The Tondern raid or Operation F.7, was a British bombing raid by the Royal Navy and Royal Air Force against the Imperial German Navy airship base at Tønder, Denmark, then part of Germany. The airships were used for the strategic bombing of Britain. On 19 July 1918, seven Sopwith Camels took off from HMS Furious, a converted battlecruiser, in the first attack in history by aircraft from an aircraft carrier. For the loss of one man and several aircraft, the British destroyed Zeppelins L 54, L 60 and a captive balloon.
