Action VI transport, sometimes referred to as the bulk transport and the modified action transport, was a popular freighter built by Corellian Engineering Corporation.
Action VI transports typically operated in convoys or in well patrolled areas of space. Since they lacked even the most basic forms of self-defensive measures, such as armor and weaponry, they were often prime targets for pirates and so had to rely on protection from other capital ships and starfighter escorts. The only reason they were used by the Galactic Empire was because they were quite inexpensive relative to Imperial wealth. One of these ships once crashed on Blenjeel, after crossing paths with an Immobilizer 418 cruiser.
The Rebel Alliance also employed these cargo vessels, often as personnel carriers, but in much smaller quantities since they were far more expensive than GR-75 medium transports. Most Action VIs were stolen from the Empire.
Pirates often modified Action VI ships into "interceptor frigates" capable of combating corvettes. The most famous Action VI was Wild Karrde, the personal starship owned by smuggler Talon Karrde.
