The Yakushev-Borzov YakB-12.7 mm is a remotely controlled 12.7×108mm caliber four-barrel rotary cannon developed by the Soviet Union in 1973 for the Mil Mi-24 attack gunship and low-capacity troop transporter, with 1470 rounds, which can also be mounted in GUV-8700 machine-gun pods with 750 rounds. It has a high rate of fire (4–5,000 rounds per minute) and is also one of the few self-powered guns of the Gatling type (i.e. it is gas-operated, rather than requiring an external motor to operate).
On the Mi-24 it is mounted in the VSPU-24 undernose turret, with an azimuth of 60° to either side, an elevation of 20°, and a depression of 60°. The gun is slaved to the KPS-53AV undernose sighting system with a reflector sight in the front cockpit.
It was replaced by the fixed, side-mounted GSh-30K or the swivel-mounted GSh-23L in the late mark of the Mi-24 helicopters, as it did not provide enough firepower against dug-in or lightly armored targets that did not necessitate a rocket attackbut it is still used on Mil Mi-24, Mil Mi-36, and Mil Mi-40 helicopters.
The M61 Vulcan is a hydraulically, electrically or pneumatically driven, six-barrel, air-cooled, electrically fired Gatling-style rotary cannon which fires 20 mm rounds at an extremely high rate. The M61 and its derivatives have been the principal cannon armament of United States military fixed-wing aircraft for sixty years.
A gunship is a military aircraft armed with heavy guns, primarily intended for attacking ground targets.
The Mil Mi-24 is a large helicopter gunship, attack helicopter and low-capacity troop transport with room for eight passengers. It is produced by Mil Moscow Helicopter Plant and has been operated since 1972 by the Soviet Air Force and its successors, along with 48 other nations.
The General Dynamics GAU-12/U Equalizer is a five-barrel 25 mm Gatling-type rotary cannon. The GAU-12/U is used by the United States, Italy and Spain, which mount the weapon in their attack jets such as the AV-8B Harrier II, airborne gunships such as the Lockheed AC-130, and land-based fighting vehicles. A lighter four-barrel version, designated GAU-22/A, is mounted on F-35 Lightning II fighter jets.
The M134 Minigun is a 7.62×51mm NATO six-barrel rotary machine gun with a high rate of fire. It features a Gatling-style rotating barrel assembly with an external power source, normally an electric motor. The "Mini" in the name is in comparison to larger-caliber designs that use a rotary barrel design, such as General Electric's earlier 20 mm M61 Vulcan, and "gun" for the use of rifle ammunition as opposed to autocannon shells.
The Gryazev-Shipunov GSh-6-23 is a six-barreled 23 mm rotary cannon used by some modern Soviet/Russian military aircraft.
The Nudelman-Rikhter NR-23 is a Soviet autocannon widely used in military aircraft of the Soviet Union and Warsaw Pact. It was designed by A. E. Nudelman and A. A. Rikhter to replace the wartime Nudelman-Suranov NS-23 and Volkov-Yartsev VYa-23, entering service in 1949.
The Gryazev-Shipunov GSh-23 ) is a twin-barreled 23 mm autocannon developed in the Soviet Union, primarily for military aircraft use. It entered service in 1965, replacing the earlier Nudelman-Rikhter NR-23 cannon.
The Gryazev-Shipunov GSh-30-2 (ГШ-30-2) or GSh-2-30 is a Soviet dual-barrel autocannon developed for use on certain ground attack military aircraft and helicopters.
The Gryazev-Shipunov GSh-6-30 is a Russian 30 mm rotary cannon aircraft-mounted and naval autocannon used by Soviet and later CIS military aircraft. The GSh-6-30 fires a 30×165mm, 390 g projectile.
A gun pod is a detachable pod or pack containing machine guns, autocannons or rotary cannons and ancillaries, mounted externally on a vehicle such as a military aircraft which may or may not also have its own guns.
A rotary cannon, rotary autocannon, rotary gun or Gatling cannon, is any large-caliber multiple-barreled automatic firearm that uses in a Gatling-type rotating barrel assembly to deliver a sustained saturational direct fire at much greater rates of fire than single-barreled autocannons of the same caliber. The loading, firing and ejection functions are performed simultaneously in different barrels as the whole assembly rotates, and the rotation also permits the barrels some time to cool. The rotating barrels on nearly all modern Gatling-type guns are powered by an external force such as an electric motor, although internally powered gas-operated versions have also been developed.
The XM214 is an American prototype 5.56 mm rotary-barreled machine gun. It was designed and built by General Electric. Also known as Microgun, the XM214 was a scaled-down smaller and lighter version of the M134 minigun, firing M193 5.56×45mm ammunition.
The ShVAK was a 20 mm autocannon used by the Soviet Union during World War II. It was designed by Boris Shpitalniy and Semyon Vladimirov and entered production in 1936. ShVAK were installed in many models of Soviet aircraft. The TNSh was a version of the gun produced for light tanks.
The GAU-19/A is an electrically-driven, three-barrel rotary heavy machine gun that fires the .50 BMG (12.7×99mm) cartridge.
The Glagolev-Shipunov-GryazevGShG-7.62 is four-barreled rotary machine gun designed in the Soviet Union, similar to firearms such as the M134 Minigun. It is a gas operated, self-powered weapon, which is in contrast with most other rotary guns. It was developed in 1968–1970 for the Mi-24 helicopter together with YakB 12.7mm machine gun, and is currently used in GUV-8700 gun pods, and flexible mounts on Kamov Ka-29.
The 23×115mm round is used by Soviet (USSR)/Russian/CIS aircraft autocannon, most notably by the GSh-23L and GSh-6-23. Although the round has been superseded by the 30×165mm round, the Russian Air Force still uses it in the GSh-23L and GSh-6-23. This round still serves in many countries and is widely available. Projectile weight is 175 grams.
The Afanasev A-12.7 is a heavy machine gun developed by Nikolay M. Afanasev in 1949 and adopted for service in 1953. This gun was supposed to have a considerably higher rate of fire than its predecessor, the Berezin UB aircraft machine gun. Due to excessive barrel wear however, it was eventually limited by an electrical trigger to a rate comparable to the Berezin UB. Initially intended to be mounted in the defensive turrets of the Tu-4 bomber, the A-12.7 was ultimately installed only in trainer aircraft and helicopters. Nevertheless, it was produced for 30 years.
The Gryazev-Shipunov GSh-30-1 is a 30 mm autocannon designed for use on Soviet and later Russian military aircraft, entering service in the early 1980s. Its current manufacturer is the Russian company JSC Izhmash.
