Shakespearian-class 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 , a top speed of and a crew of 40 men. The trawlers were armed with a QF 12-pounder [] gun, three Oerlikon 20 mm cannon, 20 mm Oerlikon anti-aircraft guns and thirty depth charges. The class was nearly identical to the s, 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.

Selby
Selby is a market town and civil parish in the Selby District of North Yorkshire, England, south of York on the River Ouse, with a population at the 2011 census of 14,731. The town was historically part of the West Riding of Yorkshire until 1974. Selby once had a large shipbuilding industry, and was an important port on the Selby Canal which brought trade from Leeds. History The town's origins date from the establishment of a Viking settlement on the banks of the River Ouse. Archaeological investigations in Selby have revealed extensive remains, including waterlogged deposits in the core of the town dating from the Roman period onwards. It is believed that Selby originated as a settlement called Seletun which was referred to in the Anglo-Saxon Chronicle of AD 779. The place-name 'Selby' is first attested in a Yorkshire charter , where it appears as ''Seleby''. It appears as ''Selbi'' . The name is thought to be a Scandinavian form of Seletun, meaning ' sallow tree settlemen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Naval Trawler
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 or gun in the bow equipped the trawler for anti-submarine duties. History Armed trawlers were also used to defend fishing groups from enemy aircraft or submarines. The smallest civilian trawlers were converted to danlayers. Contemporary Some nations still use armed trawlers for fisheries protection and patrol. The Indian Navy used naval trawlers for ...

Gunboat Classes
A gunboat is a naval watercraft designed for the express purpose of carrying one or more guns to bombard coastal targets, as opposed to those military craft designed for naval warfare, or for ferrying troops or supplies. History Pre-steam era In the age of sail, a gunboat was usually a small undecked vessel carrying a single smoothbore cannon in the bow, or just two or three such cannons. A gunboat could carry one or two masts or be oar-powered only, but the single-masted version of about length was most typical. Some types of gunboats carried two cannons, or else mounted a number of swivel guns on the railings. The small gunboat had advantages: if it only carried a single cannon, the boat could manoeuvre in shallow or restricted areas – such as rivers or lakes – where larger ships could sail only with difficulty. The gun that such boats carried could be quite heavy; a 32-pounder for instance. As such boats were cheap and quick to build, naval forces favoured swarm ...

Trawlers Of The Royal Navy
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". Summary First World War The trawler Viola, built in 1906 at Hull and requisitioned September 1914 is the oldest surviving steam trawler in the world. She is currently beached at Grytviken in South Georgia, though there are currently plans to return her to Hull. Second World War Requisitioned trawlers There were also 215 trawlers of no specific class These were commercial trawlers that the Admiralty requisitioned. The Royal Navy classified requisitioned trawlers by manufacturer, although such classes were more diverse than traditional naval classifications. Seventy-two requisitioned trawlers were lost.

Operation Dervish (1941)
Operation Dervish was the first of the Arctic Convoys of the Second World War by which the Western Allies supplied material to the Soviet Union against Nazi Germany. Included in the convoy was the personnel and equipment of an RAF Wing, for the air defence of the Russian ports, several civilians and diplomatic missions. The convoy sailed from Liverpool on 12 August 1941 and arrived at Archangelsk on 31 August 1941. There were no attempts by the or the to intercept the convoy and neither side suffered casualties. Co-incident with the Dervish convoy, civilians in the Spitzbergen archipelago were evacuated in Operation Gauntlet (25 August – 3 September 1941) and Dervish was followed by Operation Strength (30 August – 14 September 1941) to transport aircraft for No. 151 Wing RAF at Archangel; both operations succeeded. Background On 22 June 1941, the Soviet Union was invaded by Nazi Germany and its allies. That evening, Winston Churchill broadcast a promise of assistance t ...

Royal East African Navy
The Royal East African Navy was a unified naval force of the former British colonies of Kenya, Tanganyika, Uganda, and Zanzibar. It was the colonial forerunner of the Kenyan Navy and Tanzanian Navy.Gray, Randal, ed., ''Conway's All the World's Fighting Ships 1947–1982, Part II: The Warsaw Pact and Non-Aligned Nations'', Annapolis, Maryland: Naval Institute Press, 1983, , p. 308. Formed in 1953, it was disbanded on 30 June 1962. History The Royal East African Navy (REAN) had its origins in the Kenyan Royal Naval Volunteer Reserve (RNVR), which after the end of World War II in 1945 operated a small naval force in the waters of East Africa. In 1950, the Kenyan RNVR was replaced by the East African Naval Force, which received contributions from both Kenya and Tanganyika, and later Uganda and Zanzibar as well. The East African Naval Force in turn became the REAN in 1953. It replaced the Tanganyikan RNVR (established in 1939) and Sultanate of Zanzibar′s RNVR (established in 1938) as ...

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. Ship displacement varies by a vessel's degree of load, from its empty weight as designed (known as "lightweight tonnage") to its maximum load. Numerous specific terms are used to describe varying levels of load and trim, detailed below. Ship displacement should not be confused with measurements of volume or capacity typically used for commercial vessels and measured by tonnage: net tonnage and gross tonnage. Calculation The process of determining a vessel's displacement begins with measuring its draft.George, 2005. p.5. This is accomplished by means of its "draft marks" (or "load lines"). A mer ...

Royal Navy
The Royal Navy (RN) is the United Kingdom's naval warfare force. Although warships were used by English and Scottish kings from the early medieval period, the first major maritime engagements were fought in the Hundred Years' War against France. The modern Royal Navy traces its origins to the early 16th century; the oldest of the UK's armed services, it is consequently known as the Senior Service. From the middle decades of the 17th century, and through the 18th century, the Royal Navy vied with the Dutch Navy and later with the French Navy for maritime supremacy. From the mid 18th century, it was the world's most powerful navy until the Second World War. The Royal Navy played a key part in establishing and defending the British Empire, and four Imperial fortress colonies and a string of imperial bases and coaling stations secured the Royal Navy's ability to assert naval superiority globally. Owing to this historical prominence, it is common, even among non-Britons, to ref ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anti-submarine
An anti-submarine weapon (ASW) is any one of a number of devices that are intended to act against a submarine and its crew, to destroy (sink) the vessel or reduce its capability as a weapon of war. In its simplest sense, an anti-submarine weapon is usually a projectile, missile or bomb that is optimized to destroy submarines. History Before World War I Prior to about 1890, naval weapons were only used against surface shipping. With the rise of the military submarine after this time, countermeasures were considered for use against them. The first submarine installation of torpedo tubes was in 1885 and the first ship was sunk by a submarine-launched torpedo in 1887. There were only two ways of countering the military submarine initially: ramming them or sinking them with gunfire. However, once they were submerged, they were largely immune until they had to surface again. By the start of the First World War there were nearly 300 submarines in service with another 80 in production ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
