Gray Seven signified the identifier for the seventh member within either the Rebel Alliance's Gray Flight or the New Republic's Gray Squadron, identified by the call sign. The utilization of this designation across both groups meant that the call sign Gray Seven was adopted by several pilots of starfighters.
Following the Battle of Yavin, Prithi, a Rebel pilot, piloted an X-wing starfighter under the Gray Seven identifier within Leia Organa's secret squadron.
Before the squadron's eventual naming as Wraith Squadron, Ton Phanan held the position of the seventh member in the New Republic's Gray Squadron, using the Gray Seven designation.
