She's a pretty spanky lil' thing.

About the only thing I'd question is the number of 57 mm guns. How do things work if you trade in eight for two more of those 155 mm (I'm thinking a 3-2s-3 arrangement...)

I'll give it a try, and let you know!!

Swings and roundabouts, I think!

anyone?

(I think you´re pushing things a bit while squezzing an ARETHUSA-class CL into a hull 2000ts lighter....)

What did we agree on for L to B .........

11:1 extreme max mefinks so shes a tad over. 10:1 is playing it safe.

Damn, back to the drawing board.......

Design rules for us gentlemen...

Quoted

Point 2: Length:Beam ratio.
(as currently proposed)
a) Ships of 8000 tons and smaller => maximum 12:1
b) Ships bigger than 8000 tons => maximum 10:1

So with what we agreed it should be allowed, although it is pushing it a bit.

You´re right of course....

BTW, isn't a draft of 19 feet a bit big for a ship that size?

You know, SS prefers long and slender hulls with a deep draft and small BC (the latter is obviously not the case here as 0,412 is okay for such a vessel). That´s the best way to get much stuff into a small hull.

I wonder about the longitudal hull strength of the design posted by CG. At nearly 12:1 there will be a lot of stress for the longitudal structure elements. What makes things worse here is that CG plans to use turrets/barbets wich "penetrate" the structure deck thus weakening it. Especially if we´re talking triple mounts here. A 155mm triple will have a barbet of about 8m diameter. That´s a rough guess. That´s 2/3 of the ships beam. We know that historically several ships, especially cruisers, had problems with their structural integrity and IIRC most if not all of them had barbets at places where they were larger than 1/2 of the ships beam.

Probably Ian can tell us if SS takes care of barbets interrupting longitudal structure elements. I doubt it as this would depend on the exact position of the barbet relatively to the hull (hull form, bc, beam etc.). So I think it is a matter of taking these things into account "by hand" instead of relying on SS.

With the use of deck mounts which have no barbets you could avoid this problem obviously. However, ammo handling will be much saver in a barbet of course...

Well it is as you said: squeezing an ARETHUSA-class CL + two extra main guns into a hull 2000ts lighter."

Funny thing is that I thought that with my upcoming classes with 8,000 ton cruisers I was pushing the limit a bit when it came to draft, so I intended to give my 6,000 ton cruiser a smaller draft than them. But looking a bit at the Didos and the Atlantas, I thought I was slightly pushing the limit for that class as well. But looking at this vessel, which is 2,000 tons lighter than my 6,000 ton cruiser, I think the 16.6 feet draft doesn't seem too bad.

For a destroyer leader;

- Same guns as the destroyers, so 130mm guns
- Why bother with so much armour?
- 32knts is too slow. 35 would be better.
- A smaller faster ship can do the same job better I think.

You mean something like this. It has a poor seaboat rating, but this is a military vessel. It ain't a bloody cruise ship and it'll make the men tougher. Perhaps 6 guns would be better?

My principal reasons behind the design are as follows

1 - With the current government's limited building policy, I have to squeeze as many hulls out as I can to keep the shipyards turning over (No more strikes please, we're Danish!!)

2 - Gunboats do not a Navy make, so maximising the available tonnage (3000 per Qtr) is a necessity.

3 - Due to the Navy's policy of having "more bang for your buck" they (the design bureau) had to pull out all the stops to get a design that the navy could live with given the current restrictions.

4 - The ship is really (to me, anyway!) a CLL, I just think that she can do both jobs, and with a smaller navy, having specialised vessels rather than multi-role make litle or no sense in my world!

5 - I will probably build version 1 , or maybe something similiar , the second version was just to see if I could get Rocky's idea to work.

Maybe the Danes and the Dutch should work together on their "limited navies". Limited in this case being based on government policies.

Denmark and The Netherlands already have a naval co-operation treaty, the most obvious sign being the sharing of bases in the Indian Ocean and South China Sea

Ok, after a little tweaking, it's going to be one of these two that gets built..........
