The American A-10 Thunderbolt II attack aircraft carries a seven-barreled GAU-8 / A Avenger aircraft gun (translated from English as “avenger”).  The GAU-8/A turns the old attack aircraft into a powerful weapon, writes 19FortyFive.
It is stated that the Avenger weapon is designed to destroy ground equipment.  The GAU-8/A was developed to fight Soviet-made tanks during the Cold War.  The weapon is used on aircraft and ships of the US Navy.
The maximum rate of fire of a hydraulically driven gun is 4200 rounds per minute.  The weapon uses high-explosive fragmentation and armor-piercing projectiles from depleted uranium.  It is estimated that one volley of GAU-8 / A can hit up to 40 targets.  80 percent of projectiles fired can hit a circle with a radius of 6.1 meters.
