Parthian Ships 1928 +

[Kaiser Kirk]

First Parthian ship post in 3 months !

Looking at HY2, 1929...
I will have completed a whole series of AA guns in 1929.0
I will have started researching primitive DP mounts in 1929.5
I will be finishing an Avio Aristaraba Flight deck cruiser in 1929.5 and a Bazdari flight deck carrier in 1930.0.
I believe that will furnish 3 of the former and 4 of the latter.   That will give 1 of the former to accompany each modern AC duo,
and 1 of the latter for the Atlantic, Pacific and Expeditionary fleets, with 2 for home.

So the rush to meet the minimal carrier needs to provide fighter cover and deny air space control to the foe, will almost be over.

I have many many many needs for BP
...I need a yacht...
...I will need replacement seaplane carriers as my ancient converted torpedo boat carriers are soon to be scrapped.
I have already posted the Seaplane-cruiser meant to take up a Japanese-style reconnasiance role.
...I need to refit the Tiamats for the modern times. That may wait for DP mounts to be available, they won't 'need" it until 1932.

So, I'm thinking the next step from the 'Falconeer' (Bazdari) would be the 'Kestrel',
a larger, faster flight deck carrier, fielding more fighters with a scout-bomber option, able to rapidly launch due to flying off platforms, and heavily armed against light (DD/CL) surface raiders at night.  Knowing DP mounts are being developed, they
will eventually field those.

The step beyond those will be actual strike carriers, as planes in the 1930s make that more attractive.
I rather expect I may field something akin to HMS Glorious - one more flying off deck ship
and then turn to USS Enterprise clones.
Though I have copied Rocky's idea and made a 9000 ton carrier.

Intended as an evolution of the Bazdari fighter carrier.
Longer and faster with a flying off deck to increase
the ability to surge fighters airborne.

The vessel is 'sized' for 33 planes
allowing 2x 16 to be carried.

This woud be 2x Fighter (at first)
and later  1x Fighter, 1 x Scout/Torpedo, when they realize they can't launch 32 fighters before an incoming strike arrives.

OR 2x Scout/Torpedo (in a strike roll)

Concerns over reliability mean the Parthians expect this to be 2 groups of 12 in practice.

In reality this will likely evolve into 1 x Fighter, 1x Scout/Bomber, allowing the rapid launching of up to 16 fighter, but a constant reconnaisance role. 

A single  "mail plane" is carried, with a removable set of seats allowing either critical cargo or passengers.

Flight Calculations
Single Hanger : wp/65

80 tons / plane

12m FD = 2 hanger

Waterplane needed : 55 x 33 = 1815
Waterplane 2540 / 55 = 45 possible.

Misc Wt
33 * 80 = 2640 needed

HAW = 1320
HBW = 1320

Freeboards
It is expected that the 3m deck heights of carriers is in reality 6m lighter structures. Placing the flying off deck at 12m and flight deck at 18m.


Fuel :
Parthian fleet cruise speed is currently about 14knts for 6-8000nm.
Vessels expected to operate in support of the fleet - movng around the main body- have a cruise speed of 16 knots.
This both allows destroyers to sprint and drift in an ASW role, and carriers to move off, launch into the wind, and then come about and catch up with the formation.

Weaponry

Double Stacked Casements along the hanger sides.

The 23mm are on platforms on the 'H" towers.

         37mm&90mm - deck edge
          [ 130mm - upper hanger
          [ 130mm - lower hanger
   6m- |
3.5m- |
1.0m- | Armor deck
-1.5m | Bottom of Belt

Armor
The deck heights place thecrown of the armor deck at a mere 1.0m above the
waterline, with the lower edge at -1.5m
This is meant to defeat HE and SAP rounds from light guns, and preserve the carriers ability to manuever and fight.

The 38mm TDS only 2.1 m inside the hull, which is expected to be insufficient at stopping surface or submarine torpedoes, but should handle lighterweight aerial torpedoes. Even if the bulkhead leaks, it should decouple the shock wave and limit flooding.

So the above vessel is 33 AC and 13750 tons, with two launch platforms and some modest armor and TDS.
The TDS is a little weak, and a good argument could be made for dropping it, and using that tonnage elsewhere,
but otherwise it's a continuance of a theme. With it's speed it can substitute for further Avio Aristarbara and Bazdari vessels.

Comparison is, what about smaller cheaper.
The below vessel is 26 AC and 9000tons - only one launch platform, lesser armanent, similar but very limited armor, and no TDS. Tonnage wise, scaled up to 13750 is 39 aircraft...not much of a gain.

BUT...fully completable in 3 HY.
I may just build one or two to both supplement the Bazdari class and get operational experience with it.

Warning: Beam between bulkheads too wide

Named "Sea Eagle", this is a common name for "Osprey".


Intended as a lightwieght economical alternative to the problem of providing fighter and scout coverage to the fleet.

At 9,000 tons, it only takes 3 HY to build, and is 3/4 the cost of the Bazdari. However, it is extremely vulnerable to raiders.

It has minimal armor and ability to take damage.
A single torpedo, bomb or cruiser shell may cripple it.


The vessel is 'sized' for 26 planes
allowing 1x 16 to be carried.
with 4 flying spares

Plus 4x Scouts
and and 1 spare

Lastly, a mail plane.

For 26 planes

The single  "mail plane"  carried, with a removable set of seats allowing either critical cargo or passengers.

This one is another step up, to 43 Aircraft.
At 16,500 tons it's much larger than the current vessels.
Compared to the prior vessels it's 2.9AC/BP for the Osprey, 2.4AC/BP for the Kestrel, and 2.6AC/BP for this.

Better guns, better armor, effective TDS, flying off deck, more survivable...but more expensive and slower to build.
Very tempting to knock a knot off the speed and free up 400 tons for other things, also adding 0.6m of depth to the TDS, making it 1.5 external and 3.2m internal, for a very respectable 4.7. 
..but then it could not keep up with the Dahae and Avio Aristaraba/i].
I'd like 30-33, but that takes even more tonnage ...argh.

Note : 180m is my floating dock length, I have 190s and some 230s, but 180 allows theoretical repair anywhere, including some bay in the middle of nowhere.

A successor to the Bazdari, meant to accompany the Armored Cruisers if necessary.

Featuring a dual hangers and a flying off deck to allow a better
surge ability against incoming aircraft.

Deck space : 2387/55 = 43 aircraft possible.
43 * 80 = 3440 tons needed

= 1720 & 1720

Guns
130mm guns and  cruiser-level armor is meant to allow it to survive a nighttime or bad
weather attack by destroyers or cruisers.

The 37mm quads are at the corners and middle,
with 4 single 90mm between each set.
Against high angle targets, this matters little,
but it means 2 x 37mm quad can fire directly forward or aft.

This makes 11 gun positions on each side, spaced roughly 15m apart.

The 23mm are on the "H" Towers, two twins on sponsons on each of the 3 'exterior' tower faces,

Guns are protected with light shields for strafing.

Armor

Belt covers from +2.5 to -1.0.
The shallow depth is felt acceptable
as combat is foreseen as short range.

The belt is outsloped 12 degrees
3.5 / cos(12) = 3.58

A heavy deck is fitted for both
splinter protection (up to 240) and to thwart lucky long range hits.

The upper works, save for the Casement enclosures, are unarmored, as an AoN effort.

TDS
The TDS rises to seal to the armor deck
behind the main belt, providing splinter protection.

This adds +24mm to the effective belt thickness.

[Kaiser Kirk]

This is the Bazdari class instead of scaled down to the Osprey, scaled up to 12,000 tons and 29knots, featuring just 1 extra aircraft. 2.8AC/BP   it's faster...but the Parthian battlelines are notoriously slow.
Compared to the 13750 ton version, less side guns, so less future defense vs. torpedo planes,
and with a single deck, lower launch rate of planes- and limited ability to launch and recover at once.

Anyhow, that gives me a couple options to look at my future budget around.

The Bazdari (Falconeer)
is intended to be primarily a fighter launch platform to ensure air control over the fleet, preventing and disrupting opposing spotting
and torpedo attacks.


The actual airgroup is limited in design :

1 Flight (16) of Fighters, with 1 flying spare per talon of 4 for a total of 20 fighters.

One talons (1x 4) of scouts, with 1 flying spare per talon, for a total of 5 scouts

Desired 25 planes = 2000t

With aircraft operations still being in development,
designing the minimum required space is problematic,
so a a larger space is planned, allowing operations to
help verify how much is 'necessary'.

Eventually, the ship may carry 2 flights (32) with no reserves.

Deck Space : 2216/ 65 = 34 aircraft possible
31 x 80 =2720
=1360 & 1360

Sufficient speed to keep up with the Stormbringer Class,
with high cruise speed to move around steaming formation as needed.

A heavy battery of 165mm guns and
cruiser-level armor is meant to allow it to survive a nighttime or bad
weather attack by destroyers or cruisers.

Belt covers from +2.5 to -1.0.

[The Rock Doctor]

I'm not actually sure you'd get a useful hanger on the 9,000 t design if you're integrating casemates into the hull at that level.  Consider how restricted the hanger on HMS Hermes was, with guns integrated into her hull, and she was almost 6 metres wider than your 9,000 tonner.

Larger, wider ships will generally support your design philosophy better than smaller, slimmer ships.

Armoured Casemate Ship

Displacement:
   9,000 t light; 9,279 t standard; 10,185 t normal; 10,910 t full load

Dimensions: Length (overall / waterline) x beam x draught (normal/deep)
   (521.91 ft / 515.09 ft) x 51.38 ft x (25.13 / 26.52 ft)
  (159.08 m / 157.00 m) x 15.66 m  x (7.66 / 8.08 m)

Reduce draught and increase length and beam to have a longer deck useful for parking security.

[Kaiser Kirk]

The 9000 tonner just may have to many compromises.
I was thinking more along the lines of the independence class, but it's still narrower than that of that.

Conceptually, casements have a pivot point supported by the exterior hull structure, which is why they are lighter than deck mounts.
They can also blister out of the hull a bit, taking less space 'inside'.  There still should be the breech, and a hoist and conveyer behind.
So the portion inside the hull should only be a couple meters, but say 2.5 x two sides = 5, remove from 15m... and you're at 10m. That could be an issue.
While somewhat offset by the fact most carriers flared out as they went up, and so are wider at hanger than WL,
...Rocky may have a point.

Draft I wasn't worried about, I was looking to have just enough square meters to fit my airgroup, so traded beam for draft.
I can undo that, but it will cost me speed. Which would make it a smaller Bazdari.

Length I'm not so worried about, as in the late 1920s Parthia's concerned about getting fighter and scout biplanes launched,
not torpedo-carrying monoplanes, and 160 fits my 'cruiser' docks. Even when you look at some Escort carriers they could
still operate monoplane fighters at that length.

I fully agree that my carriers will not "age well", but I really don't think the 1940 planes are foreseeable to designers in 1929.


Maybe I'll look to Honsho as a guide, which was still a couple meters wider.

[Kaiser Kirk]

The Genesis of these was I that I had been considering a carrier in 1929.5,
but I'm doing a series of AA refits then, so I started pulling up 1925-1929 designs and updating them
for 1930 with the current suite of AA.  Since 1930 is this coming weekend... figure it's time to dust them off.

Anyhow, this is the "Osprey" rebranded as the "Seabird",
wider and shallower in draft and the same speed as the Bazadari.

Now that I've explored it, the vessel is just too weakly armed/armored for what I want.
I may build one as a dedicated training carrier, just cause. It would work as an escort carrier,

Warning: Beam between bulkheads too wide

A slower, fatter version of the Osprey.
I don't think I'll name this after a bird this time.
'Drayah Xar' is Sea Donkey - a dependable beast of burden.
Drayahendag should be 'Seabird'.

This broader hull theoretically can hold 2162/62= 33 aircraft
taking 2640t = 1320/1320.

But the most misc wt I can spare is 2480 = 1240/1240
for 31 AC.


Still Intnded as a lightwieght economical alternative to the problem of providing fighter and scout coverage to the fleet.

At 9,000 tons, it only takes 3 HY to build, and is 3/4 the cost of the Bazdari. However, it is extremely vulnerable to raiders.

It has minimal armor and ability to take damage.
A single torpedo, bomb or cruiser shell may cripple it.


The vessel is 'sized' for 26 planes
allowing 1x 16 to be carried.
with 4 flying spares

Plus 4x Scouts
and and 1 spare

Lastly, a mail plane.

For 26 planes

The single  "mail plane"  carried, with a removable set of seats allowing either critical cargo or passengers.

[Kaiser Kirk]

I thought back to a design that when I put it forward in 1926 I was told was too big and advanced.
So...is it too soon for the Charmosh now?

I could fit it into the 1929 lineup.

Right now I'm inclined to put two Kestrel in for both the Bazdari and Avia Aristabara classes,
leaving them at 4 and 3 respectively, which was about how many I wanted of them. That seems a logical successor for my mind-canon.

As a strike carrier, the Sea Fox seems a more logical next step right now, then move to the Charmosh in 1932, but there's no functional reason why I could not lay down the Charmosh in 1929.5. 

Use an Osprey as a training carrier.

For them, the difference between 1929 and 1930 is I have to have a skinnier TDS, as the engine is slghtly larger,
and then skimp on the armor slightly. Which is not desirable. So I'll keep those in 1930 consideration.

I also need to start laying down the Pasbanendag class to take the seaplane carrier role from my old TBCs before they rust out completely.

Warning: Shell weight too light3rd Battery

Named for an mythological eagle-winged dog, which fought for good, and would swoop down and carry off the enemies of Persia.

Intended to be a 'strike' carrier,
flying off a squadron or flight  of torpedo planes
after launching a sweep of fighters to clear the path.

Normal operations would be focused on launching Scoutplanes.

With 4 plane 'Lances'
and 16 plane 'Flights'
and an expected 75% availability,
20 planes are needed per Flight.
For 60 planes total.

The last 5 are intended for flyable spares or admin uses...or something.

Superstructure
The "H" shaped two-island + flying bridge superstructure is fitted,
like the Brits planned...until further wind tunnel tests showed just one
was superior.
I think for Parthia they will make that switch in 1932.

Guns
A battery of guns is fitted in casements on the lower hanger deck,
while a set of AA guns are fitted along the edges of the landing deck.
Each is provided with it's own armor screens to guard against splinters.

A Armor deck proof against cruiser weapons is fitted,

A TDS is fitted, rising to meet the crown of the armor deck.
This provides splinter protection for the belt.

Before laying down a carrier in the spare space, I need to start the AA refits..and working through that cost,
it does not look like I can afford to lay a keel...unless I want to pause coastal defenses, which I could. I seem to always need more BP...

The 1929 refit of the Babr Class focuses on AA ability but updates the ASW as well.
Unfortunately it slightly changes the trim, loosing slow and steady roll at full speed.

1. The 118mm ASW howitzer is removed, a 163mm is put in it's place. This reduces the ammo to 75rounds.
2. Remove the twin 57s and replace with quad 37s   : 7.4+5.1 tons vs. 6.3 + 5.4
3. Replace the 15mms with 23mms : 1.4+1.3 vs 1.8 + 2.8
4. Add 1t stick bombs for the Howitzer.
5. New FC (5.9t) & NF Gear (5.9)
6. 2nd "Y" thrower 1t
7. torps -> 2TT2 21" 4t
8. Misc Wt Resv down to 2t.  0.5 hull, 50.1% machinery
9. Steadiness drops to 69, but can't adjust trim in Basic Refit, slowing slightly gets the 'slow and steady' rating back.

This is an evolution of the Palang (Leopard) design,
boosting gun power while retaining the other elements.
Ultimately this sacrifices the good seakeeping,
but fits in one more 120mm guns, and better provisions for night fighting.

The main battery is aligned in a pair of
two-gun mounts in A and X, with a superimposed "Y"
addressing a perceived deficiency vs. some foriegn designs

In "B" is a howitzer firing blunt nosed shells to allow forward engagement of submarines. For shore bombardment support,additional HE rounds can be stored in the 120mm mag. This mount can easily be replaced by a 120mm gun.

Amidships is an elevated platform between the torpedo tubes, aranged en echelon are the two pairs of 37mm Quad AA. This allows good sky arcs, and good engagement on the opposite broadside

For/aft, Paired twin GAST 23mm - think of a Rifleman battlemech..
are mounted to allow engagement of any plane seeking to strafe the length of the ship. These can also bear on the beam.

All guns are given bulletproof 1/4" (6mm) spray shields.

The Asbara class was recently refurbished and the main guns updated, but the semi-automatic 57mm guns lack the reach and capacity for sufficient burst radius of guns 90mm+ and can not sustain the needed ROF for true utility.
The Parthians have developed GAST 23mm for closein high ROF, and 30 and 37mm for longer range punch.
The Wirblewind Quad 37s fit nicely where the two-gun 57mms were.

The Vazrya Class will join the Expeditionary fleet as they have flag facilities and will carry Shahanan Iskandar and Shirin to her wedding in Azteca, and so is being updated with new AA. 

This created a problem for me, as I needed to use the various Gun tabs for the AA....but I had used one to model communications tubes and armored FC domes.
So I've moved that weight to Misc Weight, the prior design exercise at least gives a validation for the amount allocated being close.
They still exist its just how they are accounted for gets changed.

Frankly I need a 6th gun spot, but don't have one, or else I'd have some 37mm. I expect it will be rearmed again with DP in a couple years, at which point the 90s will likely become 37s.

1929 Basic Refit.

1. Changing how the modeling is done for the  armored communication tubes - from guns to misc wt.
2. Moving weight for Admirals bridge and Searchlight tower to 'above deck'
2. adding hulesmeyer, paravanes
3. Changing climate control from 'Windcatcher' to 'CO2 Compressor AC which I acount as a 0.1% tonnage.
4. moving torpedo nets from HAW to HBW where I normally budget them.
5. replaced 90L50AA with twinned 90L54AA.
6. Added 23mm AAMG
7. Repaid for the double FC 6602*.1 = 660.2 x 2 =1320.4 = 1320
8. 2x Floatplanes, Cat and Hanger

A) While modeling these, I wanted 4 armored communication tubes,

So my 5th gun slot is 4 x 100mm / 150 cal guns- no ammo - and 70mm splinter armor.
Basically proof against any non-AP hit.

They weight 284 tons.

They were to  house the FC directors at the top, and offering
a secure stair from the keel to the upper deck. Watertight hatches would segment the tube.
At the time I figured the double fire control and commo tubes would become 'standard'.

B) I need my 5th gun spot.
So I am removing them from guns, and placing them as on-deck miscellaneous weight.

[Kaiser Kirk]

 I find myself wondering if here- where I lack the gun tabs to add 37mms,
perhaps I should be making the GAST 23mms into single or twin 30mms.

The 30s would actually be much like the USN's 28mm, which was designed with biplanes in mind and had a very sensitive fuse.

Conceptually here, and the Vazrya class, the 90mm battery takes the place of the 37s with bursts at a distance,
Recenty I read that 'barrage' often wasn't so much a curtain all at a set distance, but more a cluster along the future flight path, so the plane would be flying into a string of exploding shells - which makes getting the exact distance and rate of change far less important.

Hmm, maybe I'll add 30s on the cruisers.
