During each turn Consolidated PBY Catalinas scout out the location of the enemy task force comprising Akagi, Kaga, Soryu, and Hiryu.

Once a Task Force has been identified and are within range a strike group may be launched from neighboring ships.

Fighters (F4F Wildcats or A6M Zero 'Zekes') can also be established in a combat air patrol (CAP) to protect their carrier.

The game ends when either sides carriers are all lost, or if one of the task forces leave the map.
