Several other warships are available to find and fight the enemy. Carriers are good for scouting out areas of the map and finding the enemy before becoming engaged in deadly combat. PT Boats excel in quick movement to reach remote cities, scout out areas, or chase down small enemy ships. PT Boats also hunt Submarines well, killing them in two shots. Cruisers are jack of all trades, able to fight all types of units, but are not the best of all ships for damaging specific types of enemy units.

Perhaps the most important of all the ships available are Transports and Armed Transports (AT). Both of these ships are the only unit that can capture a city, thereby earning that city's victory points for their owning player. The Armed Transports move more quickly than Transports, and can fight PT boats on equal terms. Transports are cheap to buy for capturing cities, but are instantly destroyed by any warship that can reach them.
