Parthian Ships 1928 +

Kaiser Kirk · January 07, 2024, 05:37:09 PM

Third, and probably last for today,

The Royal Road Courier cruisers seemed a good idea in 1911.
Lack of established shipping lines, undersea cables, questionable fuel supplies at independent ports, many small navies and pirates, and the critical need to ensure timely and reliable delivery of packages, mail, important personages, and even parts not available in the territories... all argued for these Courier cruisers.

20 years later, those functions are not as critical, and the ships are in need of overhaul.
...and there seems to be a need for a Royal Yacht, as well as a dedicated training cruiser for cadets to learn on.
So Royal Road shall become the Royal Yacht , and Royal Mail shall become the Training Cruiser

Granted, compared to a dedicated, purpose built Yacht, a rebuilt cruiser seems a bit...frugal and terribly pragmatic.
But that happens to echo what I want the Parthian Monarchy to come across as. I may build a more ostentatious one later...

Royal Road - Yacht
Royal Mail - Training Cruiser

With undersea cables well established, and regular shipping routes, the need for the specialized courier cruisers has deminished.

Completed in 1913, the time to refurbish or scrap will be soon (1933).
The decision has been made to explore extending their life and convert them to an official yacht and a training cruiser.

Turbo-Electric drive is used as it is the smoothest and provides large amounts of electicity for any needs.
Steam was chosen as it is more common in the fleet, and so better for engineers to train on.
Further fuel oil is a more commonly available fuel than Diesel at this time. Plus it means the old bunkers can be refurbish but unaltered.

Clever use of older hulls.

TacCovert4 · January 07, 2024, 06:00:09 PM

I noticed that you're going for a higher cruise speed.

Also, ostentatious? Bah. We skipped the gold plate for paint!

Kaiser Kirk · January 07, 2024, 06:03:54 PM

The Royal Roads are actually reducing cruise speed ever so slightly.
The originals were 22.5 knots, meant to dash between Parthian ports 2200nm apart, refuel and move on.

Otherwise, fleet cruise speed has advanced from the 10 of compounds to 12 of early turbines,
and more recently I've been doing battlelines at 14 knots, and ships that need to move around the core formation at +2knots.

I was making a jest after the In Character 'show off' moment of the new Aztec Royal Yacht extolling the virtues of big fuel bunkers, a long sleek hullform, and diesel-electric drives to whip across the ocean at what many ships would consider 'battle speed'.

Kaiser Kirk · January 07, 2024, 06:53:22 PM

Oh I'm sure my frugal and pragmatic comment had nothing to do with that...
But yes, I'm ok with the Parthians not being at the cutting edge of Royal Fashion- for now. You may shame me into action. But for now this is far cheaper than finishing one of my Aria Aristabara Flight Deck cruisers as a Yacht.

It's still an impressive range at that speed. ....but yes, the Royal Roads have been dashing around the world's oceans for nearly 20 years already, just they needed to stop for 4-8hrs to onboard more fuel.

I'm somewhat looking forward to the 1931-2 refurb of the Varyu Raiding Cruisers, 7500t, 30.25knts & 12000@10 in 1911 made them big, fast and long legged for the era, I'm betting they can make a decent cruiser now.

The Aztec Yacht reminds me I need to pay more attention to tonnage of engines vs. fuel.
Usually, the math of a warships engine weight precludes it, but on this I could explore it.
So an earlier iteration of the refurb had Diesel-Elec, but I realized cadets would need steam turbines to work on,

Kaiser Kirk · January 08, 2024, 11:39:47 PM

The two original 'Fleet Supply Vessel' classes were Hawg & Wilde,
I refurbished Hawg in 1919, and did a basic refit on both in 1922-23 refits.
...but I've gone through turns 1919.0-1929.5 and can not find a refurbishment for Wilde.
I did update my various refurbishment dates- found that for the Asabara class...and discovered
I overpaid for the BB-7&8 recons, and underpaid for the BB-9&10 recons. So that's a charge on the 1930 budget.

So in 1930, I'll finally get around to refurbishing the Wilde as, well, they are desperately in need of it.

1930 Refurbishment
1908 Destroyer

The Parthians have been following the Byzantine practice of moving old destroyers to a "Fleet torpedo boat" role.
For the early destroyers, this was simply an extensive overhaul. The 750ton destroyers are felt to have sufficient value to warrant conversion to oil-firing.

Parthia has long been concerned with asymmetric attacks on it's sealanes, or offensive laying closing it's ports...or blocking it's attacks.

To counter that, Parthia first built minesweepers for regular service, establishing a core of trained personnel.
A total of 60 were built, 12 in the original series and then 48 incorporating improvements.

Later, with territorial expansion to encompass many regions, and improvements to submarines, the need for a multi-role auxiliary was identified. So the standing Minewarefare force was bolster by the auxiliary 'Patrol Sloop's, and 100 hulls later, has completed.

The need for auxiliaries to patrol shores and provide law enforcement and commerce roles led to the expansion of the Gunboat force, and the creation of auxiliary units to support that. Too small to be multi-role like the sloops, the 'Gnat' class also features 42 of the 'B' Minesweeper variant.

While the original 12 have been scrapped as too antiquated, the remaining 48 have reached a point where the oldest are wearing out. There is an argument that the 142 minesweeper-capable ships should be enough, but the Parthians still want to have that core regular force to serve as trainers and cadres for the auxiliaries. Plus that gives 190 potential sweeps.

So, here's the refurbishment. I suppose I could stage it at 4 per year, like they were built, but ...I'll do it all at once.

The Mouleks were the last of the 6000t protected cruisers, and I was rather pleased with them.
For a while I considered continuing the design instead of the Royal Nisseans. For every 3 Royal Nisseans I could afford
4 of the Moulek class, which would give me 16 vs. the 12 hulls. Ultimately though the Moulek had 1/2 the broadside of the Royal Nisseans. There are advantages in training and ROF, which might make a Moulek force 'better' for night time or bad weather fights, but under most battle conditions, the Royal Nisseans simply were more effective.

So, only two Mouleks were ever built, and it's time for them to come up for a basic AA refit.

The last of the 1930 refurbishments/refits is the 1906 Podgrasas class. Last of the pre-game protective cruisers, it was deliberately big, fast and heavily armed for 1906. Completed in 1907, it's over due for a refurbishment.

There are two designs presented...in case I change my mind.

The First is what I think I'm willing to pay for, leaves the original turbines, changes to all-oil firing, and revamps the weaponry. The armor- not up to current standards - is left alone. Fast for it's time, now on the slower side... but still a serviceable ship, particularly

The Second is a Tone like conversion, removing the rear mounts to provide for an area to host seaplanes.
That would make it a trial for the Pasbanendag "Watcherbird" concept. But I think I'll just go ahead and lay down the Pasbanendag class instead of rebuilding this to trial the idea.

The 1906 Podgrasas class was powerful when introduced, and so was not a priority for upgrading beyond the 1913 and 1922 fire control refits. However, it is now elderly and in dire need of refurbishment.

As built, the class had a long high forecastle and a low stern.
The decision is made to use this class to trial the 'Watcherbird' concept of a floatplane cruiser with 6 floatplanes to join the scouting forces and take the place of seaplane carriers in supporting the fleet.

To long low stern area thus becomes the aircraft handling region.
The aft centerline guns are removed, but the aft waist gun is retained.
Superstructure is modified.
This creates a clear stern area to allow ramps and rails.
The stern is sloped down, to better allow floatplanes to be brought on board.

My pattern is to build classes for 4-6 years, and then when enough tech has accumulated, or the engines would show a real difference,
start a new Class.

There's nothing particularly wrong with the 1924 Hakma class, its a fine fleet supply vessel.
but it may be time for a slightly updated new version

The name is a conjunction of 'Storehouse' and 'Ship'.

Intended to be difficult for opposing submarine or air patrols to damage or sink.

Designed to Cruise at 16 knots, which means a submarine that is not dead ahead will have difficulties intercepting, being forced to run on the surface at maximum speed for a prolonged period. This will only be doable in calm seas and will make them potentially visible.

This requires 7600 SHP.
Optimally, they would like this to be 1/3 of the SHP, which would put the ship at over 21.3kts, which is more 'expensive' than they want.

However, turbines are quite forgiving of long use at good power, so they put the desired cruise as less than 2/3rds power, so 18 knots.
There is a desire to be able to sprint faster than the most modern subs, so 19 knots is chosen.

Draft is kept less than 7.5m to allow use in more areas.

This concept has been bouncing around for a long time, I think credit to Foxy, or it could be Rocky.
Someone did a hospital ship and I've been meaning to do one.
This is more a 'disaster response' ship.

Meant to have a couple spread around.
At need, they can steam at good speed to a flood/earthquake/<insert disaster>

This is a 1929 version, so a 1930/31 would have a touch more speed or range or misc wt.
I'll probably up the BC a touch to get to 14,880 tons.
14.880 / 4 = 3.72 BP
14.880+9 = 23.88mo = 4 HY Dock clears in 9.552mo, +1 to reset = 10.552, so 1 hull/year.
3.72/4 = 0.93/HY

Curious to see what features folks feel I missed on this one.

Intended to be a vessel to support engineering and disaster relief efforts in the territories, based off the hull of the Hakma fleet support ship.
14,400 - 23.5 months, $0.9/HY

For these, they willl be a Hakma hull, but
fitted with Diesel-Electric engines, and the final fitting out of the non-structural elements and superstructure will be different.

Unlike the Hakma these ships are completely unarmed,relying on the kindness of strangers. They retain the torpedo bulkhead of the basic hull.

The provisions to host seaplanes is retained,

I've done generic hospital ships here, but over at WW I had a couple of disaster relief ships with a well deck and so forth.

Obviously I like the general idea. I'd be curious to see the Parthian risk assessment as to which regions are most likely to require its services.
