The explosive harpoon is a type of harpoon which uses an explosive discharge to assist in whaling. In Norway, Japan, and Iceland, the use of these harpoons is commonplace. Norway created and utilises the most technologically advanced grenades in their harpoons.[ citation needed ]
Among many patents for explosive harpoons is Albert Moore's patented hand-dart explosive harpoon. It was invented on March 16, 1844 (U.S. Patent No. 3,490). This was the first handheld explosive harpoon ever invented. [1]
Patented on May 6, 1851, by Charles Burt of Belfast, Maine (U.S Patent No. 8,073), this was the second harpoon of its kind.
'Mounted' is a term for a broad range of explosive harpoons, as this variant can be mounted onto a ship it is generally bigger and more powerful than a hand thrown explosive harpoon. This type of harpoon is spring operated as explosive discharges which are more common in other forms of harpoons have proven to be volatile and delicate in the 'mounted' variant. [2] [3]
Hand thrown harpoons have been developed over time and now incorporate a gun or a ballistic type firing system. [4]
The explosive harpoon has historically only been used for whaling. Due to Oliver Allen’s improvements to the device, it can now be used on a smaller scale and in common practices like spearfishing. [5] [ failed verification ]
A machine gun is a fully automatic, rifled autoloading firearm designed for sustained direct fire with rifle cartridges. Other automatic firearms such as automatic shotguns and automatic rifles are typically designed more for firing short bursts rather than continuous firepower, and are not considered true machine guns. Submachine guns fire handgun cartridges rather than rifle cartridges and thus are not considered machine guns, while automatic firearms of 20 mm (0.79 in) caliber or more are classified as autocannons rather than machine guns.
A detonator, frequently a blasting cap, is a small sensitive device used to detonate a larger, more powerful but relatively insensitive secondary explosive of an explosive device used in commercial mining, excavation, demolition, etc.
A harpoon is a long spear-like instrument and tool used in fishing, whaling, sealing, and other marine hunting to catch and injure large fish or marine mammals such as seals and whales. It accomplishes this task by impaling the target animal and securing it with barb or toggling claws, allowing the fishermen to use a rope or chain attached to the projectile to catch the animal. A harpoon can also be used as a weapon. Certain harpoons are made with different builds to perform better with the type of target being aimed at. For example, the Inuit have short, fixed foreshaft harpoons for hunting seals at their breathing holes while loose shafted ones are made for attaching to the game thrown at.
"Mills bomb" is the popular name for a series of British hand grenades which were designed by William Mills. They were the first modern fragmentation grenades used by the British Army and saw widespread use in the First and Second World Wars.
This article discusses the history of whaling from prehistoric times up to the commencement of the International Whaling Commission (IWC) moratorium on commercial whaling in 1986. Whaling has been an important subsistence and economic activity in multiple regions throughout human history. Commercial whaling dramatically reduced in importance during the 19th century due to the development of alternatives to whale oil for lighting, and the collapse in whale populations. Nevertheless, some nations continue to hunt whales even today.
A ranged weapon is any weapon that can engage targets beyond hand-to-hand distance, i.e. at distances greater than the physical reach of the user holding the weapon itself. The act of using such a weapon is also known as shooting. It is sometimes also called projectile weapon or missile weapon because it typically works by launching solid projectiles ("missiles"), though technically a fluid-projector and a directed-energy weapon are also ranged weapons. In contrast, a weapon intended to be used in hand-to-hand combat is called a melee weapon.
The MG FF was a drum-fed, blowback-operated, 20 mm aircraft autocannon, developed in 1936 by Ikaria Werke Berlin of Germany. It was a derivative of the Swiss Oerlikon FF F cannon, with the Oerlikon FF design itself a development of the Imperial German World War I Becker 20 mm cannon, and was designed to be used in space-limited, fixed mountings such as inside aircraft wings, although it saw use as both an offensive and a defensive weapon, in both fixed and flexible format. It saw widespread use in those roles by the German Luftwaffe, particularly during the early stages of World War II, although from 1941 onwards it was gradually replaced by the Mauser firm's 20 mm MG 151/20, which was lighter, and had both a higher rate of fire and muzzle velocity.
A volley gun is a gun with multiple single-shot barrels that shoot projectiles in volley fire, either simultaneously or in succession. Although capable of unleashing intense firepower, volley guns differ from modern machine guns in that they lack autoloading and automatic fire mechanisms, and therefore their volume of fire is limited by the number of barrels bundled together.
The term swivel gun usually refers to a small cannon, mounted on a swiveling stand or fork which allows a very wide arc of movement. Another type of firearm referred to as a swivel gun was an early flintlock combination gun with two barrels that rotated along their axes to allow the shooter to switch between rifled and smoothbore barrels.
The Type 96 25 mm gun was an automatic cannon used by the Imperial Japanese Navy during World War II. A locally-built variant of the French Hotchkiss 25 mm anti-aircraft gun, it was designed as a dual-purpose weapon for use against armored vehicles and aircraft, but was primarily used as an anti-aircraft gun in fixed mounts with one to three guns.
Svend Foyn was a Norwegian whaling, shipping magnate and philanthropist. He pioneered revolutionary methods for hunting and processing whales. Svend Foyn introduced the modern harpoon cannon and brought whaling into a modern age. He is also recognized as a pioneer who introduced sealing to Vestfold County.
Erik Eriksen was a Norwegian polar captain. Eriksen was the first to sight and shore Kong Karls Land, commemorated by the strait Erik Eriksenstretet. Eriksen also contributed to the invention of the grenade harpoon used in modern whaling.
A whaler or whaling ship is a specialized vessel, designed or adapted for whaling: the catching or processing of whales.
Whaling in Iceland began with spear-drift hunting as early as the 12th century, and continued in a vestigial form until the late 19th century, when other countries introduced modern commercial practices. Today, Iceland is one of a handful of countries that formally object to an ongoing moratorium established by the International Whaling Commission in 1986, and that still maintain a whaling fleet. One company remains concentrated on hunting fin whales, largely for export to Japan, while the only other one previously hunted minke whales for domestic consumption until 2020, as the meat was popular with tourists. In 2018, Icelandic whalers were accused of slaughtering a blue whale. Whaling was temporarily paused in Iceland between 2019 and 2021 as coronavirus restrictions, competition from subsidized Japanese whaling, and increasing domestic whale watching tourism have hampered the industry, however the practice is set to resume in 2022. A ban may come about by 2024 due to low demand and profitability. Iceland has a whale watching sector, which exists in tension with the whaling industry.
Whaling in Norway involves hunting of minke whales for use as animal and human food in Norway and for export to Japan. Whale hunting has been a part of Norwegian coastal culture for centuries, and commercial operations targeting the minke whale have occurred since the early 20th century. Some still continue the practice in the modern day, within annual quotas.
The history of cannons spans several hundred years from the 12th century to modern times. The cannon first appeared in China sometime during the 12th and 13th centuries. It was most likely developed in parallel or as an evolution of an earlier gunpowder weapon called the fire lance. The result was a projectile weapon in the shape of a cylinder that fired projectiles using the explosive pressure of gunpowder. Cannons were used for warfare by the late 13th century in the Yuan dynasty and spread throughout Eurasia in the 14th century. During the Middle Ages, large and small cannons were developed for siege and field battles. The cannon replaced prior siege weapons such as the trebuchet. After the Middle Ages, most large cannons were abandoned in favor of greater numbers of lighter, more maneuverable field artillery. New defensive fortifications such as bastions and star forts were designed specifically to better withstand artillery sieges. Cannons transformed naval warfare with its deadly firepower, allowing vessels to destroy each other from long range. As rifling became more commonplace, the accuracy of the cannon was significantly improved, and they became deadlier than ever, especially to infantry. In World War I, a considerable majority of all deaths were caused by cannons; they were also used widely in World War II. Most modern cannons are similar to those used in the Second World War, including autocannons—with the exception of naval guns, which are now significantly smaller in caliber.
A gun is a device or ranged weapon designed to throw a projectile using pressure or explosive force. The projectiles are typically solid, but can also be pressurized liquid, or gas. Solid projectiles may be free-flying or tethered. A large-caliber gun is also called a cannon.
A harpoon cannon is a whaling implement developed in the late 19th century and most used in the 20th century. It would be mounted on the bow of a whale catcher, where it could be easily aimed with a wide field of view at the target. Powered by black powder and later, smokeless powder, it would generally fire a large steel harpoon, either solid steel or fitted with an exploding black powder, or later, penthrite (PETN) grenade.
Petrel was a whaler, built in Oslo, in 1928, in operation in the waters around Antarctica for over three decades.
A repeating firearm or repeater is any firearm that is capable of being fired repeatedly before having to manually reload new ammunition into the weapon.
