Anti-aircraft guns are artillery weapons designed to target and destroy enemy aircraft. They use high-velocity projectiles to hit fast-moving aerial targets, often employing radar or optical sights for aiming. These guns can vary in size and caliber, ranging from smaller, portable models to larger, fixed installations. Historically, anti-aircraft guns played a crucial role during conflicts such as World War II, where they were used to defend against enemy bombers and fighter planes. Modern versions have evolved to include automated systems and advanced targeting technology, enhancing their effectiveness in protecting ground forces and strategic locations from aerial threats.
