New Cruisers for NS

[Desertfox]

Recent losses means there is a need for more Light Cruisers in the NSN.

The Atlantas and Olympias are seeing their last war. That's 12 ships needing replacing. Losses up to date include a further 3 PCs and 1 LC. While the Olympias will be replaced by the Auroras, theres another 14 ships than need to be replaced.

Also recent experience and new foreign ships (DKB Raiders...) have shown the need for Fleet Scouts and Raider Hunters/Raiders. Two new classes will be introduced:

Those cramped quarters won't be too popular with their crews, that's for sure.
That's a whole lot of firepower crammed into those tiny little hulls, though... and speeds that match a lot of the destroyers out there. Wish I could get my cruisers to turn out like that.

[Borys]

Ahoj!
I like the Weasel. The DKB would be better off with them than with their latest proposal.

The Osprey is too small. Not enough armour. Also, poor arrangment of main armament - it it chase things, yet it is configured for broadsides.

Missed that :)
Not that difficult to fix.

[P3D]

Let's increase reliance on imported fuel further.

[Desertfox]

Or lets make sure it's no longer imported... ;)

Not a bad ship apart from its tendency to spontaneously split in two (hs 0,91)

She's based on the Pegasus which have a strength of 0.75. 0.90 is not bad. She's a tad weak, but it shouldnt be a problem in the Pacific, now if she was designed for the North Atlantic...

Those cramped quarters won't be too popular with their crews, that's for sure.
That's a whole lot of firepower crammed into those tiny little hulls, though... and speeds that match a lot of the destroyers out there. Wish I could get my cruisers to turn out like that.

Tiny? Osprey is longer than some Battleships out there. BTW NS is willing to sell the designs if your interested. ;)

The Osprey is too small. Not enough armour.

I cant really make her bigger, as she is to fit between the 1,700 Weasels, and the 5,500 Auroras. Same problem with the armor. And she's Swiss, speed comes before armor, especially in ships less likely to get into combat.

[Borys]

Ahoj!
Your fleet. I'd ditch the Ospreys, and build more Auroras.

Borys

[Carthaginian]

Nice ships, but the Confederate Admiralty is looking at several domestic designs which they believe will suit their needs at this time. Some have as much punch as the Osprey, and are as fast as the Weasel... though they are more expensive.

One (yet to be perfected) could handle 2 Weasel's and is almost 29 knots. :D

[Desertfox]

I want to have something in the 3,000 ton range, and I need to replace the Cods. The Auroras are excellent ships but quite expensive too.

Compared to Aurora this ship is 2,100 tons lesss expensive. Has 3 less 6" guns, and less armor, (2" deck vs 4" blet, 1" deck). She has similar speed and range (10,000 at 15kt!) which are the more important points.


Hows this one? A touch more range, more armor, and turbo-electric drive (Im researching it)

Bump.

Tanthalas, you have four of each, plus four Auroras. But yeah, NS does need alot more medium and light cruisers. Losses among them were especially high during the war.

I had noticed that during my research, with Italy I had a tendancy to use DDs in some traditional Cruiser jobs (but I had so frekin many DDs it wasnt even funny LOL).  atm im trying to work out a table of orginization for each fleet (I figure I need atleast 2 main and a 1 reserve) since the fleet got so torn up in the last war there may be some analisis of what worked and what didnt.

I did the same thing during the war, but that was because I had lost so many cruisers I didn't have enough, so the destroyers had to fill in.

There is an analysis buried somewhere. It not only has NS lessons but also those of the other participants.

BTW do you have the updated OOB for the NSN? I sent a copy to Rocky, but let me look for mine.
