Anthonyzappulla,
If you have a Naval Base, and spare Supply Ships, and you have a Navy Supply Fleet Deployed (not just inside the setup screen, but actually deployed successfully to the base). And the issue you are suffering is that your Supply Fleet isn't resupplying your carrier group. Then the most likely causes are as follows...
1). You do not have all the necessary supplies the Carrier Group needs. If you lack some of the necessary ships, ammunition, supplies, planes, etc. Then the Supply Fleet will wait until you get them, before it resupplies your fleet.
2). You are at peace. In order to prevent the war system from placing extreme load on the servers, part of the supply system is turned off during peacetime. The supply units become "active" again, when you declare war. Until then, getting them to work can be difficult to say the least.
Personally I find the peacetime supply system to be
Ah fleets, with cruise missiles that were OP as hell... miss those days. lol

Ahhh I see what your saying
So what I did was dismantle carrier and supply fleet. Made new ones and bought everything before I put together new unit. So far so good.. Thanks much!!
