she must have that look then because of the centred armament. I mean, the propulsion + main guns of the montana go over a length of 170 meters, while this vessel has it all on 30 meters less, while the engines of the times tend to be bigger. the bigger beam of the montana (giving her 10000 tons more displacement) might give more space for the engines as well, and the additional knot ties that back again...... the montana also had part of her turbines amidships, between the funnels and under the bridge.
EDIT: yep, that explains it. machinery in between the 2 rows of boilers, steam-electric. aft of the boilers are only some motor rooms. interesting!
that said, you have moved the forward funnel a lot more to the rear, which gave me doubts in the first place.
all in all, I have learned something new today

I ask of you to prove me wrong. Not say I am wrong, but prove it, because then I will have learned something new. Shipbucket Wiki admin

I`ve been thinking about a new addition to the fleet. It started out as a more 1920s version of the rejected Scheme A, an early proposal for the North Carolina class, found here: http://en.wikipedia.org/wiki/File:North ... heme_A.jpg. It ended up looking more like the G3/N3 classes. The ship is armed With 9x16 inch 50 Caliber guns on a 256,49x33m hull. It is smaller and less powerful than the Louisiana, but has a shorter armor belt on a shorter hull, which means less weight. The removal of one turret also means less weight, all the weight removed can be added to thicker armor, increased speed and longer range. The ship also has the twin turrets from the Omaha, meaning that the ship can go without casemated guns. A great emphasise has been placed on carrying seaplanes for scouting. The ship can carry five-six Loening OL planes, 4-5 in the hangar, and one on the C turret.
I want to hear some thoughts about the basic design before I finish her up. And a side note, I never intended it to be an "Americanized" G3/N3.
Well, three catapults seems rather overkill, no?
Also, I'd reinforce the secondaries. At least six barrels per side should be expected for a ship this size. Preferably more.
Otherwise, I like it.
Actually, it's a bit of an inspired design. As powerful and probably as fast as an Iowa but the scout aircraft would also be very useful, especially for the time (not a lot of flattops to go around).
