Development

During the American Civil War, Matthew Fontaine Maury, a Confederate government official established the Torpedo Bureau and the Torpedo Corps in Richmond, Virginia to oversee the development and deployment of new types of naval mines. [1] Maury was convinced that the only way to defend the coastlines against Union assaults was through the widespread use of naval mines. Mines were inexpensive and easily produced on a large scale. The low cost and large volume of mines produced would supplement the small naval forces of the Confederacy and make it possible to defend against the superior fleet of the Union navy. [2] The efforts of the Torpedo Bureau and the Torpedo Corps proved to be worth the investment of the Confederacy. For the relative low cost of the mines they did a tremendous amount of damage to the Union forces, sinking a total of 27 Union naval vessels. [3]

Features

The most successful naval mine of the Confederacy is known as the ‘Singer’ mine, so-called because it was invented by a member of the family which owned and operated the Singer Corporation. The ‘Singer’ was a manually laid moored contact mine; it was set off when struck by an object with sufficient force to trigger the automatic fuse. The body of the mine was made from sheets of iron and was filled with a charge of 55-65 pounds of gunpowder. [4] The automatic fuse consisted of a heavy metal cap that would be released by the force of a ship impacting it. As the cap was released it triggered a spring mechanism that struck a fulminating charge, in the form of a percussion cap, which detonated the main explosive. [4] It was one of the first mines equipped with a safety mechanism to prevent an accidental explosion. While being handled and during the planting of the mine a safety pin prevented the spring from accidentally triggering the fulminating charge. [2] This pin was removed after the mine was in position. The only major drawback of the ‘Singer’ was that the spring mechanism was exposed to the water. When deployed in salt water sea growth would eventually develop on the spring mechanism, effectively preventing it from striking the fulminating charge within the mine. This flaw in the design caused Confederate minefields, especially in tropical waters, to become inert after a period of time.

Land mine Explosive weapon, concealed under or on the ground

A land mine is an explosive device concealed under or on the ground and designed to destroy or disable enemy targets, ranging from combatants to vehicles and tanks, as they pass over or near it. Such a device is typically detonated automatically by way of pressure when a target steps on it or drives over it, although other detonation mechanisms are also sometimes used. A land mine may cause damage by direct blast effect, by fragments that are thrown by the blast, or by both.

Naval mine Explosive weapon for use in seas and waterways, triggered by the targets approach

A naval mine is a self-contained explosive device placed in water to damage or destroy surface ships or submarines. Unlike depth charges, mines are deposited and left to wait until 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 protect friendly vessels and create "safe" zones. Mines allow the minelaying force commander to concentrate warships or defensive assets in mine-free areas giving the adversary three choices: undertake an expensive 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.

Torpedo boat small and fast naval vessel armed with torpedoes

A torpedo boat is a relatively small and fast naval ship designed to carry torpedoes into battle. The first designs were steam-powered craft dedicated to ramming enemy ships with explosive spar torpedoes. Later evolutions launched variants of self-propelled Whitehead torpedoes.

Detonator system used to trigger explosion of a main charge

A detonator, frequently a blasting cap, is a device used to trigger an explosive device. Detonators can be chemically, mechanically, or electrically initiated, the latter two being the most common.

Percussion cap type of firearm igniter

The percussion cap, introduced circa 1820, is a type of single-use ignition device used on muzzleloader firearms that enabled them to fire reliably in any weather condition. This crucial invention gave rise to the caplock or percussion lock system.

Ironclad warship Steam-propelled warship protected by iron or steel armor plates

An ironclad is a steam-propelled warship protected by iron or steel armor plates used in the early part of the second half of the 19th century. The ironclad was developed as a result of the vulnerability of wooden warships to explosive or incendiary shells. The first ironclad battleship, Gloire, was launched by the French Navy in November 1859. The British Admiralty had been considering armored warships since 1856 and prepared a draft design for an armored corvette in 1857; in early 1859 the Royal Navy started building two iron-hulled armored frigates, and by 1861 had made the decision to move to an all-armored battle fleet. After the first clashes of ironclads took place in 1862 during the American Civil War, it became clear that the ironclad had replaced the unarmored ship of the line as the most powerful warship afloat. This type of ship would come to be very successful in the American Civil War.

Confederate States Navy maritime warfare branch of the Confederate States military

The Navy of the Confederate States (CSN) was the naval branch of the Confederate States Armed Forces, established by an act of the Confederate States Congress on February 21, 1861. It was responsible for Confederate naval operations during the American Civil War (1861–1865), fighting against the Union Navy / United States Navy.

Stephen Mallory American politician

Stephen Russell Mallory was a Democratic senator from Florida from 1850 to the secession of his home state and the outbreak of the American Civil War. For much of that period, he was chairman of the Committee on Naval Affairs. It was a time of rapid naval reform, and he insisted that the ships of the US Navy should be as capable as those of Britain and France, the foremost navies in the world at that time. He also wrote a bill and guided it through Congress to provide for compulsory retirement of officers who did not meet the standards of the profession.

Minelayer vessel for placing naval mines

Minelaying is the act of deploying explosive mines. Historically this has been carried out by ships, submarines and aircraft. Additionally, since World War I the term minelayer refers specifically to a naval ship used for deploying naval mines. "Mine planting" was the term for installing controlled mines at predetermined positions in connection with coastal fortifications or harbor approaches that would be detonated by shore control when a ship was fixed as being within the mine's effective range.

Time bomb bomb whose detonation is triggered by a timer

A time bomb is a bomb whose detonation is triggered by a timer. The use of time bombs has been for various purposes including insurance fraud, terrorism, assassination, sabotage and warfare. They are a popular feature in fictional thriller and action films as they offer a way of imparting a dramatic sense of urgency.

S-mine anti-personnel mine

The German S-mine, also known as the "Bouncing Betty" on the Western Front and "frog-mine" on the Eastern Front, is the best-known version of a class of mines known as bounding mines. When triggered, these mines are launched into the air and then detonated at about 1 meter (3 ft) from the ground. The explosion projects a lethal spray of shrapnel in all directions. The S-mine was an anti-personnel mine developed by Germany in the 1930s and used extensively by German forces during World War II. It was designed to be used in open areas against unshielded infantry. Two versions were produced, designated by the year of their first production: the SMi-35 and SMi-44. There are only minor differences between the two models.

Minesweeping action of removing explosive mines

Minesweeping is the practice of the removal of explosive naval mines, usually by a specially designed ship called a minesweeper using various measures to either capture or detonate the mines, but sometimes also with an aircraft made for that purpose. Minesweeping has been practiced since the advent of naval mining in 1855 in the Crimean War. The first minesweepers date to that war and consisted of British rowboats trailing grapnels to snag the mines.

Spar torpedo

A spar torpedo is a weapon consisting of a bomb placed at the end of a long pole, or spar, and attached to a boat. The weapon is used by running the end of the spar into the enemy ship. Spar torpedoes were often equipped with a barbed spear at the end, so it would stick to wooden hulls. A fuse could then be used to detonate it.

Confederate Secret Service refers to any of a number of official and semi-official secret service organizations and operations conducted by the Confederate States of America during the American Civil War. Some of the organizations were under the direction of the Confederate government, others operated independently with government approval, while still others were either completely independent of the government or operated with only its tacit acknowledgment.

Coal torpedo weapon used for sabotage

The coal torpedo was a hollow iron casting filled with explosives and covered in coal dust, deployed by the Confederate Secret Service during the American Civil War, and intended for doing harm to Union steam transportation. When shoveled into the firebox amongst the coal, the resulting explosion would at the very least damage the boiler and render the engines inoperable. At worst, a catastrophic boiler explosion would kill crewmen and passengers, start a fire, or even sink the vessel.

Anti-handling device integral part of a landmine or other munition that prevents tampering and disarming

An anti-handling device is an attachment to—or an integral part of—a landmine or other munition e.g. some fuze types found in general purpose air-dropped bombs, cluster bombs and sea mines. It is designed to prevent tampering. When the protected device is disturbed, it detonates, killing or injuring anyone within the blast area. There is a strong functional overlap of booby traps and anti-handling devices.

In military munitions, a fuze is the part of the device that initiates function. In some applications, such as torpedoes, a fuze may be identified by function as the exploder. The relative complexity of even the earliest fuze designs can be seen in cutaway diagrams.

An acoustic release is an oceanographic device for the deployment and subsequent recovery of instrumentation from the sea floor, in which the recovery is triggered remotely by an acoustic command signal.

In firearms and artillery, the primer is the chemical and/or device responsible for initiating the propellant combustion that will push the projectiles out of the gun barrel.

Mark 6 exploder

The Mark 6 exploder was a United States Navy torpedo exploder developed in the 1920s. It was the standard exploder of the Navy's Mark 14 torpedo.
