Age of Empires Series Wiki

Ottoman super-heavy artillery. Moves and fires slowly, but does tremendous damage against infantry or buildings.
—In-game description

The Great Bombard is an artillery unit in Age of Empires III that is unique to the Ottomans, which replaces the Heavy Cannon, and can only be trained at the Factory or shipped from the Home City.


The Great Bombard is a slow and heavy unique artillery piece used by the Ottoman Empire, which can only be created by Ottoman factories or sent from the Home City. The Great Bombard has a giant damage output, shredding any infantry it encounters on the way with just two of them. The Great Bombard is also excellent at taking out enemy buildings with this extremely high damage. They also have a relatively high amount of hit points.

However, the Great Bombard does have its own disadvantages. Being the largest (and heaviest) artillery in-game, they are extremely slow when moving and will need protection against surprise rushes against the Bombard. They also have a relatively slow firing rate compared to the Heavy Cannon and Rocket from other civilizations.

Hidden cost[]

Training the Great Bombard at a Factory takes 115 seconds (109.25 with Chinese TEAM Engineering School card, 103.5 with Engineering School card and 97.75 with both). The average resource gather rate of a Factory is 5.5 every second (before the Factory improvements (+20%)). This means that the Great Bombard, while appearing to be free, will have a cost dependent upon how effective the Factory gathers a needed resource. In many cases, this cost can exceed the base value of the unit.

Great bombards were a set of medieval cannons that were cast of bronze or iron and fired stone projectiles weighing hundreds of pounds. The greatest of these was a cannon called 'Basilica' that pounded the walls of Constantinople. It was over 25 feet long, used hundreds of pounds of powder that, with a projectile weighing in excess of 1,200 pounds, took hours to load. The bombard was so huge that it had to be constructed in two pieces that screwed together to make it, presumably, easier to move. This meant it only took 60 oxen and hundreds of men over 40 days to move the bombard the 120 miles between Adrianople and Constantinople at an achingly slow two miles a day!
