2A42 is a 30 mm automatic cannon from the Cold War period and modern times, initially Soviet, and now Russian. The first prototypes of this weapon were made around 1970, but it entered mass production and service in the Soviet Army in 1980. The total weight of the weapon is 115 kilograms, and the barrel length is 2.416 meters. The maximum theoretical rate of fire of the 2A42 cannon is from 550 to 800 rounds per minute, and the average initial velocity obtained by a bullet fired from this weapon is 960 m / s. The maximum range of the 2A42 is 4,000 meters, and the effective range of the shot ranges from 1,500 to 2,000 meters. The presented cannon was developed by a team led by Arkady Szypunov, and the production plant in Tula (Tulamashzavod) was responsible for its production. The gun was developed to replace the 76 mm gun line 2A28 Grom, and its main purpose was to counter armored targets and enemy manpower. The plot 2A42, compared to its predecessor, is a completely new design with a different caliber of weapons, a much higher rate of fire, but also a high firepower for this class of cannon. The 2A42 cannon is the primary weapon of such vehicles as the BMP-2, BMPT Terminator or BTR-90, but it is also used on the Mil Mi-28 helicopter.
AGS-17 Flame is a 30 mm automatic grenade launcher from the Cold War period and modern times of Soviet and now Russian production. The first prototypes of the weapon were made in 1969, and production started in 1971 and is still ongoing. The total mass of the grenade launcher is 35 kilograms, with a total length of 84 centimeters (the length of the barrel is 29 centimeters). The initial velocity of the projectile fired from this weapon is 185 m / s, and the practical rate of fire ranges from 60 to 70 rounds per minute. The effective range of the shot is up to 1700 meters. The presented grenade launcher was developed by a team led by A. Nudelaman in the OKB-16 design office. The grenade launcher was and is intended primarily to combat enemy manpower, as well as small surface targets. The weapon is powered by ammunition belts of up to 29 rounds. Due to the good ballistic properties of the weapon, as well as the relatively high degree of reliability AGS-17 Płomień is still in production in Russia and the PRC. It is also very often used as an armament for vehicles such as the BMPT Terminator, but also for Mil Mi-24 and Mil Mi-8 helicopters.
