You know...

I like it.

I know some folks will raz you about the quad 6" guns, but for some reason I find the quad 6"ers rather neat. (I've put together two different 4x4 cruisers with 6" guns and gotten them both shot down... but someday I'll throw realism to the wind and just do it!) The all-forward layout is also kinda attractive to me.

My main comments would be to suggest that you lower steadiness down to 70% and raise stability a tad bit more. On the drawing your bridge also looks a tad too... tall? Big? But then you do state you have flag facilities, and the Japanese had notoriously battleship-like bridges on their CAs.

Seeing as it has the aviation facilities and an emphasis on scouting, I'm not terribly concerned about the comparatively light armor for a ship of this size. After a tad bit of thinking, I'd also like to see that aft 105mm mount raised a bit - the forward two mounts have good arcs, but the lower aft mount could probably benefit from a bit more altitude.

In summary, I like it.

You'll have to wait a few more quarters to see what I'm planning for the Chilean scouting forces.

I can predict what HOo would say if he weren't distractred:

SNAP!!! Ie, she's too long for her beam.


I'm not sure why China would need such a ship, but I'd think a somewhat smaller vessel might be able to do the same job.

Oooh... that'd do it...

She's almost like a Tone-class cruiser, you know. Same length, but a lesser beam.

I was inspired from the Oyodo class

She's almost like a Tone-class cruiser, you know. Same length, but a lesser beam.

And Quad turrets need a beamy hull. Tone shipped twin 8s (probably could've taken on triple 6"), so you'd need something beamier than a Tone, I'd think.

Quads in general, I can find the link to the lengthy discussion for the Manitobas, but long story short, cramming 4 guns into one turret will give you dispersal problems, ROF problems, and " 4 eggs in one basket" problems.

Where's China getting Radar from?

....I'd assume either Japan or German technical assistance?

I echo the concerns about her beam with quad turrets.

a) Are you thinking the beam is now okay for the quads ?

b) It's for the future at present the ship has no radar and with German and Japanese friends shouldn't be a problem to fit it on the ship

Here's the most extensive discussion on Quad turrets in the 6" range on this board (there's probably more over on WPDB)...
http://wesworld.jk-clan.de/thread.php?threadid=3207&sid=

May be i'm blind but i couldn't find a NO-GO for a use of quads on a beam of ~ 18m . PLEASE HELP ME !!!

Well the easiest way is to simply look at historical ship designs. I'd hazard a guess that a quad turret would be as wide as a triple 8" turret so you'd likely need a beam above 60 feet to acomidate the turret with enough hull strength to spare.

The wesworld equivilent would be the Italian Pisa class with a 62.66 foot beam.

wider beam (to fit quads) and greater range

I'd say thats much better. IIRC Gavin stated that the Pisa's were rather weak structurally with their 62 foot beam, which IIRC was why they were converted to CVL's but you have 2 more feet in the beam and 2 less turrets.

The length to beam ratio should keep Stephen happy

An interesting concept. It certainly has its uses for scouting. Perhaps one of the most scout-focused scouts we have in WW?

I'm baised against quads so I won't comment further on them.

isn't the best idea I think. Getting the mass of turrets and armor going 35kts takes lots of power, while the unarmored hangar packed with flammables is a huge risk in surface combat.

I'd divide the two functions - a fast, unarmored seaplane carrier with DP and AA armament and a standard 8x8 6" gunned light cruiser.

China has also a seaplane carrier in the pipe . So we have a pretty good Scouting force with the seaplane carrier and this scout cruiser.

I think is different and that is enough reason for me to built it. Being assigned to this ship on the other hand is another story. Looks to me like a big kaboom on the making.

The trick to using this vessel in combat will be that it REALLY wants to know it's going into combat before combat happens. If it's known that the force it's part of is closing with the enemy, all the seaplanes can be launched, and the flammables in the hangar/catapault area cleared as much as possible (fuel lines purged, ammunition stored in the magazines, etc). Given that, it won't be as safe as a normal cruiser but it shouldn't be TOO terrible a risk. Getting into a surprise night engagement, though, would not be good, but the ship's speed will help there as far as getting the heck away from the area. Essentially, she's about like Tone with 15cm vs 20.3cm guns.

And that's also one of the main reason for me to built it . Btw it's planed that the ship will be laid down at the end of 1938.

And with it's speed of ~ 35kn i think it's fast enough to engange the biggest troubles.
