Uzi submachine gun
|
The Uzi (Hebrew:עוזי, officially cased as UZI) is a related family of submachine guns. Smaller variants are more accurately considered machine pistols.
The first Uzi submachine gun was designed by Uziel Gal in the late 1940s. The prototype was finished in 1950, and initial service issue began in 1954.
Over its service lifetime, the Uzi was manufactured by Israel Military Industries, FN Herstal, and other manufacturers.

Design
Overview
The Uzi uses an open-bolt, blowback-operated design. It and the Czechoslovakian series 23 to 26 were the first weapons to use a "telescoping" ("overhung") bolt design, in which the bolt wraps around the breech end of the barrel (Hogg 1979:157-158). This allows the barrel to be moved far back into the receiver and the magazine to be housed in the pistol grip, allowing for a heavier, slower-firing bolt in a shorter, better-balanced weapon.
The weapon is constructed primarily from stamped sheet metal, making it less expensive per unit to manufacture than an equivalent design machined from forgings. With relatively few moving parts, the Uzi is easy to strip for maintenance or repair. The magazine is housed within the pistol grip, allowing for intuitive and easy reloading in dark or difficult conditions, under the principle of 'hand finds hand'. The pistol grip is fitted with a grip safety, making it difficult to fire accidentally. However, the protruding vertical magazine also makes the gun awkward to fire when prone.
When the gun is decocked, the ejector port closes, preventing entry of dust and dirt. Though the Uzi's stamped-metal receiver is equipped with pressed reinforcement slots to accept accumulated dirt and sand, the weapon can still jam with heavy accumulations of sand in desert combat conditions when not cleaned regularly.
Design drawbacks
The Uzi has been criticized for its open-bolt design. Open bolt, blowback firearms tend to have reduced accuracy, because as the trigger is pulled, the bolt slams forward and hits the breech, interfering with the shooter's aim. Since the bolt is held to the rear when cocked, the receiver is more susceptible to contamination from sand and dirt ingress. The open bolt design does expose the breech end of the barrel, and may improve cooling during periods of continuous fire.
Operational use
|
The Uzi was used as a personal defense weapon by rear-echelon troops, officers, artillery troops and tankers, as well as a frontline weapon by elite light infantry assault forces. The Uzi's compact size and firepower proved instrumental in clearing Syrian bunkers and Jordanian defensive positions during the 1967 Six-Day War. Though the weapon was phased out of frontline IDF service in the 1980s, some Uzis and Uzi variants were still used by a few IDF units until December 2003, when the IDF announced that it was retiring the Uzi from all IDF forces.[2]
In general, the Uzi was a reliable weapon in military service. However, even the Uzi fell victim to extreme conditions of sand and dust. During the Sinai campaign of the Yom Kippur War, IDF army units reaching the Suez reported that of all their small arms, only the 7.62 mm FN MAG machine gun was still in operation.
The Uzi proved especially useful for mechanized troops needing a compact weapon, and for infantry units clearing bunkers and other confined spaces. However, its limited range and accuracy in automatic fire (approximately 50 m) could be disconcerting when encountering enemy forces armed with longer-range small arms, and heavier support weapons could not always substitute for a longer-ranged individual weapon. These failings eventually caused the phaseout of the Uzi from IDF forces.[3]
The Uzi was also used in various conflicts outside Israel and the Middle East during the 1960s and 1970s. Quantities of 9 mm Uzi submachine guns were used by Portuguese cavalry, police, and security forces during the Portuguese Colonial Wars in Africa.
Worldwide arms sales
Total sales of the weapon to date (end 2001) has netted IMI over $2 billion (US), with over 90 countries using the weapons either for their armed forces or in law enforcement.
- The German Bundeswehr used the Uzi since 1959 under the name MP2 (especially for tank crews) and is now changing to the Heckler & Koch MP7.
- The Irish Gardaí Emergency Response Unit (ERU) are replacing the Uzi with the HK MP7.
- In Rhodesia in the late 1970s the Uzi was produced under license, from Israeli-supplied, and later made in Rhodesia, components. It was commonly called the "Rhuzi" (although the title was also applied to some indigenous submachine gun designs).
- Sri Lanka ordered a few thousand Mini Uzi and Uzi Carbines in 1990s. Currently those are deployed with Sri Lanka Army special forces regiment and Sri Lanka Police Special Task Force as their primary weapon when providing security for VIPs.
- The United States Secret Service, the agency that guards the President of the United States, have used the Uzi to provide covering fire while agents evacuated the President out of an area. When President Ronald Reagan was shot on March 30, 1981 outside of the Washington Hilton Hotel by John Hinckley Jr., a Secret Service Special Agent pulled an Uzi out of a briefcase and covered the rear of the presidential limousine as it sped to safety with the wounded president inside.[1]
Variants
- Mini Uzi, Basically a scaled-down version of the Uzi, first introduced in 1980. The Mini Uzi is 600 mm (23.62 inches) long or 360 mm (14.17 inches) long with the stock folded. Its barrel length is 197 mm (7.76 inches) and its muzzle velocity is 375 m/s (1230 f/s).
- Carbine, with a longer 450mm (16 inch) barrel to meet minimum legal rifle overall length requirements for civilian sales in the United States when the stock is folded.
- Micro Uzi, An even further scaled down version of the Uzi, introduced in 1982. The Micro Uzi is 436 mm (19.13 inches) long or 240 mm (9.45 inches) long with the stock folded its barrel length is 134 mm (5.28 inches) and its muzzle velocity is 350 m/s (1148 f/s).
- Micro Uzi Para
- Micro Uzi Pro
- UZI Pistol, a semi-automatic version of the Micro Uzi and does not have a stock.
Recent models of Mini-Uzi and Micro-Uzi are fitted with closed-type bolts.[4]
Caliber variants
Most Uzis fire the 9x19mm Parabellum cartridge, though some fire .22 LR, .41 AE, or .45 ACP. Caliber conversions exist in .40 S&W and 10 mm auto [2].
Available magazines include 20-, 25-, 32-, 40-, and 50-round magazines (9x19mm Parabellum), 10-round magazines (.41 and .22 LR), and 16-round magazines (.45 ACP). All of the above are manufactured by IMI. Other high-capacity magazines exist (e.g. 50-round magazines and 100-round drums in 9 mm) which are manufactured by companies such as Vector Arms.

In popular culture
The Uzi and its variants are some of the most popular submachine guns in the world. Along with the MP5 and MAC-10, they have appeared in many films, TV series, and video games.
As the Uzi is designed to be used in one hand if its user loses the use of a hand in battle, fictional characters and videogame characters are sometimes shown firing two Uzis, one in each hand.
