The Action IV transport was a medium-sized bulk freighter produced by the Corellian Engineering Corporation, belonging to the Action series of vessels.
This transport possessed a trapezoidal form and measured approximately 100 meters in length. Its cargo holds were designed with adaptable configurations, allowing for the accommodation of diverse pressure and climate conditions.
The Action IV featured a two-deck layout. The lower deck housed the bridge along with the crew's residential spaces. Two escape pods were also located on this deck. The cargo bay extended across both decks, with a smaller cargo bay situated at the front of the upper deck. A passageway extended from the front to the back of the vessel, providing crew members access to the engineering section at the rear, particularly useful when the primary cargo hold was filled or lacked pressure.
Despite being sold without any integrated weaponry or defensive shields, the Action IV was frequently upgraded with a wide range of aftermarket systems.
During the era of the Galactic Republic, the Action IV transport known as the Azure Queen was seized by Black Sun pirates while it was traveling towards the planet of Rutan.
The Imperial Navy modified several of these transports for use as Imperial Patrol Ships.
