MFB - 4 Mobile Repulsor Base The MFB - 4 Mobile Repulsor Platform was a type of repulsorlift platform that was used by the Galactic Empire . These bases were used for preliminary scouting and survey missions and played supporting roles in planetary occupations . History . During the Galactic Civil War , the Empire deployed an MFB - 4 platform on the aquatic planet Alluuvia , using it as their base of operations on the planet . However , the platform was attacked by a team of Rebel Alliance agents , working in conjunction with a group of Ithorian pilgrims and some Anguilla warriors . The Imperials were subsequently driven from Alluuvia . Characteristics . The exterior of the base contained most of the MFB - 4 ' s extensive and deadly defenses , especially against an aerial assault . Four laser cannons , one at each corner , had a range of six kilometers and were manned by dedicated gunners . The centrally located heavy turbolaser could hit targets thirty kilometers distant and was manned by four dedicated gunners . A pair of twenty meter - tall sensor towers at opposite ends of the base detected incoming enemy forces , while various short - range sensor arrays studding the base ' s exterior could detect operatives attempting to sneak in . The base ' s shield generators were located on the topside of the base and generated an energy field which could deflect most enemy fire . Finally there was a landing pad atop the base , which connected to the interior through a secured access hatch . Emergency access panels and doors allowed for access to the weaponry , sensors and shield generators , however these were secured through the use of rank cylinder s . Though possible to bypass this security failure in this regard or , through sheer strength , tearing the access panels off would would trigger an alarm in the base ' s computer room . Interior Layout . Each MFB - 4 base was divided into three levels , accessed by the central turbolift running up to the exterior landing pad . Vitally important rooms , including the computer control room , fighter hanger , armory , detention block , and vehicle storage bays were secured by blast doors which only opened to an appropriate rank cylinder . Though it was possible for an enemy operative to bypass these safeguards , failure would sound an alarm in the computer control room . Level 1 . The top level was the personnel deck , dedicated to housing the base ' s support personnel along with other vital functions . The computer control room was the nerve center of the base and controlled everything from life support to the repulsorlift engines and shield generator . It was staffed at all times by four technicians and a pair of troopers . Next was the communications room , staffed by four technicians and one trooper , which controlled all of the base ' s sensor and communications equipment ( including subspace communications to nearby star systems ) . There was also a TIE / LN starfighter hanger with space for twelve fighters and support from a half - dozen technicians ; fighter launches and retrievals were facilitated by the topside launch chute . Four personnel quarters provided living room for the base ' s 120 support personnel , while two pairs of offices and meeting rooms were given over for use by high - ranking individuals at the base . Computers in these offices were connected to the ones in the computer control room , though they required the correct password to use . There were also a couple of storage rooms dedicated to common goods like food , clothing and repair parts . Finally there was a galley able to feed 300 people at once and a lounge for off - duty personnel to relax , whether by watching holovids or playing a game of sabacc . Level 2 . The barracks deck was used to house the Imperial Army presence in the base . Eight separate rooms provided living space for up to 300 troopers while separate mess and training halls saw to their daily needs . There was also a medical bay staffed by four MD - 5 medical droid s and containing two bacta tanks , two complete surgery suites and four recovery rooms . A droid bay provided storage racks for dozens of droids of different sizes along with power rechargers and a complete repair and maintenance shop . The armory stored the base ' s dozens of blaster rifles , pistols , grenades and heavy weapons , along with blaster power packs and a recharging station . A single trooper guarded access to the armory . Finally a detention block was used to hold any captured prisoners , with at least four troopers overseeing the prisoners at all times . Level 3 . The vehicle bay deck contained a pair of vehicle storage bays which could be used to hold a variety of vehicles ; for example on an aquatic planet a bay can be fitted with racks to hold fifteen TIE Fighter Boat s or a combination of 100 Single person waveskimmer s and fifteen Aquatic Scout Ship s . These were launched by the base ' s underside launch chute , which could be angled to accommodate different vehicle types . There were also another pair of storage rooms on this deck for containing common goods and a mustering hall used to stage troops and vehicles for deployment . Finally there were a pair of research labs used for a variety of scientific endeavors . Access to these labs was controlled by simple entry code and their computers were linked to those in the computer control lab , though a password was necessary to access them .
