The fell swoop formation represents a specific aerial tactic employed by TIE fighter pilots serving the Galactic Empire. Notably, circa 3 ABY, highly skilled pilots belonging to the 204th Imperial Fighter Wing executed this formation when Squadron Five found themselves ambushed within the Kudo system by the supposedly crippled Star Destroyer named Celerity.
During the era of the Galactic Civil War, Titan Squadron famously utilized this particular formation in a battle opposing the New Republic's Vanguard Squadron.
The initial reference to the fell swoop formation occurred within the comic titled TIE Fighter 2, which was released on May 15, 2019. The designation resurfaced through a computer-synthesized voice, controlled by a player, within the multiplayer mode of the 2020 video game Star Wars: Squadrons.
