The Borleenan TIE bomber was manufactured only on the planet Borleen by Excor Industries. It was designed by Althur Grell and Goroth Rall with the blessing of Sienar Fleet Systems who at the time thought it wise to outsource premium regional TIE variants to local manufacturers. It was believed that by the time of the New Jedi Order that all Borleenan TIE bombers had been retired in favor of the newer Scimitar assault bombers.
