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.

Design and description

[edit]

By 1940 the Royal Navy had realized that the Bangor-class minesweepers were too small to carry the equipment needed to handle magnetic mines.[citation needed] A bigger ship was designed, ironically about the same size as the older Halcyon class that the Royal Navy had rejected earlier as too large and expensive for mass production. The size of the new ship made them suitable for use as ocean-going escort ships and many were used to supplement specialist escorts. Most of the ships built for the RCN were solely employed as such and were fitted with more anti-submarine weapons than the RN ships. To maximise production, alternate designs were made to use either steam turbines or reciprocating steam engines.[1] This enabled ships to be built at yards more used to merchant ship design and as with other mass-produced escort vessels (such as the Flower-class corvettes or the River-class frigates, could use merchant-style reciprocating vertical triple expansion (VTE) engines.

Both groups of ships had the same dimensions, although the VTE powered ships had a greater displacement and a deeper draught. The hull measured 225 feet (68.6 m) long overall with a beam of 35 feet 6 inches (10.8 m). The turbine group had a draught of 11 feet (3.4 m) while the reciprocating engined ships sat 1 foot 3 inches (0.4 m) deeper in the water. The turbine-powered ships displaced 850 long tons (860 t) at standard load and 1,125 long tons (1,143 t) at deep load while the reciprocating engined group displaced 1,010–1,030 long tons (1,030–1,050 t) at standard load and 1,305–1,325 long tons (1,326–1,346 t) at deep load. The ships' complement consisted of 85 officers and ratings.[1]

The turbine-powered ships had two Parsons geared steam turbines, each driving one shaft, using steam provided by two Admiralty three-drum boilers. The engines produced a total of 2,000 shaft horsepower (1,500 kW) and gave a maximum speed of 16.5 knots (30.6 km/h; 19.0 mph). The reciprocating engined ships had two vertical triple-expansion steam engines totalling 2,400 indicated horsepower (1,800 kW) and reached the same speed. They carried a maximum of 660 long tons (671 t) of fuel oil that gave them a range of 5,000 nautical miles (9,300 km; 5,800 mi) at 10 knots (19 km/h; 12 mph).[1]

The Algerine class was armed with a QF 4 in (102 mm) Mk V anti-aircraft gun and four twin-gun mounts for Oerlikon 20 mm cannon.[2] The latter guns were in short supply when the first ships were being completed and they often got a proportion of single mounts. By 1944, single-barrel Bofors 40 mm mounts began replacing the twin 20 mm mounts on a one for one basis. All of the ships were fitted for four throwers and two rails for depth charges. Many Canadian ships omitted their sweeping gear in exchange for a 24-bomb Hedgehog spigot mortar and a stowage capacity for 90+ depth charges.[1]

The construction contracts were awarded to shipbuilders in both the United Kingdom and Canada.

Construction

[edit]

A total of 94 Algerine class vessels served with the Royal Navy; of these 45 were built in the UK and another 49 in Canada. A further 12 vessels served with the Royal Canadian Navy; all these were built in Canada.

The ships were built in the UK were ordered under the 1940 to 1943 war emergency building programmes. The companies involved were Harland & Wolff (22), Lobnitz (18), Blyth (2), Fleming & Ferguson (1) and William Simons (2). Another 15 were ordered in 1943 but cancelled, to free yard space for building Loch-class frigates. The ships were built in two types; 26 powered by steam turbine and 22 by reciprocating or vertical triple expansion (VTE) steam engines. The turbine powered ships were all built by Harland & Wolff, save two, built at Blyth; the VTE powered ships were built at Lobnitz, Simons and Fleming & Ferguson.[3]

Of the ships built in Canada, the companies involved were Toronto Shipbuilding (later Redfern), Port Arthur and Collingwood. All the Canadian-built ships were VTE powered. Only 12 of these ships served with the RCN; a further 17 were built for the RCN but transferred to the Royal Navy in exchange for an equal number of Castle-class corvettes, as the RCN was in need of escort vessels. Fourteen ships were built for the United States Navy, but again were transferred to the RN on completion under Lend-Lease. Nineteen ships were ordered directly by the RN under the 1943 programme; a further six ships were ordered, but cancelled.[4]

Service history

[edit]

The Algerine class vessels in service with the Royal Navy were employed mainly as minesweepers, though they were equipped as anti-submarine warfare vessels also, and could serve as escort ships as needed. Their ASDIC and depth-charge equipment was equal to that of the Flower-class corvettes or even River-class frigates, though they were not equipped with forward-firing weapons like Hedgehog. Five Algerines were sunk in action, and four others were declared constructive total losses after sustaining damage.[5] The Algerines of the Royal Canadian Navy by contrast were employed as escorts. They were not fitted with mine-sweeping gear, though they were optimized for service in the Arctic. The Algerines served principally as senior ships in Canadian escort groups of the Western Local Escort Force and the Halifax Force. No RCN vessels of the class were lost.[6]

Post-war service

[edit]

After the war, a number of Algerines continued in service as patrol boats, survey ships, and training ships. On 11 March 1959, HMS Acute and HMS Jewel, training ships at Dartmouth, rescued the burning German coaster Vorman Rass, off Start Point, Devon.[7] At least one, HMS Pickle, was still engaged in minesweeping duties in British waters as late as 1955. All Algerines in RN and RCN service were disposed of by the late 1950s or early 1960s.[8]

Some were sold to other navies or into merchant service. The fourteen ships under Lend-Lease were returned to the USN in 1946; five of these later transferred to the Greek Navy. Of the RN ships, five were transferred to the Belgian Navy, two to South Africa and two to Ceylon; another five, one apiece, were acquired by Burma, Nigeria, Italy, Iran, and Thailand. Two RCN ships were transferred to Belgium in 1959 as replacements for two ex-RN ships that were due for disposal. One, HTMS Phosampton (ex-HMS Minstrel), was in service until 2012 with the Royal Thai Navy.
