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.<a href="#cite_note-1">[1]</a> Although international law requires signatory nations to declare mined areas, precise locations remain secret, and non-complying parties might not disclose minelaying. While mines threaten only those who choose to traverse waters that may be mined, the possibility of activating a mine is a powerful disincentive to shipping. In the absence of effective measures to limit each mine's lifespan, the hazard to shipping can remain long after the war in which the mines were laid is over. Unless detonated by a parallel <a href="/wiki/Fuze#Time" title="Fuze">time fuze</a> at the end of their useful life, naval mines need to be found and dismantled after the end of hostilities; an often prolonged, costly, and hazardous task.

Offensive mines are placed in enemy waters, outside harbours, and across important shipping routes to sink both merchant and military vessels. Defensive minefields safeguard key stretches of coast from enemy ships and submarines, forcing them into more easily defended areas, or keeping them away from sensitive ones. Shipowners are reluctant to send their ships through known minefields. Port authorities may attempt to clear a mined area, but those without effective minesweeping equipment may cease using the area. Transit of a mined area will be attempted only when strategic interests outweigh potential losses. The decision-makers' perception of the minefield is a critical factor. Minefields designed for psychological effect are usually placed on <a href="/wiki/Trade_route" title="Trade route">trade routes</a> to stop ships from reaching an enemy nation. They are often spread thinly, to create an impression of minefields existing across large areas. A single mine inserted strategically on a shipping route can stop maritime movements for days while the entire area is swept. A mine's capability to sink ships makes it a credible threat, but minefields work more on the mind than on ships.<a href="#cite_note-G&B-4">[4]</a> <a href="/wiki/International_law" title="International law">International law</a>, specifically the Eighth <a href="/wiki/Hague_Conventions_of_1899_and_1907#Hague_Convention_of_1907" title="Hague Conventions of 1899 and 1907">Hague Convention of 1907</a>, requires nations to declare when they mine an area, to make it easier for civil shipping to avoid the mines.

The mines employed were controlled mines, anchored to the bottoms of the harbours, and detonated under control from large mine <a href="/wiki/Casemate" title="Casemate">casemates</a> onshore. During <a href="/wiki/World_War_I" title="World War I">World War I</a>, mines were used extensively to defend coasts, coastal shipping, ports and naval bases around the globe. The Germans laid mines in shipping lanes to sink merchant and naval vessels serving Britain. The Allies targeted the German U-boats in the Strait of Dover and the Hebrides. In an attempt to seal up the northern exits of the North Sea, the Allies developed the <a href="/wiki/North_Sea_Mine_Barrage" title="North Sea Mine Barrage">North Sea Mine Barrage</a>. During a period of five months from June 1918, almost 70,000 mines were laid spanning the North Sea's northern exits. The total number of mines laid in the North Sea, the British East Coast, Straits of Dover, and Heligoland Bight is estimated at 190,000 and the total number during the whole of WWI was 235,000 sea mines.<a href="#cite_note-28">[28]</a> Clearing the barrage after the war took 82 ships and five months, working around the clock.<a href="#cite_note-29">[29]</a> It was also during World War I, that the British <a href="/wiki/Hospital_ship" title="Hospital ship">hospital ship</a>, <a href="/wiki/HMHS_Britannic" title="HMHS Britannic">HMHS Britannic</a>, became the largest vessel ever sunk by a naval mine[<a href="/wiki/Wikipedia:Citation_needed" title="Wikipedia:Citation needed">citation needed</a>].

German submarines also operated in the <a href="/wiki/Mediterranean_Sea" title="Mediterranean Sea">Mediterranean Sea</a>, in the <a href="/wiki/Caribbean_Sea" title="Caribbean Sea">Caribbean Sea</a>, and along the U.S. coast. Initially, contact mines (requiring a ship to physically strike a mine to detonate it) were employed, usually tethered at the end of a cable just below the surface of the water. Contact mines usually blew a hole in ships' hulls. By the beginning of World War II, most nations had developed mines that could be dropped from aircraft, some of which floated on the surface, making it possible to lay them in enemy harbours. The use of dredging and nets was effective against this type of mine, but this consumed valuable time and resources and required harbours to be closed. Later, some ships survived mine blasts, limping into port with buckled plates and broken backs. This appeared to be due to a new type of mine, detecting ships by their proximity to the mine (an influence mine) and detonating at a distance, causing damage with the shock wave of the explosion. Ships that had successfully run the gantlet of the Atlantic crossing were sometimes destroyed entering freshly cleared British harbours. More shipping was being lost than could be replaced, and <a href="/wiki/Winston_Churchill" title="Winston Churchill">Churchill</a> ordered the intact recovery of one of these new mines to be of the highest priority. <figure class="mw-default-size" typeof="mw:File/Thumb"><a href="/wiki/File:L_L_sweeping_gear.jpg" class="mw-file-description"><img src="//upload.wikimedia.org/wikipedia/commons/thumb/3/37/L_L_sweeping_gear.jpg/220px-L_L_sweeping_gear.jpg" decoding="async" width="220" height="167" class="mw-file-element" srcset="//upload.wikimedia.org/wikipedia/commons/thumb/3/37/L_L_sweeping_gear.jpg/330px-L_L_sweeping_gear.jpg 1.5x, //upload.wikimedia.org/wikipedia/commons/thumb/3/37/L_L_sweeping_gear.jpg/440px-L_L_sweeping_gear.jpg 2x" data-file-width="800" data-file-height="607" /></a><figcaption>The towed, electric cables of Double-L, magnetic–minesweeping gear being deployed behind a Royal Navy minesweeper</figcaption></figure> The British experienced a stroke of luck in November 1939, when a German mine was dropped from an aircraft onto the mudflats off <a href="/wiki/Shoeburyness" title="Shoeburyness">Shoeburyness</a> during low tide. Additionally, the land belonged to the army and a base with men and workshops was at hand. Experts were dispatched from <a href="/wiki/HMS_Vernon" title="HMS Vernon">HMS Vernon</a> to investigate the mine. The Royal Navy knew that mines could use magnetic sensors, Britain having developed magnetic mines in World War I, so everyone removed all metal, including their buttons, and made tools of non-magnetic <a href="/wiki/Brass" title="Brass">brass</a>.<a href="#cite_note-31">[31]</a> They disarmed the mine and rushed it to the labs at HMS Vernon, where scientists discovered that the mine had a magnetic arming mechanism. A large ferrous object passing through the Earth's <a href="/wiki/Magnetic_field" title="Magnetic field">magnetic field</a> will concentrate the field through it, due to its magnetic permeability; the mine's detector was designed to trigger as a ship passed over when the Earth's magnetic field was concentrated in the ship and away from the mine. The mine detected this loss of the magnetic field which caused it to detonate. The mechanism had an adjustable sensitivity, calibrated in <a href="/wiki/Gauss_(unit)" title="Gauss (unit)">milligauss</a>. <figure class="mw-default-size" typeof="mw:File/Thumb"><a href="/wiki/File:Dwi_wellington_front.jpg" class="mw-file-description"><img src="//upload.wikimedia.org/wikipedia/commons/thumb/8/8d/Dwi_wellington_front.jpg/220px-Dwi_wellington_front.jpg" decoding="async" width="220" height="150" class="mw-file-element" srcset="//upload.wikimedia.org/wikipedia/commons/thumb/8/8d/Dwi_wellington_front.jpg/330px-Dwi_wellington_front.jpg 1.5x, //upload.wikimedia.org/wikipedia/commons/thumb/8/8d/Dwi_wellington_front.jpg/440px-Dwi_wellington_front.jpg 2x" data-file-width="800" data-file-height="544" /></a><figcaption>A <a href="/wiki/Vickers_Wellington" title="Vickers Wellington">Vickers Wellington</a> fitted with a DWI, magnetic mine exploder, <a href="/wiki/Ismailia" title="Ismailia">Ismailia</a>, Egypt</figcaption></figure> From this data, known methods were used to clear these mines. Early methods included the use of large electromagnets dragged behind ships or below low-flying aircraft (a number of older bombers like the <a href="/wiki/Vickers_Wellington" title="Vickers Wellington">Vickers Wellington</a> were used for this). Both of these methods had the disadvantage of "sweeping" only a small strip. A better solution was found in the "Double-L Sweep"<a href="#cite_note-32">[32]</a> using electrical cables dragged behind ships that passed large pulses of current through the seawater. This created a large magnetic field and swept the entire area between the two ships. The older methods continued to be used in smaller areas. The <a href="/wiki/Suez_Canal" title="Suez Canal">Suez Canal</a> continued to be swept by aircraft, for instance. While these methods were useful for clearing mines from local ports, they were of little or no use for enemy-controlled areas. These were typically visited by warships, and the majority of the fleet then underwent a massive <a href="/wiki/Degaussing#Ships.27_hulls" title="Degaussing">degaussing</a> process, where their hulls had a slight "south" bias induced into them which offset the concentration-effect almost to zero. Initially, major warships and large troopships had a copper degaussing coil fitted around the perimeter of the hull, energized by the ship's electrical system whenever in suspected magnetic-mined waters. Some of the first to be so fitted were the <a href="/wiki/Aircraft_carrier" title="Aircraft carrier">carrier</a> <a href="/wiki/HMS_Ark_Royal_(91)" title="HMS Ark Royal (91)">HMS Ark Royal</a> and the liners <a href="/wiki/RMS_Queen_Mary" title="RMS Queen Mary">RMS Queen Mary</a> and <a href="/wiki/RMS_Queen_Elizabeth" title="RMS Queen Elizabeth">RMS Queen Elizabeth</a>. It was a photo of one of these liners in New York harbour, showing the degaussing coil, which revealed to German Naval Intelligence the fact that the British were using degaussing methods to combat their magnetic mines.<a href="#cite_note-33">[33]</a> This was felt to be impractical for smaller warships and merchant vessels, mainly because the ships lacked the generating capacity to energise such a coil. It was found that "wiping" a current-carrying cable up and down a ship's hull<a href="#cite_note-34">[34]</a> temporarily canceled the ships' magnetic signature sufficiently to nullify the threat. This started in late 1939, and by 1940 merchant vessels and the smaller British warships were largely immune for a few months at a time until they once again built up a field. The cruiser <a href="/wiki/HMS_Belfast" title="HMS Belfast">HMS Belfast</a> is just one example of a ship that was struck by a magnetic mine during this time. On 21 November 1939, a mine broke her keel, which damaged her engine and boiler rooms, as well as injuring 46 men, one later died from his injuries. She was towed to <a href="/wiki/Rosyth_Dockyard" title="Rosyth Dockyard">Rosyth</a> for repairs.

They are still used today, as they are extremely low cost compared to any other anti-ship weapon and are effective, both as a psychological weapon and as a method to sink enemy ships. Contact mines need to be touched by the target before they detonate, limiting the damage to the direct effects of the explosion and usually affecting only the vessel that triggers them. Early mines had mechanical mechanisms to detonate them, but these were superseded in the 1870s by the "Hertz horn" (or "chemical horn"), which was found to work reliably even after the mine had been in the sea for several years. The mine's upper half is studded with hollow lead protuberances, each containing a glass vial filled with <a href="/wiki/Sulfuric_acid" title="Sulfuric acid">sulfuric acid</a>. When a ship's hull crushes the metal horn, it cracks the vial inside it, allowing the acid to run down a tube and into a <a href="/wiki/Lead%E2%80%93acid_battery" title="Lead–acid battery">lead–acid battery</a> which until then contained no acid electrolyte. This energizes the battery, which detonates the explosive.<a href="#cite_note-hartshorn.us-50">[50]</a> Earlier forms of the detonator employed a vial of sulfuric acid surrounded by a mixture of <a href="/wiki/Potassium_perchlorate" title="Potassium perchlorate">potassium perchlorate</a> and sugar. When the vial was crushed, the acid ignited the perchlorate-sugar mix, and the resulting flame ignited the gunpowder charge.<a href="#cite_note-51">[51]</a> During the initial period of World War I, the Royal Navy used contact mines in the English Channel and later in large areas of the North Sea to hinder patrols by German submarines. Later, the American antenna mine was widely used because submarines could be at any depth from the surface to the seabed. This type of mine had a copper wire attached to a buoy that floated above the explosive charge which was weighted to the seabed with a steel cable.

A steel cable connecting the mine to an anchor on the seabed prevents it from drifting away. The explosive and detonating mechanism is contained in a buoyant metal or plastic shell. The depth below the surface at which the mine floats can be set so that only deep draft vessels such as aircraft carriers, battleships or large cargo ships are at risk, saving the mine from being used on a less valuable target. In <a href="/wiki/Littoral" class="mw-redirect" title="Littoral">littoral</a> waters it is important to ensure that the mine does not become visible when the sea level falls at low tide, so the cable length is adjusted to take account of tides. During WWII there were mines that could be moored in 300 m (980 ft)-deep water. Floating mines typically have a mass of around 200 kg (440 lb), including 80 kg (180 lb) of explosives e.g. <a href="/wiki/Trinitrotoluene" class="mw-redirect" title="Trinitrotoluene">TNT</a>, <a href="/wiki/Minol_(explosive)" title="Minol (explosive)">minol</a> or <a href="/wiki/Amatol" title="Amatol">amatol</a>.<a href="#cite_note-52">[52]</a> <div class="mw-heading mw-heading5"><h5 id="Moored_contact_mines_with_plummet">Moored contact mines with plummet</h5>[<a href="/w/index.php?title=Naval_mine&action=edit&section=13" title="Edit section: Moored contact mines with plummet">edit</a>]</div> <figure class="mw-default-size" typeof="mw:File/Thumb"><a href="/wiki/File:Legen_einer_Ankertaumine.svg" class="mw-file-description"><img src="//upload.wikimedia.org/wikipedia/commons/thumb/f/f5/Legen_einer_Ankertaumine.svg/220px-Legen_einer_Ankertaumine.svg.png" decoding="async" width="220" height="172" class="mw-file-element" srcset="//upload.wikimedia.org/wikipedia/commons/thumb/f/f5/Legen_einer_Ankertaumine.svg/330px-Legen_einer_Ankertaumine.svg.png 1.5x, //upload.wikimedia.org/wikipedia/commons/thumb/f/f5/Legen_einer_Ankertaumine.svg/440px-Legen_einer_Ankertaumine.svg.png 2x" data-file-width="512" data-file-height="400" /></a><figcaption>Sequence of laying a moored contact mine with a plummet</figcaption></figure> A special form of moored contact mines are those equipped with a plummet. When the mine is launched (1), the mine with the anchor floats first and the lead plummet sinks from it (2). In doing so, the plummet unwinds a wire, the deep line, which is used to set the depth of the mine below the water surface before it is launched (3). When the deep line has been unwound to a set length, the anchor is flooded and the mine is released from the anchor (4). The anchor begins to sink and the mooring cable unwinds until the plummet reaches the sea floor (5). Triggered by the decreasing tension on the deep line, the mooring cable is clamped. The anchor continues sinking down to the bottom of the sea, pulling the mine below the water surface to a depth equal to the length of the deep line (6). Thus, even without knowing the exact seafloor depth, an exact depth of the mine below the water surface can be set, limited only by the maximum length of the mooring cable. <div class="mw-heading mw-heading4"><h4 id="Drifting_contact_mines">Drifting contact mines</h4>[<a href="/w/index.php?title=Naval_mine&action=edit&section=14" title="Edit section: Drifting contact mines">edit</a>]</div> Drifting mines were occasionally used during World War I and World War II. However, they were more feared than effective. Sometimes floating mines break from their moorings and become drifting mines; modern mines are designed to deactivate in this event. After several years at sea, the deactivation mechanism might not function as intended and the mines may remain live. <a href="/wiki/John_Jellicoe,_1st_Earl_Jellicoe" title="John Jellicoe, 1st Earl Jellicoe">Admiral Jellicoe</a>'s British fleet did not pursue and destroy the outnumbered German High Seas Fleet when it turned away at the <a href="/wiki/Battle_of_Jutland" title="Battle of Jutland">Battle of Jutland</a> because he thought they were leading him into a trap: he believed it possible that the Germans were either leaving floating mines in their wake, or were drawing him towards submarines, although neither of these was the case. After World War I the drifting contact mine was banned, but was occasionally used during World War II. The drifting mines were much harder to remove than tethered mines after the war, and they caused about the same damage to both sides.<a href="#cite_note-53">[53]</a> Churchill promoted "<a href="/wiki/Operation_Royal_Marine" title="Operation Royal Marine">Operation Royal Marine</a>" in 1940 and again in 1944 where floating mines were put into the <a href="/wiki/Rhine" title="Rhine">Rhine</a> in France to float down the river, becoming active after a time calculated to be long enough to reach German territory. <div class="mw-heading mw-heading3"><h3 id="Remotely_controlled_mines">Remotely controlled mines</h3>[<a href="/w/index.php?title=Naval_mine&action=edit&section=15" title="Edit section: Remotely controlled mines">edit</a>]</div> Frequently used in combination with coastal artillery and hydrophones, <a href="/wiki/Controlled_mines" title="Controlled mines">controlled mines</a> (or command detonation mines) can be in place in peacetime, which is a huge advantage in blocking important shipping routes.

Such mines incorporate sensors designed to detect the presence of a vessel and <a href="/wiki/Detonation" title="Detonation">detonate</a> when it comes within the <a href="/wiki/Explosion" title="Explosion">blast</a> range of the <a href="/wiki/Warhead" title="Warhead">warhead</a>. The fuzes on such mines may incorporate one or more of the following sensors: <a href="/wiki/Magnetic" class="mw-redirect" title="Magnetic">magnetic</a>, passive <a href="/wiki/Acoustic_signature" title="Acoustic signature">acoustic</a> or water <a href="/wiki/Pressure" title="Pressure">pressure</a> displacement caused by the proximity of a vessel.<a href="#cite_note-56">[56]</a> First used during WWI, their use became more general in WWII. The sophistication of influence mine fuzes has increased considerably over the years as first <a href="/wiki/Transistor" title="Transistor">transistors</a> and then <a href="/wiki/Microprocessor" title="Microprocessor">microprocessors</a> have been incorporated into designs. Simple magnetic sensors have been superseded by total-field <a href="/wiki/Magnetometer" title="Magnetometer">magnetometers</a>. Whereas early magnetic mine fuzes would respond only to changes in a single component of a target vessel's magnetic field, a total field magnetometer responds to changes in the magnitude of the total background field (thus enabling it to better detect even degaussed ships). Similarly, the original broadband <a href="/wiki/Hydrophone" title="Hydrophone">hydrophones</a> of 1940s acoustic mines (which operate on the integrated volume of all frequencies) have been replaced by narrow-band sensors which are much more sensitive and selective. Mines can now be programmed to listen for highly specific <a href="/wiki/Acoustic_signature" title="Acoustic signature">acoustic signatures</a> (e.g. a <a href="/wiki/Gas_turbine" title="Gas turbine">gas turbine</a> powerplant or <a href="/wiki/Cavitation" title="Cavitation">cavitation</a> sounds from a particular design of <a href="/wiki/Screw_propeller" class="mw-redirect" title="Screw propeller">propeller</a>) and ignore all others. The sophistication of modern electronic mine fuzes incorporating these <a href="/wiki/Digital_signal_processing" title="Digital signal processing">digital signal processing</a> capabilities makes it much more difficult to detonate the mine with <a href="/wiki/Electronic_countermeasures" class="mw-redirect" title="Electronic countermeasures">electronic countermeasures</a> because several sensors working together (e.g. magnetic, passive acoustic and water pressure) allow it to ignore signals which are not recognised as being the unique signature of an intended target vessel.<a href="#cite_note-fas.org-57">[57]</a> Modern influence mines such as the <a href="/wiki/Stonefish_(mine)" title="Stonefish (mine)">BAE Stonefish</a> are <a href="/wiki/Embedded_computer_system" class="mw-redirect" title="Embedded computer system">computerised</a>, with all the programmability this implies, such as the ability to quickly load new <a href="/wiki/Acoustic_signature" title="Acoustic signature">acoustic signatures</a> into fuzes, or program them to detect a single, highly distinctive target signature. In this way, a mine with a passive acoustic fuze can be programmed to ignore all friendly vessels and small enemy vessels, only detonating when a very large enemy target passes over it. Alternatively, the mine can be programmed specifically to ignore all surface vessels regardless of size and exclusively target submarines. Even as far back as WWII it was possible to incorporate a "ship counter" function in mine fuzes. This might set the mine to ignore the first two ships passing over it (which could be minesweepers deliberately trying to trigger mines) but detonate when the third ship passes overhead, which could be a high-value target such as an <a href="/wiki/Aircraft_carrier" title="Aircraft carrier">aircraft carrier</a> or <a href="/wiki/Oil_tanker" title="Oil tanker">oil tanker</a>. Even though modern mines are generally powered by a long life <a href="/wiki/Lithium_metal_battery" title="Lithium metal battery">lithium battery</a>, it is important to conserve power because they may need to remain active for months or even years. For this reason, most influence mines are designed to remain in a semi-dormant state until an unpowered (e.g. deflection of a <a href="/wiki/Mu-metal" title="Mu-metal">mu-metal</a> <a href="/wiki/Magnetic_compass" class="mw-redirect" title="Magnetic compass">needle</a>) or low-powered sensor detects the possible presence of a vessel, at which point the mine fuze powers up fully and the passive acoustic sensors will begin to operate for some minutes. It is possible to program computerised mines to delay activation for days or weeks after being laid. Similarly, they can be programmed to <a href="/wiki/Self-destruct" title="Self-destruct">self-destruct</a> or render themselves safe after a preset period of time. Generally, the more sophisticated the mine design, the more likely it is to have some form of <a href="/wiki/Anti-handling_device" title="Anti-handling device">anti-handling device</a> to hinder clearance by divers or remotely piloted submersibles.<a href="#cite_note-fas.org-57">[57]</a><a href="#cite_note-ReferenceA-58">[58]</a> <div class="mw-heading mw-heading4"><h4 id="Moored_mines">Moored mines</h4>[<a href="/w/index.php?title=Naval_mine&action=edit&section=17" title="Edit section: Moored mines">edit</a>]</div> The moored mine is the backbone of modern mine systems. They are deployed where water is too deep for bottom mines. They can use several kinds of instruments to detect an enemy, usually a combination of acoustic, magnetic and pressure sensors, or more sophisticated optical shadows or electro potential sensors. These cost many times more than contact mines. Moored mines are effective against most kinds of ships. As they are cheaper than other anti-ship weapons they can be deployed in large numbers, making them useful <a href="/wiki/Area_denial" class="mw-redirect" title="Area denial">area denial</a> or "channelizing" weapons. Moored mines usually have lifetimes of more than 10 years, and some almost unlimited. These mines usually weigh 200 kg (440 lb), including 80 kg (180 lb) of explosives (<a href="/wiki/RDX" title="RDX">RDX</a>). In excess of 150 kg (330 lb) of explosives the mine becomes inefficient, as it becomes too large to handle and the extra explosives add little to the mine's effectiveness.[<a href="/wiki/Wikipedia:Citation_needed" title="Wikipedia:Citation needed">citation needed</a>] <div class="mw-heading mw-heading4"><h4 id="Bottom_mines">Bottom mines</h4>[<a href="/w/index.php?title=Naval_mine&action=edit&section=18" title="Edit section: Bottom mines">edit</a>]</div> Bottom mines (sometimes called ground mines) are used when the water is no more than 60 meters (200 feet) deep or when mining for submarines down to around 200 meters (660 feet).

During WWI and WWII, the Germans used <a href="/wiki/U-boat" title="U-boat">U-boats</a> to lay mines around the UK. In WWII, aircraft came into favour for mine laying with one of the largest examples being the mining of the Japanese sea routes in <a href="/wiki/Operation_Starvation" title="Operation Starvation">Operation Starvation</a>. Laying a minefield is a relatively fast process with specialized ships, which is today the most common method. These minelayers can carry several thousand mines[<a href="/wiki/Wikipedia:Citation_needed" title="Wikipedia:Citation needed">citation needed</a>] and manoeuvre with high precision. The mines are dropped at predefined intervals into the water behind the ship. Each mine is recorded for later clearing, but it is not unusual for these records to be lost together with the ships. Therefore, many countries demand that all mining operations be planned on land and records kept so that the mines can later be recovered more easily.<a href="#cite_note-65">[65]</a> Other methods to lay minefields include: <ul><li>Converted merchant ships – rolled or slid down ramps</li> <li>Aircraft – descent to the water is slowed by a parachute</li> <li>Submarines – launched from <a href="/wiki/Torpedo_tubes" class="mw-redirect" title="Torpedo tubes">torpedo tubes</a> or deployed from specialized mine racks on the sides of the submarine</li> <li>Combat boats – rolled off the side of the boat</li> <li>Camouflaged boats – masquerading as fishing boats</li> <li>Dropping from the shore – typically smaller, shallow-water mines</li> <li>Attack divers – smaller shallow-water mines</li></ul> In some cases, mines are automatically activated upon contact with the water. In others, a safety <a href="/wiki/Lanyard" title="Lanyard">lanyard</a> is pulled (one end attached to the rail of a ship, aircraft or torpedo tube) which starts an automatic timer countdown before the arming process is complete. Typically, the automatic safety-arming process takes some minutes to complete.

Admiral <a href="/wiki/Thomas_C._Kinkaid" title="Thomas C. Kinkaid">Thomas C.

Advancing military forces worked to clear mines from newly-taken areas, but extensive minefields remained in place after the war. Air-dropped mines had an additional problem for mine sweeping operations: they were not meticulously charted. In Japan, much of the B-29 mine-laying work had been performed at high altitude, with the drifting on the wind of mines carried by parachute adding a randomizing factor to their placement. Generalized danger areas were identified, with only the quantity of mines given in detail. Mines used in <a href="/wiki/Operation_Starvation" title="Operation Starvation">Operation Starvation</a> were supposed to be self-sterilizing, but the circuit did not always work.

The explosion creates a bubble in the water, and due to the difference in pressure, the bubble will collapse from the bottom. The bubble is buoyant, and so it rises towards the surface. If the bubble reaches the surface as it collapses, it can create a pillar of water that can go over a hundred meters into the air (a "columnar plume"). If conditions are right and the bubble collapses onto the ship's hull, the damage to the ship can be extremely serious; the collapsing bubble forms a high-energy jet similar to a <a href="/wiki/Shaped_charge" title="Shaped charge">shaped charge</a> that can break a metre-wide hole straight through the ship, flooding one or more compartments, and is capable of breaking smaller ships apart.

This is especially true for minesweepers and mine hunters that work in minefields, where a minimal signature outweighs the need for armour and speed.

These ships may use special propulsion systems, with <a href="/wiki/Low_magnetic_electric_motor" title="Low magnetic electric motor">low magnetic electric motors</a>, to reduce magnetic signature, and <a href="/wiki/Voith-Schneider" class="mw-redirect" title="Voith-Schneider">Voith-Schneider</a> propellers, to limit the <a href="/wiki/Acoustic_signature" title="Acoustic signature">acoustic signature</a>.

(See also <a href="/wiki/SQQ-32_Mine-hunting_sonar" class="mw-redirect" title="SQQ-32 Mine-hunting sonar">SQQ-32 Mine-hunting sonar</a>) A steel-hulled ship can be <a href="/wiki/Degaussing" title="Degaussing">degaussed</a> (more correctly, de-oerstedted or <a href="/wiki/Deperming" class="mw-redirect" title="Deperming">depermed</a>) using a special degaussing station that contains many large coils and induces a magnetic field in the hull with alternating current to demagnetize the hull. This is a rather problematic solution, as magnetic compasses need recalibration and all metal objects must be kept in exactly the same place. Ships slowly regain their magnetic field as they travel through the Earth's magnetic field, so the process has to be repeated every six months.<a href="#cite_note-90">[90]</a> A simpler variation of this technique called wiping, was developed by <a href="/wiki/Charles_F._Goodeve" title="Charles F. Goodeve">Charles F. Goodeve</a> which saved time and resources. Between 1941 and 1943 the US Naval Gun factory (a division of the Naval Ordnance Laboratory) in Washington, D.C., built physical models of all US naval ships. Three kinds of steel were used in shipbuilding: mild steel for bulkheads, a mixture of mild steel and high tensile steel for the hull, and <a href="/wiki/Special_treatment_steel" title="Special treatment steel">special treatment steel</a> for armor plate. The models were placed within coils which could simulate the Earth's magnetic field at any location. The magnetic signatures were measured with degaussing coils. The objective was to reduce the vertical component of the combination of the Earth's field and the ship's field at the usual depth of German mines. From the measurements, coils were placed and coil currents were determined to minimize the chance of detonation for any ship at any heading at any latitude.<a href="#cite_note-eaglespeak.us-91">[91]</a> Some ships are built with magnetic <a href="/wiki/Inductor" title="Inductor">inductors</a>, large coils placed along the ship to counter the ship's magnetic field. Using magnetic probes in strategic parts of the ship, the strength of the current in the coils can be adjusted to minimize the total magnetic field. This is a heavy and clumsy solution, suited only to small-to-medium-sized ships. Boats typically lack the generators and space for the solution, while the amount of power needed to overcome the magnetic field of a large ship is impractical.<a href="#cite_note-eaglespeak.us-91">[91]</a> <div class="mw-heading mw-heading3"><h3 id="Active_countermeasures">Active countermeasures</h3>[<a href="/w/index.php?title=Naval_mine&action=edit&section=44" title="Edit section: Active countermeasures">edit</a>]</div> Active countermeasures are ways to clear a path through a minefield or remove it completely.

The sweeps are dragged by <a href="/wiki/Minesweeper_(ship)" class="mw-redirect" title="Minesweeper (ship)">minesweepers</a>, either purpose-built military ships or converted <a href="/wiki/Commercial_trawler" class="mw-redirect" title="Commercial trawler">trawlers</a>. Each run covers between one hundred and two hundred metres (330 and 660 ft), and the ships must move slowly in a straight line, making them vulnerable to enemy fire. This was exploited by the Turkish army in the <a href="/wiki/Battle_of_Gallipoli" class="mw-redirect" title="Battle of Gallipoli">Battle of Gallipoli</a> in 1915, when mobile <a href="/wiki/Howitzer" title="Howitzer">howitzer</a> batteries prevented the British and French from clearing a way through minefields. If a contact sweep hits a mine, the wire of the sweep rubs against the mooring wire until it is cut. Sometimes "cutters", explosive devices to cut the mine's wire, are used to lessen the strain on the sweeping wire. Mines cut free are recorded and collected for research or shot with a deck gun.<a href="#cite_note-92">[92]</a> Minesweepers protect themselves with an <a href="/wiki/Oropesa_(minesweeping)" title="Oropesa (minesweeping)">oropesa</a> or <a href="/wiki/Paravane_(weapon)" class="mw-redirect" title="Paravane (weapon)">paravane</a> instead of a second minesweeper. These are torpedo-shaped towed bodies, similar in shape to a <a href="/wiki/Harvey_torpedo" class="mw-redirect" title="Harvey torpedo">Harvey torpedo</a>, that are streamed from the sweeping vessel thus keeping the sweep at a determined depth and position. Some large warships were routinely equipped with paravane sweeps near the bows in case they inadvertently sailed into minefields—the mine would be deflected towards the paravane by the wire instead of towards the ship by its wake. More recently, heavy-lift helicopters have dragged minesweeping sleds, as in the 1991 Persian Gulf War.<a href="#cite_note-93">[93]</a> The distance sweep mimics the sound and magnetism of a ship and is pulled behind the sweeper. It has floating coils and large underwater drums. It is the only sweep effective against bottom mines. During WWII, <a href="/wiki/RAF_Coastal_Command" title="RAF Coastal Command">RAF Coastal Command</a> used <a href="/wiki/Vickers_Wellington" title="Vickers Wellington">Vickers Wellington</a> bombers Wellington DW.Mk I fitted with degaussing coils to trigger magnetic mines.<a href="#cite_note-94">[94]</a> In a parallel development the Luftwaffe adapted some Junkers 52/3m aircraft to also carry a coil operated by electricity supplied from an onboard generator. The Luftwaffe called this adaption Minensuch(e) (lit. mine-search).<a href="#cite_note-FOOTNOTESmith196616-95">[95]</a> In both cases pilots were required to fly at low altitude (up to about 200 feet above the sea) and at fairly low speeds to be effective. Modern influence mines are designed to discriminate against false inputs and are, therefore, much harder to sweep. They often contain inherent anti-sweeping mechanisms. For example, they may be programmed to respond to the unique noise of a particular ship-type, its associated magnetic signature and the typical pressure displacement of such a vessel. As a result, a mine-sweeper must accurately mimic the required target signature to trigger detonation. The task is complicated by the fact that an influence mine may have one or more of a hundred different potential target signatures programmed into it.<a href="#cite_note-ReferenceB-96">[96]</a> Another anti-sweeping mechanism is a ship-counter in the mine fuze. When enabled, this allows detonation only after the mine <a href="/wiki/Fuze" title="Fuze">fuze</a> has been triggered a pre-set number of times. To further complicate matters, influence mines may be programmed to arm themselves (or disarm automatically—known as self-sterilization) after a pre-set time. During the pre-set arming delay (which could last days or even weeks) the mine would remain dormant and ignore any target stimulus, whether genuine or false.<a href="#cite_note-ReferenceB-96">[96]</a> When influence mines are laid in an ocean minefield, they may have various combinations of fuze settings configured. For example, some mines (with the acoustic sensor enabled) may become active within three hours of being laid, others (with the acoustic and magnetic sensors enabled) may become active after two weeks but have the ship-counter mechanism set to ignore the first two trigger events, and still others in the same minefield (with the magnetic and pressure sensors enabled) may not become armed until three weeks have passed. Groups of mines within this mine-field may have different target signatures which may or may not overlap. The fuzes on influence mines allow many different permutations, which complicates the clearance process.<a href="#cite_note-ReferenceB-96">[96]</a> Mines with ship-counters, arming delays and highly specific target signatures in mine fuzes can falsely convince a belligerent that a particular area is clear of mines or has been swept effectively because a succession of vessels have already passed through safely. <div class="mw-heading mw-heading4"><h4 id="Minehunting">Minehunting</h4>[<a href="/w/index.php?title=Naval_mine&action=edit&section=46" title="Edit section: Minehunting">edit</a>]</div> <figure class="mw-default-size" typeof="mw:File/Thumb"><a href="/wiki/File:Minenjagddrohne_Pinguin.jpg" class="mw-file-description"><img src="//upload.wikimedia.org/wikipedia/commons/thumb/1/10/Minenjagddrohne_Pinguin.jpg/220px-Minenjagddrohne_Pinguin.jpg" decoding="async" width="220" height="165" class="mw-file-element" srcset="//upload.wikimedia.org/wikipedia/commons/thumb/1/10/Minenjagddrohne_Pinguin.jpg/330px-Minenjagddrohne_Pinguin.jpg 1.5x, //upload.wikimedia.org/wikipedia/commons/thumb/1/10/Minenjagddrohne_Pinguin.jpg/440px-Minenjagddrohne_Pinguin.jpg 2x" data-file-width="1280" data-file-height="960" /></a><figcaption>Pinguin B3 minehunting drone, such are operated from <a href="/wiki/Frankenthal-class_minehunter" title="Frankenthal-class minehunter">Frankenthal-class minehunters</a> of the <a href="/wiki/German_Navy" title="German Navy">German Navy</a></figcaption></figure> As naval mines have become more sophisticated, and able to discriminate between targets, so they have become more difficult to deal with by conventional sweeping. This has given rise to the practice of minehunting. Minehunting is very different from sweeping, although some <a href="/wiki/Minehunter" title="Minehunter">minehunters</a> can do both tasks. Minehunting pays little attention to the nature of the mine itself. Nor does the method change much. At the current state of the art, minehunting remains the best way to deal with influence mines proving to be both safer and more effective than sweeping. Specialized high-frequency sonars and high fidelity sidescaning sonar are used for mine location.<a href="#cite_note-minewar-89">[89]</a>: 18  Mines are hunted using sonar, then inspected and destroyed either by divers or <a href="/wiki/Remotely_operated_underwater_vehicle" title="Remotely operated underwater vehicle">ROVs</a> (remote controlled unmanned mini-submarines). It is slow, but also the most reliable way to remove mines. Minehunting started during the Second World War, but it was only after the war that it became truly effective. Sea mammals (mainly the <a href="/wiki/Bottlenose_dolphin" title="Bottlenose dolphin">bottlenose dolphin</a>) have been trained to hunt and mark mines, most famously by the <a href="/wiki/U.S._Navy_Marine_Mammal_Program" class="mw-redirect" title="U.S. Navy Marine Mammal Program">U.S. Navy Marine Mammal Program</a>. Mine-clearance dolphins were deployed in the <a href="/wiki/Persian_Gulf" title="Persian Gulf">Persian Gulf</a> during the <a href="/wiki/Iraq_War" title="Iraq War">Iraq War</a> in 2003. The US Navy claims that these dolphins were effective in helping to clear more than 100 antiship mines and underwater <a href="/wiki/Booby_trap" title="Booby trap">booby traps</a> from <a href="/wiki/Umm_Qasr_Port" title="Umm Qasr Port">Umm Qasr Port</a>.<a href="#cite_note-97">[97]</a> French naval officer <a href="/wiki/Jacques_Yves_Cousteau" class="mw-redirect" title="Jacques Yves Cousteau">Jacques Yves Cousteau</a>'s Undersea Research Group was once involved in minehunting operations: They removed or detonated a variety of German mines, but one particularly defusion-resistant batch—equipped with acutely sensitive pressure, magnetic, and acoustic sensors and wired together so that one explosion would trigger the rest—was simply left undisturbed for years until corrosion would (hopefully) disable the mines.<a href="#cite_note-98">[98]</a> <div style="clear:both;" class=""></div> <div class="mw-heading mw-heading4"><h4 id="Mine_running">Mine running</h4>[<a href="/w/index.php?title=Naval_mine&action=edit&section=47" title="Edit section: Mine running">edit</a>]</div> <figure class="mw-default-size" typeof="mw:File/Thumb"><a href="/wiki/File:SeehundeTroika.jpg" class="mw-file-description"><img src="//upload.wikimedia.org/wikipedia/commons/thumb/a/a6/SeehundeTroika.jpg/220px-SeehundeTroika.jpg" decoding="async" width="220" height="165" class="mw-file-element" srcset="//upload.wikimedia.org/wikipedia/commons/thumb/a/a6/SeehundeTroika.jpg/330px-SeehundeTroika.jpg 1.5x, //upload.wikimedia.org/wikipedia/commons/thumb/a/a6/SeehundeTroika.jpg/440px-SeehundeTroika.jpg 2x" data-file-width="2592" data-file-height="1944" /></a><figcaption><a href="/wiki/Ensdorf_class_minesweeper" class="mw-redirect" title="Ensdorf class minesweeper">Seehund</a> ROVs of the <a href="/wiki/German_Navy" title="German Navy">German Navy</a> used for minesweeping</figcaption></figure> A more drastic method is simply to run a ship through the minefield, letting other ships safely follow the same path. An early example of this was <a href="/wiki/David_Farragut" title="David Farragut">Farragut</a>'s <a href="/wiki/Battle_of_Mobile_Bay" title="Battle of Mobile Bay">actions at Mobile Bay</a> during the <a href="/wiki/American_Civil_War" title="American Civil War">American Civil War</a>. However, as mine warfare became more developed this method became uneconomical. This method was revived by the German <a href="/wiki/Imperial_German_Navy" title="Imperial German Navy">Imperial German Navy</a> during <a href="/wiki/World_War_I" title="World War I">World War I</a>. Left with a surfeit of idle ships due to the <a href="/wiki/Blockade_of_Germany_(1914%E2%80%931919)" title="Blockade of Germany (1914–1919)">Allied blockade</a>, the Germans introduced a ship known as <a href="/wiki/Sperrbrecher" title="Sperrbrecher">Sperrbrecher</a> ("block breaker"). The type was also used during <a href="/wiki/World_War_II" title="World War II">World War II</a>. Typically an old cargo ship, loaded with cargo that made her less vulnerable to sinking (wood for example), the Sperrbrecher was run ahead of the ship to be protected, detonating any mines that might be in their path. The use of Sperrbrecher obviated the need to continuous and painstaking sweeping, but the cost was high. Over half the 100 or so ships used as Sperrbrecher in WWII were sunk during the war. Alternatively, a shallow draught vessel can be steamed through the minefield at high speed to generate a pressure wave sufficient to trigger mines, with the minesweeper moving fast enough to be sufficiently clear of the pressure wave so that triggered mines do not destroy the ship itself. These techniques are the only way to sweep pressure mines that is publicly known to be employed. The technique can be simply countered by use of a ship-counter, set to allow a certain number of passes before the mine is actually triggered. Modern doctrine calls for ground mines to be hunted rather than swept. A new system is being introduced for sweeping pressure mines, however counters are going to remain a problem.<a href="#cite_note-99">[99]</a><a href="#cite_note-100">[100]</a> An updated form of this method is the use of small unmanned <a href="/wiki/Remotely_operated_vehicle" class="mw-redirect" title="Remotely operated vehicle">ROVs</a> (such as the <a href="/wiki/Ensdorf_class_minesweeper" class="mw-redirect" title="Ensdorf class minesweeper">Seehund</a> drone) that simulate the acoustic and magnetic signatures of larger ships and are built to survive exploding mines. Repeated sweeps would be required in case one or more of the mines had its "ship counter" facility enabled i.e. were programmed to ignore the first 2, 3, or even 6 target activations. <div class="mw-heading mw-heading4"><h4 id="Counter-mining">Counter-mining</h4>[<a href="/w/index.php?title=Naval_mine&action=edit&section=48" title="Edit section: Counter-mining">edit</a>]</div> Another expedient for clearing mines, especially in a hurry, is counter-mining. By this method an explosive is detonated in the area of a known or suspected minefield and the blast either trips off the fuzes or the actual explosive contained within the mine or mines. This latter is known as a <a href="/wiki/Sympathetic_detonation" title="Sympathetic detonation">sympathetic detonation</a>. Counter-mining is normally used as a last resort or if other equipment is not available. One example was at the entrance to <a href="/wiki/Grand_Harbour" title="Grand Harbour">Grand Harbour</a>, Valletta, Malta in WW2 when the British dropped depth charges into the harbour entrance to detonate suspected mines prior to the arrival of an important convoy. It is especially useful against acoustic or pressure mines due to their activation by sound or increases in water pressure. <div class="mw-heading mw-heading2"><h2 id="National_arsenals">National arsenals</h2>[<a href="/w/index.php?title=Naval_mine&action=edit&section=49" title="Edit section: National arsenals">edit</a>]</div> <div class="mw-heading mw-heading3"><h3 id="US_mines">US mines</h3>[<a href="/w/index.php?title=Naval_mine&action=edit&section=50" title="Edit section: US mines">edit</a>]</div> The <a href="/wiki/United_States_Navy" title="United States Navy">United States Navy</a> MK56 ASW mine (the oldest still in use by the United States) was developed in 1966.
