MILITARY GAU 19B 50 CAL GATLING GUN


Another great weapon for the US military and us army. Could prove useful in combating terrorists in Iraq and Syria. The GECAL 50, officially designated by the United States military as the GAU-19/A, is an electrically driven Gatling gun that fires the .50 BMG (12.7×99mm) cartridge.

Technical specifications

The GAU-19/A is designed for a linkless feed, but can be fed from a standard M9 linked belt if a delinker feeder is used. The rate of fire is selectable to be either 1,000 or 2,000 rounds per minute. The Humvee armament kit version fires at 1,300 rounds per minute. The average recoil force when firing is 500 pounds-force (2.2 kN). In January 2012, General Dynamics announced they would be delivering a new version designated the GAU-19/B. It provides the same firepower in a lighter platform, weighing 106 lbs.[1]

History

The GECAL 50 was first manufactured by General Electric, then by Lockheed Martin, and now by General Dynamics. Design work began in 1982. Early prototypes had six barrels, but a three-barreled configuration is now standard. The GAU-19/A was originally designed as a larger, more potent version of the M134 Minigun. Due to the loss of nine helicopters in Grenada GE started building prototypes of the weapon in both a three-barreled and a six-barreled configuration. The six-barreled version was designed to fire 4,000 rpm, and could be adapted to fire up to 8,000 rpm. The GAU-19 takes 0.4 seconds to reach maximum firing rate.[2] Soon it was recommended as a potential armament for the V-22 Osprey.[3] The magazine would be located underneath the cabin floor and could be reloaded in-flight. However, plans to mount the gun were later dropped.[4] In 2005, the GAU-19/A was approved to be mounted on the OH-58D Kiowa helicopter. It also could have been used on the Army's now cancelled ARH-70.[5] In January 2012, the U.S. Army ordered 24 GAU-19/B versions for use on helicopters. All were delivered by the next month.[1]
In 1999, the United States sent 28 GAU-19s to Colombia. Oman is known to use the GAU-19/A mounted on their HMMWVs. The navy of Mexico uses MDH MD-902 series helicopters with the GAU-19/A system mounted for anti-narcotics operations.

Gatling Gun History

The Gatling gun is one of the best-known early rapid-fire weapons and a forerunner of the modern machine gun. Invented by Richard Gatling, it is known for its use by the Union forces during the American Civil War in the 1860s, which was the first time it was employed in combat. Later it was used in the Boshin War, the Anglo-Zulu War and still later in the assault on San Juan Hill during the Spanish-American War.

The Gatling gun's operation centered on a cyclic multi-barrel design which facilitated cooling and synchronized the firing/reloading sequence. Each barrel fired a single shot when it reached a certain point in the cycle, after which it ejected the spent cartridge, loaded a new round, and in the process, allowed the barrel to cool somewhat. This configuration allowed higher rates of fire to be achieved without the barrel overheating.

History

Patent drawing for R.J. Gatling's Battery Gun, 9 May 1865.

The Gatling gun was designed by the American inventor Dr. Richard J. Gatling in 1861 and patented on November 4, 1862. Gatling wrote that he created it to reduce the size of armies and so reduce the number of deaths by combat and disease, and to show how futile war is.
Although the first Gatling gun was capable of firing continuously, it required a person to crank it; therefore it was not a true automatic weapon. The Maxim gun, invented in 1884, was the first true fully automatic weapon, making use of the fired projectile's recoil force to reload the weapon. Nonetheless, the Gatling gun represented a huge leap in firearm technology.

Prior to the Gatling gun, the only weapons available to militaries capable of firing many projectiles in a short space of time were mass-firing volley weapons like the French Reffye mitrailleuse in 1870–1871, or field cannons firing canister, much like a very large shotgun. The latter were widely used during and after the Napoleonic Wars. Although the maximum rate of fire was increased by firing multiple projectiles simultaneously, these weapons still needed to be reloaded after each discharge, which for multi-barrel systems like the mitrailleuse was cumbersome and time-consuming. This negated much of the advantage of their high rate of fire per discharge, making them much less powerful on the battlefield. In comparison, the Gatling gun offered a rapid and continuous rate of fire without having to manually reload by opening the breech.

Soyuz launcher puts Russian military spy satellite in orbit

A Russian military spacecraft with a high-resolution digital mapping camera is in orbit Thursday after a successful ascent aboard a Soyuz rocket.

The Soyuz-2.1a rocket lifted off at 0942 GMT (5:42 a.m. EDT; 12:42 p.m. local time) from the Plesetsk Cosmodrome in northern Russia, a military spaceport about 500 miles (800 kilometers) north of Moscow, according to a statement released by the Russian Ministry of Defense.

The launch went normally, Russian defense officials said, and the rocket deployed its secretive payload in orbit less than 10 minutes after liftoff.

U.S. tracking data show two objects attributed to Thursday’s flight — the Soyuz rocket’s third stage and the Russian military satellite — in an orbit with a low point of around 201 miles (324 kilometers) and a high point of around 333 miles (536 kilometers) with an inclination of 97.6 degrees to Earth’s equator.

The satellite lofted Thursday is believed to be Russia’s second spacecraft in the Bars-M series of sharp-eyed optical reconnaissance platforms.



The first member of the Bars-M series launched in February 2015 from the same launch pad at Plesetsk, and aboard the same type of Soyuz booster, which features a modernized digital flight control system to replace analog guidance employed aboard earlier versions of Russia’s workhorse rocket.

Made by TsSKB Progress in Samara, Russia, the Bars-M satellite’s capabilities are classified, but analysts believe it hosts a digital imager, replacing older satellites that carried film cameras that returned to Earth via parachute to be recovered and developed.

The Bars-M satellite’s Karat electro-optical camera was developed by the Leningrad Optical Mechanical Association, and the satellite is expected to operate at least five years, according to documents posted on a Russian government procurement website.

The upgrade allows the Bars-M satellites to remain in orbit longer and send imagery to analysts via radio links.

The last of the old-generation satellites launched in 2005, leaving Russia with a gap in the imaging capability to be filled by Bars-M, which specializes in collecting stereo images to help create maps for use by the Russian military.

The Russian Defense Ministry said Thursday that the new satellite received the designation Kosmos 2515, keeping with the military’s naming scheme for defense-related spacecraft.

The Kosmos 2515 satellite is functioning normally after Thursday’s launch, and ground controllers are in contact with the spacecraft, the defense ministry reported on its website.
