Aztec Ship Designs, Pre-1913

[TacCovert4]

Alright Gents, I'm beginning the slog of getting the Aztec Empire, aka Sultanate underway.  Haven't decided on a few odds and ends, but I felt a need to get some designs fleshed out at least in part.  This is the current design for the Aztec light cruiser/ DD leader.  I've got battleships, armored cruisers, destroyers, and a lot of other ships to design in a relative hurry to get the Aztecs off the ground....then I can slowly and carefully consider new designs.

Without further ado:

I'll post some comments in the order I run into things.

1) TDS of any sort on a cruiser of this size is a waste of weight. You dont get enough depth out of it to resist anything meaningful.

2) The 88s in B and X superfiering the 105s at A and Y is unique. Not sure how much I would like being one of the 88's gunners without a blast shield of some sort.

3) The sloping freeboard feels off to me. I would go to a uniform high for the Forcastle and For Deck, and a lower height for the Aft Deck and Quarterdeck. Based on the drawing in Conways, this is what the OTL Magdeburg's had.

4) For a protected deck, its quite thin. I would take the strenght you get back from the TDS and dump it into the deck. 60mm seems about right.

Overall, I think its a good near-contemporary to the Roman Lauri class, but geared to a different environment. Good starting point for sure.
