USS Langley (CV-1, later AV-3)
USS Langley (CV-1) became the U.S. Navy's first aircraft carrier when commissioned in March 1922. She was converted from USS Jupiter (Collier #3), which was the U.S. Navy's first surface ship propelled by electric motors when commissioned in April 1913. Following tests in the Atlantic in 1924, she became the test platform for developing carrier operating techniques and tactics while serving in the Pacific. Reclassified as a seaplane tender, (AV-3), in 1937, Langley remained on station in the Pacific and supported seaplane patrols and provided aircraft transportation services during the early months of World War II. On February 27, 1942, while transporting U.S. Army P-40's to the Netherlands East Indies, Langley was attacked by Japanese aircraft and was scuttled by her escorting destroyers.
