elektronika: Naval mine

Evidence: 100 • authority: 72

A naval mine or sea mine is a self-contained explosive weapon placed in water to damage or destroy surface ships or submarines. Similar to 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 cho…

The action off Lerwick (, "Lerrick") was a naval engagement on 17 October 1917 fought in the North Sea during the First World War. The German light, minelaying cruisers SMS Brummer and Bremse attacked a westbound convoy of twelve colliers and other merchant ships and their escorts, part of the regular Scandinavian convoy. The two escorting destroyers and nine neutral Scandinavian ships were sunk off Shetland, Scotland. Admiralty code breakers had uncovered the call signs of Bremse and Brummer and by direction finding knew that they had sailed from Wilhelmshaven to Lister Tief (Lister Deep) north of Sylt but an operation as far north as the Scandinavian convoy collier route was not anticipat…

The naval operations in the Dardanelles campaign (17 February 1915 – 9 January 1916) took place against the Ottoman Empire during the First World War. Ships of the Royal Navy, French Marine nationale, Imperial Russian Navy (Российский императорский флот) and the Royal Australian Navy, attempted to force a passage through the Dardanelles Straits, a narrow, 41-mile-long (66 km) waterway connecting the Mediterranean Sea with the Sea of Marmara and the Black Sea further north. The naval operations were defeated by the Ottoman defenders, mainly through use of naval mines. The Allies conducted the Gallipoli campaign, a land invasion of the Gallipoli peninsula to eliminate the Ottoman artillery al…

The North Sea Mine Barrage, also known as the Northern Barrage, was a large minefield laid easterly from the Orkney Islands to Norway by the United States Navy (assisted by the Royal Navy) during the First World War. The objective was to inhibit the movement of U-boats from bases in Germany to the Atlantic shipping lanes bringing supplies to the British Isles. Rear Admiral Lewis Clinton-Baker, commanding the Royal Navy minelaying force, described the barrage as the "biggest mine planting stunt in the world's history".

Naval artillery is artillery mounted on a warship, originally used only for naval warfare and then subsequently used for more specialized roles in surface warfare such as naval gunfire support (NGFS) and anti-aircraft warfare (AAW) engagements. The term generally refers to powder-launched projectile-firing weapons and excludes self-propelled projectiles such as torpedoes, rockets, and missiles and those simply dropped overboard such as depth charges and naval mines.

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 were 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 3-inch (76 mm) or 4-inch (102 mm) gun in the bow equipped the tr…

Sea Mine Detection Framework Using YOLO, SSD and EfficientDet Deep Learning Models.. In the context of new geopolitical tensions due to the current armed conflicts, safety in terms of navigation has been threatened due to the large number of sea mines placed, in particular, within the sea conflict areas. Additionally, since a large number of mines have recently been reported to have drifted into the territories of the Black Sea countries such as Romania, Bulgaria Georgia and Turkey, which have intense commercial and tourism activities in their coastal areas, the safety of those economic activities is threatened by possible accidents that may occur due to the above-mentioned situation. The u…
