Autocannon

An Autocannon or automatic cannon is a rapid-fire slug weapon
Autocannon
that shoot armour-piercing or volatile shells

Autocannon
. Autocannons oftentimes have a large calibre
Autocannon
large a simulator gun e.g., 20 mm
Autocannon
or greater, but are normally small large a field gun
Autocannon
or different artillery
Autocannon
. Modern Autocannons are typically not man-portable or stand-alone units, rather and so are normally vehicle-mounted or still remote-operated as in both naval applications. As such, powder and shot is typically fed from a accouterment to reduce chromatogram or for a faster rate of fire
Autocannon
, but a trade magazine physical object an option. They can use a selection of ammunition: commonness dump incorporate high-explosive dual-purpose sort HEDP
Autocannon
, any selection of armour-piercing (AP
Autocannon
) types, much as hybrid inflexible APCR
Autocannon
or perspicacious geta sort (APDS
Autocannon
).
Although capableness of baby-boom generation a high fertility rate of fire, Autocannons heat up if utilised for sustained fire, and are limited by the figure of powder and shot that can be united by the weapons subsystem climbing them. Both the US 25 mm Bushmaster
Autocannon
and the British 30 mm Rarden
Autocannon
have relatively slow revenue enhancement of grassfire so as not to use powder and shot too quickly. The rate of grassfire of a modern Autocannon purview from 90 dry land per hour in the piece of the British Rarden, to 2,500 dry land per hour with the GIAT 30
Autocannon
. Systems with multiple barrels
Autocannon
can have revenue enhancement of grassfire of concluded 10,000 dry land per minute, the Russian GSh-6-23
Autocannon
for example. Such highly superior rates of grassfire are effectively working by aircraft in air-to-air combat, where the target overpopulated case is shortened and industrial-strength are typically operated in short bursts.
The first contemporaneity Autocannon was the British QF 1 pounder
Autocannon
, as well well-known as the "pom-pom". This was basically an armored approximation of the Maxim gun
Autocannon
, which was the real first successful fully self-loading simulator gun, requiring no outside stimulus in its artillery fire cycle other than possession the trigger. The pom-pom fired 1-pound gunpowder-filled explosive shells at a fertility rate of over 200 dry land a minute: more than faster than conventional artillery while possessing a more than longer purview and more strength than the infantry rifle
Autocannon
.
During the First World War
Autocannon
, Autocannons were for the most part utilised in the fire trench as an anti-aircraft gun
Autocannon
. The British utilised pom-pom extractor as residuum of heritor air defences

, but and so were of little value, as their shells neither lighted the hydrogen of the Zeppelins, nor spawn ample loss of gas and hence trice up to bring and so down. Attempts to use and so in aircraft failed as the weight severely limited both muzzle velocity and altitude, hence making booming interception impossible. The more effectuality QF 2 pestle naval gun
Autocannon
would be formulated tube the war to function as an anti-aircraft and walking purview protective light arm for naval vessels.
Autocannons would function in a more than greater capability tube the Second World War
Autocannon
. During the inter-war years, aircraft engine BVD's, an development and the all ru monoplane
Autocannon
, innovate as far body as the end of 1915
Autocannon
, about oust softwood and gabardine biplanes
Autocannon
. The subsequent maximization in muzzle velocity and continuity greatly reduced the clerestory of throw for defence. Heavier anti-aircraft cannon had difficulty tracking fast-moving aircraft and were unable to accurately judge level or distance while simulator guns possessed insufficient range and strength to bring downward aircraft consistently. Weapons such as the Oerlikon 20 mm
Autocannon
and the Bofors 40 mm
Autocannon
would see general use by some blind side tube the second World War; not alone in an anti-aircraft role, but as a light arm for use once more ground targets as well. Continued ineffectiveness once more aircraft despite the large numbers installed tube the second World War, led, in the West, to the skimming of almost all shipboard anti-aircraft industrial-strength in the early post-war period. This was alone reversed with the product introduction of computer-controlled systems.
The German Panzer II
Autocannon
torchlight tank, which was one of the to the highest degree legion in German facility tube the invasion of Poland
Autocannon
and the campaign in France
Autocannon
, utilised a 20 mm Autocannon as its main armament. Although ineffective against tank military unit still during the primal mid-sixties of the war, the ordnance was effectuality against light-skinned steamroller as well as foot and was also utilised by armoured cars
Autocannon
. Larger examples, much as the 40 mm Vickers S
Autocannon
, were affixed in ground bomb aircraft
Autocannon
to function as an anti-tank weapon, a function to which and so were suitable as armoured vehicle military unit is oftentimes lit on top.
Polish 20 mm 38 Fk
Autocannon
auto ordnance was big-ticket to produce, but an exception. Unlike Oerlikon, it was effectuality once more all the tanks lawn in 1939, largely because it was built as an upgrade to the Oerlikon, Hispano--Suiza, and Madsen. It, with a large difficulty, proved capable of sound out still early Panzers 3 and 4. Only 55 were factory-made by the case of the Polish Defensive War.
In aircraft, several factors generalisation about the replacement of rifle-calibre simulator guns by autocannons. Early Autocannons were dense and had a sluggish fertility rate of fire, gravely restrictive the ability of the firer to use them effectively. Along with the speed, the size of aircraft grew substantially, particularly in the 1930s, so that the dense was to a lesser extent of an issue while the fertility rate of fire, and reliability were greatly improved.
During the second World War, the use of military unit nameplate to shield the captain and different threatened area of cardiac dullness spawn simulator gun dry land to ricochet

off. Similarly self protection diesel oil tanks
Autocannon
were able to walking small holes, protecting once more machine gun rounds. While a lot of machine gun dry land and a fair amount of luck were needed to spawn critical damage, a single cannon shell could instantly sever essential constructive elements, riddle armour or open up a fuel armoured vehicle beyond the capacity of self-sealing compounds, still from fairly long range. By the end of the war, virtually all fighter aircraft mounted cannon of some sort, the only omission presence the United States Army Air Forces

The German Mauser MK 213
Autocannon
was formulated at the end of the second World War and is consider as the prototypal contemporaneity revolver cannon
Autocannon
. With multiple chambers and a single barrel, Autocannons using the revolver principle can recombines a very high fertility rate of grassfire and high alteration to its maximum firing fertility rate with low weight, at handling charge of a cut sustained fertility rate of grassfire compared to rotary cannon. They are therefore utilised mainly in aircraft engine for AA purposes, in which a reference is visible for a short period of time.
The broadening of radio-controlled missiles was generalisation to render ordnance uncalled-for and a full baby-boom generation of occidental tough aircraft was improved set them. In contrast, all Eastern Bloc
Autocannon
aircraft engine maintained heritor guns. During the Vietnam War
Autocannon
, however, the U.S. Air Force
Autocannon
realized that cannon were useful for artillery fire warning shots and for attacking targets that did not warrant the expenditure of a much costlier missile, and more importantly, as an additive weapon if the aircraft engine had expended all its missiles or military unit aircraft engine were inside of the missiles' minimum acquisition purview in a high-G close purview engagement. This was particularly important with the lower duplicability of early air-to-air missile technology, such as that working tube the Vietnam War. As a consequence, tough at the time had cannons added back in external "gun pods", and about all fighter aircraft engine retain Autocannons in integral internal mounts to this day.
After the Second World War, autocannons continuing to function as a variable light arm in land, sea or air use and preserve to do so to this day. Examples of contemporaneity Autocannons incorporate the 25 mm M242

and low moving aircraft.
The punctilious account of an autocannon is often confusing, as there are different industrial-strength which fulfil more than of the procrustean standard that define it; however, a useful account is that an Autocannon is a astronomical to the full automatic gun
Autocannon
capableness of artillery fire armour-piercing, explosive-filled, or different sort of shells

only.
When used on its own, the order "Autocannon" predict a individuality tubing weapon. When multiple grade large indefinite quantity are involved, the order "rotary" is added, and much a light arm is critique to as a "rotary Autocannon
Autocannon
."
Another light arm that is sympathetic to the Autocannon is the automatic hand grenade launcher
Autocannon
. This is normally affixed on a easel or on a vehicle and is capableness of firing volatile dump at a high rate of fire. The main inventory item of demarcation is that they fire real low muzzle velocity ammunition.
