Iowa is faster

Iowa

IT'S ANIMALCRACKE!!!!!

top-right corner of the shipyard screen to the left of the HQ button.

the speed of the 2 ships,depends on what type of engine both ship use,but using
the best heavy bb engine,i would say IOWA


plus,i just won an elite engineer sailor from battle,and wonder where to recieve it,it
told me to go to some items window but where?

I would say Iowa

Iowa should be faster, as it was designed as a carrier escort BB, while the Montanas were designed as a slower,
heavily armed uberwtfpwnage dreadnought killer, which would have gone many knots slower than Iowa.

NF wins again in being realistic!

I feel like being nice.

Montana will go 24/40 23/39 with quite alot of bulge.

Iowa can go 25/42 max. However when your crew starts to get fat it will slow down to 24/40.

What is wrong with answering a quick question? That is what forums are for. No
need to yell at someone because they could have dug it out with a lot of searching
when someone else knows off the top of his head.
