Berezin B-20
The Berezin B-20 (Березин Б-20) was a 20 mm caliber autocannon used by Soviet aircraft in World War II. Development The B-20 was created by Mikhail Yevgenyevich Berezin in 1944 by converting his 12.7 mm Berezin UB machine gun to use the 20 mm rounds used by the ShVAK cannon. No other changes were made to the weapon which was pneumatically or mechanically charged and was available in both synchronized and unsynchronized versions. In 1946, an electrically-fired version was created for the turrets of the Tupolev Tu-4 bomber until the Nudelman-Rikhter NR-23 cannon became available. The B-20 was a welcome replacement for the ShVAK because it was significantly lighter - 25 kg (55 lb) to the 40 kg (80 lb) ShVAK - without sacrificing rate of fire or muzzle velocity. Specifications * Ammunition: 20×99mm * Empty weight: 25 kg (55 lb) * Muzzle velocity: 750–770 m/s (2,460-2,525 ft/s) * Rate of fire: 800 rounds/min * Mass of ...

USSR
The Soviet Union,. officially the Union of Soviet Socialist Republics. (USSR),. was a transcontinental country that spanned much of Eurasia from 1922 to 1991. A flagship communist state, it was nominally a federal union of fifteen national republics; in practice, both its government and its economy were highly centralized until its final years. It was a one-party state governed by the Communist Party of the Soviet Union, with the city of Moscow serving as its capital as well as that of its largest and most populous republic: the Russian SFSR. Other major cities included Leningrad (Russian SFSR), Kiev ( Ukrainian SSR), Minsk ( Byelorussian SSR), Tashkent (Uzbek SSR), Alma-Ata (Kazakh SSR), and Novosibirsk (Russian SFSR). It was the largest country in the world, covering over and spanning eleven time zones. The country's roots lay in the October Revolution of 1917, when the Bolsheviks, under the leadership of Vladimir Lenin, overthrew the Russian Provisional Gove ...

Aircraft Guns Of The Soviet Union
An aircraft is a vehicle that is able to fly by gaining support from the air. It counters the force of gravity by using either static lift or by using the dynamic lift of an airfoil, or in a few cases the downward thrust from jet engines. Common examples of aircraft include airplanes, helicopters, airships (including blimps), gliders, paramotors, and hot air balloons. The human activity that surrounds aircraft is called ''aviation''. The science of aviation, including designing and building aircraft, is called ''aeronautics.'' Crewed aircraft are flown by an onboard pilot, but unmanned aerial vehicles may be remotely controlled or self-controlled by onboard computers. Aircraft may be classified by different criteria, such as lift type, aircraft propulsion, usage and others. History Flying model craft and stories of manned flight go back many centuries; however, the first manned ascent — and safe descent — in modern times took place by larger hot-air ...

Autocannons Of The Soviet Union
An autocannon, automatic cannon or machine cannon is a fully automatic gun that is capable of rapid-firing large-caliber ( or more) armour-piercing, explosive or incendiary shells, as opposed to the smaller-caliber kinetic projectiles (bullets) fired by a machine gun. Autocannons have a longer effective range and greater terminal performance than machine guns, due to the use of larger/heavier munitions (most often in the range of , but bigger calibers also exist), but are usually smaller than tank guns, howitzers, field guns or other artillery. When used on its own, the word "autocannon" typically indicates a non-rotary weapon with a single barrel. When multiple rotating barrels are involved, such a weapon is referred to as a "rotary autocannon" or occasionally "rotary cannon", for short (particularly on aircraft). Autocannons are heavy weapons that are unsuitable for use by infantry. Due to the heavy weight and recoil, they are typically installed on fixed mounts, wh ...

Hispano HS
The term ''Hispanic'' ( es, hispano) refers to people, cultures, or countries related to Spain, the Spanish language, or Hispanidad. The term commonly applies to countries with a cultural and historical link to Spain and to viceroyalties formerly part of the Spanish Empire following the Spanish colonization of the Americas, parts of the Asia-Pacific region and Africa. Outside of Spain, the Spanish language is a predominant or official language in the countries of Hispanic America and Equatorial Guinea. Further, the cultures of these countries were influenced by Spain to different degrees, combined with the local pre-Hispanic culture or other foreign influences. Former Spanish colonies elsewhere, namely the Spanish East Indies (the Philippines, Marianas, etc.) and Spanish Sahara (Western Sahara), were also influenced by Spanish culture, however Spanish is not a predominant language in these regions. Hispanic culture is a set of customs, traditions, beliefs, and art forms (music ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ho-5 Cannon
The Ho-5 (Army Type 2) was a Japanese aircraft autocannon used during World War II. Developed from the Ho-103 machine gun, it was a version of the American Model 1921 Browning aircraft machine gun. It replaced the Ho-1 and Ho-3 (Army Type 97) in general service. The Ho-5 was belt-fed using typical Browning-style steel disintegrating links. The cartridge used was a shortened version of the Allied 20 x 110mm Hispano-Suiza HS.404. The Ho-5 was used mostly as wing mounts in late-war fighters, but saw limited use as cowl mounted in fighters and as flexible mounted (retrofit) in bombers. Specifications *Caliber: 20mm (0.8 in) *Ammunition: 20 x 94 (84.5 g) *Weight: 37 kg (77 lb) *Rate of fire: 750 rounds/min * Muzzle velocity: 750 m/s (2,460 ft/s) *Magazine: 150-round belt See also *List of firearms *List of weapons of military aircraft of Germany during World War II *List of common World War II infantry weapons This is a list of infantry weapons which were used in World W ...

MG 151 Cannon
The MG 151 (MG 151/15) was a German 15 mm aircraft-mounted autocannon produced by Waffenfabrik Mauser during World War II. Its 20mm variant, the 20 mm MG 151/20 cannon, was widely used on German Luftwaffe Fighter aircraft, fighters, night fighters, fighter-bombers, bombers and ground-attack aircraft. Salvaged guns saw post-war use by other nations. Development and wartime history (MG 151/20) The pre-war German doctrine for arming single-engine fighter aircraft mirrored that of the French. This doctrine favoured a powerful autocannon mounted between the cylinder banks of a V engine and firing through the propeller hub, known as a ''moteur-canon'' in French (from its first use with the Hispano-Suiza 8#Variants, Hispano-Suiza HS.8C engine in World War I, on the SPAD S.XII) and by the cognate ''Motorkanone'' in German by the 1930s. The weapon preferred by the French in this role was the most powerful 20mm Oerlikon of the time, namely the Oerlikon 20 mm cannon, FFS model, b ...

MG FF Cannon
The MG FF was a drum-fed, blowback-operated, 20 mm aircraft autocannon, developed in 1936 by Ikaria Werke Berlin of Germany. It was a derivative of the Swiss Oerlikon FF F cannon (its ''FF'' suffix indicating ''Flügel Fest'', for a fixed-mount, wing location from the Swiss original), with the Oerlikon FF design itself a development of the Imperial German World War I Becker 20 mm cannon, and was designed to be used in space-limited, fixed mountings such as inside aircraft wings, although it saw use as both an offensive and a defensive weapon, in both fixed and flexible format. It saw widespread use in those roles by the German Luftwaffe, particularly during the early stages of World War II, although from 1941 onwards it was gradually replaced by the Mauser firm's 20 mm MG 151/20, which was lighter, and had both a higher rate of fire and muzzle velocity. Development MG FF stands for ''Maschinengewehr Flügel Fest'', which translates into "machine gun, wing, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Muzzle Velocity
Muzzle velocity is the speed of a projectile (bullet, pellet, slug, ball/shots or shell) with respect to the muzzle at the moment it leaves the end of a gun's barrel (i.e. the muzzle). Firearm muzzle velocities range from approximately to in black powder muskets, to more than in modern rifles with high-velocity cartridges such as the .220 Swift and .204 Ruger, all the way to for tank guns firing kinetic energy penetrator ammunition. To simulate orbital debris impacts on spacecraft, NASA launches projectiles through light-gas guns at speeds up to . Projectile velocity For projectiles in unpowered flight, its velocity is highest at leaving the muzzle and drops off steadily because of air resistance. Projectiles traveling less than the speed of sound (about in dry air at sea level) are ''subsonic'', while those traveling faster are ''supersonic'' and thus can travel a substantial distance and even hit a target before a nearby observer hears the "bang" of the shot.

20×99mm
20 mm caliber is a specific size of popular autocannon ammunition. It is typically used to distinguish smaller-caliber weapons, commonly called "guns", from larger-caliber "cannons" (e.g. machine gun vs. autocannon). All 20 mm cartridges have an outside projectile (bullet) diameter and barrel bore diameter of . These projectiles are typically long, cartridge cases are typically long, and most are shells, with an explosive payload and detonating fuze. Weapons using this caliber range from anti-materiel rifles and anti-tank rifles to aircraft autocannons and anti-aircraft guns. Usage Twenty-millimeter-caliber weapons are generally not used to target individual soldiers, but have targets such as vehicles, buildings, or aircraft. Types of ammunition *High explosive (HE) *High explosive incendiary (HEI) *Armor-piercing (AP) * Semi-armor-piercing high explosive incendiary (SAPHEI) *Armor-piercing discarding sabot (APDS) *High explosive fragmentation tracer (HEF-T) * High ex ...
