Guns
The dual 2A38 30 mm cannons and the later 2A38M were designed by the KBP Instrument Design Bureau and manufactured by the Tulamashzavod Joint Stock Company. The cannons are fired alternatively with a combined rate of fire of between 3,900 and 5,000 rounds per minute (1,950 to 2,500 rpm for each gun), and have a muzzle velocity of 960 m/s. Bursts of between 83 and 250 rounds are fired as determined by the target type, with an engagement range between 0.2 and 4.0 km and to an altitude of 4 km. HE-T and HE-I shells are used and fitted with a A-670 time and impact fuze which includes an arming delay and self destruct mechanism. The cannons can be elevated and depressed to +87 to −10 degrees and as such can be used to engage ground as well as aerial targets. The 2K22 can fire its cannons in two primary modes of operation, radar and optical, in radar mode the target tracking is fully automatic, with the guns aimed using data from the radar. In optical mode the gunner tracks the target through the 1A29 stabilized sight, with the radar providing range data. The 9K22 is reported to have a kill probability of 0.8 with cannon.

Famous quotes containing the word guns:
“After a shooting spree, they always want to take the guns away from the people who didn’t do it. I sure as hell wouldn’t want to live in a society where the only people allowed guns are the police and the military.”
—William Burroughs (b. 1914)
“The parents who wish to lead a quiet life I would say: Tell your children that they are very naughty—much naughtier than most children; point to the young people of some acquaintances as models of perfection, and impress your own children with a deep sense of their own inferiority. You carry so many more guns than they do that they cannot fight you. This is called moral influence and it will enable you to bounce them as much as you please.”
—Samuel Butler (1835–1902)
