Barracks

Houses your fleet's crews and sets how large an army you can field. Your total army capacity is the sum of all your Barracks.

Determines your maximum fleet capacity. Each warship takes up a number of capacity slots based on its size, and your combined Barracks levels set the total you can hold. Running multiple Barracks is how you field a large fleet.

Each Barracks level raises your army cap. If you can never seem to build more ships, your Barracks capacity — not your resources — is usually the limit.
