Ship types

  • Motor torpedo boats occupy the lower tiers of naval vessels and are equipped with multiple torpedoes and, occasionally, guns.
  • Corvettes and destroyers, being larger in size, boast a more extensive array of armaments, including slightly more powerful guns.
  • Cruisers serve as a middle ground between destroyers and battleships.
  • Battleships and dreadnoughts are equipped with immensely powerful main cannons and may carry minimal aircraft supply for anti-submarine defense.
  • Submarines can navigate underwater, rendering them impervious to certain attacks; however, they must resurface to utilize certain weapon systems.
  • Hovercraft are versatile vessels that can travel on both land and water.
  • Rams are purpose-built vessels designed for ramming other ships.
  • Dredgers can manipulate land, creating new terrain by clicking ahead of their path and obliterating old land by sailing over it.
  • Icebreakers can plow through ice and snow without taking damage.
  • Aircraft carriers command a squadron of aircraft which follow your mouse cursor to attack enemy ships!


  • Torpedoes - powerful underwater weapons. Some can track enemy vessels with sonar.

  • Rocket torpedoes - deploy a torpedo when in the vicinity of an enemy submarine.
  • SAMs (surface-to-air missiles) - can shoot down aircraft and missiles.
