The 30 mm 2A42 autocannon was developed as a replacement for The 2A42 fires 30×165 ammunition, a cartridge introduced in the 1970s in the Soviet Union to replace previous 30 mm autocannon cartridges. Other weapons using this size of cartridge case include the 2A38 and 2A72 autocannons for various vehicle, helicopter and air defence applications, as well as numerous single-, dual- and six-barrel naval and air force cannons. The gunner can select one of two rates of full automatic fire, low at 200 to 300 rds/min and high at 550 to 800 rds/min. the 2A42 has a rate of fire off up to 200 to 300 rpm (low) and 550 rpm on high. The design bureau for the 30 mm 2A42 cannon is the KBP Instrument Design Bureau. Land Forces Weapons, export catalogue, Rosoboronexport. Soviet Union Soviet Union Autocannon The gunner can select one of two rates of full automatic fire, low at 200 to 300 rds/min and high at 550 to 800 rds/min. High Explosive (HE) ammunition is often used to maximize damage against armored targets. According to the manufacturer, effective range when engaging ground targets such as light armoured vehicles is 1,500 m while soft-skinned targets can be engaged out to 4,000 m. Air targets can be engaged flying at low altitudes of up to 2,0 For the T-80 was created and tested the installation with a 30-mm automatic cannon 2A42. The 2A42, 2A38 and 2A72 fire percussion-primed ammunition; the naval and aerial cannons use electrical priming, and therefore their ammunition is not interchangeable with the land-based ammunition types, despite the same cartridge case size.Originally three basic types of ammunition were developed in the Soviet Union for the land-based weapons: high explosive incendiary, high explosive fragmentation with tracer, and an armour-piercing ballistic capped with tracer.

Accuracy and consistency; The propping elements of the barrel contribute to high accuracy and consistency. A small number of these have now entered service. It was developed as a less complex and lighter alternative to the widely used 2A42. The 30 mm 2A42 cannon has a dual feed. The 2A42 30mm cannon is a dual feed 30mm cannon created for the Russian army. The 2A42, 2A38 and 2A72 fire percussion-primed ammunition; the naval … Entered service -
