Gatling in and patented in The Gatling gun was a field weapon, first used in warfare during the American Civil War and subsequently by European and Russian armies. The design was steadily improved; by the Gatling gun had a theoretical rate of fire of 1, rounds per minute, although rounds per minute was more readily achievable in combat.
By , the M Gatling gun was capable of a maximum rate of fire of some — rounds per minute. Ultimately the Gatling's weight and cumbersome artillery carriage hindered its ability to keep up with infantry forces over difficult ground and was superseded by lighter and more mobile machine-guns. All models of Gatling guns were declared obsolete by the U. Army in , after 45 years of service.
After the Gatling gun was replaced in service by newer recoil- or gas-operated non-rotating machine guns, the approach of using multiple rotating barrels fell into disuse for many decades.
However, some examples were developed during the interwar years but only existed as prototypes, or rarely used. Army Air Force determined that an automatic cannon of improved design with an extremely high rate of fire was required to achieve a sufficient number of large-caliber hits on fast-moving enemy jet aircraft. Using experience gained from 20mm and 30mm cannon utilized by Luftwaffe aircraft, a larger-caliber cannon shell for the new gun was deemed desirable, as it contained room for an explosive with more destructive force than the.
While researching prior work, ordnance engineers recalled the experimental electrically driven Gatling weapons of the turn of the 20th century. In , a Model Gatling gun borrowed from a museum was set up with an electric motor drive and test-fired by General Electric engineers.
The year-old design briefly managed a rate of fire of 5, rounds per minute. In General Electric began testing the first model of its modified Gatling design, now called the Vulcan Gun. The first prototype was designated the T45 Model A. It fired. In , GE delivered ten initial model A. T45 guns for evaluation. Thirty-three model C T45 guns were delivered in in three calibers:.
After extensive testing, the T 20mm gun was selected for further development. In , the T 20mm gun was standardized by the U. Army and U. Air Force as the M61 20mm Vulcan aircraft gun.
Special Warfare combatant-craft crewmen use a Gatling gun to lay down suppressing fire during a practice "hot" extraction of forces on a beach. One of the main reasons for the resurgence of the electrically or hydraulically powered multiple-barrel design is the weapon's tolerance for continuous high rates of fire. For example, rounds per minute of continuous fire from a conventional single-barrel weapon ordinarily results in rapid barrel heating followed by stoppages caused by overheating.
In contrast, a five-barreled machine gun firing rounds per minute fires only rounds per barrel per minute, an acceptable rate of fire for continuous use. The only limiting factor is the rate at which loading and extraction can occur.
It was also a time of great technological change. Inventors and military men devised new types of weapons, such as the repeating rifle and the submarine, that forever changed the way that wars were fought. With each passing day, the debate for or against gun control rages on within the United States.
And although the National Rifle Association NRA currently leads the charge for the rights of citizens to carry guns of all types with little to no interference from the government, Fort Sumter is an island fortification located in Charleston Harbor, South Carolina most famous for being the site of the first shots of the Civil War Originally constructed in as a coastal garrison, U.

This Day In History. History Vault. Who Was Richard Jordan Gatling? So those don't have a "spin-up" time since there's nothing there to rotary the barrels without firing bulats.

Hello, This is something I've been looking for a lot of time and have not found any reliable information, on how Gatling guns work Hollywood and video games portray it needing some time to spin up before shooting; the barrels first spin and, after a certain RPM is achieved, it then starts firing.
The spin up is needed because the barrel spin speed needs to match the loading speed otherwise you run the risk of the bullets being fired into the gun assembly instead of out of the barrels.

I think you hit the nail on the head when you said Holywood. WindSplitter1, on 28 August - AM, said: Yes, this is why I think it doesn't make sense for a Gatling gun to spin up first and then shoot, outside shooting the first rounds in each barrel. It would shoot while spinning, ergo, do both at the same time. But is it one or the other? One can hold fire while the gun barrels are spinning? No, right? WindSplitter1, on 27 August - PM, said: It would shoot while spinning, ergo, do both at the same time.
A gatling gun works by rotating the crank which in turn starts rotating the barrels. Imagine it a bit like having the safety off.
