The USS Langley was the first aircraft carrier of the United States Navy, built by Mare Island Naval Shipyard in 1911. Named after Samuel Pierpont Langley, the renowned aviation pioneer, the ship was active mainly during World War II. It is worthy of note that the USS Langley was converted from the collier USS Jupiter. As a result of the outstanding achievement of the crew of the ship, the USS Langley was the recipient of a series of awards, including the American Defense Service Medal, the Asiatic-Pacific Campaign Medal, and the World War II Victory Medal. Asbestos exposure was highly prevalent on the ship, particularly in the pump room, the engine room, the propulsion room, and the damage control room. For this reason, people who served aboard the USS Langley should undergo periodical medical examination, as they are at high risk of developing serious diseases such as lung cancer and mesothelioma. In 1942, the ship was scuttled after a Japanese air attack off Java coast.
