Self-propelled anti-aircraft guns are mobile artillery systems designed to target and destroy enemy aircraft. These weapons combine a powerful gun with a vehicle, allowing them to move quickly on the battlefield. They are equipped with radar and fire control systems to track and engage aerial threats effectively. These systems are often used by military forces to provide air defense for ground troops and critical infrastructure. By being self-propelled, they can reposition rapidly in response to changing threats, enhancing their effectiveness in combat situations. Examples include the ZSU-23-4 Shilka and the M163 Vulcan Air Defense System.
