AG - 2G quad laser cannon / Legends The Corellian Engineering Corporation AG - 2G quad laser cannon was a powerful quad laser cannon , two of which were installed on the top and bottom of the " Millennium Falcon " by Lando Calrissian and modified by Han Solo , the latter of whom also added the ventral cannons . Imperial " Lancer " - class frigates mounted twenty of these quad laser cannons , for use against fast - moving starfighters . Description . The cannons drew power directly from the " Falcon " ' s Quadex power core . Enhanced power cycler s , high - volume gas feed s , and custom - modified laser actuator s ( with larger energization crystal s ) greatly increased the cannon ' s energy output , and the weapon could destroy a TIE fighter with a single shot . Enhanced cooling packs and compressors allowed for prolonged fire without the risk of overheating . The splitter coupling dispersed the energy beam , forcing the target ' s shields to deflect energy simultaneously from two hits and increasing the likelihood of overloading the shields and inflicting greater damage . The laser barrels fired one blast at a time , following a rotation by the gunner , and had a rate of fire of 1 . 32 seconds for each barrel . The turret utilized pedals for the gunner to rotate the gun left or right , and vertical control sticks to move up or down . The turret itself could automatically rotate via the use of a ball - swivel rotation mounting and via the commands of the tactical targeting computer . The cannon ' s main control area was accessible via ladders and access tubes . In front of the gunner ' s seat were the main controls , which included twin firing grips with built - in triggers . The tactical targeting computer was slightly beyond the main controls . Several dials and buttons on the left wall constituted the system status indicators . There was also a maintenance access panel nearby . The viewports were made of transparisteel , and the directional control pedals were located near the viewport . Below the floor was the rotating platform base . For the cannon itself , it featured a horizontal support arm , four laser barrels , tracking servos on top of the turret , a laser cooling unit near the top two barrels , and the swivel mount near the bottom half , which was connected to the horizontal support arms . The cannon ' s targeting computers were also designed to augment the gunner ' s skills , were accurate up to the longest range of the weapon , and could lock on to any target greater than four meters in length that stayed within scanning range for more than 1 . 5 seconds . However , this was ineffective against most Imperial TIE models . The position of the cannons on the " Falcon " , combined with her overall design , caused their line of fire to converge into a wedge all the way around the ship . Thus , Solo and Chewbacca often held standing wagers on who was the better shot with the quad cannons , with kills scored in this area — dubbed the Money Lane — carrying a double payoff . The cannons could also be activated by remote control , and avoided hitting the pilot via a transponder . When Calrissian had the ship , the remote control was via auxiliary foot pedals in the cockpit . Solo installed trackball controllers to replace these pedals , due to their awkward design and Chewbacca ' s need for legroom .
