Fleet Increase

You send your ships to the same square (well, hex), they will merge together if you have the appropritate technology that increases your logistic.  Search your tech tree for anything that increases "logistic" and you will be able to plan accordingly and build bigger fleets.

Each ship has a Logistic value. You can combine as many ships as you want so long as their combined Logistic value does not exceed your faction's max Logistic limit for a fleet. In order to increase your limit, you need to research Logistic techs under the engineering tech tree.

Thanks.
