Looks like it might be a bit fragile. What will its duties be in the Danish Navy?

3

Tuesday, August 23rd 2005, 2:32am

I like it. Mostly.

The one boggle I have is the main gun calibre. You've got 6" on your earlier CL, and going to 6.1" not only makes them ineligible for the treaty (as it stands, if you join, etc.), it also complicates your logistics. Considering how tiny a difference it makes firepower-wise, I'd just stick with the 6".

Deck space is okay for the number of weapons, I trust?

4

Tuesday, August 23rd 2005, 6:44am

I like her too, allthough I'd try to get her hull strength higher. I agree with Rocky, stick with the 6" gun and keep your logistics simple. Have you tried a 3x3 layout?

After your "Damn, I wanted to post the first drawing of a Dido type layout!!", I was certain that your next cruiser would be a Didokyrie.

Definitely better to stick with 6"/152mm guns. Lose the transom stern. Got any 140mm guns? Then 10x140mm in Dido arrangement.

Do Danish loggies <ever> get the right ammo to the right ship??

A lot of these are on older vessels and are being phased out, as for the 155mm, this is the first ship I have done in metric, but I reverted to imperial when I realised was 3 feet too long for my type 2 slips, but I didn't spot the error on the guns. It will be corrected!

No, but I think if I go for a Dido-esque layout, she will be carrying 125mm dual purpose guns.

Why lose the transome?

The guns are twins, simmed as triples (Greek type) so she is only carrying 10 X 130mm not 15 as shown.

A lot of these are on older vessels and are being phased out

I would certainly hope so. At least it is not as bad as with the Filipinos. :-)
No wonder their ships blow up!! XD
On Didokyrie...

Quoted

Main Belt covers 112 % of normal length
Main belt does not fully cover magazines and engineering spaces
Space - Hull below water (magazines/engines, low = better): 115.8 %

Error or deliberate?
BTW, if I am not mistaken you use 152mm/6 inch guns. You plan to use 152mm/5.98 inch guns as well? :-)

I assume the belt reflects how long it'd have to be if there were ten guns, as the Commodore intends, rather than the fifteen the program thinks there is.

All of the variants look okay. Didokyrie might or might not be crowded for deck space. Didokyrie trades a greater rate of fire and shellweight for reduced range and penetration. Whether this is good or not depends on whether you've got a specific mission in mind or just want a general purpose ship.

You do have sufficient hull strength in all three cases to raise the freeboard a bit; the improved seakeeping might be useful.

Even altering it to ten guns and adjusting the magazines, the main belt still does not cover everything. The magazine for 15 guns is 150 shells per gun, but since it is a 10 gun ship, I assume that it would become 225 shells per gun. If 150 shells per gun for the 10 gun version is correct, then it does cover everything, but for a DP main gun you'd probably like more shells. According to Navweaps, Dido's had 300+ shells per main gun.
... of course Dido's a late 30s design...

DIDOkyrie...take 2!

With most of the raised points covered...I think!

As for a mission, I was thinking of her as an escort for the Tyrs when they enter service (2 per BB), and for any future CV's that get built.

P.S. Walter, the difference in the 6" gun sizes is down to whether you choose to set the gun size in Imperial or Metric, it's down to the conversion software in SS as far as I can see!!

I know that...

... cause it's a deliberate remark. I just thought it was funny when I was looking at all your designs that with some of them you used metric and with some imperial.
