The USS New Mexico was the most advanced, and the best protected battleship in the world when she was commisioned in 1918. She attracted a lot of interest from foreign navies and ship designers, especially from Britain. New Mexico is known for her 12x14"/50 guns. In most ways, she was almost the same as the preceeding Pennsylvania class. However, that was not the case with some of the earlier designs. Most of the preliminary designs for the New Mexico had 16 inch guns in either 3 twin turrets, 4 twin turrets, or 5 twin turrets. The 16 inch guns had been designed and tested in 1911, and was considered ready to be put onto ships in 1913. However, the secretary of the navy did not want the ships currently ship classes that were under construction (Nevada and Pennsylvania) to be rendered obsolete with the introduction of 16 inch guns. So the upcoming New Mexico was a repeat of the Pennsylvania, shipping 12x14 inch guns.

First up is the Design #4, which had 8x16 inch guns, and armor similar to the Pennsylvania class.

Very nice work! Does this mean a resumption of the USN BB drawings? :)

Looks like a beginning of a very interesting series. Looking forward to see further additions.

It's possible, I dont have any new sources for the Delaware up to the New York classes. I might update the Pennsylvania, from which a lot on this drawing comes from. I might also do the New Mexico class and Tennessee class. I might also update the Colorado.

The USN had several interesting proposals that were considered. Some of them have been used in my Roman AU and my No Washington Treaty AU. Another interesting fact is that the Pennsylvania class could have been built with 8x15 inch guns.

I have added the USS New Mexico as rebuilt in 1931. I hope you like it, it has taken me the better part of 11 hours to draw.

Fine job :)

Will you draw the mid 40's version too?

Nice work, its nice to see the alternative designs for New Mexico represented.
Let's just be careful the what-if refits don't overwhelm the real never-weres in this thread. ;)

You are correct, however, if I slap on some triple 14 inch turrets, I have the USS Pennsylvania as she appeared in 1931. So in a sense, I have made both a hypothetical refit, and a real life ship.

I have added the Design Number 1 and the USS New Mexico as commisioned in 1918 for comparison. I have also added a wip of the Design Number 103 which has 12x14 inch guns in twin turrets.
