Hospital ship USS Haven (AH-12)

USS Haven (AH-12) was the lead vessel of the Haven-class hospital ships constructed for the U.S. Navy during World War II. Originally laid down as SS Marine Hawk, she was transferred from the Maritime Commission for conversion into a hospital ship and served in this role until the end of the war. In June 1946, she was reclassified as APH-112 (evacuation transport) to participate in Operation Crossroads, but in October 1946, she reverted to her original designation, AH-12. Haven also saw service during the Korean War and concluded her military duties as a floating hospital in Long Beach, California. Eventually, she was transformed into a chemical carrier and scrapped in 1987.

Ships of the Type C4 class, like the Haven, were in high demand for commercial use due to their relatively large size and engine configuration. In 1968, Haven was sold by the Maritime Administration, extended by 145 feet (44.2 meters), and converted into the chemical carrier Clendenin. After the conversion was completed, she was renamed Alaskan and served with Union Carbide until she was sold for scrapping in 1987.
