The four hundred and thirty-ninth bomber wing provided service to the Republic Navy. Prior to her role as Supreme Chancellor of the Galactic Republic, Galena Rans held the rank of commander within the four hundred and thirty-ninth bomber wing. Rans stated in 3627 BBY that since her service with the four hundred and thirty-ninth bomber wing, she hadn't participated in a military briefing comparable to Fleet Admiral [Numinn]'s before the reconstituted Sith Empire's assault on the Meridian Complex of the planet Corellia.
The 2019 Onslaught expansion pack for the 2011 massively multiplayer online role-playing game Star Wars: The Old Republic, developed by BioWare, referenced the four hundred and thirty-ninth bomber wing.
