The United States Navy, United States Coast Guard, and United States National Oceanic and Atmospheric Administration (NOAA) use a hull classification symbol to identify their ships by type and by individual ship within a type. The system is analogous to the pennant number system that the Royal Navy and other European and Commonwealth navies use.
USS Haven (AH-12) was the lead ship of her class of hospital ships built for the U.S. Navy during World War II. Laid down as SS Marine Hawk, she was transferred from the Maritime Commission for conversion to a hospital ship, and served in that capacity through the end of the war. She was redesignated APH-112 in June 1946 for participation in Operation Crossroads, returning to her original AP-12 designation in October 1946. Haven participated in the Korean War and eventually ending her military career acting as a floating hospital in Long Beach, California. She was later converted to a chemical carrier and scrapped in 1987.

The Spearhead-class expeditionary fast transport (EPF) is a United States Navy–led shipbuilding program to provide a high-speed, shallow draft vessel intended for rapid intra-theater transport of medium-sized cargo payloads. The EPFs can reach speeds of 35–45 knots, and allow the rapid transit and deployment of conventional or special forces, equipment and supplies.

The PCE-842-class patrol craft were United States Navy patrol craft escorts designed during World War II that were intended for coastal and convoy escort. The design was derived from the 180-foot (55 m) Admirable-class minesweeper as a substitute for the 173-foot (53 m) PC-461-class submarine chasers that were used for anti-submarine warfare (ASW) in coastal areas. At 185 feet long and 640 tons, the PCE is more than twice the displacement of the PC and thus and in combination with a less powerful engine also much slower. It has a crew complement of 99 officers and men.
USNS Brunswick (JHVS-6/T-EPF-6), is the sixth Spearhead-class expeditionary fast transport, currently in service with the United States Navy's Military Sealift Command.
