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.
Orders were placed at shipyards in Britain, Canada and India for the Royal Navy, the Royal Canadian Navy and the Royal Indian Navy.
Two vessels, Basset and Mastiff, were built by Henry Robb, of Leith. The main difference between them was that Basset had coal-fired, and Mastiff had oil-fired, engines. [1] With the onset of war, Bassett served as the prototype for a series of Admiralty trawlers, of which a total of 180 were built during the conflict using a variety of naming schemes. The first 20 vessels were ordered under the 1939 programme (the Tree class), 30 vessels under the 1939 War Emergency programme in two groups (20 Dance class, and 10 Shakespearian class), and a further 130 over the next four years (the Western Isles (or, simply, Isles) class). [2]
Four vessels were built for the Royal Canadian Navy at various yards; [1] these ships had strengthened hulls to cope with pack ice conditions and were also known as the Fundy class.
A further 16 vessels were ordered from Canadian shipyards in the war years, also bearing Canadian names. These were for the Royal Navy, though eight of these were transferred on completion to the Royal Canadian Navy. These are usually referred to as Canadian Isles-class trawlers. [3]
A total of 50 vessels were ordered from Indian yards (including two for the Ceylon Government) [4] though in the event more than half were cancelled. [5] Twenty-two were completed during the war; [1] another 25 were cancelled and four were destroyed before completion when invading Japanese forces in 1942 over-ran their shipyards in Burma. [5] These vessels bore the names of Indian cities, but are variously referred to as Indian Basset class [1] or Indian Isles class trawlers. [5]
HMS Baffin was an Isles-class trawler of the Royal Navy. Constructed in Canada for the Royal Navy, the trawler was one of eight loaned to the Royal Canadian Navy during the Second World War. The vessel was mostly engaged in minesweeping duties out of Halifax, Nova Scotia. Following the war, Baffin was returned to the Royal Navy. The vessel was then sold into mercantile service. The vessel was broken up in 1983.
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.
The Town-class destroyers were a group of 50 destroyers of the Royal Navy and the Royal Canadian Navy that were in service during the Second World War. They were transferred from the United States Navy in exchange for military bases in the British West Indies and Newfoundland, as outlined in the Destroyers for Bases Agreement between the United Kingdom and United States, signed on 2 September 1940. They were known as "four-pipers" or "four-stackers" because they had four smokestacks (funnels). Later classes of destroyers typically had one or two.
HMCS St Julien was one of twelve Battle-class naval trawlers constructed for and used by the Royal Canadian Navy (RCN) during the First World War. Following the war the ship was transferred to the Canadian Department of Marine and Fisheries and converted into a lightvessel. Re-designated Lightship No. 22, the ship remained as such until 1958. The ship was sold for commercial use and renamed Centennial and was in service until 1978.
HMS Albury was a Hunt-class minesweeper of the Aberdare sub-class built for the Royal Navy during World War I. She was not finished in time to participate in the First World War and survived the Second World War to be sold for scrap in 1947.
The Fundy-class minesweepers were a class of four minesweepers operated by the Royal Canadian Navy during the Second World War. All four ships entered service in 1938 and the class were discarded in 1945, sold for mercantile service. Three ended up sold to Chinese interests, while one remained active in Canada until 1987.
HMCS Fundy was a Fundy-class minesweeper that served in the Royal Canadian Navy from 1938 to 1945. The minesweeper was the first warship built for Canada since 1918. She saw service in the Atlantic Ocean during the Second World War. The vessel was named for the Bay of Fundy. After the war she had an extensive civilian career.
A danlayer was a type of vessel assigned to minesweeping flotillas during and immediately after World War II. They were usually small trawlers, fitted for the purpose of laying dans. A dan is a marker buoy which consists of a long pole moored to the seabed and fitted to float vertically, usually with a coded flag at the top.
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 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 Type 139 patrol trawler was a class of vessel used as a training ship by the Federal German Navy. Both vessels in the class were originally built for the Royal Navy in 1942 as Isles-class naval trawlers.
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.
HMIS Kathiawar (J155) was a Bangor-class minesweeper built for the Royal Navy, but transferred to the Royal Indian Navy (RIN) during the Second World War.
HMIS Baluchistan (J182) was a Bangor-class minesweeper built for the Royal Navy, but transferred to the Royal Indian Navy (RIN) during the Second World War.
HMIS Rajputana (J197) was a Bangor-class minesweepers built for the Royal Navy, but transferred to the Royal Indian Navy (RIN) during the Second World War.
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 Military class of Admiralty trawlers was a small class of trawlers built for the Royal Navy during the Second World War.
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.
HMS Pellew was a Admiralty M-class destroyer which served with the Royal Navy during the First World War. The M class were an improvement on the preceding L class, capable of higher speed. Launched on 18 April 1916, the vessel served with the Grand Fleet escorting convoys. The vessel was part of an unsuccessful attempt by the navy to trap the German submarines that had taken such a heavy toll on merchant shipping in December 1917. The action involved an eight-ship convoy consisting of four merchant vessels escorted by two armed trawlers and the sister ships Pellew and Partridge. Instead of submarines, four German destroyers attacked, sinking all but one member of the convoy and disappearing before the light cruisers which were to be the spring in the trap could arrive. Pellew, the sole survivor, took refuge in a Norwegian fjord. After the armistice that ended the war, the destroyer was placed in reserve and subsequently sold to be broken up on 9 May 1921.
