Imperial Supply, which is also referred to as the Imperial Supply Fleet, functioned as the logistical arm of the Galactic Empire's Imperial Military. It was probably a division of the Imperial Navy, considering that graduates from the Imperial Merchant Galactic Academy had to fulfill a commitment to the Imperial Supply Fleet before they were able to fully integrate into the Merchant Galactic, a civilian support force for the navy.
During the year 9 ABY, following directives from Grand Admiral Thrawn, they established a residence for the clone of the Jedi Master Jorus C'baoth located on the planet Jomark.
