Aerial ramming or air ramming is the ramming of one aircraft with another. It is a last-ditch tactic in air combat, sometimes used when all else has failed. Long before the invention of aircraft, ramming tactics in naval warfare and ground warfare were common. The first aerial ramming was performed by Pyotr Nesterov in 1914 during the First World War. In the early stages of World War II the tactic was employed by Soviet pilots, who called it taran, the Russian word for "battering ram".
