The Tondern raid, officially designated Operation F.7, was a British bombing raid mounted by the Royal Navy and Royal Air Force against the Imperial German Navy's airship base at Tønder, Denmark, then a part of Germany. It was the first attack in history made by aircraft flying from a carrier flight deck. On 19 July 1918 seven Sopwith Camels took off from the converted large cruiser Furious. For the loss of one man, the British destroyed two German zeppelins, L 54 and L 60, and a captive balloon.
