Hmmmm...Would make a good unit for future/near future scenarios, for an advanced naval unit - theres a real lack of those.
As for the actual ship, I think It's kinda ugly.
Being flat in the water is interesting, clever perhaps, but with such a wide deck, and most anti-ship missles being able to launch/ come in at a steep angle, wouldnt that not do a great deal for it??
But then again, with all this effort being made to disguise a bloody great ship, why dont they save the money and buy better submarines?
Wouldn't a stealth submarine be , well, stealthier than a great big destroyer?
If a boats supposed to be stealthed to the max, whats the point of it being a ship? Aren't Naval vessels supposed to be imposing symbols of Power, to show the enemy who's boss
If the sub was big enough, couldn't It carry all those missles any way?
Yes, I think it could even be feasible to have helicopter bays inside, if It was big enough.
If anyone was worried about it not being manouevable enough, or too easy to shoot, Isnt anything bigger than a rowing boat easy to shoot these days?
A ship can be shot from the air, the ground (if its close enough), underwater, over water, It can even sink by adverse weather conditions. What do you think Happens if a Flat ship gets hit by a really big wave? Its either going to be tipped over or be crushed by the force of the thing.
A sub on the other hand, Can only be shot by nuclear weapons, very expensive missles, Other VERY expensive subs and their expensive torpedos, or A blatently obvious fleet of destroyers..
If you're hiding something, its usually something not designed to be shot at.
I wouldn't want to put my Millions of dollars worth of missles on something that doesn't think it can stand up for itself, and is too big to hide properly
However for Civ3 it doesn't matter what a current defense secretary thinks.
