I want to see SupCom style wet navy in orbit.
T1
Frigate: scouts ground and fights in orbit and can target air units but not ground, anti missile countermeasures
Submarine (renamed to Corvette): deep orbit stealth unit targets orbital units only
T2
Cruiser: bombard unit targets ground and orbit at range with missiles
Destroyer: orbital supremacy unit, strong anti orbital weapons and countermeasures against stealth corvettes, weaker ground attack
T3
Battleship: Heavy artillery platform, high health high damage low rate of fire weaker against stealth units and air unit swarms
Carrier: Large Support ship, strong anti air weapons, repairs and deploys air units.
Nuke Sub (renamed to Prowler): strategic stealth platform, can deploy nukes against various targets
T1 is about scouting and gaining Orbital Control
T2 is about supporting ground troops with light bombardment and securing Orbital dominance
T3 is about assaulting enemy bases
