Screamer Squadron emerged as one of numerous combatant groups established amidst the New Republic's resurgence throughout the Yuuzhan Vong War. This squadron was equipped with X-wing starfighters.
Given that a substantial number of seasoned New Republic pilots suffered fatalities or severe wounds in the war's initial stages, a considerable deficit arose in qualified leaders for the newly formed units, exemplified by Barefoot Squadron, commanded by a sixteen-year-old Jedi Knight. Screamer Squadron faced a similar predicament, headed by a pilot of merely twenty-three years, far from being a seasoned combatant.
Screamer Squadron, piloting X-wing starfighters, participated in the ill-fated operation targeting the Peace Brigade administration governing the Ylesia system.
