New Ottoman Ships, 1900 and onward

[The Rock Doctor]

Possibly; although I'm not sure it'd fit.  I'll poke through my Jane's WW1 for analogs.

[Kaiser Kirk]

To be more respected,
A couple of torpedoes could be add

In my Wesworld version of them, I did add submerged torpedoes (not really on deck place for them), but realistically that was a mistake. They are slow enough that torpedoes would be targets of opportunity at best, and the additional maintenance and cost of adding tubes is probably not worth it. Just my opinion

[The Rock Doctor]

I tweaked the gunboat design so it'd be under 501 t for expedited shipbuilding purposes.  That did have the effect of costing me armor and armament; even a 4x88mm main battery wasn't working, so I ditched the two beam 105s for four 50mm QF guns instead.  Not sure it's a great trade-off, but it's still reasonably well armed for its size.

And with the planned Nile Expedition being launched in 1901, the Ottomans are going to add at least a couple more cargo-carrying riverboats to aid with logistics.  These are mildly-tweaked variants on the previous type.

Also to be built - a group of very small gunboats for forward scouting, river mapping, and such. 

Given that the most likely "opposition" along the Upper Nile would be locals with rifles, four machine guns seems likely a reasonably heavy armament for this purpose

The armor belt is basically a row of bullet-proof steel along enough of the hull to keep the boat from sinking.  Additional plates are added amidships to cover the vertical extent of the engine room.

I still would have a single light artillery.  Either a 47mm 3pounder a 37mm 1pounder.

Yah you are only going to be running into people with rifles but nothing says surrender like unanswered firepower.

Put a little misc weight to cover the gunboat carrying a carriage that the gun could be mounted on and used inland away from the Nile.

Like so? I think the current miscellaneous weight would allow for a carriage - wouldn't way more than a tonne, probably less...

Cross-posted from my "OTTOMGWTFBBQ" thread since I chose to lay down two of these in H1/1901

I don't actually consider this to be "crazy" per se, so this is more a matter of floating a trial balloon and seeing whether a variation gets included in my 1901 program.

The Ottomans have a lot of coastline, much of it along some pretty under-developed land with only minimal transportation infrastructure.  So it's logical that there will be some reliance on seaborne transportation of troops and material in peace and war.

While I've got around a half-dozen large transports for moving a battalion (1000 men) over long distances, there are some cases where the sea route isn't actually all that lengthy - Jiddah to Port Sudan (or its equivalent) is 159 nm, while Izmir to Crete is on the order of 260 nm.  These are day trips; the long-term accommodation of a standard troop transport is overkill.

So notionally, I'll build a handful of "troop ferries", built with one-day accommodation in mind.  That's 0.25 t per passenger, plus 0.5 t per passenger for associated equipment/supplies/heavy guns.  Speed's on the high side for the time period to allow sprints or high cruising speed at reduced power.  It's strictly a port to port thing, no independent ability to land troops or cargo in an amphib operations.

I contemplated something capable of lifting a brigade (5000 men = 1,250 t accommodation + 2,500 t cargo) but figure the amount of time need unload and load all that cargo would be a major time-killer.  So I'm eyeballing a smaller ship that lifts a battalion.  One of these could make a round trip between Jiddah and Port Sudan in a day if the cargo movement was efficient and the engines held up.  A one-way trip between Izmir and Crete would accomplished in a day.  Over a period of a week or two, this allows a good number of bodies to be shifted and may make a difference if there's unexpected trouble with the Ethiopians or Greeks.

[The Rock Doctor]

With the Ottomans actively researching several advanced techs, there's been a lot of debate within the navy about the merits of building major warships before those techs mature. 

On the one hand, it's argued that ships built without these new techs (armor, turbine machinery, newer architecture) will soon be obsolete.  Such ships would be a waste of resources at a time when the Ottomans must expend theirs carefully.  The cash could better be spent on other projects.

On the other hand, it's argued that next-generation ships will take some time to become available in quantity - late model, current-tech ships will have a role to play for some time yet.  There's also the argument that sitting idle is essentially throwing away a year or two's worth of steel (BP) production that isn't otherwise going to find domestic use. 

As for the nature of any major warship, the general consensus is that the first new-generation warships will be battleships, and that they'll suck up most of the construction budget from 1904 to 1906 or so.  Therefore, if new current-gen warships are to be built, they ought to be armored cruisers.  A preliminary design calls for a large ship with six new-model guns (available in the second half of the year), a reasonably powerful secondary, and enough speed that the overall final package would be a match for anything currently afloat.

That design is:

A preliminary design calls for a large ship with six new-model guns (available in the second half of the year), a reasonably powerful secondary, and enough speed that the overall final package would be a match for anything currently afloat.

Six 210 vs. 4 240mm, or 6x130 vs 4x229= less main weapon broadside.
eight 150mm vs sixteen 120mm, 8x45 vs 16x 21 = similar secondary broadside
twelve 88mm vs 37mm - much better tertiary

150mm main & 75mm upper vs  180mm main & 120mm upper = less armor

21.5knots, vs  21knots... inconsequential

So...is she a match for the Guiseppi Garibaldi class ?

[Jefgte]

Instant Boardside is one comparison element.
You could add:
Range
RoF
15mn of fire
mps
...

I note 3000kg survivability for Garibaldi & 5000kg for Ottomans

In the ball park.  Garibaldi's main battery is more efficient, but I haven't got an intermediate caliber handy.

The much higher Ottoman freeboard eats up hull strength, yet it's consistent with German practice.  Given the seakeeping rating is huge, I'm not sure I'll stick with that.

[The Rock Doctor]

If I dump 1.0 m of freeboard, the ship still has great seakeeping and is still wet forward.  Chopping that 16" CT down to 8" also helps.  What was that about?

I'm not too fussy about the upper belt; 120mm wouldn't keep out a 240mm shell any more than the 75mm would, but both should defeat a 120mm shell handily enough.

I can bump the main belt and stick another four 150mm in the secondary.  The "cramped" rating is kind of arbitrary; it goes away if I have only 10 150, but the difference is only about 0.4 shells-to-sink.
