Possibly need more funnels.

Possibly need more funnels.

I was thinkin that proly gona add another midships

[Borys]

Ahoj!
Korpen and I keep on sparring on this ... IMO anything over 105mm on such boats is not worth the trouble. For all sorts of reasons, mostly related with ease of handling the ammunition and resulting rate of fire.
In your pic we are looking at a 1500 tonnes or larger vessel. Either the GTB1916 or GTB1918Mob.
Better take a look at the GTB1913 or GTB1916mob.

5" is probably too much at this point.  Most light cruisers and certainly protected cruisers can't stand up to 4" gunfire.  (Rohan uses 4.5" but that is mainly because I didn't plan on a 4" gun, skipping at 1.5" increments in many cases)  3" is the standard destroyer gun with the 4" and up being for the larger (for the time) destroyers until that becomes standard, then the 4.7 and 5" guns become the "leader" type gun and finally the normal destroy gun by the 30s.  At least historically.

you were close its actualy a compilation of several of them... couldnt find one i liked everything on so i butcherd a few to make it look like i wanted it to.

Honestly i didnt either the way i was working my fleet up is 3" is an anti aircraft gun, 5" is anti destroyer guns, bigger is well bigger lol.

[P3D]

2000@10kts would be OK range for coal firing on a 750t destroyer. But not for an oil-firing 1000t one.

5" guns have somewhat lower rate of fire.

[Desertfox]

Not bad, do you take export orders?

[Ithekro]

Looks like you got something there if the speed happy, destroyer heavy, Swiss want to buy this model.

[Carthaginian]

The speed happy, destroyer heavy Swiss just wanna buy it and analyze it to get the tech so they can build even faster ones. ;)

[Desertfox]

Compared to my planned Kidd class, she is faster and has a heavier torpedo armament, but at the cost of less seakeeping and range. If I buy any, it wont be to analyze as I consider the Kidds to be better suited to the Pacific, if I buy 'em it will be in bulk to beef up my DD forces which have taken a pounding.
