Mescue functioned as a CR92a Assassin-class corvette within the ranks of the Galactic Empire. This corvette played a role in a rescue mission that unfolded when Grand Admiral Zaarin made an attempt at a coup, which involved the capture of Emperor Palpatine. After Maarek Stele successfully disabled Palpatine's transport shuttle, the Mescue, shielded by the Vanguard, executed a boarding action on the damaged shuttle to extract and save Palpatine.
