They are the very first Siege Naval unit to appear in Age of Empires series and are the predecessor of the Cannon Galleon of Age of Empires II and the Monitor of Age of Empires III .
Strategy 
Edit
It has fewer hit points and fires slower than its original counterpart, but more than makes up for it with damage per projectile, more range and doing damage to a certain location rather than a single unit. Because of its relative low amount of hit points compared to other units, a successful naval victory through a full-scale assault can be obtained by escorting them with a large group of Triremes.
Being a Trireme, it is not an upgrade to Trireme itself, but a separate unit. It can be upgraded into a Juggernaught once Engineering is researched. It benefits from such researches as Alchemy for its attack strength, Ballistics for its accuracy and Engineering for its range.

History Edit
"The ultimate warships of antiquity were advances on the trireme that occurred after the death of Alexander the Great. These ships were first broadened so that multiple rowers could apply power to each oar. Based on limited descriptions and detailed figures from crew and rowers, it is believed that the largest ships of this period may have had catamaran hulls. The broadening of ships and decks added weight and further reduced speed and maneuverability, but increased stability. Decks supported catapult artillery and large marine contigents. Ships engaged each other primarily with missile fire and boarding."—Age of Empires manual
