Currently, federation fleets take a fixed % of a federation's naval capacity and turn it into a combined federation force, up to a flat cap. But this cap is extremely low; 200 ships per 10% of naval capacity, which is trivial for a federation to reach by midgame. This makes the Entente Coordination diplomacy tradition (and, I believe some of the Martial Alliance perks, although I never use that fed type) useless, and by endgame can lead to literally thousands of lost naval cap. The upkeep-free (well, not counting fed taxes) nature of the fleet is nice, but 600 upkeep-free ships for thousands of navy cap is not worth it. The Galactic Defense Force does this much better; an alloy tax for otherwise upkeep-free ships. Entente Coordination and comparable Martial Alliance perks can either reduce the tax or increase the total size of the federation fleet.
