An aircraft cannon is a type of artillery mounted on military aircraft, designed to engage and destroy enemy targets. These cannons can fire a variety of ammunition types, including high-explosive rounds and armor-piercing shells, making them effective against both ground and aerial threats. They are typically integrated into fighter jets and attack aircraft, providing a powerful means of fire support. The use of aircraft cannons dates back to the early 20th century, with notable examples including the M61 Vulcan and the GAU-8 Avenger. These systems are often favored for their high rate of fire and accuracy, allowing pilots to engage targets with precision during combat missions.
