|Triremes are expensive ships which can be used in both attack and defense. They are not as strong as a mixed fleet of fire ships and biremes.|
|Must research Triremes in the Academy. Available at level 25.|

Speed of the unit is given for worlds with unit speed 1. (A unit with Speed 15 will have speed 30 on a unit speed 2 world).
The Trireme is a mighty enemy to encounter in a sea battle, it's defense is supreme and it has devastating weapons. However, it is expensive to build.
The Trireme's size and weapons are stronger than the bireme when it comes to defending, and his attack power is similar (but not quite) that of the Light ship. Thus making the Trireme a hybrid unit that can attack and defend. However the big cost of the Trireme (specially the population it requires) makes it a very poor choice for a naval unit in worlds with Revolt
This changes in Conquest worlds where a player must break past the enemy`s fleet and then defend his Colony ship in the harbor. In Conquest worlds it is a great unit to send when conquering a town. This is because it's high attack will help to take the city, then with it's high defense it can help defend the city from enemy's trying to retake it until you can get more support, and as it will be sent along with the Colony ship its slow speed is irrelevant.
