How to apply Doctrine?

[yandrey]

I researched Doctrine which should give me +20 fleet size, but it doesn't. Do I have to manually do it somewhere or is it bug?

[Elitewrecker PT]

It's automatic. But is it 20 command limit or 20 naval capacity?

[yandrey]

Oh, it's 20 command limit. I thought they are the same. So what does that command limit do?

[Elitewrecker PT]

Command limit is fleet size yes, naval capacity is amount of ships before getting increased upkeep. You can't add more ships through the template or merging?

[NixBoxDone]

Command limit is how many ships fit into any one fleet, fleet capacity is how many ships you can have in total across all fleets combined.

Fleet cap is the number on top of your screen.

Command limit is (one of) the numbers next to your fleet in the dropdown overview.

It's given like this for a soon after starter fleet 3/20 (6) - 600
With the first 3 being your current fleets strength in cap, /20 giving you your maximum fleet strength (command limit) and (6) being the strength you have allowed the fleet in the fleet manager (or by merging fleets, loosing ships etc), which the fleet will try to build to if ordered to reinforce.
And the 600 is the fleets estimated fighting strength.

The numbers are technically the same, but you can have fleets totalling your naval capacity in actual strength (soft cap, going over costs you upkeep) but you can only have ships up to your command limit in individual fleets (hard cap, going over spawns a new fleet with the excess).

Federation fleets have different rules.
