A minesweeper is a small warship designed to remove or detonate naval mines. Using various mechanisms intended to counter the threat posed by naval mines, minesweepers keep waterways clear for safe shipping.
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 only remaining ship of this class is located at Freedom Park, Omaha, NE.
The Bangor-class minesweepers were a class of warships operated by the Royal Navy (RN), Royal Canadian Navy (RCN), Imperial Japanese Navy (IJN), and Royal Indian Navy (RIN) during the Second World War.
The Ton class were coastal minesweepers built in the 1950s for the Royal Navy, but also used by other navies such as the South African Navy and the Royal Australian Navy. They were intended to meet the threat of seabed mines laid in shallow coastal waters, rivers, ports and harbours, a task for which the existing ocean-going minesweepers of the Algerine class were not suited.
The Belgian Navy, officially the Naval Component of the Belgian Armed Forces, is the naval service of Belgium.
The Auk class were a class of minesweepers serving with the United States Navy and the Royal Navy during World War II. In total, there were 93 Auks built.
The Lapwing-class minesweeper, often called the Bird class, was an early "AM-type" oceangoing minesweeper of the United States Navy. Seven ships of the class were commissioned during World War I, and served well into the 1950s. A number were refitted to serve as ocean-going tugs, salvage vessels, seaplane tenders, or submarine rescue ships.
The Raven class was a class of two World War II-era U.S. Navy minesweepers. They were succeeded by the Auk class which were based on the Ravens but had diesel-electric rather than diesel propulsion.
USS Sentinel may refer to the following ships of the United States Navy:
USS Sentinel (AM-113) was an Auk-class minesweeper built for the United States Navy during World War II; she was the third U.S. Naval vessel to bear the name. It was laid down on 28 November 1941 by the American Ship Building Company, Cleveland, Ohio; launched on 23 May 1942; and commissioned on 3 November 1942.
USS Sentinel (AMCU-39) was a LCI(L)-351-class large landing craft of the United States Navy, later converted to an AMCU-7-class coastal minesweeper.
Naval trawlers are vessels built along the lines of a fishing trawler but fitted out for naval purposes; they were widely used during the First and Second World Wars. Some, known in the Royal Navy as "Admiralty trawlers", were purpose-built to naval specifications; others were adapted from civilian use. Fishing trawlers were particularly suited for many naval requirements because they were robust vessels designed to work heavy trawls in all types of weather, and had large clear working decks. A minesweeper could be created by replacing the trawl with a mine sweep. Adding depth charge racks on the deck, ASDIC sonar below, and a 3-inch (76 mm) or 4-inch (102 mm) gun in the bow equipped the trawler for anti-submarine duties.
The R boats were a group of small naval vessels built as minesweepers for the Kriegsmarine before and during the Second World War. They were used for several purposes during the war, and were also used post-war by the German Mine Sweeping Administration for clearing naval mines.
The Yevgenya class, Soviet designation Project 1258 Korund, are a series of minesweepers built for the Soviet Navy and export customers between 1967 and 1980.
The Craft of Opportunity Program (COOP) was a Royal Australian Navy (RAN) acquisition program intended to supplement the navy's mine warfare capability with civilian vessels that could be quickly converted into minesweepers. Vessels acquired under COOP were not commissioned into the RAN, and instead operated with the prefix "MSA" (Minesweeper Auxiliary).
Project Hula was a program during World War II in which the United States transferred naval vessels to the Soviet Union in anticipation of the Soviets eventually joining the war against Japan, specifically in preparation for planned Soviet invasions of southern Sakhalin and the Kuril islands. Based at Cold Bay in the Territory of Alaska, the project was active during the spring and summer of 1945. It was the largest and most ambitious transfer program of World War II.
HMCS Quinte was a Bangor-class minesweeper constructed for the Royal Canadian Navy during the Second World War. The ship entered service in 1941 and took part in the Battle of the Atlantic. On 30 November 1942, Quinte ran aground and sank off Cape Breton Island. The ship was re-floated and repaired and spent the rest of the war as a training ship. Following the war, the minesweeper was used for naval research until decommissioned in 1946. The vessel was sold for scrap and broken up in 1947.
HMCS Ingonish was a Bangor-class minesweeper initially constructed for the Royal Navy during the Second World War. Loaned to the Royal Canadian Navy in 1942, the vessel served on both coasts of Canada as a convoy escort and patrol vessel. Following the war, the minesweeper was returned to the Royal Navy and laid up. Ingonish was discarded in 1948.
HMCS Mulgrave was a Bangor-class minesweeper that served with the Royal Canadian Navy during the Second World War. Entering service in 1942, the minesweeper took part in the Battle of the Atlantic and the invasion of Normandy. While sweeping for naval mines off France in 1944, the vessel hit one. The ship was towed back to port where Mulgrave was declared a constructive total loss. Laid up until the end of the war, the minesweeper was broken up in 1947.
