Parthian vessels 1916 onwards

[Kaiser Kirk]

I'm just generally shocked that you can get 12 x 180 on an 8000t hull with a real belt and 30kt.

I was rather pleased to find I could.
The fun part is that I started with an Omaha-based layout, but 180s rather than 6".
That works too.
....I really should take a second look at that. The version I updated to 1926 was good, but unfinished.


But I have several Royal Nissean afloat now, and
so I'm thinking what the next step is.
Hmm, I should post the Omaha 8000t and the 7000t Pouseki versions.
Later...

[Kaiser Kirk]

For fun, the 'Omaha' casement monster version
Still too long for my 160m docks...just. I might be able to shrink that.
But 1.2 seakeeping at 31 knots, with a strong belt and deck,
6x180 fore , 8x180 broadside and 6x 180 stern.
All guns are singles with power assist.

The problem with this one is the highest elevation casements I know are +22.
Extrapolating from HMS Hawkins, that may be good for ~22000m,
...I'd like a little further, but the M&H would have more elevation.

Then not last, but least, a 7000 ton beastie, looking to fit that 'medium' cruiser slot.
While I can get her down to 6500t, it costs 1 knot...and if I'm going small, I do
want a bit more speed. Makes it that much harder to get a couple knot advantage.

Still tinkering with cruiser designs in odds and ends of time.
The Royal Nissean XV moved the casements into twin M&H,
this keeps that, but superimposes one, allowing end-on fire.

This also outslopes the belt from 12 to 15, and extends it down from -1.5 to 1.7, while increasing it to 130mm.
Deck armor is increased from 50 to 55 to ensure immunity to plunging fire at all
expected ranges.
Cruise speed is increased to 8840nm @ 16knots, fitting the Parthian desire for screening forces to be able move about the 14kt battleline for the duration of a 8000nm trip. This translates to over 24000nm at 10knots, or about 1600 at 30knots

The Cost is ....Mount armor is thinned a little for better rotation, and 'P' mount is deleted
dropping the main battery from 12 guns to 10.

This is a very tempting trade off.

Not that it affects the numbers at all, but would stern torpedo carriages not interfere with stern aviation facilities?

[Kaiser Kirk]

Oops- and the weapons layout pic had them sited side aft as "TT".
Easy to fix. Good catch.

Anyhow, I have lots of cruiser designs, but 3 main series versions A-I/J ish/ so 12+variants on a theme.

This is a little different.
Longer than I want, but a try at a float-plane cruiser.
If I build them, I'd mix them in as part of larger cruiser squadrons to give them more search / air denial
ability.
The compromises for it cost me some belt armor, but I was able to keep the deck armor and  cruise range/speed.
She's still go a decent punch and belt.

On ship names - where I've used non-English it's been from a mix of Old/middle (pahlavi)/modern Persian (mainly)
Where I could find Latin alphabet translations.  Then there are some taken from names in tales like 'Kalifern' (mythical land across the sea where Griffens live in mountains past a great valley)  or 'Zemaka' (one of 4 named winds, in this case an East Storm wind).

I have found a middle-persian/pahlavi dictionary, so I'm probably still botching the names, but they should be closer.

Intended to provide a cruiser with a decent "punch"
of fast rotating 180mm guns, but high speed and range..
while also providing a fleet scout role.

This results in guns in "A/B" and "P/Q"  amidships but a aft deck and stern cleared for aircraft handling ala Tone

T

This is modeled by a long foredeck covering 20+45=65% of the ship,
with A/B being "Fore deck foreward", and "P/Q" being "fore deck aft"
This leaves the 35% of the ship aft - 58.8m / 193ft for handling aircraft.

This handling deck is a deck level lower than the forecastle deck, allowing the aft guns to fire over with only shallow elevations to clear.

The stern slopes down to make a ramp, allowing planes to be brought on board more readily.
