T / D Technology T / D Technology was a campaign undertaken by the Galactic Empire during the Galactic Civil War to recover advanced TIE / D Defender technology from rogue Grand Admiral Demetrius Zaarin , in the Zaarin insurrection . It took place in the Parmel system . In it , ace TIE pilot Maarek Stele succeeded in recovering the technology after several battles , including three Defenders , two of which were prototypes at Research . The Campaign . Capture Platform . With the loss of the Empire ' s ability to manufacture TIE Avengers thanks to Zaarin destroying the Seinar Fleet Systems factories located in the Omar system . Zaarin focused his efforts onto his Research platform to steal the prototypes and technology of the TIE Defenders . Fearing that the Rebel Alliance could gain a reprieve , which in turn Zaarin could take advantage of , Loyalist forces sent 3 TIE Defenders to stop Zaarin ' s raiders from stealing the technology . When they arrived four Cargo ferries " Sakin " were in the process of docking with containers that likely contained TIE Defender prototypes . One managed to escape , while the Defenders were engaging TIE Bombers while also disabling multiple Lambda - class T - 4a shuttles carrying officers and technicians that were needed to be interrogated . By the time the Bombers were destroyed , one of the ferries escaped , but the other three were destroyed before they could make of with the containers . Soon reinforcements arrived with a " Ton - Falk - class escort carrier " " Jitte " arrived with a contingency of TIE Fighters that were heavily modified to carry shields and warhead launchers . However the fighters and the " Jitte " were all destroyed and the platform was disabled and captured by assault transports . When the facility was captured , Imperial - class Star Destroyer " Adarga " arrived to reinforce the station . Soon a small Rebel starfighter force arrived but was eliminated by the TIE Defenders . Hold Platform . The Imperials knew that Zaarin wasn ' t going to give them a reprieve as Assault Transports escorted by TIE Defenders attacked the " Adarga " . The " Adarga " was badly damaged and had to withdraw . With the Star Destroyer neutralised the strike force turned its attention to the Research platform . The only TIE Defender the Empire had managed to muster managed to destroy the transports and disable the rogue TIE Defenders , while Escort shuttles Red Knight arrived as reinforcements . Tugs were dispatched to pick up the Defenders . Not long afterwards two Corellian corvettes Uhu arrived and attempted to deploy probes Keyhole to monitor the area . They were both destroyed before they could finish deploying the probes . Protect Evacuation . With the Adarga no longer in use Imperial command decided to evacuate the base . They transferred the two remaining prototypes , Proto 11 and Proto 12 onto a BFF - 1 bulk freighter " Mharsup " and the remaining personnel , one of which was the chief Scientist of the project , onto a Lambda - class T - 4a shuttle G ' nabgib . When the freighter arrived with two escort shuttles " Dragonfly " , rogue Assault Gunboats arrived to engage the remaining defenses . Soon into the dogfighting Grand Admiral Zaarin arrived in his flagship the Star Destroyer " Glory " . The " Glory " launched stormtrooper transports , TIE Defenders , TIE Avengers , modified TIE Bombers and tugs . Despite his forces outnumbering the Loyalist forces , the station was successfully evacuated and both the freighter and the shuttle jumped to Hyperspace , leaving only the facility to destroy . Escort to Rendezvous . The " Mharsup " then arrived to rendezvous near bouy B - 0F9 to transfer the prototypes to Modified corvette " Hashim " to transfer the prototypes , then the corvettes would travel to Admiral Thrawn where they would be safe . But the rendezvous area was the site of a recent Rebel attack , and despite the Alliance , not usually known for attacking the same place twice , decided to send fighters to the transfer area . Firstly by sending A - wings , one at a time . Soon B - wings arrived , followed by 3 X - wings along with 3 Stormtrooper transports , " Storm " , which contained Commandos , indicating a capture operation . The attempt to capture the freighter was a failure thanks to the Single TIE Defender and destroyed the Rebel forces . Soon " Hashim " arrived with Assault Gunboat Nu Squadron as escort . Just as they arrived 6 Y - wings arrived to make torpedo runs on the corvettes . Gunboats " Nu " , with the help of the TIE Defender destroyed the Y - wings . However a Nebulon - B frigate " Hunu " arrived and started launching Z - 95 Headhunters . Both Imperial squadrons managed to resist long enough for both the freighter and the corvettes to transfer all the TIE Defender prototypes and entered hyperspace . By the time the frigate was on its last leg , Zaarin sent his own forces of TIE Avengers but were also defeated . Trapped by Pirates . However , the corvettes soon came out of hyperspace near bouy CRM - 114 , to find themselves in a Ion mine field laid by Rneekii pirates , and were unable to escape on their own , as they were they were outnumbered by multiple R - 41 Starchaser s and a Strike - class medium cruiser " Intombe " . They called for reinforcements but feared that they may not arrive in time , so they sent the TIE Defender that was still combat worthy to fight the pirates . By the time the Defender was launched shuttle " G ' nabgib " was already boarded by Ibutho 1 and the chief scientist and the data was stolen and the transport jumped to hyperspace . The Defender destroyed all the other transports from Ibutho flight group and fought of the R - 41 Starchasers while the corvettes soon became disable with no means of moving to their meeting with Thrawn . Assault Gunboats soon arrived and the Pirate threat was neutralised . Sparing the threat of the prototypes being captured , for the moment . Transfer Prototypes . 3 Cargo Ferries Mssan were brought in to repair the corvettes and transfer the TIE Defenders to each one , with the space combat worthy one to dock with Mssan 3 . However two of them arrived 24 Klicks away and a Rebel starfighter strike force , consisting of 2 A - wings , Azul Squadron , 2 B - wings , Blue Squadron and 4 X - wings , Red Squadron had just arrived , at a relatively long distance of about 20 Klicks but were still a danger to the ships . The TIE Defender once again had to be deployed to fight the Rebels . However , while the lone Defender helped Gunboat escorts deal with the Rebel raid force , another pirate group of Y - wings , T - wings and a YT - 1300 transport " Dhoora " , belonging to the Nami , arrived very close to the corvettes and disabled them so that the " Dhoora " could board and capture one of the corvettes . By the time the Imperials arrived , they were too late as the party escaped to Hyperspace with the TIE Defender prototype , Proto 11 . To make matters worse Zaarin sent his own TIE Defenders to battle , although effective against the Gunboats , they were also defeated by the lone TIE Defender . Soon the Cargo ferries reached the stranded ships and were about to pick up the other prototype and repair the two corvettes when a light Mon Calamari Cruiser " Sumpntodo " belonging to the Rneekii arrived to launch Z - 95 Headhunters , they were driven of again by the Imperial fighters and the combat worthy TIE Defender docked with " Mssan 3 " and both ships managed to reach Thrawn . Aftermath . Although the TIE Defender technology and prototypes reached Thrawn safely , the loss of the main research facility and the potential manufacturing facilities meant that the TIE Defender would see little action afterwards in the Empire ' s service . Combine this with the danger of two renegade pirate factions , the Rneekii possessing the data and chief scientist of the project , and the Nami possessing a prototype meant that it was possible for TIE Defenders to be manufactured outside the Empire ' s control . Knowing the serious consequences of such sophisticated technology in enemy hands , a " Crash program " was needed to counter this problem as soon as possible . Thrawn would soon collaborate with Cygnus Spaceworks to develop a new starfighter . Behind the scenes . The T / D Technology is Battle nine in Star Wars : TIE Fighter .
