The Isles-class trawlers were a class of naval trawler used by the Royal Navy, Royal Canadian Navy and Royal New Zealand Navy during World War II.
HMS Mariner was a reciprocating engine-powered Algerine-class minesweeper during the Second World War. Laid down as HMCS Kincardine for the Royal Canadian Navy she was transferred on completion to the Royal Navy as HMS Mariner. She survived the war and was sold to Myanmar in 1958 as Yang Myo Aung.
The Algerine-class minesweeper was a large group of minesweepers built for the Royal Navy (RN) and the Royal Canadian Navy (RCN) during the Second World War. 110 ships of the class were launched between 1942 and 1944.
The Royal Naval Patrol Service (RNPS) was a branch of the Royal Navy active during both the First and Second World Wars. The RNPS operated many small auxiliary vessels such as naval trawlers for anti-submarine and minesweeping operations to protect coastal Britain and convoys.
Commissioned minesweepers and danlayers of the Royal New Zealand Navy (RNZN) from its formation on 1 October 1941 to the present. The RNZN was created two years into World War II. For coherence this article covers the war years from the start, and thus includes also the New Zealand minesweepers operating from the beginning of the war.
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.
Naval trawlers were purpose-built or requisitioned and operated by the Royal Navy (RN), mainly during World Wars I and II. Vessels built to Admiralty specifications for RN use were known as Admiralty trawlers. All trawlers operated by the RN, regardless of origin, were typically given the prefix HMT, for "His Majesty's Trawler".
The Shakespearian-class trawler was a series of anti-submarine naval trawlers of the Royal Navy. Ships in the class had a displacement of 545 long tons (554 t), a top speed of 12 knots and a crew of 40 men. The trawlers were armed with a QF 12-pounder [76 mm (3.0 in)] gun, three 20 mm Oerlikon anti-aircraft guns and thirty depth charges. The class was nearly identical to the Isles-class trawlers, of which they are usually considered a subclass. Coriolanus, Horatio and Laertes were lost during the war. Othello, was transferred to Italy in 1946 and Rosalind to Kenya, also in 1946. By the end of that year, only Hamlet and Macbeth remained in service with the Royal Navy; both were sold in 1947.
HMS Providence was a reciprocating engine-powered Algerine-class minesweeper during the Second World War. Laid down as HMCS Forrest Hill for the Royal Canadian Navy she was transferred on completion to the Royal Navy as HMS Providence. She survived the war and was scrapped in 1958.
Tree-class trawlers were a class of anti-submarine naval trawlers which served in the Royal Navy during the Second World War. They were nearly identical to the Isles-class trawlers, of which they are usually considered a subclass.
A naval drifter is a boat built along the lines of a commercial fishing drifter but fitted out for naval purposes. The use of naval drifters is paralleled by the use of naval trawlers.
HMT Laurel was a trawler launched in 1930 that the Admiralty acquired in 1935 and converted to a minesweeper. She served throughout World War II before being sold in 1946. After many years commercial service she was scrapped in 1955.
The Cybele class was a class of trimaran ships, constructed by the Royal Navy during World War II for the purpose of clearing minefields. Referred to as Mine Destructor Vessels, two ships of the class, HMS Cybele and HMS Cyrus were built in 1944; one was lost following D-Day, while the other survived the war only to be scrapped shortly thereafter.
The Kil class was a class of sloops, also referred to as gunboats, built for the Royal Navy during the First World War. They were designed for anti-submarine warfare, but were completed too late in the war to be used extensively in that role. They were designed to be double-ended to confuse submarine observers, and were painted in dazzle camouflage. Following the war, the majority of the class were sold off and converted to coastal cargo vessels.
The Hill class of Admiralty trawlers was a small class of trawlers built for the British Royal Navy during the Second World War.
The Fish class of Admiralty trawlers was a small class of naval trawlers built for the British Royal Navy during the Second World War.
The Basset class of Admiralty trawlers was a class of trawlers built for the British Royal Navy prior to the outbreak of Second World War. The vessels were intended for use as mine-sweepers and for anti-submarine warfare, and the design was based on commercial types, adapted for naval use. The purpose of the order was to make use of specialist mercantile shipyards to provide vessels for war use by adapting commercial designs to Admiralty specifications.
HMS Partridge was a Royal Navy Admiralty M-class destroyer constructed and then operational in the First World War, later being sunk by enemy action in 1917. The destroyer was the sixth Royal Navy vessel to carry the name HMS Partridge.
HMS Grenadier was a Military class trawler of the British Royal Navy, which served as an Anti Submarine Warfare Vessel during the Second World War. The ship was built by Cook, Welton & Gemmell in Beverley, England. She was laid down on 13 June 1942, launched on 26 September 1942 and finally commissioned on 10 February 1943. Her role was to support convoys, and deter attack by German U-boats using depth charges. This class of vessel could be fitted with extra guns, and the Grenadier was reported to have had an extra pair of Oerlikon 20mm guns and a Type 290 mast mounted radar.
HMS Amaranthus (K17) was a Flower-class corvette of the Royal Navy. She took part in the Second World War, being involved in escorting convoys from West Africa to the United Kingdom from May 1941 onwards.
