I'm aware she's slower, but I like the layout and the firepower much better. And for 9,000t she's pretty nice if I do say so myself.

She'd be alright as a scout or raider.  I'd be tempted to replace all those 3" and 4" with a few 6", though.

Pic's pretty - there's no missing Wes' influence.

Definately Wes, alright. But as to the secondaries/tertiaries. She's 24kts for a reason. Let me know if ya figure it out. ;)

Get a third turret on the ship, it won't cost you much. Perhaps with weakening the deck armor to 1.5". Orange has three old ship like this (larger, 4x8" but only 22kts) and their utility is limited.

Ahoj!
The mass of 4" are unnecessary. This ship should not be running into masses of torpedo boats. It is a "county" equivalent - so I agree with more 6".
Or maybe make a mini-Bluecher - 4x2x7,5"?

But I designed her to tag-a-long w/ Isla de Pascua AS a torpedo boat screen.  And the "County Class" reference is alot closer than you know.

I'll second the layout suggestion; that middle turret is dead amidships.

I like that better than the original - she could be effective either with Isla de Pascua or on her own, really.

johnestauffer

I have always been concerned about main batteries located so close to machinery spaces.  The magazine for the midships turret will require refrigeration to keep cool.
I guess there are advantages to spliting up the main battery/magazines, but there appear to be some issues with that type of arrangement.
