The E-11 is a fictional blaster rifle carried by Imperial stormtroopers throughout the Star Wars franchise, beginning with the original 1977 film. Its compact black design became one of the series’ most recognizable weapons. Star Wars sound designer Ben Burtt created the franchise’s signature blaster effects by striking the guy wires of a radio tower, producing their distinctive metallic energy snap. Short clips modeled on that sound later spread through fan films, edits, games, and memes, often alongside a simpler pew-pew sound effect for comic contrast.
