The B28 Extinction-class bomber, also referred to as the B-28 or Vanguard starfighter, was a starfighter class used by the reconstituted Sith Empire in the Great Galactic War and during the Cold War. The bomber saw extensive use during the Sacking of Coruscant, wherein squadrons of the vessel devastated much of the Coruscant
cityscape. During the Cold War, the Keizar-Volvec bulk cruiser Paramount carried several B-28s and used them to bombard the planet Sebaddon during Independent Operation Sebaddon in 3643 BBY.
