The Action IV Transport is a reliable bulk freighter that is disparagingly called by pirates as the "Inaction" freighter, due to its incredible vulnerability brought on by its lack of ability to stand up to any attack. Typically, these ships are found either in convoys or well-patrolled areas. Only due to their extraordinarily inexpensive costs per ton to purchase, maintain and operate do these ships continue their existence. It appears that CEC put out two models of the Action IV. Model 1 which is still available new, but lacks many features. And Model 2 which is no longer available new; featured stronger hull, shields, a different sensors package, and the ability to enter the atmosphere. The reason for the discontinuation of the Action IV Model 2 is unknown.

    Interestingly, the Empire has also found uses for this vessel. In secret weapons research programs such as the Ando Project, the Empire employed a modified Action IV called the Eclipse to move the project's necessary materials, since the nondescript vessel would raise little attention during its travels. In other cases, such as in the area in and around the Itani Nebula, modified Action IV "patrol ships" can be encountered. These vessels provide supplies to outlying systems and bases, and conduct the occasional starport and customs inspection. The Darknon Station, a non-Imperial station is one such stop for these ships. Patrol Ship captains primarily rely on the fear of the Imperial Navy to protect their ships. Pirates such as the Des'maric Pirates operate a heavily modified Action IV called the Asagov Raider. Although the vessel is capable of taking down any light freighter, it does not partake in raiding to ensure its safety; for its primary purpose is to serve as a mobile main base.

    It is known that some smugglers who operate the Model 2 fill most of their holds with "legitimate cargo" (that never leaves the ship), while the remaining 1,500 tons is dedicated to their true, and most illicit cargoes. Meanwhile, other smugglers haul their illicit cargoes along with their legitimate goods for delivery. Rumours are abound that several pirate groups and the Rebellion have employed the Action IV as a starfighter carrier, by converting its main cargo hold into a hanger. However, according to a famed smuggler, Platt Okeefe no more than two or three X-Wings could be carried, after factoring in needs such as power requirements and maintenance space.

    Modifying the massive void that is the main cargo hold is possible, although a situation fraught with problems. Some ships have opted to create multiple holds that are either partially or fully pressurized, and/or are climate controlled. Meanwhile, other ships have compartmentalized the forward cargo bay with staterooms for passenger transport. Conversion of the main cargo hold into passenger space is considered to be too risky, unless the whole hold is compartmentalized with pressure seals, as hull breaches commonly occur during combat.

    In its unmodified form the Action IV proves to the be dream prize for pirates. In the case of fitting weapons to the design, most modified ships place their turrets below the bridge and on the dorsal portion of the engineering section. Customized weapon systems such as concussion missile launchers are rarely fitted. Should turbolasers be fitted and kept constantly charged, this can occasional drain power away from other systems such as hyperdrives, sublight drives, and shields.

    This bulk transport is comprised of three main sections; forward, cargo and engineering, with all those sections being split into two decks. Nestled to the left of the bridge which has stations for the captain, first officer or navigator, sensors, communications, and shields is the life support systems. To the right of the bridge is the computers. Situated behind the bridge are a pair of shield generators and four functional crew cabins. It must be noted that most of the ship's electronics are located on the command deck. From the crew lounge the ship's escape pods can be accessed. Boarding ramps and hatches can be found on the port and starboard sides, and lead to the crew lounge and galley. On the deck above the bridge (bridge is lower deck) can be found the forward cargo bay. Cargo is loaded into the forward bay via blast doors which connect it to the upper deck of the main cargo bay. Personnel access to this bay is possible via a ladder from the crew lounge on some freighters.

    Located near the forward cargo blast doors is another ladder that allows entrance to the topside access conduit. This conduit runs the length of the ship, connecting the forward and aft systems (accommodating the power generators) via wires and piping. In the event that the main cargo hold is chalk full or depressurized, crewmen can use the conduit to travel to the engineering section. The cargo section (main cargo bay) is one large void (assuming if stock configuration is kept) with a large cargo lifter in each corner, in the forward part of the cargo hold. Blast doors to the command deck (and forward cargo bay) as well as the engineering section can be found. Massive hatches on the port and starboard sides, located closer to the forward section maintain their own retractable ramps to allow goods to be loaded or offloaded.

    The engineering section is occupied by the ship's machinery on both the upper and lower decks. Large systems such as power generators, ion drives and hyperdrives can be found here, as well as spare parts storage and ship's fuel. For those reclusive technicians, the corners of the engineering section can be made into makeshift quarters.
