The U.S.S.Block Island CVE-21 which was sunk by a German U-Boat during World War 2 was the only U.S. Navy Carrier to be lost in the Atlantic Ocean.

The view from the telescope of the German U-Boat that just fired the torpedo that sank the U.S.S.Block Island CVE-21 you can see the trace line in the water of the torpedo's path after being fired. Revenge was swift a U.S. Destroyer Escort sank the German U-Boat with all hands with depth charges.
