Bangor-class minesweeper

Bangor-class minesweeper

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.

Royal Canadian Navy

Royal Canadian Navy

The Royal Canadian Navy is the naval force of Canada. The RCN is one of three environmental commands within the Canadian Armed Forces. As of 2021, the RCN operates 12 frigates, four attack submarines, 12 coastal defence vessels, eight patrol class training vessels, two offshore patrol vessels, and several auxiliary vessels. The RCN consists of 8,570 Regular Force and 4,111 Primary Reserve sailors, supported by 3,800 civilians. Vice-Admiral Angus Topshee is the current commander of the Royal Canadian Navy and chief of the Naval Staff.

World War II

World War II

World War II or the Second World War, often abbreviated as WWII or WW2, was a global conflict that lasted from 1939 to 1945. The vast majority of the world's countries, including all of the great powers, fought as part of two opposing military alliances: the Allies and the Axis. Many participants threw their economic, industrial, and scientific capabilities behind this total war, blurring the distinction between civilian and military resources. Aircraft played a major role, enabling the strategic bombing of population centres and the delivery of the only two nuclear weapons ever used in war.

Battle of the St. Lawrence

Battle of the St. Lawrence

The Battle of the St. Lawrence involved marine and anti-submarine actions throughout the lower St. Lawrence River and the entire Gulf of Saint Lawrence, Strait of Belle Isle, Anticosti Island and Cabot Strait from May–October 1942, September 1943, and again in October–November 1944. During this time, German U-boats sank over 20 merchant ships and four Canadian warships. There were several near-shore actions involving the drop of German spies, or the attempted pickup of escaping prisoners of war. Despite the 23 ships lost, this battle marked a strategic victory for Canadian forces as ultimately they managed to disrupt U-boat activity, protect Canadian and Allied convoys, and intercept all attempted shore operations. This marked the first time that a foreign power had inflicted casualties in Canadian inland waters since the US incursions in the War of 1812.

Battle of the Atlantic

Battle of the Atlantic

The Battle of the Atlantic, the longest continuous military campaign in World War II, ran from 1939 to the defeat of Nazi Germany in 1945, covering a major part of the naval history of World War II. At its core was the Allied naval blockade of Germany, announced the day after the declaration of war, and Germany's subsequent counter-blockade. The campaign peaked from mid-1940 through to the end of 1943.

Ship breaking

Ship breaking

Ship-breaking is a type of ship disposal involving the breaking up of ships for either a source of parts, which can be sold for re-use, or for the extraction of raw materials, chiefly scrap. Modern ships have a lifespan of 25 to 30 years before corrosion, metal fatigue and a lack of parts render them uneconomical to operate. Ship-breaking allows the materials from the ship, especially steel, to be recycled and made into new products. This lowers the demand for mined iron ore and reduces energy use in the steelmaking process. Fixtures and other equipment on board the vessels can also be reused. While ship-breaking is sustainable, there are concerns about the use by poorer countries without stringent environmental legislation. It is also labour-intensive, and considered one of the world's most dangerous industries.

Vegreville

Vegreville

Vegreville is a town in central Alberta, Canada. It is on Highway 16A approximately 103 km (64 mi) east of Edmonton, Alberta's capital city. It was incorporated as a town in 1906, and that year also saw the founding of the Vegreville Observer, a weekly newspaper for the region.

Alberta

Alberta

Alberta is one of the thirteen provinces and territories of Canada. It is part of Western Canada and is one of the three prairie provinces. Alberta is bordered by British Columbia to the west, Saskatchewan to the east, the Northwest Territories (NWT) to the north, and the U.S. state of Montana to the south. It is one of the only two landlocked provinces in Canada. The eastern part of the province is occupied by the Great Plains, while the western part borders the Rocky Mountains. The province has a predominantly continental climate but experiences quick temperature changes due to air aridity. Seasonal temperature swings are less pronounced in western Alberta due to occasional Chinook winds.

Design and description

A British design, the Bangor-class minesweepers were smaller than the preceding Halcyon-class minesweepers in British service, but larger than the Fundy class in Canadian service.[3][4] They came in two versions powered by different engines; those with a diesel engines and those with vertical triple-expansion steam engines.[3] Vegreville was of the latter design and was larger than her diesel-engined cousins. Vegreville was 180 feet (54.9 m) long overall, had a beam of 28 feet 6 inches (8.7 m) and a draught of 9 feet 9 inches (3.0 m).[3][5] The minesweeper had a displacement of 672 long tons (683 t). She had a complement of 6 officers and 77 enlisted.[5]

Vegreville had two vertical triple-expansion steam engines, each driving one shaft, using steam provided by two Admiralty three-drum boilers. The engines produced a total of 2,400 indicated horsepower (1,800 kW) and gave a maximum speed of 16.5 knots (30.6 km/h; 19.0 mph). The minesweeper could carry a maximum of 150 long tons (152 t) of fuel oil.[3]

In general, Bangor-class minesweepers were armed with either a single quick-firing (QF) 12-pounder (3 in (76 mm)) 12 cwt HA gun or a QF 3-inch (76 mm) 20 cwt gun mounted forward.[3][5][a] The ships were also fitted with a QF 2-pounder Mark VIII aft and were eventually fitted with single-mounted QF 20 mm Oerlikon guns on the bridge wings. The 2-pounder gun aboard Vegreville was replaced by a powered twin 20 mm Oerlikon mount.[6] Those ships assigned to convoy duty were armed with two depth charge launchers and four chutes to deploy their 40 depth charges.[3][6] Vegreville was equipped with LL and SA minesweeping gear to counter magnetic and acoustic naval mines.[6]

Halcyon-class minesweeper

Halcyon-class minesweeper

The Halcyon class was a class of 21 oil-fired minesweepers built for the British Royal Navy between 1933 and 1939. They were given traditional small ship names used historically by the Royal Navy and served during World War II.

Fundy-class minesweeper

Fundy-class minesweeper

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.

Diesel engine

Diesel engine

The diesel engine, named after Rudolf Diesel, is an internal combustion engine in which ignition of the fuel is caused by the elevated temperature of the air in the cylinder due to mechanical compression; thus, the diesel engine is called a compression-ignition engine. This contrasts with engines using spark plug-ignition of the air-fuel mixture, such as a petrol engine or a gas engine.

Length overall

Length overall

Length overall is the maximum length of a vessel's hull measured parallel to the waterline. This length is important while docking the ship. It is the most commonly used way of expressing the size of a ship, and is also used for calculating the cost of a marina berth.

Beam (nautical)

Beam (nautical)

The beam of a ship is its width at its widest point. The maximum beam (BMAX) is the distance between planes passing through the outer extremities of the ship, beam of the hull (BH) only includes permanently fixed parts of the hull, and beam at waterline (BWL) is the maximum width where the hull intersects the surface of the water.

Draft (hull)

Draft (hull)

The draft or draught of a ship's hull is the vertical distance between the waterline and the bottom of the hull (keel). The draught of the vessel is the maximum depth of any part of the vessel, including appendages such as rudders, propellers and drop keels if deployed. Draft determines the minimum depth of water a ship or boat can safely navigate. The related term air draft is the maximum height of any part of the vessel above the water.

Displacement (ship)

Displacement (ship)

The displacement or displacement tonnage of a ship is its weight. As the term indicates, it is measured indirectly, using Archimedes' principle, by first calculating the volume of water displaced by the ship, then converting that value into weight. Traditionally, various measurement rules have been in use, giving various measures in long tons. Today, tonnes are more commonly used.

Knot (unit)

Knot (unit)

The knot is a unit of speed equal to one nautical mile per hour, exactly 1.852 km/h. The ISO standard symbol for the knot is kn. The same symbol is preferred by the Institute of Electrical and Electronics Engineers (IEEE), while kt is also common, especially in aviation, where it is the form recommended by the International Civil Aviation Organization (ICAO). The knot is a non-SI unit. The knot is used in meteorology, and in maritime and air navigation. A vessel travelling at 1 knot along a meridian travels approximately one minute of geographic latitude in one hour.

Fuel oil

Fuel oil

Fuel oil is any of various fractions obtained from the distillation of petroleum. Such oils include distillates and residues. Fuel oils include heavy fuel oil, marine fuel oil (MFO), bunker fuel, furnace oil (FO), gas oil (gasoil), heating oils, diesel fuel and others.

Bridge (nautical)

Bridge (nautical)

The bridge, also known as the pilothouse or wheelhouse, is a room or platform of a ship from which the ship can be commanded. When a ship is under way, the bridge is manned by an officer of the watch aided usually by an able seaman acting as a lookout. During critical maneuvers the captain will be on the bridge, often supported by an officer of the watch, an able seaman on the wheel and sometimes a pilot, if required.

Depth charge

Depth charge

A depth charge is an anti-submarine warfare (ASW) weapon. It is intended to destroy a submarine by being dropped into the water nearby and detonating, subjecting the target to a powerful and destructive hydraulic shock. Most depth charges use high explosive charges and a fuze set to detonate the charge, typically at a specific depth. Depth charges can be dropped by ships, patrol aircraft, and helicopters.

Naval mine

Naval mine

A naval mine is a self-contained explosive device placed in water to damage or destroy surface ships or submarines. Unlike depth charges, mines are deposited and left to wait until they are triggered by the approach of, or contact with, any vessel or a particular vessel type, akin to anti-infantry vs. anti-vehicle mines. Naval mines can be used offensively, to hamper enemy shipping movements or lock vessels into a harbour; or defensively, to protect friendly vessels and create "safe" zones. Mines allow the minelaying force commander to concentrate warships or defensive assets in mine-free areas giving the adversary three choices: undertake an expensive and time-consuming minesweeping effort, accept the casualties of challenging the minefield, or use the unmined waters where the greatest concentration of enemy firepower will be encountered.

Service history

Vegreville was ordered as part of the 1940–41 shipbuilding programme. The minesweeper's keel was laid down on 2 June 1941 by Canadian Vickers Ltd. at Montreal, Quebec. The ship was launched on 7 October later that year. Vegreville was commissioned into the Royal Canadian Navy on 10 December 1941 at Montreal with the pennant number J257.[7]

After commissioning, Vegreville was assigned to the Western Local Escort Force as a convoy escort. In June 1942 she was reassigned to the Gulf Escort Force and moved again in September to Newfoundland Force.[7]

In January 1944, Vegreville was ordered to the United Kingdom as part of Canada's contribution to the invasion of Normandy. In the lead up to the invasion, she moved between the 32nd, 31st and finally the 14th Minesweeping Flotilla, with whom she fought with on D-Day.[7][8] The 14th flotilla was assigned to sweep channel 2 of mines in the American sector.[8] During the night of 5–6 June, the flotilla swept the assault channel unmolested by German shore positions.[9] The 14th Minesweeping Flotilla resumed minesweeping activities an hour after the assault began on 6 June. They swept Baie de la Seine until 13 June.[10] The 14th flotilla continued minesweeping activities in the invasion area until 21 June.[11] Vegreville remained in UK waters until September of that year.[7]

In September 1944, Vegreville returned to Canada and underwent a refit at Sydney. Following its completion, the ship was ordered back to the UK, arriving in February 1945.[7] She joined the 31st Minesweeping Flotilla after returning to the UK. In April 1945, the 31st Minesweeping Flotilla joined the last large-scale combined operation in the European theatre in an attack on German naval bases in France that had been left untouched by Allied war effort to that point. Departing Plymouth on 12 April, the 31st Minesweeping Flotilla began operations in the mouth of the Gironde estuary on 14 April. They completed their duties on 16 April, unmolested by the Germans. While returning to Plymouth, the flotilla encountered a German trawler and captured it.[12] On 23 April 1945 she suffered severe damage to her port engine in the English Channel off France and was forced to return to port. Once there she was declared a total constructive loss and beyond economical repair. She was paid off on 6 June 1945 and laid up at Falmouth.[7] The ship remained there until taken to Hayle in May 1947 to be broken up.[13]

Keel

Keel

The keel is the bottom-most longitudinal structural element on a vessel. On some sailboats, it may have a hydrodynamic and counterbalancing purpose, as well. The laying of the keel is often the initial step in the construction of a ship. In the British and American shipbuilding traditions, this event marks the beginning date of a ships construction.

Canadian Vickers

Canadian Vickers

Canadian Vickers Limited was an aircraft and shipbuilding company that operated in Canada during the early part of the 20th century until 1944. A subsidiary of Vickers Limited, it built its own aircraft designs as well as others under licence. Canadair absorbed the Canadian Vickers aircraft operations in November 1944.

Montreal

Montreal

Montreal is the second most populous city in Canada and the most populous city in the province of Quebec. Founded in 1642 as Ville-Marie, or "City of Mary", it is named after Mount Royal, the triple-peaked hill around which the early city of Ville-Marie is built. The city is centred on the Island of Montreal, which obtained its name from the same origin as the city, and a few much smaller peripheral islands, the largest of which is Île Bizard. The city is 196 km (122 mi) east of the national capital Ottawa, and 258 km (160 mi) southwest of the provincial capital, Quebec City.

Quebec

Quebec

Quebec is one of the thirteen provinces and territories of Canada. It is the largest province by area and the second-largest by population. Much of the population lives in urban areas along the St. Lawrence River, between the most populous city, Montreal, and the provincial capital, Quebec City. Quebec is the home of the Québécois nation. Located in Central Canada, the province shares land borders with Ontario to the west, Newfoundland and Labrador to the northeast, New Brunswick to the southeast, and a coastal border with Nunavut; in the south it borders Maine, New Hampshire, Vermont, and New York in the United States.

Ship commissioning

Ship commissioning

Ship commissioning is the act or ceremony of placing a ship in active service and may be regarded as a particular application of the general concepts and practices of project commissioning. The term is most commonly applied to placing a warship in active duty with its country's military forces. The ceremonies involved are often rooted in centuries-old naval tradition.

Pennant number

Pennant number

In the Royal Navy and other navies of Europe and the Commonwealth of Nations, ships are identified by pennant number. Historically, naval ships flew a flag that identified a flotilla or type of vessel. For example, the Royal Navy used a red burgee for torpedo boats and a pennant with an H for torpedo boat destroyers. Adding a number to the type-identifying flag uniquely identified each ship.
