You can see the cost of your fleet by resting your cursor over the credit total. A breakdown of your income and costs will appear. Fleet costs take a large percentage of credits, smaller percentage of metal/crystal.
So I am like 4 years late on this game. I have been playing the game for 2 weeks now. I still cannot find the ship supply increase for TEC. I keep on getting bet over when the CPU attacks with multiple capital ships. I have gone the tutorials 4 times. I have gone through the forums here. But I cannot find the TEC increase on their research tree. any help?
When you open up your research screen you should see selections down the left side of the window.

Click on Fleet Logistics.
It will take you to this screen:

The research in the bottom box increases your fleet supply at the cost of permanently taking away a percentage of your resources. The research in the top box increases the number of capital ships you're allowed to field. This screen is similar for all three races.
Thanks a lot. I thought it was on the research tree.
