Gamma - class ATR - 6 assault transport The " Gamma " - class ATR - 6 assault transport was a heavily armed and shielded vessel produced by KonGar Ship Works for transporting stormtroopers and conducting boarding actions against starships and space stations . The Rebel Alliance and various pirate factions also made wide usage of the craft . Characteristics . Like the preceding " Delta " - class DX - 9 transport , the ATR - 6 had two general purpose warhead launchers , and a pair of forward - firing ion cannons . Both were designed to ferry troops into the combat zone to capture enemy craft . Unlike the " Delta " - class DX - 9 transport , the ATR - 6 has no frontal laser cannons . However , it more than made up for it with its four turrets , on the top , bottom , and both sides , which covered all arcs . This allowed the ATR - 6 to fire upon its target without having to fly directly at it , giving it more opportunity to inflict damage . It also crucially enabled the ATR - 6 to fend off all but the most concentrated starfighter attacks on its own . Its turrets , coupled with heavier shielding , and armor , allowed the ship to press attacks in the face of heavy fire , relying less upon supporting starfighters to soften up well defended targets . The ATR - 6 also featured stronger shields and a more heavily reinforced hull than the DX - 9 . While the DX - 9 could be destroyed with a pair of proton torpedoes , it was reported that an ATR - 6 could survive three hits from such warheads . A further development of the ATR - 6 was the " Beta " - class ETR - 3 escort transport . The ETR - 3 retains the ATR - 6 ' s base hull , giving it approximately the same size same troop - carrying capacity . However , the ETR - 3 has an additional dorsal pod , reintroduces frontal laser cannons , and has stronger shields and reinforced armor . The ATR - 6 , however , remained the mainstay of the forces already using it . History . The ATR - 6 was a deadly threat to any attacker , especially if it was an unshielded craft . During the Sepan Civil War , the Ripoblus conducted an attack on the Dimok Science Station Youst spearheaded by six Assault Transports . The station ' s defending fighters , consisting of Z - 95 Headhunters and " Delta " - class JV - 7 escort shuttles , quickly fell victim to the turrets of the ATR - 6 that they were trying to attack . When Admiral Harkov ' s forces entered the area to repel the Ripoblus , they deployed TIE / sa bombers to take out the ATR - 6s from a safe distance with proton torpedoes . Imperial pilots discovered that a full - strength ATR - 6 could survive even three torpedo hits , with several Bombers lost trying to finish off the injured ATR - 6 with laser cannon fire . Maarek Stele opted wisely to replace his payload with proton rockets , which required more careful aiming , but one of these devastating warheads was enough to quickly destroy an ATR - 6 . In groups , the ATR - 6 could take on vessels sufficiently larger than itself , especially if the proton torpedoes were replaced with the more devastating heavy rockets . One example of this was the traitor Admiral Demetrius Zaarin ' s unsuccessful recapture operation of the TIE / D Defender research facility in the Parmel system . His attacking force of Assault Transports fended off TIEs from the " Imperial " - class Star Destroyer " Adarga " and went on to inflict significant damage on the loyalist capital ship itself . Having forced " Agarda " to flee into hyperspace , Zaarin ' s transports came close to capturing the R & D facility , before being thwarted by loyalist Maarek Stele . Stele employed some innovative tactics against the overwhelming force of ATR - 6s , intercepting as many of their rockets before they could hit " Adarga " , and using ion cannons to disable any damaged ATR - 6 . In a twist of irony , loyalist Imperial forces led by Stele had earlier used the same class of ATR - 6s , though fewer , to seize the TIE Defender base . Behind the scenes . In " " and " " the ATR - 6 was described as product of KonGar Ship Works . However , " " listed Telgorn Corporation as its manufacturer . This discrepancy has yet to be explained , though it is possible that the companies collaborated on the design or that KonGar is a subsidiary of Telgorn . The follow - up ETR - 3 was produced by Telgorn . The " Gamma " - class ATR - 6 assault transport appeared in the " " series of computer games . A similar but distinct ship , " Gamma " - class assault shuttles , were first described in the West End Games publication " Imperial Sourcebook " . At first , it was unclear whether the assault " transport " was intended to be the same thing as the assault " shuttle " , because the games were known to use alternate models and statistics for a number of ships . However , both the assault shuttle and assault transport appeared in " " , proving that they were separate ships . Unlike the " Gamma " shuttle , the ATR - 6 assault transport has not been seen in many sources outside the " X - wing " games . The " Gamma " - class ATR - 6 assault transport and " Delta " - class DX - 9 transport were briefly mentioned in " The Essential Guide to Weapons and Technology " as carrying a pair of proton torpedo launchers .
