Design

The 30 mm 2A42 autocannon was developed as a replacement for 2A28 Grom and has a dual feed. One is for HE-T and the other for AP-T rounds. 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. [4] 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 2,000 m at subsonic speeds and up to a slant range of 2,500 m. [5] In addition to being installed in a two-person turret on the BMP-2 mechanised infantry combat vehicle, this gun is also fitted in the BMD-2 airborne combat vehicle, BMD-3 airborne combat vehicle and BTR-90 (or GAZ-5923) (8 × 8) armoured personnel carrier. A small number of these have now entered service. More recently, the 30 mm 2A42 cannon has been installed in a new turret and fitted onto the roof of the BTR-T heavy armoured personnel carrier based on a modified T-54/T-55 MBT chassis. The cannon is also the main armament of BMPT (Tank Support Fighting Vehicle). It is also used for various armament projects from various manufacturers. The design bureau for the 30 mm 2A42 cannon is the KBP Instrument Design Bureau.

The 2A42 autocannon has also been used on the BMPT and Bumerang-BM, and on unmanned remote controlled weapon station turrets on the new Russian infantry fighting vehicles, Kurganets-25, VPK-7829 Bumerang. and T-15 Armata.

Variants

Ammunition

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, 2A38M, 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 2A42, 2A38, 2A38M, 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. [7] [8]

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. Later a sub-caliber armour-piercing round was introduced, and today also countries other than Soviet Union/Russia manufacture 30 x 165 percussion-primed ammunition. The main types of ammunition are summarized in the table below:

DesignationTypeProjectile weight (g)Bursting charge (g)Muzzle velocity (m/s)Notes
3UOF8HEI389 [9] 49 g [9] 960 [9] A high-explosive incendiary round with A-670M nose fuze. [10] The fuze produces a 0.15 millisecond delay on impact, and a self-destruct mechanism detonating the projectile after 7.5 to 14.5 seconds of flight (3900–5300 m distance from muzzle). [7]
3UOR6HE-T385 [9] 11.5 g [9] 960 [9] Nose-fuzed high-explosive fragmentation tracer round, utilizing the same A-670M impact/self-destruct fuze as the 3UOF8. [10] Tracer burn time 10 to 14 seconds.

18mm thick plate at 60 degree impact, 1500 m range [11]

Airburst munitions for Russian 30mm and 57mm autocannons are in development. [13] [14] [15] [16] [17]

The autocannon has been used since the 1980s on the following platforms:

Infantry fighting vehicles
MRAPs
Unmanned ground vehicles
Attack helicopters

Similar 30mm autocannons

The 2A72 30mm autocannon, designed by KBP Instrument Design Bureau, is a lighter, less complex cousin of the 2A42, with a longer barrel. While the latter has 578 parts, 2A72 has only 349 parts, allowing it to weigh only 84 kg (with 36 kg barrel). 2A72 use long recoil principle, resulted in lower recoil (7t instead of 20), but lower rate of fire (300-330 instead of 550). 2A72 is used in:

The 2A38 and 2A38M are 30mm twin-barrel autocannons, Gast-type. They are mainly used on air defense vehicles like 2K22 Tunguska and Pantsir-S1. It weighs 195 kg and has a maximum rate of fire of 2500 rd/min.

The Ordnance Factory Medak in India has developed the Medak gun and CRN 91 Naval Gun out of this platform.

Infantry fighting vehicle Type of armored personnel carrier with direct-fire support

An infantry fighting vehicle (IFV), also known as a mechanized infantry combat vehicle (MICV), is a type of armoured fighting vehicle used to carry infantry into battle and provide direct-fire support. The 1990 Treaty on Conventional Armed Forces in Europe defines an infantry fighting vehicle as "an armoured combat vehicle which is designed and equipped primarily to transport a combat infantry squad, and which is armed with an integral or organic cannon of at least 20 millimeters calibre and sometimes an antitank missile launcher". IFVs often serve both as the principal weapons system and as the mode of transport for a mechanized infantry unit.
