The '''Gryazev-Shipunov GSh-30-1'''<ref>https://sputniknews.com/russia/201509231027401181-russia-us-cannons/</ref><ref name="urlBorn in the USSR: Russias most vicious Soviet mini-artillery guns - Russia Beyond">{{cite web |url=https://www.rbth.com/science-and-tech/327794-russian-most-vicious-mini-artillery-guns |title=Born in the USSR: Russia's most vicious Soviet mini-artillery guns - Russia Beyond |format= |work= |accessdate=}}</ref> (also known by the GRAU index designation '''9A-4071K''') is a 30&nbsp;mm [[Engineering:Autocannon|autocannon]] designed for use on [[Place:Soviet Union|Soviet]] and later Russian [[Engineering:Military aircraft|military aircraft]], entering service in the early 1980s. Its current manufacturer is the Russian company JSC Izhmash.

==Description==
The GSh-30-1 is a single-barreled, [[Engineering:Recoil operation|recoil operated]] autocannon weighing 46&nbsp;kg (101&nbsp;lb). Unlike many postwar cannons, it uses a short recoil action instead of a [[Engineering:Revolver cannon|revolver cannon]] or Gatling gun mechanism. This results in a reduced [[Rate of fire|rate of fire]], but lower weight and bulk.

The GSh-30-1 has a rate of fire of 1,800 rounds per minute, customarily limited to 1,500 rounds per minute to reduce barrel wear. Despite that, its barrel life is quite short: 2,000 rounds. When firing a continuous burst of 100–150 rounds, the barrel is put under so much stress that it has to be replaced.<ref>{{cite web|url=http://weaponsystems.net/weaponsystem/ii04%20-%20GSh-301.html|title=Gryazev-Shipunov GSh-301 {{!}} Weaponsystems.net|website=weaponsystems.net}}</ref> The gun uses an evaporation cooling system to prevent the detonation of a high explosive round inside a heated barrel. This cooling system consists of a cylindrical water tank around the rear end of the barrel. The GSh-30-1 is equipped with a unique [[Pyrotechnics|pyrotechnic]] mechanism to clear [[Engineering:Firearm malfunction|misfires]]: a small pyrotechnic cartridge is located to the left of the 30mm cartridge chamber. This pyrotechnic cartridge fires a small steel bolt through the side wall of the 30mm cartridge. The hot propellant gases following the bolt into the dud 30mm round ignite the powder charge of that round and firing continues.

The gun's maximum effective range against aerial targets is 200 to 800 m and against surface or ground targets is 1,200 to 1,800 m.

In combination with a [[Physics:Laser|laser]] [[Physics:Laser rangefinder|rangefinding]]/targeting system, it is reported to be extremely accurate as well as powerful, capable of destroying a target with as few as three to five rounds. It has been deployed on several different types of fighter aircraft:

==Ammunition==
The 30x165 mm rounds, fitted with distance-armed and delayed action fuze, are commonly fired from the GSh-30-1. This type of ammunition is intended to engage air and ground targets. The 30x165 mm round can have several projectiles. Its variants are:[http://russianammo.org/Russian_Ammunition_Page_30mm.html] <ref>[http://www.armaco.bg/product/artilery-ammunitions-c15/30x165mm-round-with-hei-projectile-p186/ 30x165 mm Rounds, Armaco JSC  - Bulgaria]</ref>
