The BT-45D U-wing, a transport variant produced by Incom Corporation, served as the non-military counterpart to the UT-60D U-wing starfighter/support craft used by the military. Lacking both military armaments and a hyperdrive, the BT-45D became popular among private security organizations across several worlds situated in the Mid Rim throughout the reign of the Galactic Empire. In contrast, the UT-60D experienced only a brief production period leading up to 0 BBY. Incom Corporation repurposed previously designed features for the BT-45 model.
The U-wing section of Star Wars: Rogue One: The Ultimate Visual Guide, a 2016 reference book authored by Pablo Hidalgo, marked the initial mention of the BT-45D U-wing.
