HMS "Hyperion" was an H-class destroyer built for the Royal Navy during the mid-1930s. During the Spanish Civil War of 1936–1939, the ship enforced the arms blockade imposed by Britain and France on both sides as part of the Mediterranean Fleet. During the first few months of World War II, "Hyperion" searched for German commerce raiders in the Atlantic Ocean and blockaded German merchant ships in neutral harbours until she returned to the British Isles in early 1940. The ship participated in the Norwegian Campaign before she was transferred back to the Mediterranean Fleet shortly afterwards. "Hyperion" participated in the Battle of Calabria and the Battle of Cape Spada in July 1940 while escorting the larger ships of the fleet. The ship covered several convoys to Malta before she struck a mine and was deliberately scuttled in December 1940.
