i have several suggestions for improvements to the existing warships. 1) i find it strange that an Aircraft Carrier costs fewer production shields than other warships, like a Battleship or AEGIS Cruiser, especially when you consider that WWII wuz the end of the era of the battleship, and the aircraft carrier became the most deadly surface warship. so my suggestion would be for the devs to use the WWII-style "flat-top" carriers from the Conquests WWII scenario and make them available in the regular campaign, raise their production cost to at least the same as Cruiser, or perhaps a Battleship, and give them a 4 plane capacity. then make the current Aircraft Carrier the most expensive surface warship (perhaps 50-100% more expensive than a Battleship) and increase its plane capacity to 8. naturally, the Flat-top carrier would have lower Attack/Defence/Movement ratings than the modern Aircraft Carrier too. 2) the Nuclear Sub should be the most expensive warship, period. an Aircraft Carrier is like a Greek Trireme compared to a Nuclear Sub. and a single Nuclear Sub carrying a Tactical Nuke is more powerful than any Aircraft Carrier fully loaded with bombers. so at the very least a Nuclear Sub should be equally expensive as the 8-plane Aircraft Carrier i proposed, but should probably be ~100% more expensive than that. 3) it's a shame that there's only the WWII-style Submarine and the Tactical Nuke-carrying Nuclear Sub. i think there should be a Hunter-Killer Sub, with better A/D/M ratings than the both of the regular sub, and would specialize in, what else, hunting and killing opposing subs. considering that nuclear subs are faster than any surface warship, if an AEGIS Cruiser has an 8 movement rate, than a H/K Sub should have a ~10 movement rate. also, regardless if there's a new H/K Sub or not, Submarines should either upgrade into one of the advanced. also, the Nuclear Sub should have better A/D/M ratings than the regular Submarine. 4) advanced warships should be able to carry Cruise Missiles. i think it should work as follows: Destroyer = 1 Cruise Missile (CM) Cruiser = 2 CMs Battleship = 3 CMs AEGIS Cruiser = 4 CMs Nuclear Submarine = 2* CMs * - Possibly the Nuclear Sub could carry either 2 CMs or only 1 Tactical Nuke. 5) Transports should be able to carry Tactical Nukes, but they wouldn't be able to launch them. also, if advanced warships were given the ability to carry Cruise Missiles, than a Transport should be able to transfer the missiles it carries to those ships AT SEA, so they can be fired by the warship. however, Tactical Nukes could only be loaded aboard a Nuclear Sub in a city's port. 6) perhaps add a Missile Frigate ship, which could be an upgrade to the standard Frigate. failing the ability to load Cruise Missiles onto all advanced warships, perhaps the proposed Missile Frigate could be loaded with CMs instead. or perhaps the Missile Frigate would simply attack with its own missiles, which would be roughly equal in attack power and range to a Cruise Missile. however, the Missile Frigate would only have the "view" range equal to an AEGIS Cruiser, so it would need a spotter to attack targets out of its visual range. 7) regarding a submarines Sneak Attack ability, i think if there is a opposing submarine in the enemy's ship stack, the sub should have to defeat that sub first before it can sneak attack its target. for example, if you have 2 Subs and the enemy has a stack of 2 Battleships, a Carrier, and a Sub, if you want to destroy the Carrier, you have to defeat the enemy Sub first. basically you couldn't sneak attack the Carrier at all until the Sub wuz destroyed. so your first Sub would attack and destroy the enemy sub, thereby using up its attack that turn, and then your second Sub could sneak attack the Aircraft Carrier. this is far more realistic, because an attacking Sub couldn't get anywhere near an Aircraft Carrier while it's under escort by a defending Sub, therefore it should have to destroy it before it could attack the carrier. 8) after researching the Tech that allows you to produce Marines, you should gain the ability for ANY military unit to attack directly from water, however they would incur a significant attack handicap, perhaps -50%, for doing this. perhaps only non-vehicle units could attack from water, like Infantry or TOW Infantry, NOT Tanks or Modern Armour, etc. also, regardless if non-Marine units can attack from the water, a Worker should not be able to prevent a non-Marine unit from moving onto the land square it occupies, thereby preventing players from using Workers as blockades from water attacks. 9) i've come up with a NEW IDEA, which is a Repair Ship. we all know that the defender always is at an advantage, but this is never more true than in naval warfare. the defender can use their ports for shelter and repair, whereas the attacking ships are totally exposed and incapable of self-repair. i propose a Repair Ship, or some type of mobile ship repair facility, which would enable you to repair your ships away from your city ports. it would be similar to the Sub Pens used in WWII by both sides to refuel and repair submarines and U-boats. it would be similar to an oil rig, a slow-moving facility, perhaps with a maximum movement rate of 2, and would have no attack or defence abilities, just like an artillery unit -- and therefore could be captured by the enemy.
