The Dugong Mark II is an upgraded version of the Dugong submarine, offering the best cost-performance ratio. It comprehensively enhances various aspects of the Dugong's performance, including the reactor, hull durability, submarine thrust, lighting brightness, and pump flow rate, while also reducing fuel consumption. Two additional floodlights are added at the bow, along with two cameras in the ballast tank, allowing direct observation of the submarine's front and ballast tank conditions, eliminating the need to upgrade the bow-mounted turret. The command room now features an extinguisher, a captain's secure locker, a weapon rack, and a remaining fuel display. An ammunition rack and two supply lockers are added in the turret control area.
