Query: How fast is the fastest firing machine gun?
This is the mechanical rate of fire, or how fast the weapon "cycles" (loads, locks, fires, unlocks, ejects). Measurement of the cyclic rate assumes that the weapon is being operated as fast as possible and does not consider operator tasks (magazine changes, aiming, etc.). When the trigger is pulled, the rate at which rounds are fired is the cyclic rate. Typical cyclic rates of fire are 600–900 RPM for assault rifles, 1,000-1,100 RPM in some cases, 900-1,200 RPM for submachine guns and machine pistols, and 600-1,500 RPM for machine guns. M134 Miniguns mounted on attack helicopters and other combat vehicles can achieve rates of fire of over 100 rounds per second (6,000 RPM). Cyclic rate of fire is the only rate that can be determined precisely.
Fast draw is one of the fastest sports in the world. Every time is measured under one second, from the signal to draw to when the timer is stopped. The current World Fast Draw Association (WFDA) record for Open Class Fast Draw in an event called Standing Balloons is .208 seconds - and that includes the time it takes to react, draw, fire and pop a balloon target at eight feet away. A world class competitor can draw and fire a shot in under half a second. Given that the average human reaction time is around 0.2 to 0.25 seconds, the round is over before most people can react. The reaction times of the best fast draw shooters is 0.145 seconds, which means that the gun is cocked, drawn, aimed (from the hip), and fired in just over 0.06 seconds. To establish a World Fast Draw Association record, a second shot must be fired in the same competition that is no more than 0.30 seconds slower than the first; this is intended to prevent a shot that anticipates the start signal from setting a record. In competitions where two rounds must be fired, at separate targets, less than 0.10 seconds separate the shots.
Two notable artillery-sized volley guns were developed in the mid-19th century, although neither was particularly successful in practice. Developed in the 1860s and based on an 1850s design by a captain Fafschamps, the French mitrailleuse is an example of a multi-barreled volley gun that could fire all of its barrels simultaneously or sequentially over a short period of time. Also developed in the 1860s, General Origen Vandenburgh of the New York State Militia designed a weapon that had eighty five parallel .50 caliber rifle barrels. After failing to sell the weapon to the United Kingdom, he reportedly sold a small number to the Confederate States of America, although there is no record that they were actually used. One Vandenburgh gun was located at Fort Fisher, North Carolina, and another reportedly at Salisbury, NC.
Richard Jordan Gatling (September 12, 1818 – February 26, 1903) was an American inventor best known for his invention of the Gatling gun, considered to be the first successful machine gun, though it is not a true machine gun by modern definitions.
In service, the Breda 37 and 38 proved to be fairly reliable heavy machine guns. Perhaps because the heavy support weapons received more attention from their crews, field reports were generally positive except for jams caused by desert sand and dust, which in the Western Desert affected all infantry machine guns to some extent. The Breda 37's slow rate of fire helped prevent overheating during continuous fire, and its powerful, heavy-bullet cartridge had excellent range and penetration. Still, this machine gun was almost twice as heavy as the German machine guns and heavier than weapons like the M1919. In fact, it was the heaviest World War II 'light' machine gun, and unnecessarily complex to use and deploy. This was another issue for Italians, whose mobility was limited by their weak truck fleet. The tripod added around 20 kg to the complex, putting it at around 40 kilograms.
A few hand-held volley guns were also developed during the 18th and 19th centuries. One of the most distinctive was the ""duck's foot"" volley gun, a pistol with multiple barrels arranged in a splayed pattern, so that the firer could spray a sizable area with a single shot. The principle behind this type of pistol is one of confrontation by one person against a group; hence, it was popular among bank guards, prison wardens and sea captains in the early 19th century.
A machine gun is still referred to as a "mitrailleuse" in French, following the pattern set by the adoption of the "Mitrailleuse Hotchkiss" in 1897. The FN 5.56 mm NATO machine gun, the Minimi, derives its name from the term "Mini-Mitrailleuse", "small machine gun". Submachine guns may be called "mitraillettes", the diminutive of "mitrailleuse", although they are also called "pistolets mitrailleurs" ("mitrailleuse pistols").
The F7s are major contenders for the fastest steam locomotives ever built, as they ran at over daily. One run in January 1941 recorded by a reporter for "Trains" magazine saw achieved twice—in the midst of a heavy snowstorm. Baron Gérard Vuillet, a French railroading expert, once recorded a run between Chicago and Milwaukee where the locomotive reached and sustained an average for . However, the British locomotive LNER Class A4 4468 "Mallard" is officially accepted to be the world's fastest, with a run recorded at but authenticated at 126 mph in 1938.
Depending on the rifle, bullets typically travel between 800 and 1000 m/s (2600 and 3400 feet per second) at the moment they leave the rifle's barrel. The bullet slows down considerably due to friction with the air over a distance. The distance a bullet will travel is determined by its shape, weight, launch velocity and launch angle as with any projectile, the study of which is referred to as external ballistics.
Sir Hiram Stevens Maxim (5 February 1840 – 24 November 1916) was an American-born British inventor, best known as the creator of the Maxim gun, the first portable fully automatic machine gun. Maxim held patents on numerous mechanical devices such as a mousetrap, hair-curling irons, and steam pumps, and laid claim to inventing the lightbulb. He also experimented with powered flight but his large aircraft designs were never successful, however, his "Captive Flying Machine" amusement ride, designed as a means by which to fund his research while generating public interest in flight, was highly successful.
This is a list of the fastest flying birds in the world. A bird's velocity is necessarily variable; a hunting bird will reach much greater speeds while diving to catch prey than when gliding. The bird with the greatest airspeed velocity is the Peregrine falcon, able to exceed 321.8 km/h (200 mph) in its hunting dives. The greatest self-powered horizontal speed is achieved by Homing Racing Pigeons. They can fly 1100 km (700 miles) in a single day, and they have been recorded flying at 177 km/h (110 miles per hour), making them the birds with the fastest speed ever recorded on a self-powered flight, and the fastest endurance flight.
The fastest land animal is the cheetah, which has a recorded speed of . The peregrine falcon is the fastest bird and the fastest member of the animal kingdom with a diving speed of . The fastest animal in the sea is the black marlin, which has a recorded speed of .
Hawkes invented the first robotic machine gun, the "Telepresent Rapid Aiming Platform" (TRAP), the first weapon he designed. He had been inspired to create a safer way for police to deal with situations after watching a shootout in North Hollywood, Los Angeles on television.
Airsoft guns are replica weapons used in airsoft sports. They are a special type of very low-power smoothbore air guns designed to shoot non-metallic spherical projectiles often colloquially (and incorrectly) referred to as "BBs", which are typically made of (but not limited to) plastic or biodegradable resin materials. Airsoft gun powerplants are designed to have low muzzle energy ratings (generally less than 1.5 J, or 1.1 ft⋅lb) and the pellets have significantly less penetrative and stopping powers than conventional air guns, and are generally safe for competitive sporting and recreational purposes if proper protective gear is worn.
A fast craft is a vessel capable of speeds over 30 knots. HSICs (High Speed Interceptor Craft) however, trump fast craft with speeds of over 50 knots. HSICs are usually either custom or law enforcement craft. Law enforcement use these extremely fast boats to catch criminals such as smugglers or drug traffickers who use fast craft as well. The military have started to use HSICs to stop international threats such as pirates, militias, terrorists and weapons traffickers. Originally HSICs were not meant to carry large weapons. Now that the military is using them, they are being built with heavy machine guns. The boats have to be fitted with robust weight control and at the same time have heavy amour. HSICs must do without propellers to account for cavitation and vibrations. Instead HSICs use surface drivers or water jets.
It is the fastest land animal. Cheetahs can reach speeds of in short bursts, but the top end speed of the cheetah is disputed by more recent measurements. The average speed of a cheetah while hunting is about .
Air superiority depended on having the fastest, most maneuverable fighters, in sufficient quantity, based on well-supplied airfields, within range. The RAF demonstrated the importance of speed and maneuverability in the Battle of Britain (1940), when its fast Spitfire and Hawker Hurricane fighters easily riddled the clumsy Stukas as they were pulling out of dives. The race to build the fastest fighter became one of the central themes of World War II.
In the buildup to the Second World War, the United Kingdom had embarked on a programme to develop cannon-armed fighters. They acquired a licence to build the HS.404, which entered production as the Hispano Mk.I intended as aeroplane armament. Its first use was in the Westland Whirlwind of 1940, and later in the more powerful Bristol Beaufighter, providing the Royal Air Force with powerful cannon-armed interceptors. The experience of the Battle of Britain had shown the batteries of eight rifle-calibre machine guns to be inadequate and prompted the adoption of autocannon armament for the primary portion of Royal Air Force (RAF) fighters. The Beaufighter highlighted the need for a belt feed mechanism; as a night fighter the 60-round drums needed to be replaced in the dark by the Radar/Wireless Operator, often while the aircraft was manoeuvering to keep sight of its quarry. In addition, the early trial installations in the Hawker Hurricane and Supermarine Spitfire had shown a tendency for the gun to jam during combat manoeuvres, leading to some official doubt as to the suitability of cannon as the sole main armament. This led to the Air Ministry for a brief period specifying 12-machine gun armament for new fighters.
The fastest steam locomotive
Locomotive 498.106 ČSD, nicknamed Albatross, reached top speed 162 km/h on railway test circuit Velim (August 27, 1964)
The use of rapid firing machine guns and long range breech loading artillery quickly led to camouflaging of vehicles and positions. Artillery pieces were soon painted in contrasting bold colours to obscure their outlines. Another early trend was building observation trees, made of steel with bark camouflage. Such trees became popular with the British and French armies in 1916. The observation tree was invented by French painter Lucien-Victor Guirand de Scévola, who led the French army's camouflage unit, the first of its kind in any army. He also invented painted canvas netting to hide machine gun positions, and this was quickly taken up for hiding equipment and gun positions from 1917, 7 million square yards being used by the end of the war.
Open-wheeled racing is among the fastest in the world. Formula 1 cars can reach speeds in excess of . At Autodromo Nazionale Monza, Antônio Pizzonia of BMW Williams F1 team recorded a top speed of in the 2004 Italian Grand Prix. Since the end of the V10 era in 2006 speeds like this have not been reached, with contemporary machinery reaching around . It is difficult to give precise figures for the absolute top speeds of Formula 1 cars, as the cars do not have speedometers as such and the data are not generally released by teams. The 'speed traps' on fast circuits such as Monza give a good indication, but are not necessarily located at the point on the track where the car is travelling at its fastest. BAR Honda team recorded an average top speed of in 2006 at Bonneville Salt Flats with unofficial top speed reaching using modified BAR 007 Formula 1 car. Speeds on ovals can range in constant excess of , and at Indianapolis in excess of . Some sources claim that in 1996, Paul Tracy recorded a trap speed of at Michigan International Speedway. In 2000, Gil de Ferran set the one-lap qualifying record of at California Speedway. Even on tight non-oval street circuits such as the Grand Prix of Toronto, open-wheel Indy Cars attain speeds of .
One of the "Einheitsmaschinengewehr" (Universal machine gun) roles was to provide low level anti-aircraft coverage. A high cyclic rate of fire firing rate is advantageous for use against targets that are exposed to a general-purpose machine gun for a limited time span, like aircraft or targets that minimize their exposure time by quickly moving from cover to cover. For targets that can be fired on by a general-purpose machine gun for longer periods than just a few seconds the cyclic firing rate becomes less important. 
As a consequence one of the MG 42 most notable features was in its high cyclic rate of fire of about 1,200 to 1,500 rounds per minute, twice the rate of the Vickers and Browning machine guns, which fired at a rate of about 600 rounds per minute. The ear could not easily discern the sound of individual shots being fired, instead hearing a sound described as like "ripping cloth" or a buzzsaw.
The battalion mainly used the M-8 Light Armored Car, as it was fast, up to 56 mph (90 km/h), and gave some protection from small arms fire. M8 was equipped with a 37 mm gun and 6X6 wheel drive. The M8 was the main reconnaissance vehicle used by the US military in World War II. Also used was M20 scout car, which was a M-8 without the 37 mm gun and turret. In its place was an anti-aircraft ring mount for a .50-caliber machine gun. A bazooka was provided for the crew to compensate for its lack of anti-armor weaponry. With this vehicles, the 82nd could scout ahead of the slower M4 Sherman tank with a top speed of 25 mph to 30 mph. Also used for reconnaissance and to run messages Harley-Davidson WLA motorcycles were used by the 82nd as well. Almost all units used Jeeps as they were fast four-wheel drive utility vehicles.
The ShKAS was the fastest-firing rifle calibre aircraft armament in general service in World War II. A one-second burst from the four ShKAS of a Polikarpov I-153 or Polikarpov I-16 placed 120 bullets within 15 angular mils at 400 meters (1,312 feet) giving a firing density of 5 bullets per square meter of the sky. Moreover, the ShKAS was unusually light as well; the four guns, with 650 rounds of ammunition each, weighed a total of only 160 kg (350 lb).
ShKAS wasn't problem-free though. Soviet machine-gun technician Viktor M. Sinaisky recalled:Although chambered in the 7.62×54mmR, the ShKAS guns used cartridges specially built for them to smaller tolerances; to distinguish them from the regular 7.62 ammunition, the Cyrillic letter "Sh" (Ш) was imprinted on the bottom of the cases. The cases, designed by N. M. Elizarov, also had a few additional features like double crimping and a thicker case wall of "bimetallic" construction instead of the traditional brass. The main type of bullet used was armour-piercing incendiary B-32 bullet.Some military historians consider that feed system of the Mauser MG 213C (the seminal revolver cannon for Western designs) was inspired by the ShKAS.
During World War II, the MG 34 was superseded by a new GPMG, the MG 42, although it remained in combat use. The MG 42 was more efficient to manufacture, more robust, and had an extremely high cyclic rate of fire of 1,200 to 1,500 rounds per minute. One of the "Einheitsmaschinengewehr" (Universal machine gun) roles was to provide low level anti-aircraft coverage. A high cyclic rate of fire is advantageous for use against targets that are exposed to a general-purpose machine gun for a limited time span, like aircraft or targets that minimize their exposure time by quickly moving from cover to cover. For targets that can be fired on by a general-purpose machine gun for longer periods than just a few seconds the cyclic firing rate becomes less important. Arguably the finest all-round GPMG ever produced, it was nicknamed "Hitler's buzzsaw" by troops of Allies, and alongside the MG 34 it inflicted heavy casualties on Allied soldiers on all European and North African front of World War II. Following the end of the war the victorious Allied nations took interest in the MG 34 and MG 42, influencing many post-war general-purpose machine guns, many of which are still in use today. They lent design elements to the Belgian FN MAG and the American M60, while spawning the Zastava M53, Swiss M51, and Austrian MG 74. Such were its qualities of firepower and usability that it became the foundation of an entire series of postwar machine guns, including the MG 1 and MG 3 - the latter is still in production and service to this day.
