HK P11
The Heckler & Koch P11 is an underwater firearm developed in 1976 by Heckler & Koch. It is loaded using a pepper-box-like assembly, containing five sealed barrels each containing an electrically-fired projectile. Two styles of barrel assembly can be used: one containing five 7.62×36mm flechette darts for use underwater, or five 133-grain bullets for use above water. Design Since ordinary-shaped rounds are inaccurate and have a very short range when used underwater, this pistol fires steel darts underwater or traditional bullets above water. It has five barrels, each of which is loaded with a cartridge, giving the gun a pepper-box appearance, and it is electrically ignited from a battery pack in the pistol grip. Both the underwater dart and above-water bullet barrel assemblies use a sabot to hold the projectile. Each barrel is rifled in two portions: an initial large diameter designed to spin the sabot and projectile, and a second, narrower section to halt the sabot and spin th ...

Underwater Firearm
An underwater firearm is a firearm designed for use underwater. Underwater firearms or needleguns usually fire flechettes or spear-like bolts instead of standard bullets. These may be fired by pressurised gas. History Underwater firearms were first developed in the 1960s during the Cold War as a way to arm combat divers. Design Because standard bullet ammunition does not work well underwater, underwater firearms commonly fire flechettes instead of standard bullets. The barrels of underwater pistols are typically not rifled. Rather, the fired projectile maintains its ballistic trajectory underwater by hydrodynamic effects. The lack of rifling renders these weapons relatively inaccurate when fired out of water. Underwater rifles are more powerful than underwater pistols and more accurate out of water, but underwater pistols can be manipulated more easily underwater. Among the many engineering challenges in designing underwater firearms is that of developing a weapon whi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cold War Weapons Of Germany
Cold is the presence of low temperature, especially in the atmosphere. In common usage, cold is often a subjective perception. A lower bound to temperature is absolute zero, defined as 0.00K on the Kelvin scale, an absolute thermodynamic temperature scale. This corresponds to on the Celsius scale, on the Fahrenheit scale, and on the Rankine scale. Since temperature relates to the thermal energy held by an object or a sample of matter, which is the kinetic energy of the random motion of the particle constituents of matter, an object will have less thermal energy when it is colder and more when it is hotter. If it were possible to cool a system to absolute zero, all motion of the particles in a sample of matter would cease and they would be at complete rest in the classical sense. The object could be described as having zero thermal energy. Microscopically in the description of quantum mechanics, however, matter still has zero-point energy even at absolute zero, because ...

Heckler & Koch Firearms
A heckler is a person who harasses and tries to disconcert others with questions, challenges, or gibes. Hecklers are often known to shout discouraging comments at a performance or event, or to interrupt set-piece speeches, with the intent of disturbing performers or participants. Origin Although the word ''heckler'', which originated from the textile trade, was first attested in the mid-15th century, its use as "person who harasses" is from 1885. To ''heckle'' was to tease or comb out flax or hemp fibres. The additional meaning, to interrupt speakers with awkward or embarrassing questions, was first used in Scotland, and specifically in early 19th century Dundee, a town where the hecklers who combed the flax had established a reputation as the most belligerent element in the workforce. In the heckling factory, one heckler would read out the day's news while the others worked, to the accompaniment of interruptions and furious debate. Heckling was a major part of the vaudeville ...

Underwater Pistols
An underwater environment is a environment of, and immersed in, liquid water in a natural or artificial feature (called a body of water), such as an ocean, sea, lake, pond, reservoir, river, canal, or aquifer. Some characteristics of the underwater environment are universal, but many depend on the local situation. Liquid water has been present on Earth for most of the history of the planet. The underwater environment is thought to be the place of the origin of life on Earth, and it remains the ecological region most critical to the support of life and the natural habitat of the majority of living organisms. Several branches of science are dedicated to the study of this environment or specific parts or aspects of it. A number of human activities are conducted in the more accessible parts of the underwater environment. These include research, underwater diving for work or recreation, and underwater warfare with submarines. It is hostile to humans in many ways and often inaccessi ...

Flechette Firearms
A flechette or flèchette ( ) is a pointed, fin-stabilized steel projectile. The name comes from French (from \'' flèche''), meaning "little arrow" or " dart", and sometimes retains the grave accent in English: flèchette. They have been used as ballistic weapons since World War I. Delivery systems and methods of launching flechettes vary, from a single shot, to thousands in a single explosive round. The use of flechettes as antipersonnel weapons has been controversial; however in war is not prohibited by the Hague Convention. Air-dropped The weapons were designed to be dropped from an aircraft. They contained no explosive charge but as they fell they developed significant kinetic energy making them lethal and able to easily penetrate soft cover such as jungle canopy, several inches of sand or light armor. During World War I, flechettes were dropped from aircraft to attack infantry and were able to pierce helmets. Also during World War II, a version of the flechette with fe ...

Multiple-barrel Firearms
A multiple-barrel firearm is any type of firearm with more than one gun barrel, usually to increase the rate of fire or probability of kill, hit probability and to reduce barrel erosion or overheating. History Volley gun Multiple-barrel firearms date back to the 14th century, when the first primitive volley guns were developed. They are made with several single-shot gun barrel, barrels assembled together for firing a large number of shots, either simultaneously or in quick succession. These firearms were limited in firepower by the number of barrels bundled, and needed to be manually prepared, ignited, and reloaded after each firing. In practice the large volley guns were not particularly more useful than a cannon firing canister shot or grapeshot. Since they were still mounted on a carriage, they could be as hard to aim and move around as a heavy cannon, and the many barrels took as long (if not longer) to reload.Matthew Sharpe "Nock's Volley Gun: A Fearful Discharge" ''A ...

Special Boat Service
The Special Boat Service (SBS) is the special forces unit of the United Kingdom's Royal Navy. The SBS can trace its origins back to the Second World War when the Army Special Boat Section was formed in 1940. After the Second World War, the Royal Navy formed special forces with several name changes—Special Boat Company was adopted in 1951 and re-designated as the Special Boat Squadron in 1974—until on 28 July 1987 when the unit was renamed as the Special Boat Service after assuming responsibility for maritime counter-terrorism. Most of the operations conducted by the SBS are highly classified, and are rarely commented on by the British government or the Ministry of Defence, owing to their sensitive nature. The Special Boat Service is the naval special forces unit of the United Kingdom Special Forces and is described as the sister unit of the British Army 22 Special Air Service Regiment (22 SAS), with both under the operational control of the Director Special Forces.

COMSUBIN
COMSUBIN (''Comando Raggruppamento Subacquei e Incursori "Teseo Tesei"''; Divers and Raiders Group Command "Teseo Tesei") is the Italian Navy's special operations unit. Italy was the first nation to use frogmen and human torpedoes. The Royal Italian Navy's Naval Assault Divisions are considered to be the precursor of modern Naval Special Forces. Their record can be traced back to World War I and the operation against the Austrian-Hungarian Battleship ''Viribus Unitis'' in Pula Harbour in 1918. In World War II, famous operations include Suda Bay, Alexandria, Gibraltar, and Malta. Italy's frogman group originated in 1938 as the ''1a Flottiglia Mezzi d'Assalto'' (1st Flotilla Assault Vehicles), which was reformed in 1940 as the '' Decima Flottiglia MAS'' (10th Flotilla Assault Vehicles, ''10a MAS'').
