|Triremes are expensive ships which can be used in both attack and defense. They are not as strong as a fleet of light ships or biremes.|

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; however, it is expensive to build.
The Trireme's size and weapons are weaker than the Bireme when it comes to defending, and the attack power is similar (but not quite) to 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 the high attack value will help to take the city, then with the high defence it can help defend the city from enemies trying to retake it until you can get more support. Since it will be sent along with the Colony ship the slow speed is irrelevant.
