The Admirable class was one of the largest and most successful classes of minesweepers ordered by the United States Navy during World War II. Typically, minesweepers detected and removed naval mines before the rest of the fleet arrived, thereby ensuring safe passage for the larger ships. They were also charged with anti-submarine warfare (ASW) duties with rear-mounted depth charge racks and a forward-firing Hedgehog antisubmarine mortar. Their job was essential to the safety and success of U.S. naval operations during World War II and the Korean War. These minesweepers were also employed as patrol vessel and convoy escorts.

The PCE-842-class patrol craft escort was a United States Navy (USN) ship class of submarine chasers designed during World War II. The PCE-842-class were the only vessels ever designated by the USN as the 'patrol craft escort' (PCE) type. The PCE design was derived from the 180-foot (55 m) Admirable-class minesweeper to complement 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 but with a less powerful engine also much slower; however, because of its larger size, the PCE was able to undertake longer-range tasks over PC-461-class vessels. The USN envisaged the PCE as enabling PCs and smaller vessels to undertake coastal patrols without being called-upon as often to perform open ocean and convoy escort duties, while simultaneously freeing-up some larger vessels - such as destroyer escorts and destroyers - from convoy ASW duties. The PCE-482-class had a standard crew complement of 99 officers and men. The class would ultimately see 68 total vessels built, serving with multiple navies around the world.
