The S-250 Chela-class starfighter was a craft used by the Republic fleet at many battles, including the Battle of Rakata Prime
3,956 years before the Battle of Yavin. Though a loser in the "Generation Tomorrow Starfighter" competition, it was still purchased in small numbers by the Republic.
These starfighters were armed with twin laser cannons and missile launchers, and flew alongside the more nimble Aurek fighters in some
battles. Ships of this type were seen leading Republic starfighter squadrons into battle, and often were flown by higher-ranking pilots and squad leaders.
