The recognizable “brrrt” is associated with the Fairchild Republic A-10 Thunderbolt II and its GAU-8/A Avenger 30 mm rotary cannon. The aircraft was designed around this weapon for close air support and entered United States Air Force service in the 1970s. Rapid firing makes individual reports merge into one abrasive buzz. Recordings and imitations later spread through aviation communities, military videos, games and image macros, where the sound became shorthand for the A-10’s formidable firepower. It remains popular because listeners can identify it almost immediately.
