HMS Vindex was a Royal Navy seaplane carrier during the First World War. The ship spent the bulk of her career operating the North Sea, where she twice unsuccessfully attacked the German Zeppelin base at Tondern and conducted anti-Zeppelin patrols. One of her Bristol Scout aircraft made the first take-off from an aircraft carrier in late 1915. Another made the first interception of an airship by a carrier-based aircraft on August 2 1916, when it unsuccessfully attacked the Zeppelin LZ17. Vindex was transferred to the Mediterranean in 1918 and was sold back to her original owners in 1920. She was requisitioned again in 1939 and served through World War II as a troopship under a different name. After the end of the war, the ship was returned to her owners and was sold for scrapping in 1954.
