When General Crix Madine and several Sullustan technicians planned to end Operation Strike Fear by destroying its command ship, the Imperial-class Star Destroyer Invincible, Lightning was dispatched to capture some technicians from Cygnus Corp during a test of their new spacecraft, the Alpha-class Xg-1 Star Wing.
Keyan Farlander and Sunnar Jan-lo identified the transport carrying the Cygnus staff and then fought off Imperial fighters while the Lightning conducted a boarding operation.
Later the Cygnus techs were 'convinced' to aid the Alliance in destroying the Invincible by modifying a Lambda-class T-4a shuttle to plant a stolen warhead on the Star Destroyer.
Lightning also assisted in the capture of Imperial Overlord Ghorin's Y-wings during Operation Grain Snatch.
