Basically the Montana with one less turret and more speed. Hull form differs from the historical Iowa since it doesn't have the beam restriction of the Panama Canal.

Updated the Springsharp, forgot to include the super heavy 16" and fixed the freeboard.

Impressive!

Call me Capt Nit-picky, and I'm sure it probably changes the sim very little, if at all, but I count 16 Quad 40mm instead of 15 and only 34 20mm instead of 36.

Very scary overall though. Nice job Canis...looks like you've not lost your touch while you were away.

Nice! And named after my home state, too!

I find it odd that the USS Texas is now the smallest battleship in the fleet...

Looks mostly like the proposed King/Nimitz changes to Kentucky and Illinois. Nifty.

Is so small. So very small.

(technically, New York likely displaces less at the moment)

Everything's supposed to be bigger in Texas. Perhaps we should try to bribe Canis to Scrap the Texas and have him build a pocket battleship called Texas. As long as it is smaller than the current one. *runs away*

Very impressive indeed.

I wonder why you use an upper belt. ISn´t the USN the inventor of the all-or-nothing?

Another thing - Why are funnel and bridge build togehter. It makes my eyes hurt but the real problem is, that vibrations from the funnel can transfer into the bridge tower. The ship is far from cramped, so why take that risk?

I still wonder why the USN relies on the 16"/50. Of course, we all know it is an awesome weapon and OTL the USN could expect to rule the world with it. There were no bigger caliber guns around in the world (intel reports on the new japanese ships spoke of 16" too). But in WesWorld things are different and it is no secret there will lbe plenty of modern BBs with bigger guns. Why would the USN allow her battle fleet to fall behind?

Cheers,

I dislike guns larger than 16" because I think the disadvantages outweigh the advantages. You get fewer guns, shorter barrel life, little deck penetration, etc...
http://www.navweaps.com/Weapons/WNUS_18-48_mk1.htm

The design is based on the King/Nimitz design. I'll fix the AA goofs. Texas will probably be ending her career in the near future, or at least becoming a training ship to replace New York, with New York replacing Arkansas as a target ship. The four Montanas will probably replace the Nevadas and Pennsylvanias when they complete, depending on the world situation. These would replace the New Mexicos when they complete in the mid 1940's.

I definitely agree to stick with the 16". Larger does not mean better.

What about a longer caliber gun?

Increases barrel wear rather sharply for these bigger guns.

The concept was essentially a proprosal to complete Kentucky and Illinois to a modified design, with some adjustments in armour, a loss of a knot in speed, and a similar superstructure consolodation as was done with the Fargo and Oregon City classes to improve AA arcs.

As for barrel size, Canis is making a similar decision I made with the Excelsiors; I considered 16.5" and 18" guns, but decided the RoF and smothering effect from 12 15" was a beter value.

Main Belt covers 83 % of normal length Main belt does not fully cover magazines and engineering spaces

probably mm's

Tweaked it some more. I kept the armor scheme identical to my Montana design. Several references describe an upper belt when describing her armor scheme. I don't see the point of a 3" belt and it could easily be ignored w/o changing the weight/build time.

A 3" belt on the ends would be useful to prevent splinters and small caliber hits at the waterline impairing her speed.


I'm laying down something similar a year later:

Yes, I'm an N2 Rule fanatic.

On that sketch Shin posted, it does look as if funnel and bridge are connected. So will you keep that feature? Despite vibrations it might also be an issue when manovering at low speed in windy areas. Such structure acts like a sail and will cause some drift.

Well, I figure the Iowa had that same feature with its forward stack. I seem to remember reading that it had something to do with preventing vibration in the director.

California, Tennessee, West Virginia and the South Dakota's all had that feature and I don't recall any issues being noted about vibrations.

N2 rule?
