Class four container transport

Class four container transports, also called a class four freighter, Imperial Class 4 Cargo Ship or more simply as an Imperial cargo ship, were tetrahedral, hyperspace-capable, bulk freighters built by Kuat Drive Yards and used by the Galactic Empire to haul large numbers of crates and containers across the galaxy.
==Characteristics and role==
The class four container transport was shaped like a tetrahedron resting on the longest of its six edges. The bridge module was located in front of the ship, at the narrowest vertex of the recumbent tetrahedron, and resembled that of the Arquitens-class command cruiser. Atypical standard yield for a class four transport was 230 large containers, which were attached to the rear triangular side of the ship, encased between the sublight engines positioned at each of the three angles. However, containers could be removed to make room for a hangar bay at the rear of the cargo portion. The cargo of the transport could be accessed from the inside through at least one entry and exit point between the cargo and the vessel.
In addition to its sublight drives, the Imperial class 4 cargo ship was equipped with a hyperdrive, which allowed it to travel through hyperspace. It was also armed, boasting one top-mounted double-barreled turbolaser battery and two side-mounted laser turrets. As a Class four freighter, Imperial cargo ships were required to have sublight re-entry thrusters equipped in all of their cargo containers in case of an emergency jettison; these engines were meant for last-ditch efforts and could only be fired when inside a planetary atmosphere. Additional safety measures included six escape pods stored in a section on the sides of the ship's bow which could be remotely jettisoned in case of an enemy boarding action to trap the intruders on board the ship.
Every Imperial cargo ship required the presence of an inventory droid. Such droids were responsible for arranging the cargo and monitoring all the goods to ensure it was organized and safely arrived at its destination on time. Also, inventory droids were tasked with logging every item and crew member of the transport and in addition were able to view the Imperial data network. Imperial cargo ships were used to haul large quantities of containers and crates from spaceport to spaceport. For security purposes, Imperial cargo ships had stormtroopers and a security complement of at least five DT-series sentry droids.
==History==
===Early Empire===
Class four container transports were in use shortly after the formation of the Galactic Empire. On a mission to Corellia, the rogue clones of the Bad Batch got past the planet's sensors undetected by attaching their shuttle, the Marauder, to the underside of the freight assembly of a transport approaching the planet, detaching when the ship was close enough to the planetary surface.
Some time later, near 18 BBY, the Bad Batch again encountered Imperial cargo ships, this time in Count Dooku's former palace on Serenno when they were tasked by Cid to steal part of the Count's war chest before it was taken over by the Empire. Three Class four transports, including Transport Three, were involved in a massive transport operation based on the palace and guarded by Clone Captain Wilco and a force of clone stormtroopers. Wrecker, Tech, Echo, and Omega successfully infiltrated Transport Three while Hunter was providing cover, but the first team was trapped inside the ship when Captain Wilco ordered it to take off and detach its pods after noticing Hunter. Echo decided to jettison a cargo container in a desperate effort to use it as an escape vessel thanks to its emergency re-entry thrusters, but due to the container's thrusters malfunctioning the team was left trapped while it was freefalling to the planet, although the thrusters eventually fired and allowed them to survive the fall.
Later in 18 BBY, multiple class four transports traveled from the planet Erebus. At one point, when the Empire liberated the planet of Chorin, several class four container transports arrived with the Imperial fleet.Target Vader 2
===War with the Rebellion===
In 3 BBY,Dawn of Rebellion dates the attack on Phoenix Squadron to three years before the Battle of Yavin, or 3 BBY according to Star Wars: Galactic Atlas dating system. As the heist at Horizon Base take place immediately before the attack on Phoenix Squadron, it can be determined that it also takes place in 3 BBY. the rebel astromech Chopper stowed away on an Imperial cargo ship docked at the Horizon Base. Eventually, the astromech joined forces with the ship's inventory droid, an RA-7 protocol droid called AP-5, to steal the vessel from the Empire. In order to do so, Chopper managed to trap the stormtroopers serving aboard the ship in the freight assembly, before jettisoning the soldiers along with the containers. AP-5 then transmitted the coordinates for the planet Atollon to Chopper's Spectres and the Phoenix Cell despite the opposition of the Imperial captain. Chopper then rendezvoused the cargo transport with the rebels above Atollon.
In 2 BBY, the Weequay pirate Hondo Ohnaka and the Jablogian crime lord Azmorigan acquired the flight plan for a cargo transport. They disabled the transport with ion mines. However, the ship drifted into the upper atmosphere of the planet Wynkahthu, where it was trapped in a storm. Most of Hondo's Ugnaught crew with the exception of Melch were lost while boarding the ship. Hondo and Azmorigan managed to reach the ship with the help of the Spectres and AP-5, who was familiar with that class of ships. They managed to restart the ship and steal a cargo of proton bombs and treasures. However, the recovery team was forced to flee when it accidentally activated the sentry droids. The recovery team fled back to their starship, the Ghost, before the cargo ship descended into the vortex and exploded.
Later, during the Spectres' attempts to liberate the planet Lothal from the Empire, Hera Syndulla, at Ohnaka's suggestion, latched the Ghost onto the hull of a container transport to sneak past the Imperial blockade of Lothal. After waiting for some time, they latched onto the ship once it exited hyperspace, successfully passing through the Imperial blockade.
==Behind the scenes==
The Imperial cargo ship appears in the Star Wars Rebels series, first appearing in the second-season episode "The Forgotten Droid." Dave Filoni, supervising director of the show's first two seasons, built a model of the cargo ship out of a manila folder when the show's crew was breaking the story of "The Forgotten Droid."
