How much does flagship level 25 cost?

Use the amount shown on your upgrade screen. This guide does not claim an unverified current universal figure.

Why can I not upgrade my flagship?

Read the missing requirement, then inspect any prerequisite of the named cabin. Also distinguish resource shortages from level or progression gates.

No. Prioritise the rooms needed for your next goal and useful production, while tracing the complete prerequisite chain.

Check the locked slot or flagship unlock preview for the requirement on your account. Do not confuse a ship slot with a separate fleet.
