The US revealed how the gun fired 3,900 rounds / minute to fire

The US Air Force has released for the first time detailed images of how the GAU-8 Avenger super-fast gun fired on the A-10 ground attack.
According to Aviationist, the GAU-8 Avenger, or GAU-8 for short, is a 30mm (7-barrel) multi-barrel automatic cannon model, used mainly by the US Air Force on A- attack tanks. 10 – and is the main factor creating the terrible attack ability for this fighter.

Born in 1977, GAU-8 up to now basically has not had much difference compared to its inception. This cannon weighs 281 kg and has a total length of up to … 6.06 meters in which the barrel is 2.3 meters long. The GAU-8 over the A-10. The cannon used the caliber 30x173mm and had a total of 7 barrels. Due to the use of an electric reload mechanism, this cannon had a very small recoil and could even be considered non-recoil with the post escape mechanism. The maximum rate of fire of the cannon was up to 3900 rounds / min. At this rate of fire, no one could even hear every bullet coming out of the barrel of the GAU-8 cannon and only heard a very fast “crack” sound. With a barrel length of more than 2 meters, the barrel head speed of the bullet was pushed by GAU-8 at speeds of up to 1000 meters per second. This muzzle-tip is faster than the speed of sound and is essentially the target of the GAU-8 that will not hear anything before being hit by bullets. The effective range of this cannon was 1200m but its maximum range could be up to 3600m depending on combat conditions. Previously, the GAU-8 even changed the rate of fire from the lowest speed of 2100 rounds / min to the highest speed of 4200 rounds / min. However, later, the engineers of the US Air Force realized that not many pilots paid attention to the GAU-8’s variable rate of fire, so they removed this feature, greatly reducing electronic systems. like complex mechanics. The accuracy of the GAU-8 can be considered to be absolute, much better than its predecessor M61 Vulcan (still equipped on the more advanced F-15) that fought in Vietnam. At maximum distance, over 80% of the ammunition of the GAU-8 fired in the test was accurate. Although the ammunition is only 30mm, one thing for sure is that this cannon can defeat many main battle tanks. Even without penetrating the tank’s explosive armor, the GAU-8’s 30mm bullets are capable of severely damaging the tank’s electronic sensors, rendering it impotent. continue to fight. Reloading the GAU-8 is quite heavy and often requires the help of heavy machinery. On the attack A-10, for example, it can carry only 1,174 30mm bullets for the GAU-8 – meaning it can only shoot for about 20 seconds … clean bullets. But in addition to the amount of ammunition for the GAU-8, this fighter can also carry nearly all of the missiles and bombs in the US Air Force, making the A-10 a worthwhile air attack machine. afraid of all targets.
