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 Albuquerque (PG-115/PF-7), a Tacoma-class patrol frigate in commission from 1943 to 1945 and from 1950 to 1953, was the first ship of the United States Navy to be named for Albuquerque, New Mexico.

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.
