If we are giving fleet numbers then I guess I will contribute. I have four fleets of ships at any given time of war, numbered fleets 1-4. Each fleet has 25 ships in total:

5 Aries class ships
2 Carriers
10 Septum class ships 
3 Lahai Class ships 
5 Blackhole class ships
The composition doesn’t differ much from this framework. I have a total of 100 ships in the Septonian Navy, that includes all older models and mothballed ships which are still being used.
