HMS Courageous 1st of All Carriers Sunk by Subs

On September 17, 1939, only a couple weeks after World War II in Europe began, the German U-boat, U-29, sunk the British aircraft carrier HMS Courageous with 2 of the 3 torpedoes fired striking the unlucky carrier.  Courageous sank with 519 of her crew going down, becoming the first aircraft carrier ever sunk by a submarine.  Here we list all the aircraft carriers ever sunk in combat by submarines, a dangerous prey as carriers are inevitably well protected by escorting ships.  Note that no aircraft carrier has been sunk in combat from any source since the end of World War II.  World War II is the only conflict so far in which aircraft carriers have been sunk in combat.  Only 3 navies lost aircraft carriers to submarine attack during World War II (or ever), although any naval war that breaks out today would almost certainly pose great risk to carriers from large, fast, silent and deadly modern nuclear subs.
