Some Feeback for Unit-Upgrades/Choices:
1.) "Destroyers"
The Destroyer line of ships don't seem to be consistent in their role whithin a navy. Very early on they are the main combat ships, and then gradually change their role to sub-hunter, which is fine. The real deal-breaker starts with the Stealth Destroyer &Fusion Destroyer) which suddely is no longer able to detect subs. The role of sub-hunter suddenly gets transferred to Cruisers. I am very aware that the roles of modern Ships can blur together, but for gameplay's sake, please leave destroyers in their classical role as sub-hunters, 2nd-line ships, patrol-ships, anti-air etc.
Also in addition to not being able to SEE subs...they also defend first against them, and have NO bonus against them.
2.)"Cruisers"
The upgrade-line is simply too messy. The difference between "Cruiser" and "Heavy Cruiser" is virtually non-existant. To make matters worse, they both upgrade to what (IMHO) ist the same type of ship, but gets split in 2 units > "AEGIS Cruiser" and "Missile Cruiser". As far as i understand these are the same IRL (see "Ticonderoga"-class Cruiser). Give them "see Subs" and Missile-transport of 1-2, not 4, which is really overkill. Keep these abilities, making the carry capacity bigger towards fusion-cruiser. Cruisers should be the standard-warship. Perhaps they should also defend first against subs, as they receive a bonus against them (see destroyer > the bonuses don't make sense between cruiser and destroyer)
3.)"Battleships"
Battleships should really come to an end as soon as Missile/Aegis-Cruisers appear. The drawbacks of a heavy, slow ship are just too much for what it has to offer. Just let them upgrade to the Cruiser-line.
4.)"Submarines"
I don't get this line at all. I alway thought IRL there were 2 lines: "Small" hunting subs, which evolved out of the classicals sub. and very large ICBM-carriers.
5.)"Hover Tank"
I don't see the reason/advantage of it.
^^
Please be aware that some of these things really mess up strategical choices you have to make. I upgrade my Destroyers with Sonar, to be Sub-Hunters, and suddenly they don't even have the ability to find them anymore.
