MK 108
The MK 108 (German: ''Maschinenkanone''—"machine cannon") is a 30 mm caliber autocannon manufactured in Germany during World War II by Rheinmetall‑ Borsig for use in aircraft. Development The weapon was developed as a private venture by the company in 1940 and was submitted to the '' Reichsluftfahrtministerium'' (RLM—Reich Aviation Ministry) in response to a 1942 requirement for a heavy aircraft weapon for use against the Allied heavy bombers appearing over German-controlled regions by then. Testing verified that the autocannon was well suited to this role, requiring on average just four hits with its 85g RDX-load (in a 330g shell) and a resulting strongly brisant high-explosive ammunition, to bring down a heavy bomber such as a B-17 Flying Fortress or B-24 Liberator, and just a single "shattering" hit to down a fighter. In comparison, the otherwise excellent 20 mm MG 151/20 (18g of HE in a 92g shell) required about 15 to 20 hits to down a B-17. The MK 108 was qu ...

Royal Air Force Museum Cosford
The Royal Air Force Museum Midlands, located at RAF Cosford in Shropshire, is a free 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 initially exh ...

MG 151 Cannon
The ''Maschinengewehr'' (MG) 151 is a belt-fed autocannon for aircraft use, developed in Nazi Germany from 1934 to 1940 and produced by Waffenfabrik Mauser during World War II. It was originally produced in 15.1 mm caliber from 1940, with a 15×96mm cartridge, but due to demand for higher effect against aircraft, especially with the introduction of mine shells for the 20 mm MG-FF/M aircraft cannon, the design was rechambered to 20 mm caliber in 1941, using a newly developed 20×82mm cartridge which traded projectile velocity for explosive power. The initial 15 mm variant then became known as the MG 151/15, with the new 20 mm variant becoming the MG 151/20. The MG 151/20 cannon was widely used on German Luftwaffe combat aircraft throughout World War II, mainly as offensive armament, but also seeing some use as defensive guns. Existing MG 151/15 guns saw use as aircraft armament throughout the war, albeit more limited compared to the MG 151/20, but also as ...

High-explosive Incendiary
In warfare, high-explosive incendiary (HEI) is a type of ammunition specially designed to impart energy and therefore damage to its target in one or both of two ways: via a high-explosive charge and/or via its incendiary (fire-causing) effects. Each round—by definition—has both capabilities. HEI ammunition is fused either mechanically or chemically. The armor-piercing ability can vary widely, allowing for more focused fragmentation or larger scatter. History HEI ammunition was originally developed for use in large-caliber cannon, howitzer and naval artillery Artillery consists of ranged weapons that launch Ammunition, munitions far beyond the range and power of infantry firearms. Early artillery development focused on the ability to breach defensive walls and fortifications during sieges, and l .... Currently, HEI rounds are most commonly made in medium-caliber sizes of 20, 25, 30, and 35 mm. They are fired from various platforms, including aircraft, anti-aircr ...

Mine Shell
A mine shell (from , "mine shot") or high-explosive, high-capacity (HEHC) in British military nomenclature, is a military explosive shell type characterized by thin (usually steel) shell walls which allow a much higher explosive content than standard high-explosive shells of the same caliber, trading a higher pressure wave effect against high-explosive shells' larger fragmentation effect and better penetration of armoured targets. Mine shells were originally developed during the mid- to late 1800s against fortresses before the introduction of rebar; reinforced fortresses had made the original use of the type obsolete around World War I, but they were given a new role against aircraft during World War II. 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 (pressure wave) alone rather than the higher fragmentation but less blas ...

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 vicinity 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 device, 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 metre, 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 i ...

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 * pressurized gas, such as a gas cylinder, aerosol can, or boiling liquid expanding vapor explosion * 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 ...

Armor-piercing Shot And Shell
Armour-piercing ammunition (AP) is a type of projectile designed to penetrate armour protection, most often including naval armour, body armour, and vehicle armour. The first, major application of armour-piercing projectiles was to defeat the thick armour carried on many warships and cause damage to their lightly armoured interiors. From the 1920s onwards, armour-piercing weapons were required for anti-tank warfare. AP rounds smaller than 20 mm are intended for lightly armoured targets such as body armour, bulletproof glass, and lightly armoured vehicles. As tank armour improved during World War II, anti-vehicle rounds began to use a smaller but dense penetrating body within a larger shell, firing at a very-high muzzle velocity. Modern penetrators are long rods of dense material like tungsten or depleted uranium (DU) that further improve the terminal ballistics. Penetration In the context of weaponry, ''penetration'' is the ability of a weapon or projectile to pierce ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Rim (firearms)
A rim is an external flange that is machined, cast, molded, stamped, or pressed around the bottom of a firearms cartridge. Thus, rimmed cartridges are sometimes called "flanged" cartridges. Almost all cartridges feature an extractor or headspacing rim, in spite of the fact that some cartridges are known as "rimless cartridges". The rim may serve a number of purposes, including providing a lip for the extractor to engage, and sometimes serving to headspace the cartridge. Types There are various types of firearms rims in use in modern ammunition. The main types are categorized as rimmed, rimless, semi-rimmed, rebated, and belted. These describe the size of the rim in relation to the base of the case. Rimmed The rimmed cartridge, sometimes called flanged cartridge, is the oldest of the types and has a rim that is significantly larger in diameter than the base of the cartridge. Rimmed cartridges use the rim to hold the (usually straight sided) cartridge in the chamber of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

30mm Ammo
3 (three) is a number, numeral and digit. It is the natural number following 2 and preceding 4, and is the smallest odd prime number and the only prime preceding a square number. It has religious and cultural significance in many societies. Evolution of the Arabic digit The use of three lines to denote the number 3 occurred in many writing systems, including some (like Roman and Chinese numerals) that are still in use. That was also the original representation of 3 in the Brahmic (Indian) numerical notation, its earliest forms aligned vertically. However, during the Gupta Empire the sign was modified by the addition of a curve on each line. The Nāgarī script rotated the lines clockwise, so they appeared horizontally, and ended each line with a short downward stroke on the right. In cursive script, the three strokes were eventually connected to form a glyph resembling a with an additional stroke at the bottom: ३. The Indian digits spread to the Caliphate in the 9th ...

Messerschmitt Bf 109
The Messerschmitt Bf 109 is a monoplane fighter aircraft that was designed and initially produced by the Nazi Germany, German aircraft manufacturer Messerschmitt#History, Bayerische Flugzeugwerke (BFW). Together with the Focke-Wulf Fw 190, the Bf 109 formed the backbone of the ''Luftwaffe's'' fighter force during the World War II. It was commonly called the Me 109 by Allied aircrew and some German aces/pilots, even though this was not the official model designation. The Bf 109 was designed by Willy Messerschmitt and Robert Lusser, who worked at BFW during the early to mid-1930s. It was conceived as an interceptor aircraft, interceptor. However, later models were developed to fulfill multiple tasks, serving as Escort fighter, bomber escort, fighter-bomber, day fighter, day-, night fighter, night-, all-weather fighter, ground-attack aircraft, and aerial reconnaissance aircraft. It was one of the most advanced fighters when the fighter first appeared, being furnished with an all-me ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
