Title: Ottoman dreadnought armwaving
Post by: The Rock Doctor on November 02, 2015, 09:25:05 AM
So the existing Ottoman battleship is basically an improved historical Brandenburg, or a stretched Braunschweig class ship.  The type has 6x11", a 6" secondary, and a top speed of just over 18 knots.

Come 1904 (at some point), the Ottomans will pick up the basic turbine machinery and the all-big-gun capital ship architecture.  They've already got the improved armor.

My thinking at the moment is that the Ottomans aren't going to go hog-wild with their next battleship class.  They don't need to do the jump from mixed main battery to all-big-gun.  The class won't really be a great leap as Dreadnought was, but more of an incremental improvement.  They may go with all-turbine, or they might do a mixed propulsion set-up.  So what about the main battery?

The weapon itself will almost certainly be a 28cm/45 twin, since I have nothing larger or more advanced.  Layout options are:

-APQY:  Visually, the preceding class with a new section plopped about two-thirds of the way aft.  2 guns fore/aft, 8 gun broadside.  Probably the smallest and cheapest design.

-APQXY:  Dreadnought pattern.  The ship will need to be wider, but the primary visual effect is parking new turrets adjacent to the bridge.  6 guns fore/aft, 8 gun broadside. 

-APQY en-echelon:  So Von Der Tann layout, or its mirror image.  This implies a wider ship with more re-working of the amidships area.  6 guns fore/aft, 8 gun broadside but with cross-deck issues.

-"Pillbox":  so Posen-style, probably very similar in actual design.  Also a heavier ship with a reworked amidships.  6 guns fore/aft, eight guns amidships, with theoretical redundancy on the dis-engaged side (although this only becomes useful if the ship reverses course).  Likely the heaviest and most expensive ship.

Considerations: 

-Still need a good and well-placed secondary given that torpedo-craft are a reasonable threat

-The Ottoman budget isn't huge.  This cuts two ways:  The Ottomans can't afford to build huge ships, but they also can't afford to waste money on half-assed ships.

-The Ottoman ordinance industry may find 10 or 12 guns per ship harder to deal with than 8.

-Similarly, the Ottoman shipbuilding industry may find 4 turbines more challenging to produce than 2 turbines and good ol' VTE.

-The major operating areas are the Med and Black Sea, and MAYBE the Red Sea.  I don't expect a lot of fighting within the Dardanelles or more open oceans.

So where would you give with a design, given the above?

Would the possibility of buying old PDN's and refurbishing them be worth considering?

It's a play-style i tend to avoid, particularly "now" when dreadnoughts are making the newest pre-dreads obsolete.  Purchasing and upgrading a PDN's protection, machinery and armament would likely cost three-quarters of a new PDN - from my perspective, not a good value.

IMO, built super Brandeburg is an economical BP option.

SS to test

=> 3T2x12"/21kts - B&T:270

=> 4T2x12"/21kts - B&T:270

What would be your likes and dislikes from amongst the "must build new ships" options?

Post by: eltf177 on November 04, 2015, 03:47:20 AM
I think the APQY design is the best choice, but you won't have either the numbers or powerful enough ships to do much. This is why I was thinking the PDN approach, you can hopefully afford to buy enough of them and give them enough of a refurbishment to be of some use. They'll be slow and more of a coast-defense fleet but that shouldn't scare your neighbors (although it might give them other ideas... ::)).

I do like Jefgte's idea of a Super Brandeberg - maybe as a new build with turbines and better armor?

This is not quite a stretched version of the last ship, but it's close.  The main belt isn't 4.2 m the whole way, but more like 3.6 metres the whole way and then a full deck higher on the forward 25% (with the raised forecastle).

The 15cm are notionally concentrated at the end of the forecastle and then in a block forward of Y turret.  I think it would logically lead to turreted secondaries down the road, ala historical Italian practice.

Three nitpicks:

1) No TDS; could be a problem.
2) VTE's and Turbines?
3) She's on the slow side...
Title: Re: Ottoman dreadnought armwaving
Post by: The Rock Doctor on November 04, 2015, 10:06:09 AM
Thanks. I believe #1 and #3 are artifacts of our tech rules - the TDS isn't technically possible yet, and the speed is constrained by a horsepower limit on machinery of this vintage.

As to #2, this is me thinking of conservative design parameters - "We'll try a couple of these new-fangled turbines but keep good ol' VTEs in case they aren't as good as advertised".  I think it mirrors historical German attitudes around their early dreadnoughts.

All-turbine frees up 0.05 HS, which would let me shave off maybe 300 t from displacement.

Why not go with something like Espania with 11" guns?

...er, why?  I've always thought of the Espanas as the little outcasts the other dreadnoughts don't like to talk about.

The smallest and weakest dreadnought's ever. Not an experiment I'd want to repeat... :-X

Actually you can do some quite nice things with them in SS.  When I was planing separate battleship and battlecruiser lines I was using a variation of them for my "Dreadnought" types.  Since I have instead just gone down the Battlcruiser line (silly lack of resources) I wont be building them.  Instead I will just build evolution's of my "Armoured Frigates".
