Minesweeper
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 ...

Auxiliary Motor Minesweepers
Auxiliary motor minesweepers were small wood-hulled minesweepers commissioned by the United States Navy for service during World War II. The vessels were numbered, but unnamed. The auxiliary motor minesweepers were originally designated yard minesweepers (YMS) and kept the abbreviation YMS after being re-designated. The type proved successful and eventually became the basis for the AMS type of United States Navy minesweeper. Origin of the YMS The Henry B. Nevins Shipyard, Inc., at City Island, Bronx, designed the YMS and laid the keel of the first one, , on 4 March 1941. Launched on 10 January 1942, ''YMS-1'' was completed two months later on 25 March 1942. From keel-laying to completion, the yard built ''YMS-1'' in one year and three weeks. The "Y" designation The first wooden minesweeper of this class was to gain prominence in all theaters during World War II. A total of 561 were built at various U.S. yards. Originally a class of "motor minesweepers" (MS), "Y" was ad ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Naval Mine
A naval mine is a self-contained explosive weapon placed in water to damage or destroy surface ships or submarines. Similar to anti-personnel mine, anti-personnel and other land mines, and unlike purpose launched naval depth charges, they are deposited and left to wait until, depending on their fuzing, they are triggered by the approach of or contact with any vessel. Naval mines can be used offensively, to hamper enemy shipping movements or lock vessels into a harbour; or defensively, to create "safe" zones protecting friendly sea lanes, harbours, and naval assets. Mines allow the minelaying force commander to concentrate warships or defensive assets in mine-free areas giving the adversary three choices: undertake a resource-intensive 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. Although international law requires signatory nations ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
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] [Amazon] |
Royal Navy Reserve
The Royal Naval Reserve (RNR) is one of the two volunteer reserve forces of the Royal Navy in the United Kingdom. Together with the Royal Marines Reserve, they form the Maritime Reserve. The present RNR was formed by merging the original Royal Naval Reserve, created in 1859, and the Royal Naval Volunteer Reserve (RNVR), created in 1903. The Royal Naval Reserve has seen action in World War I, World War II, the Iraq War and the War in Afghanistan. History Establishment The Royal Naval Reserve (RNR) has its origins in the Register of Seamen, established in 1835 to identify men for naval service in the event of war, although just 400 volunteered for duty in the Crimean War in 1854 out of 250,000 on the Register. This led to a Royal Commission on Manning the Navy in 1858 and 1859, which in turn led to the Naval Reserve Act 1859. This established the RNR as a reserve of professional seamen from the British Merchant Navy and fishing fleets, who could be called upon during tim ...

Warship
A warship or combatant ship is a naval ship that is used for naval warfare. Usually they belong to the navy branch of the armed forces of a nation, though they have also been operated by individuals, cooperatives and corporations. As well as being armed, warships are designed to withstand damage and are typically faster and more maneuverable than merchant ships. Unlike a merchant ship, which carries cargo, a warship typically carries only weapons, ammunition and supplies for its crew. In wartime, the distinction between warships and merchant ships is often blurred. Until the 17th century it was common for merchant ships to be pressed into naval service, and not unusual for more than half of a Naval fleet, fleet to be composed of merchant ships—there was not a large difference in construction, unlike the difference between a heavily armoured battleship and an ocean liner. Until the threat of piracy subsided in the 19th century, it was normal practice to arm larger merchant sh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Flower-class Sloop
The Flower class comprised five sub- classes of sloops built under the Emergency War Programme for the Royal Navy during World War I, all of which were named after various flowers. They were popularly known as the "herbaceous borders", in humorous reference to a well-knowadageabout the Royal Navy ("Britain's best bulwarks are her wooden walls"), as well as to a type of garden arrangement popular in the United Kingdom. Fleet minesweepers The Flowers were designed to be built at merchant shipyards, to ease the pressure on yards specializing in warships. The initial three groups were the first purpose-built fleet minesweepers, built with triple hulls at the bow to give extra protection against loss from mine damage when working. When submarine attacks on British merchant ships became a serious menace after 1916, the existing Flower-class minesweepers were transferred to convoy escort duty, and fitted with depth charges, as well as 4.7-inch naval guns. * : first group to b ...

9th Mine Counter-Measures Squadron
The 9th Mine Countermeasures Squadron is a front-line Squadron (naval), squadron of the Royal Navy with responsibility for mine warfare in the Persian Gulf, Persian Gulf region. The squadron is based in Bahrain and, as of 2024-25, is equipped with three mine countermeasure vessels. Normally, a Royal Fleet Auxiliary (RFA) support ship has also been assigned to the squadron. However, in late 2024 the squadron's normal support ship, RFA Cardigan Bay (L3009), RFA ''Cardigan Bay'', returned to the UK for refit and acute personnel shortages in the RFA made her replacement in the Gulf uncertain. In early 2025 the mine countermeasures vessel HMS ''Chiddingfold'' was also returned to the U.K. while the minehunter HMS ''Bangor'' was inactive due to damage sustained in a collision. History 1962–1971 In its original guise, the 9th Mine Sweeping Squadron (MSS) was formed of four Ton-class minesweeper, Ton-class sweepers – HM Ships HMS Appleton, ''Appleton'', HMS Kemerton (M1156), ''Kemerto ...
