The sleek fuselage of the X-wing starfighter is 12.5 meters long. The long, narrow spaceframe is flanked in the aft quarter by four massive realspace engines. Each engine has an aerodynamic S-foil mounted on it. The wings not only serve as stabilizer surfaces in air travel, but also distribute deflector shield energy and serve as weapons mounts. The surface of each S-foil bears squadron and fighter markings.
Located midway through the ship is the X-wing's cockpit module. Behind the X-wing's cockpit is an astromech socket. The astromech droid provides astrogation data for the fighter's hyperdrives, and serves as a co-pilot and technician during flight. Three landing gears extend when the fighter is docked.
