The USS Belleau Wood (CVL-24) was an Independence-class light aircraft carrier active during World War II in the Pacific Theater from 1943 to 1945. The ship took part in extensive wartime operations, including campaigns across the Gilbert, Marshall, Mariana, and Palau Islands from late 1943 to mid-1944. At the Battle of the Philippine Sea, her aircraft helped sink the Japanese carrier "Hiyō". She also fought in the Philippines and participated in the Battle of Leyte Gulf. After being damaged by a kamikaze, she was repaired and supported the invasion of Iwo Jima in 1945. She underwent modifications through 1946. Following the war, she took part in Operation Magic Carpet before being decommissioned and placed in reserve in 1947.
Asbestos contamination resulted from products made with the toxic mineral, which became friable over time. Between 1930 and 1980, asbestos-containing materials were used extensively in the construction of Navy ships. The most hazardous areas on board were the boiler and engine rooms, but, due to poor ventilation, all below-deck spaces were potential sources of contamination.
