When enemy forces are able to deny access to the skies, and geography prevents land-based warfare, the Imperial Terrestrial Navy serves as The Empire of Drakonia's fighting forces. The Navy uses hovercraft, submarines, and small ships to seize control of liquid (water or otherwise) areas. Hovercraft are used to transfer ground troops from ship to shore or across small bodies of water, traveling at high speeds several feet above the waves. Massive submarines carry invasion forces close to hostile shores, and provide covering fire with naval-sized artillery. These submarines are large enough to carry anti-orbital weapons and carry considerable amounts ofaircraft. Smaller ships use fission-tipped hypersonic missiles and swarm torpedoes to hunt down enemy vessels.
