Well.... I figure that most of the fuel would be stored forward and aft outside the armored citadel, but still behind the end belts. So while chances might be a little better of a fuel fire, it's effect on the ship as a whole shouldn't be too extreme. Worst case some sort of tank voiding and watering system could be worked in in the misc weight.

Still, we're talking about heavy fuel oil here: it's not the most combustible stuff. I think if the tanks were adequately subdivided it would be no more of a concern than in a large conventional cruiser.

4x140 for main armament, that's short...

Peru did'nt consider serious warship with 4 main guns.
6 main guns are now neccessary to obtain enough hits probability.

Hmm Rocky,

I'm not so concerned with # barrels as the ROF still allows frequent enough splashes to adjust aim. However, having 4 x 140mm means it won't outgun a thing.

It's basically a slow armored destroyer. Against an auxiliary cruiser it may be adequate, but a Q-ship would be better.  Against an actual cruiser, I think a 6" gunned cruiser should outgun and outarmor it, and have the speed to pick an advantageous range.

IF you are going with the 140mm, it should be traded for more barrels and armor, not for a smaller vessel, IMHO. I'd stick with matching or outgunning opposing vessels on a slightly smaller to same size hull.

Ok, here is somewhat the other end of what's been presented so far.
Larger, slow and tubby, robustly armored, an excellent gunnery platform with a powerful battery. A more expensive option than others, but more capable.

The real regret is I didn't get it under 5,000 tons light.  However the design goal is for a faster Cruiser or AMC to have no range at which they have a decided advantage.

Since this likely comes from the Stabilimento Tecnico Triestino architects, the engine tech is a little dated.

That's pretty sturdy, alright.  I like the inclusion of the ram bow as a contingency measure.

Kaiser Kirk

I just like how they look, and at lower speeds why not?
I mean....  who doesn't like a rambo on their side?
Anyhow it's kinda the other extreme from the other ships.

A slightly smaller version, utilizing a simpler engine design and mixed firing. The advantage this has is it can use any port, yet would still be a tough opponent for an AMC or CL.

note : goofed on main guns, supposed to be dispersed, with an amidships mount, not ends.

Well, I am not good at drawing these things out, and tend to go with analogies. I was going to have a smaller secondary suite, but with the width and high BC, it's basically 3 destroyers wide.  Length wise, I'd thik the centerline weapons should work.   Middle destroyer for centerline, wing destroyers for 2ndaries.

Try to get heavy fuel burning ... it aint easy, and probably not even possible without preheating.

It's not that this ship would carry bunkers full of light fuel or gas.

Example :
The GC Jatibonico class is 84m x 8m, featuring 5 guns spots and 2 sets of  torpedo tubes on centerline. Waterline area is 414m sq.

The proposed vessel has 5 gun spots on centerline (albeit longer guns), but no torpedo tubes above deck, is 15m longer and is 14m wider, with  3.9x the waterline area. I'd think the secondary 140mm would fit in that extra 7m to each side.

In my opinion this is a role for the older Audacity class or Sentinelas.

That said, I also think that protected or light cruisers are best stopped by armored cruisers.  My idea would be for a slow armored cruiser, with more than enough speed to keep station on lumbering merchant hulls.  Such ships can then at least defend themselves from other armored cruisers, something a smaller hull would have trouble with.

My concept would be a three-turreted ship, utilizing the 234mm.  As this caliber came to GC from the former IC ships, I'm not sure resurrecting it is the best idea, but I think that  it provides the best caliber option of those offered for this ship.

As an escort, I think such a ship only needs secondaries for self defense, as DD or TB shouldn't be a problem (if they are, they are probably escorting forces this ship won't be able to deal with) and any cruiser should be handled by the main battery.

Not being entirely familiar with the Navalism rules, I've set an arbitrary amount aside for fire control, wireless and margin, though it may be a bit light.

I have also sketched the ship to provide a visualization of the concept.

Hey Rich,

This may have been a role for the Audacity and Sentinela types, but they're all either sold or will be.  Besides, the limited operating range and freeboard of the types seemed detrimental to the mission.

I did research a modern 234mm gun several sim-years back, so could introduce such a model again.

What you've presented is powerful and well armored, but her freeboard in particular worries me  - especially aft.  It doesn't seem compatible with a mission that will take her into the mid-Atlantic.
