The Mark I Bulk Transport was manufactured by Sienar Ships. It had two decks and while it lacked deflector shields, the ship did have a dorsal laser cannon turret. A common starship in the more civilized regions of the galaxy, it was nevertheless considered to be an easy target for pirates. As of the Galactic Civil War, production of the Mark I had ceased but they were still sold second-hand at a high resale price. The Cygnante was a heavily modified Mark I used by the Shield.
