Yes, I am doing fleet training. The ships do nothing but train actually, since I have nothing to shoot.
Some of my earliest ships have reached just under 20% crew grade bonus.
Given the numbers in that thread you linked, it also appears I will end up recruiting too many officers, maybe.
And the numbers I calculated were on the old times, before the recent ship build rate increase, so I can build 3 batches of ships per year now.
I'll need 25 academies? Maybe? I could be building academies for an entire year non-stop!
I also forgot to count my escort frigates (which can be built at a rate of 3 batches of 3 per year) and the upcoming designs/shipyards for laser frigate (10 planned), spy frigate (2 planned), light FAC carrier (6 planned), decoy drone frigate (still on drawing board).
Add in coillers, jumpships, gate construction ships, maintenance PDCs, salvage, tankers & resupply, maintenance vessels, ... aaaaa...
And to think I planned for starting the 15 kton cruiser production within 2 years! Which once that starts, will churn out 2 batches of 2 cruisers a year, and add an escort destroyer design!
Might have to put most of that off for the foreseeable future or resort to conscript crews.
