MG - 100 StarFortress SF - 17 The MG - 100 StarFortress SF - 17 , also known as the B / SF - 17 heavy bomber , was a model of heavy bomber manufactured by Slayn & Korpil for use by the New Republic during the late stages of the Galactic Civil War . Following the Galactic Concordance and New Republic disarmament , the ship was primarily used in civilian applications . Several ships were used by the Resistance during its war with the First Order around 34 ABY , earning it the name Resistance Bomber . Characteristics . The MG - 100 StarFortress SF - 17 was a heavy bomber manufactured by Slayn & Korpil . The starship featured three sublight ion thrusters , a single hyperdrive , and artificial gravity projectors . At the bottom - front of the ship strutted a targeting sensor mast , which contained a targeting sensor and active - tracking array . Two short range comms antenna were located along the top of the ship along its keel line . Jutting horizontally from the ship ' s profile were two stabilizer foils . In total , the ship was crewed by five individuals . A single pilot and flight engineer operated within the armored cockpit . The bombardier operated a targeting pedestal on the flight deck , and two gunners operated the rear and ventral ball turrets . The B / SF - 17 ' s intended purpose was to deliver a payload of 1 , 048 proton bomb s on top of a target . The modular bombing magazine , called the " clip " by the bomber ' s crew , would drop the bombs through sequenced electromagnetic plates in the clip , which propelled the bombs to " drop " in microgravity environments . The bombs would then be drawn magnetically to their targets . The assembly could be programmed to drop specific sections of the payload in sequence , but the most common configuration was " deploy all . " To drop the ship ' s payload , the bombardier on the flight deck monitored a concentrated sensor feed . The system calculated the optimum time for release , and at a given prompt , or at the discretion of the bombardier , the control button on a wireless remote triggered the release of the payload . A magnetic seal retained the atmosphere when the bomb bay doors were open . Ball turrets on the StarFortress were encased in an armored transparisteel shell , while deflector shields protected the gunner . Despite this protection , many gunners felt exposed to enemy fire . Other turrets included a remotely operated dorsal turret of similar firepower to the EM - 1919 paired repeating laser cannon s installed on the ball turrets , two remote - linked cannon arrays at the rear of the vessel , two forward laser canons , and two more laser canons , one on the tip of each stabilizer foil . As a bomber , the MG - 100 Starfortress was slow and ungainly , making it prone for starfighter attack . Resistance flight instructors taught bomber crews to fly in tight formation , opposing attacking fighters with overlapping fields of fire . The rear and ventral turrets offered a potent defense against attackers approaching from below or from the rear , but were less effective against threats from above or in front of the bomber squadron . Escort duty for starfighter pilots were difficult assignments for pilots owing to the sacrifice of their vessels speed advantage in order to stay close to their assigned bombers . Enemy fighters would try to lure such escorts away , leaving the bombers exposed . History . Dating back to the final days of the Galactic Civil War , the New Republic contracted with Slayn & Korpil for the MG - 100 StarFortress , a dedicated heavy bomber that could deliver a larger payload than starfighters . Part of the ship ' s intent was to help capture besieged Imperial holdouts . The ship saw reduced manufacture during the decades of peace that followed . The Senate ' s subsequent demilitarization effort sent many StarFortresses to the scrapyard . Other decommissioned craft saw widespread civilian use . Mining companies used them to drop explosives that broke up ice and rock , local governments deployed them as rescue ships , fuel tankers , and fire - fighting craft , and scout services relied on them for celestial mapping and exploration . The modular bomb magazine could be easily repurposed for remote cargo drops . With the creation of the Resistance in 28 ABY , several StarFortesses found their way into the new paramilitary organization , and were absorbed into its Cobalt and Crimson Squadron s during the cold war and First Order – Resistance war . Multiple craft were used by the Resistance during the evacuation of D ' Qar to drop proton bombs onto the " Mandator IV " - class Siege Dreadnought " Fulminatrix " . All of the Resistance ' s bombers were destroyed during the battle , with only one reaching the target area . This lone bomber , manned by Paige Tico , managed to complete its bombing run right before being destroyed , taking out the " Fulminatrix " mere seconds before it could destroy the Resistance flagship , " Raddus " . Behind the scenes . The MG - 100 StarFortress was first seen in the first teaser trailer for on April 14 , 2017 . Though they were initially thought to be " Starhawk " - class battleships , on April 18 , 2017 , Lucasfilm Story Group member Leland Chee confirmed on that they were not Starhawks . According to " " , the original concept name wasn ' t MG - 100 StarFortress SF - 17 or B / SF - 17 heavy bomber , it was actually " T - wing " . You can still see the T - like shape of the ship by looking at final bomber design from the front and top .
