Anti-aircraft warfare

Anti-aircraft warfare, or air defence, is any method of engaging military aircraft in combat from the ground. Various guns and cannons have been used in this role since the first military aircraft were used in World War I, growing in power and accuracy over the years. Starting in the post-World War II era, the guns were joined by the guided missile, specifically the "surface-to-air missile", and today both are used in combination in most roles.
