The USS Crossbill (AMc-9) was a Bird-class 2 coastal minesweeper launched in 1937. It was commissioned on March 2, 1941, and served in the U.S. Navy for 6 years until 1947. During its activity, the ship carried a complement of 17 men on board and had its main mission within the 14th Naval District, removing the mines located in the minefields in the water so that other ships could pass safely. Asbestos was prized for its resistance to heat, water, fire, and corrosion, so it could be found in virtually all areas of the Navy vessels, including coastal minesweepers. When asbestos materials start to deteriorate or become damaged, fibers may be released into the air where they can be breathed deep into the lung, causing long-term health problems and fatal respiratory diseases.
