Everything is getting bigger; subs (us next ssn class), frigates, destroyers, etc. it's a trend everyone is moving towards since it's a little trade back of speed for increased weapons, bigger sensors, etc. for subs, the bigger you are, the more you can isolate vibrating equipment.
Well this is curious. I remember seeing news a while ago this year that said USN was thinking about a "Large Surface Combatant" too instead of Arleigh Burke flight 3.
Has 055 set a new standard for large destroyer / guided missile cruiser now that everyone is trying to replicate?
