Wheeler Beater??

[mentat]

The CSA Wheeler design certainly turned some heads - very striking design and very capable for Long Range Strike and Reconaissance,  something most Naval powers have an interest in

- have been thinking the design is rather hard to beat - and so far there seem to have been some me toos but nothing to beat it...

So - being up for a challenge - have been thinking - trying to reduce Freeboard/Seaboat + Range - see if can trade for bit extra speed (maxing shp) + firepower - here is first result ...

  - and a bigger option - 160k shp (when available) giving 33.6 knots , 8 x 11" - for a decisive edge in firepower and more armour - good against 9" - trade-off on Seaboat (under 1.0 - but measured at 33+ knots) - but I think 20' average freeboard is perfectly respectable

   - a biggish investment with no TDS - but very capable  ;D

  Does it beat Wheeler ??

[mentat]

- the bigger option - described above - oops ...

The second design might benefit from trading a bit of speed for a wider belt or heavier deck armor, but it's a powerful cruiser.

I like the Duquesne - although she lacks a certain vitesse  ;)

Not sure about the Combat + Airship Hybrid - what are Pros + Cons of 2 separate ships instead??

also, these 33+ knot designs are yummy but very expensive - anyone actually planning to go this far?

[maddox]

Dusquense's  30 Kts speed isn't as fast a DD, but, why would she need it? Her speed is so, nothing big enough to harm her has a speed advantage.
And her 275mm guns will ruin any cruisers day, unless it's a big battlecruiser. The French 140mm is also a very unfriendly one to meet for light cruisers or DD's.

[Kaiser Kirk]

I've been tinkering with this.  Two triples forward, airship mast/pad aft.

Interesting. I would think for airship deployment and recovery, a premium would be placed on seakeeping and stability.  Also, if the intended cruise speed is 10kts, that is well within the realm of where a surfaced sub at the limit of visibility can scoot ahead of you, and the design, while large, lacks a TDS of any sort.

[The Rock Doctor]

Seakeeping, stablity, and steadiness are good, though not "awesome".

The cruising speed is not necessary ten knots - I keep it as the default so I can compare to my older work. 

Mentat - adding the blimp mast to the ship only adds about 250 - 300 t.  Building a cruiser to handle a blimp separately would be at least 3,500 t based on my existing unit, so the combo is more efficient (which is not to say more effective - the Colombians are just on a blimp bender at the moment.  I'm currently sketching a combination airship carrier/first-generation aircraft carrier as a result).

[mentat]

The Blimp Carrier - yo I recognise a fetish when I see one  ;)

Seriously - the tonnage may be pretty trivial - but deck space is more serious - and i would have thought a decent Merchant ship conversion would do nicely for trials - followed by possibly an older cruiser conversion or adapt from CL Hull - I don't see it requiring a dedicated large Combat ship

the Airacraft/Airship Carrier - is  more interesting - the 2 roles are very complimentary - interesting to explore the practical details - good luck, tally ho etc etc

Duquesne - yes she has plenty enough speed to keep out of the way of 28/29 knot Fast BBs / Large BCs - but 30 knots is not enough to run down 29+ knot Cruisers - which is probably majority of recent + esp. Future types

- so in future environment I see her value as somewhat limited ... - heavyish recon yes, raid/prey on convoy yes - gobble up fast cruisers - not really - needs more vitesse
