Japanese Ship Designs 1912+

[Kaiser Kirk]

Half the size, 4 knots slower.

Fox,

This discussion has been spread out over several back and forth posts
The last focus was on the physical parameters of the ship.
Which is what you've somewhat changed. Now 20 knots, LB 7, BC 0.5.

The other aspect was your original stated intent was something degunned from a warship scout to a non warship scout.
Which you've relabeled. Unfortunately, if my task is- as the rule indicates - broad enough to encompass intent.

I'm sorry, I bet you're ticked off and frustrated, and that's not the result I want.

I tried to avoid this result by specifying these things
in the first place so we wouldn't go this route of incremental "is this enough" change- which was almost certain to be frustrating.
But you did the incremental route anyhow.

I included a clear statements in the past to specifically indicate
the level of changes necessary to meet that goal.

I said this:

C) I'll say up front - a design ruled non mercantile can not be redeemed by small changes. intent of a design is to produce a cheap warship has been established.

I wanted to be clear that small changes were not sufficient.
I didn't want to play the "made minor alteration, is that enough" game over and over.

At this point, I think there should be a clean break and a clearly different design.
Try something like this : <6.5:1 and 18knots, <=2% armament.

So - easy question...
Is this ship within that?

During the war the Japanese Fleet was commanded from the diplomatic ship Tatsuta Maru at the fleet anchorage. The use of the ship proved successful but tied the ship down from its regular duties. In order to free the two diplomatic ships for their regular duties, the Japanese fleet will build two dedicated ships who will do double duty as hospital ships.

Combining high-priority military command and control functionality and hospital facilities is an interesting choice that Im sure the international community will be thrilled with.

[Desertfox]

Definitely a grey area, but very hard to prove, officially they will be hospital ships and foreign dignitaries will be most welcome to tour their facilities, of course there wont be anything incriminatory onboard in peacetime.

Potential design for 1914. She would be designed to use the guns originally ordered for but not used by the Thonburi class CDS. Capable of taking down armored and escort cruisers and older pre-dreads on a raider role. She's basically a smaller Maya with 10" guns (Kongo layout).

I like 10" guns...dunno why, but I do.
I like the Kongo layout.
The ship reminds me a slimmer, less well armored version of my 1909 Asdar class AC.
I don't get why it's got 3" guns instead of more 5" for a more unified secondary which hits harder...and further.
My Asdars have 120mm & 60mm, but the time for the 60mm is past...I just haven't unbolted them.

[Desertfox]

Volume of fire! But yes especially for this ship, which isn't expected to run into massed MTB strikes, I should get rid of them.

[snip]

27knts feels a little slow, and 84% of normal length on the belt means she cant really take a pounding. The 27knts kinda makes sense given the role, and getting it up to 30knts is expensive. How much does it cost to get a longer belt out of her?

[Desertfox]

Longer belt, couple more 5" guns, no 3" but four 2" gatlings.

One of the four Yodos suffered extensive fire and small caliber gunfire damage to the upper-works at Tablas Strait. Since the Yodos have proven to be not quite good at their job, during repairs (1914) she will instead be converted to an aircraft trial ship. The main armament will be removed and replaced with a flying off platform forward and crane and facilities aft for two aircraft (Curtiss Model F?).

Innovative, I think we are close to the time for some ship-mounted aircraft experiments.

Kirk, how will ships using the 1910 Aircraft/Seaplane Carrier be handled? Are they trials-only ships or might they have some value in combat?
