The Imperial convoy ship functioned as a Galactic Empire vessel, specifically a variant of the Imperial cargo ship.
Resembling a Star Destroyer in form, the ship featured a raised section leading to the bridge and possessed a minimum of two engine units. Its cargo bay had the capacity to accommodate at least one TIE/LN starfighter alongside other freight. Due to its straightforward operation, a single crew member could pilot the ship.
In 3 ABY, one particular vessel transported a crucial component of the Death Star II's weaponry. It was intercepted by Wolf Squadron, resulting in the death of the crew. The Rebel's then took the ship to their base located on Annamar. Subsequently, Darth Vader spearheaded a mission that successfully retrieved both the ship and its important cargo.
