Wing 4 represented the designation for a Republic troopship specialized in rocket-jumper deployment, active throughout the Freedon Nadd Uprising.
In 3998 BBY, Wing 4 was responsible for transporting Republic rocket-jumpers onto the battlefields of Onderon, at a time when the Republic dispatched a naval force to support the Jedi detachment under siege.
The rocket-troopers it carried landed in proximity to the Krath Enchanter.
