Composition H-6
__NOTOC__ Composition H-6 is a melt-cast military aluminized high explosive. H-6 was developed in the US The chemical composition of H-6 is specified as follows: * 45.1 ± 0.3% RDX * 29.2 ± 3.0% TNT * 21.0 ± 3.0% powdered aluminium * 4.7 ± 1.0% paraffin wax as a phlegmatizing agent. * 0.47 ± 0.1% calcium chloride Comp H-6 is used in a number of military applications, specifically as a explosive main fill, in munitions including aerial bombs such as the general purpose Mark 80 bombs in use with the USMC and US Navy (while USAF Mark 80s use a tritonal main fill); and underwater munitions (e.g. naval mines, depth charges and torpedoes) where it has generally replaced torpex, being less shock-sensitive and having more stable storage characteristics. It is approximately 1.35 times more powerful than pure TNT. Properties * Density: 1.73—1.74 g/cm3 * Velocity of detonation: 7,367 m/s Manufacture Australia is one of the largest manufacturers of Composition H-6, ori ...

Explosive
An explosive (or explosive material) is a reactive substance that contains a great amount of potential energy that can produce an explosion if released suddenly, usually accompanied by the production of light, heat, sound, and pressure. An explosive charge is a measured quantity of explosive material, which may either be composed solely of one ingredient or be a mixture containing at least two substances. The potential energy stored in an explosive material may, for example, be * chemical energy, such as nitroglycerin or grain dust * pressurized gas, such as a gas cylinder, aerosol can, or BLEVE * nuclear energy, such as in the fissile isotopes uranium-235 and plutonium-239 Explosive materials may be categorized by the speed at which they expand. Materials that detonate (the front of the chemical reaction moves faster through the material than the speed of sound) are said to be "high explosives" and materials that deflagrate are said to be "low explosives". Explosives may al ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Naval Mine
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 or a particular vessel type, akin to anti-infantry vs. anti-vehicle mines. 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. Although international law requires signatory nations to declare mined areas, precise locations remain secret; and non-complying individ ...

Composition C
The Composition C family is a family of related US-specified plastic explosives consisting primarily of RDX. All can be moulded by hand for use in demolition work and packed by hand into shaped charge devices. Variants have different proportions and plasticisers and include composition C-2, composition C-3, and composition C-4. History The term ''composition'' is used for any explosive material compounded from several ingredients. In particular, in the 1940s the format "Composition " was used for various compositions of the (relatively) novel explosive RDX, such as Composition B and other variants. Development The original material was developed by the British during World War II, and was used in the Gammon bomb. It was standardised as Composition C when introduced to US service. This material consisted of 88.3% RDX and a mineral oil-based plasticiser and phlegmatiser. It suffered from a relatively limited range of serviceable temperatures, and was replaced by Composition C-2 ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amatol
Amatol is a highly explosive material made from a mixture of TNT and ammonium nitrate. The British name originates from the words ammonium and toluene (the precursor of TNT). Similar mixtures (one part dinitronaphthalene and seven parts ammonium nitrate) were known as Schneiderite in France. Amatol was used extensively during World War I and World War II, typically as an explosive in military weapons such as aircraft bombs, shells, depth charges, and naval mines.Brown, G. I. (1998). ''The Big Bang: A History of Explosives''. Sutton Publishing . pp. 158-163. It was eventually replaced with alternative explosives such as Composition B, Torpex, and Tritonal. Invention Following the Shell Crisis of 1915 in which the UK did not have enough ordnance due to a lack of explosives, a team at the Royal Arsenal laboratories produced a mixture of ammonium nitrate and TNT, known as Amatol for short. Special factories were constructed for the manufacture of ammonium nitrate by the double dec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Minol (explosive)
Minol (pronounced ''mine-ol'') is a military explosive developed by the Admiralty early in the Second World War to augment supplies of trinitrotoluene (TNT) and RDX, which were in short supply. The aluminium component in Minol significantly prolongs the explosive pulse, making it ideal for use in underwater naval weapons (e.g. naval mines, for which it was developed, depth charges and torpedoes) where munitions with a longer explosive pulse are more destructive than those with high brisance. Minol cannot be used in weapons fired from gun barrels (e.g. artillery shells) because there is a risk of detonation when subjected to over 250 gs of acceleration. Typically, four Minol formulas were used. All percentages shown are by weight: * Minol-1: 48% TNT, 42% ammonium nitrate and 10% powdered aluminium * Minol-2: 40% TNT, 40% ammonium nitrate and 20% powdered aluminium * Minol-3: 42% TNT, 38% ammonium nitrate and 20% powdered aluminium * Minol-4: 40% TNT, 36% ammonium nitrate, 4% potas ...

Tritonal
Tritonal is a mixture of 80% Trinitrotoluene, TNT and 20% aluminium Powder (substance), powder, used in several types of ordnance such as air-dropped bombs. The aluminium improves the total heat output and hence Impulse (physics), impulse of the TNT — the length of time during which the blast wave is positive. Tritonal is approximately 18% more powerful than TNT alone. The 87 kilogram, kg of tritonal in a Mark 82 bomb has the potential to produce approximately 863 Joule#Megajoule, MJ of energy when detonated. This implies an energy density of approximately 9MJ/kg, compared to ~4MJ/kg for TNT.

Torpex
Torpex is a secondary explosive, 50% more powerful than TNT by mass. Torpex comprises 42% RDX, 40% TNT and 18% powdered aluminium. It was used in the Second World War from late 1942, at which time some used the names Torpex and RDX interchangeably, much to the confusion of today's historical researchers. The name is short for ''torpedo explosive''. Torpex proved to be particularly useful in underwater munitions because the aluminium component had the effect of making the explosive pulse last longer, which increased the destructive power. Besides torpedoes, naval mines, and depth charges, Torpex was only used in the Upkeep, Tallboy and Grand Slam bombs as well as the drones employed in Operation Aphrodite. Torpex has long been superseded by H6 and Polymer-bonded explosive (PBX) compositions. It is therefore regarded as obsolete and Torpex is unlikely to be encountered except in old munitions or unexploded ordnance, although a notable exception to this is the Sting Ray lightwei ...

Torpedo
A modern torpedo is an underwater ranged weapon launched above or below the water surface, self-propelled towards a target, and with an explosive warhead designed to detonate either on contact with or in proximity to the target. Historically, such a device was called an automotive, automobile, locomotive, or fish torpedo; colloquially a ''fish''. The term ''torpedo'' originally applied to a variety of devices, most of which would today be called naval mine, mines. From about 1900, ''torpedo'' has been used strictly to designate a self-propelled underwater explosive device. While the 19th-century battleship had evolved primarily with a view to engagements between armored warships with naval artillery, large-caliber guns, the invention and refinement of torpedoes from the 1860s onwards allowed small torpedo boats and other lighter surface combatant , surface vessels, submarines/submersibles, even improvised fishing boats or frogmen, and later light aircraft, to destroy large shi ...

Depth Charge
A depth charge is an anti-submarine warfare (ASW) weapon. It is intended to destroy a submarine by being dropped into the water nearby and detonating, subjecting the target to a powerful and destructive Shock factor, hydraulic shock. Most depth charges use explosive, high explosive charges and a fuze set to detonate the charge, typically at a specific depth. Depth charges can be dropped by ships, patrol aircraft, and helicopters. Depth charges were developed during World War I, and were one of the first viable methods of attacking a submarine underwater. They were widely used in World War I and World War II, and remained part of the anti-submarine arsenals of many navies during the Cold War, during which they were supplemented, and later largely replaced, by anti-submarine homing torpedoes. A depth charge fitted with a nuclear warhead is also known as a "nuclear depth bomb". These were designed to be dropped from a patrol plane or deployed by an anti-submarine missile from a s ...

Trinitrotoluene
Trinitrotoluene (), more commonly known as TNT, more specifically 2,4,6-trinitrotoluene, and by its preferred IUPAC name 2-methyl-1,3,5-trinitrobenzene, is a chemical compound with the formula C6H2(NO2)3CH3. TNT is occasionally used as a reagent in chemical synthesis, but it is best known as an explosive material with convenient handling properties. The explosive yield of TNT is considered to be the standard comparative convention of bombs and asteroid impacts. In chemistry, TNT is used to generate charge transfer salts. History TNT was first prepared in 1863 by German chemist Julius Wilbrand and originally used as a yellow dye. Its potential as an explosive was not recognized for three decades, mainly because it was too difficult to detonate because it was less sensitive than alternatives. Its explosive properties were first discovered in 1891 by another German chemist, Carl Häussermann. TNT can be safely poured when liquid into shell cases, and is so insensitive that i ...
