United States Navy: 1900

OK, did some CAD work and found I should be able to move three casemates per side onto the main deck without hampering the 7" guns to bad.


Blue is the outline of the armor, kind of hard to see. Revised Sim below.

One more that should not ruffle any feathers. These are just repeat Chanucys in every respect aside from shipping 18" torpedoes as opposed to 14.2". Because it was just a change in the misc weight definition and nothing else, I did not bother to make a new sim. They will be known as the Truxton Class rather then members of the Chanucy Class.

Something else to think about. The Spanish Destroyer Pluton was run aground at the Battle of Santiago. Presumably, she would have been available for the USN to examine. The following is an Americanised (and N-verseised) Pluton. I am hesitant to go for this design over the Chauncy/Truxton because of the range. They don't gain that much speed and I have room under the rules to improve the Chauncy/Truxton. Do you guys have an opinion on which is better?

I think the real question is what's the requirements for the N6 USA WRT DD range. That's going to drive your design decisions.
