Dance Class Armed Trawler
The Dance class of World War II were armed trawlers of the Royal Navy. They were used for anti-submarine (A/S) and minesweeping work and were nearly identical to the , of which they are usually considered a subclass. One Dance-class trawler (''Sword Dance'') was a war loss, and one (''Saltarelo'') was transferred to Portugal in 1945. Four were transferred to Italy in 1946: ''Gavotte'', ''Hornpipe'', ''Minuet'' and ''Two Step''. None remained in service with the Royal Navy by the end of 1946.

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 World War I, First and World War II, 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 Trawling, 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, Sonar#ASDIC, 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 an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ship Classes Of The Royal Navy
A ship is a large vessel that travels the world's oceans and other navigable waterways, carrying cargo or passengers, or in support of specialized missions, such as defense, research and fishing. Ships are generally distinguished from boats, based on size, shape, load capacity and purpose. Ships have supported exploration, trade, warfare, migration, colonization, and science. Ship transport is responsible for the largest portion of world commerce. The word ''ship'' has meant, depending on the era and the context, either just a large vessel or specifically a ship-rigged sailing ship with three or more masts, each of which is square-rigged. The earliest historical evidence of boats is found in Egypt during the 4th millennium BCE. In 2024, ships had a global cargo capacity of 2.4 billion tons, with the three largest classes being ships carrying dry bulk (43%), oil tankers (28%) and container ships (14%). Nomenclature Ships are typically larger than boats, but there is no u ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Patrol Vessels Of The Portuguese Navy
A patrol is commonly a group of personnel, such as law enforcement officers, military personnel, or security personnel, that are assigned to monitor or secure a specific geographic area. Etymology The word "patrol" is derived from the French word ''patrouiller'', itself derived from the Old French word ''patouiller'' meaning "to paddle, paw about, patrol", which is in turn from ''patte'', "a paw". Military In military tactics, a ''patrol'' is a sub-subunit or small tactical formation, sent out from a military organization by land, sea or air for the purpose of combat, reconnaissance, or a combination of both. The basic task of a patrol is to follow a known route with the purpose of investigating some feature of interest or, in the assignment of a ''fighting patrol'' (U.S. ''combat patrol''), to find and engage the enemy.

Minesweepers Of The Portuguese Navy
A minesweeper is a small warship designed to remove or detonate naval mines. Using various mechanisms intended to counter the threat posed by naval mines, minesweepers keep waterways clear for safe shipping. History The earliest known usage of the naval mine dates to the Ming dynasty.Needham, Volume 5, Part 7, 203–205. Dedicated minesweepers, however, only appeared many centuries later during the Crimean War, when they were deployed by the British. The Crimean War minesweepers were rowboats trailing Grappling hook, grapnels to snag mines. Minesweeping technology picked up in the Russo-Japanese War, using aging torpedo boats as minesweepers. In Britain, naval leaders recognized before the outbreak of World War I that the development of sea mines was a threat to the nation's shipping and began efforts to counter the threat. Sir Arthur Wilson, 3rd Baronet, Sir Arthur Wilson noted the real threat of the time was a blockade aided by mines and not an invasion. The function of the ...

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 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.

20 Mm Oerlikon
The Oerlikon 20 mm cannon is a series of autocannons based on an original German Becker Type M2 20 mm cannon design that appeared very early in World War I. It was widely produced by Oerlikon Contraves and others, with various models employed by both Allied and Axis forces during World War II. Many versions of the cannon are still used. Blowback-operated models History Origins During World War I, the German industrialist Reinhold Becker developed a 20 mm caliber cannon, known now as the 20 mm Becker using the advanced primer ignition blowback (API blowback) method of operation. This used a 20×70mmRB cartridge and had a cyclic rate of fire of 300 rpm. It was used on a limited scale as an aircraft gun on ''Luftstreitkräfte'' warplanes, and an anti-aircraft gun towards the end of that war. Because the Treaty of Versailles banned further production of such weapons in Germany, the patents and design works were transferred in 1919 to the Swiss firm SEMAG (''Seebach Maschi ...
