Steamer. Powerful, steam-propelled warship resistant to building fire that can train units, construct docks and gather fish.
—In-game description

The Steamer is a military naval vessel in Age of Empires III: Definitive Edition that is unique to the United States, replacing the standard Galleon, and can be trained at the Dock once the Fortress Age is reached. Although similar in function, it has more hit points, and has the ability to gather food and coin from fishes and whales and to build Docks.


The Steamer is a moderately fast and powerful military ship that is able to garrison soldiers. Much like the Galleons, the Steamers are classified as siege units, making them resistant to defensive structures; Outposts and Town Centers deal half damage against them. This makes them effective in both combat and transportation. They can also be used to train military units and build Docks on any coastline, making logistics more convenient.

As the nation-states of the Western Hemisphere entered a period of greater industrialization, many began to harness the force of steam power. While useful in many spheres of life, steam power revolutionized naval navigation because it lessened or outright removed the reliance of vessels on manpower, currents, or the wind. The United States made ample use of this technology, and steamboats soon traversed waterways such as the Mississippi River, the Great Lakes, and the oceans in droves.
