The A-10 Thunderbolt II is a United States Air Force close-air-support aircraft commonly nicknamed the Warthog. Its distinctive sound is closely associated with the aircraft's nose-mounted GAU-8/A Avenger rotary cannon, which produces a dense, buzzing report during a burst. The aircraft entered service in the 1970s and later became a familiar subject in military footage, games, documentaries, and online memes. Recordings and recreations of its cannon noise remain popular because the delayed, mechanical roar is instantly dramatic and easily matched with action scenes.
