I love the nuclear battleship, they are very good unless you stick them with a stack of 5 BB, then they just get overpowered and the normal ones steal its kills. I don't like the sub, I used mine for attacking large fleets rather than the usual flotilla and it just died. I may have attacked too many ships with it, but I didn't like. I don't really like the sub in general, I prefer surface ships.

I hate them.

If a player is able to play well and wisely maneuvers nuclear battleship - it is unbeatable. There are many tricks. that come with experience. You can kill 100 enemy is not nuclear battleships without damaging its nuclear battleship. But
if you have no experience, and your nuclear battleship just standing or moving in a straight line - it will die instantly as the same as the lost the HMS Hood. Never leave it without supervision. Nuklear battleship is a toy for those who are willing to spend on this game for more than 20 hours a day - and then he alone will destroy all the enemy's surface fleet.

Nuclear submarine has no great advantages over conventional. 2 diesel submarines 3 lvl easily kill a nuclear sub, and nothing you can do about it. My opinion - the nuclear sub useless. It is better to build more diesel submarines.

I like the sub and since there job description is to kill BB, it can essentially cripple an enemy naval to ground capability, but I mostly build surface ships, to keep a hold on the sea.

I really like the nuclear tree, and I tend to use those units almost exclusively alongside their conventional counterparts (which make up the majority of the branch) as a kind of extra punch wherever it's needed. As long as I pay a lot of attention to when and where I field them, these guys have never let me down.

If you get a fleet of every kind of surface ship and send off into the blue, it can do anything. I stalled an invasion and knocked out many sub flotillas with one.

Oh yes, the second form of wolfpacking, after a pack of wolves hunting.

This is what happen when you don't use destroyers as escorts, there pretty good at defending from subs, but never againts other ships.

I always use destroyers.

Good, keep using them.

I don’t think Nuclear submarines can engage cities. However, they are significantly more safe than Nuclear Battleships, since battleships are much slower. I have no clue if a Nuclear Carrier can nuke cities too, but if it can I will surely produce it.

nuclear battleship is faster than nuclear sub tho
so they arent really that muh "safer"
