
At the end of the war:
Japan had three carriers left at the end of World War II which were all scrapped in 1946.
The Royal Navy had fifteen carriers left at the end of World War II, five of which were either scrapped, sold, or loaned to others by 1949. MOst of the Roual Navy carriers were decommissioned and scrapped in the 1950s. Two Royal Navy Wolrd war II carriers made were decomissioned in the 1960s, and one other made it to 1981. However, three served on much longer in foreign service, one to Brazil, one to Argentina, and one to India, which served the longest. Thios was the Colossus Class carrier that later became the INS Vikrant, which was decommissioned in 1997 and the preserved as a Museum. Sadly, the obnly ROyal NAvy World wr II carrier to be preserved.
The United States had thirty one fleet and escort carriers (not counting dozens of "jeep" carriers). Eight of these larger carriers were decomissioned and scrapped, laid up, or transferred before 1950. Most of the World War II Essex carriers served on, after some large refits and refurbs, and were decommissioned in the 1960s and 1970s. A few served well into the 1980s, and two, the Midway and Coral Sea, served into the 1990s. Five of the Essex class carriers re preserved around the United States as
aircraft carrier museum ships.
