. It was used by the Galactic Republic some four thousand years before the Battle of Yavin. The Coruscant-class a large multi-sectioned ship, measuring 150 meters. The ship incorporated two main engine arrays, mounted on a starframe tilted at a right-angle. The engine configuration gave the Coruscant-class greater maneuverability without the need to rely on maneuvering jets. The large wing on the ship's right side was the Coruscant-class Heavy Courier's most notable feature. At a 45-degree angle to the cockpit, the heavily-armored wings had retractable fins for better control in atmospheric flights. The airlock and sensor array pylon were also visible on the wing. The ship also featured an access corridor in the neck that held a boarding ramp and escape hatch, which led to the living area. The drop bay at the base of the craft could be used as a cargo bay. Six AlderaanMotors power generators and engines were mounted in two distinctive boxes of three and were set at 90 degrees to each other on a starframe around which the rest of the courier was constructed. The ship's fuel tanks were located in the main wing, and directly fed the power generators. The Coruscant-class was armed with a forward firing pulse-wave cannon. The weapon was powerful enough to cut through the shields of any pirate vessel. Three rotating laser cannons were mounted on the Coruscant-class, one on each wingtip and one of the secondary engine array. Four proton torpedo launchers were installed on the ship, a fire-linked pair in each mandible. Each mandible had a magazine of six proton torpedoes. Each mandible also housed a single short-range concussion sphere launcher with a magazine of eight concussion spheres feeding it. Eight deflector shield generators provided protection, but the power draw was so great that they were only activated in combat.
