It would probably only go to level 3 with the hp increasing 100% each level, with faster speed (maybe 50% each to double at level 3?) , longer range (around 12.5% each), and fire rate (12.5-25% each)
This would make the navies less mirco intensive and less desposible
#Upgradeable ships

yea but how would this work though, do you upgrade ships individually or all ships take the same level? which do you upgrade for the ship, the ship itself or the port?
