MK 108 Cannon
The MK 108 (German: ''Maschinenkanone''—"machine cannon") was a 30 mm caliber autocannon manufactured in Nazi Germany, Germany during World War II by Rheinmetall‑August Borsig, Borsig for use in aircraft. The cannon saw widespread use as an anti-bomber weapon during the second half of the war, first seen in 1943 in the Messerschmitt Bf 110, Bf 110G-2 bomber destroyers and Messerschmitt Bf 109, Bf 109G-6/U4. Four MK 108's formed the main armament of the Messerschmitt Me 262, Me 262 the next year. It could be found on some versions or optional mountings on practically every other German fighter aircraft, fighter of the era. Development The weapon was developed as a private venture by the company in 1940 and was submitted to the ''Reich Air Ministry, Reichsluftfahrtministerium'' (RLM—Reich Aviation Ministry) in response to a 1942 requirement for a heavy aircraft weapon for use against the Allies of World War II, Allied heavy bombers appearing over German-controlled regions by ...

Royal Air Force Museum Cosford
The Royal Air Force Museum Cosford, located in Cosford in Shropshire, is a free (currently, 2022) museum dedicated to the history of aviation and the Royal Air Force in particular. The museum is part of the Royal Air Force Museum, a non-departmental public body sponsored by the Ministry of Defence and also a registered charity. The museum is spread over two sites in England; the other site is at the Royal Air Force Museum London at Colindale (near Hendon) in north London. History The London museum was officially opened at the Colindale (then part of Hendon) London site on 15 November 1972 by Queen Elizabeth II. The hangars housed just 36 aircraft at opening. Over the years, the collection increased and aircraft were stored at RAF stations around the country when they were not on display to the public. On 1 May 1979, the Cosford site was opened at RAF Cosford, one of the RAF stations which had been used to store the museum's collection of aircraft. On opening, the museum initi ...

Brisance
In explosives engineering, brisance (; , ) is the shattering capability of a high explosive, determined mainly by its detonation pressure. Practical uses Brisance is of practical importance for determining the effectiveness of an explosion in fragmenting shells, bomb casings, grenades, structures, and the like. The sand crush teand Trauzl lead block test are commonly used to determine the relative brisance in comparison to TNT (which is considered a standard reference for many purposes). The value of brisance depends on the application. At one extreme, if an explosive is to be used for propulsion, e.g. by driving a piston or a bullet, brisance is likely to be undesirable, because the objective will be to ''move'' the load, not to shatter it or the engine or firearm, nor to produce a loud report. Such propulsive charges are designed to burn controllably, such as carburetted fuel/air mixes in vehicle piston engines, or nitrocellulose fibres or grains of controlled textures in fir ...

Mine Shell
A mine shell (from the German term ''Minengeschoß'', "mine shot"), also known as High-Explosive, High-Capacity (HEHC) in British military nomenclature, is a military explosive shell type characterized by thin (usually steel) shell walls and a correspondingly high quantity of explosives, much higher than the traditional high explosive shell type per caliber, meaning that mine shells trade fragmentation effect (due to the thinner shell walls) for a higher pressure wave effect when comparing to traditional high explosive shells. Mine shells were originally developed during the mid to late 1800s against fortresses prior to rebar but got a new role during World War II against air targets as reinforced fortresses had made the original use of the type obsolete around World War I. Effect, construction and use The mine shell is a more explosive version of the common high-explosive and high-explosive fragmentation shells, relying on inflicting damage primarily through the blast (pressu ...

Incendiary Ammunition
Incendiary ammunition is a type of ammunition that contains a chemical that, upon hitting a hard obstacle, has the characteristic of causing fire/setting flammable materials in the vincinity of the impact on fire. World War I The first time incendiary ammunition was widely used was in World War I, more specifically in 1916. At the time, phosphorus was the primary ingredient in the incendiary charge and ignited upon firing, leaving a trail of blue smoke. These early forms were also known as "smoke tracers" because of this. Though deadly, the effective range of these bullets was only 350 yards (320 m), as the phosphorus charge burned quickly. Incendiary bullets called "Buckingham" ammunition were supplied to early British night fighters for use against military zeppelins threatening the British Isles. The flammable hydrogen gas of the zeppelins made incendiary bullets much more deadly than standard ones which would pass through the outer skin without igniting the gas. Similar ...

High-Explosive Ammunition
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 * pressure, pressurized gas compressor, gas, such as a gas cylinder, aerosol can, or Boiling liquid expanding vapor explosion, BLEVE * nuclear weapon, 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 Detonation, detonate (the front of the chemical reaction moves faster through the material than the speed of sound) are said to be "high ...
