The Atakebune fires a burst of three rockets (despite the UI saying 6), with each shot having a 0.375-tile radius Area of Effect, with damage scaling down to 40% and 20% of its maximum towards the edge. It can only fire from one side at a time, with each side sharing the same attack cooldown, and can fire while moving.
The Atakebune is essentially a standard Warship with slightly less attack and fewer hit points that costs 60 fewer resources. They lose one-on-one with a Warship, but are slightly more cost-effective vs springald ships and archer ships.
Originally, the Atakebune cost 170 food and did 30 damage per rocket. With update 11.0.782, it costs 100 food and does 40 damage per rocket.
Trivia[]
Historically, the atakebune did not have spars and sails, and its height was higher, which its Age of Empires III counterpart did all of them correctly.
