Second Caliphate Speculative Design Studies

[Guinness]

Well, I'm trying to mush the two types together into a fast BB I guess.

Also I'm not sure the Ottomans are wise to even have a battleline right now. The ACs can at least do lots of other stuff. With BB designs now running between 35,000 and 40,000 tons and shipping 380mm guns and bigger, the Ottomans won't ever be able to compete in conventional battleline engagements.

National pride though demands something big get built, so faster ships seem like the better deal.

The strategy against the Crusaders the next time around is unlikely to include either BBs or ACs as major players, frankly.

[miketr]

Perhaps but neither of the Crusaders has built such large ships as of yet.  The Hapsburgs have focused on 10K cruisers of late and Iberia 18.5K and 9K cruisers.  Yes Iberia is going to lay down some new BB's but they are 28K and armed with 350mm guns.  The Ottomans could attempt to match such a ship especially if they build a single unit at a time.

As the former Ottoman budget manager I went down the cruiser navy route myself.  I am not sure if this exact design is the way to go is all.  It doesn't appear to have any big advantage over the big Iberian Armored Cruisers.  Now the design does have a clear edge over the Hapsburg Panzekreuzer's in terms of firepower but you already had that with the previous pair.  Also the Ottomans have a long coast line to worry about perhaps something else in the 150mm gun range or 250mm gun range?

The Ottomans have the Basra Class with 250mm guns and the Furat II Class w/ 150mm.

Hmm... what would this be like with the 11.81'' gun you already have? Using the weight saved on better belt armour.

[Guinness]

I've been kicking around the idea of a light battlecruiser too, but the Ottomans don't have a gun of the right caliber. One could be designed.

Tex: Mike started the Ottomans on the road to researching a "12inL45" gun. At first I played with 300mm, but I really want to use historical calibers, so I settled on a 305mm (specifically the RN 12"L45 Mark X). The difference saves very little.

I'm trying hard here to just think as the Ottomans and not the Ottomans+Mughals and friends. So the primary concerns are the Iberians and Habsburgs and the Russians. Maybe in that context replacing the old outdated battleline makes sense. The Ottomans can't build anything like the current state of the art yet.

Not sure any of these ships are worth their weight in submarines, frankly.

[The Rock Doctor]

I think the Ottomans have to pick either BB or AC to stick with - they can't afford to build meaningful numbers of both. 

What happened to the various pre-dreads and semi-dreads that were in service?  Can any of the ordnance or machinery be recycled into something more effective?

With respect to the BC - there should be enough deck space to accommodate eight single secondaries plus some casemates.  Might be a better idea than delaying the whole ship while its secondary battery is designed.

[miketr]

The Ottomans can afford to build 1 big ship at a time, AC or BB.

As to your BB design its not bad but I think it could do with a little more weight to increase its armor.

Michael

[Guinness]

The two ships with modern 280mm guns entered service in 1910, and are presumably useful. If I wanted to strip them, they'd provide a total of 24 guns...

There are two more Italian ships with 12"L35, which even the Ottomans would have to consider obsolete. If new BBs are built, those two might just get scrapped.

There are two Ottoman built ships with older 280mm guns and two ex-Confederate ships with older 12" guns. The CSA 12" guns were 35 caliber, I expect the Ottoman 280mm are about the same. So they're all obsolete.

So it seems the Ottomans are at a decision point: Build a new eventually 4 ship battleline, or just go all BCs all the time ala their Dutch friends.

[miketr]

Worst case the 280mm weapons would be L40's and 1900 gun tech should be L45's.  Also recall the Ottomans lost 2 ships in the Balkan wars.  The 280mm PDN's yes they could be L35's.

They have their own pair of DN's so thats something to work with even if they are clearly outdated at this point but compared to the Iberians and Hapsburgs they aren't hopeless.

In effect you have 2 DN's with 280mm L45's and 2 AC's with 280mm L45's. Which do you reinforce with the 12"L45 guns?

Either design is good, reinforces the Ottoman's strengths in DD/TB's and gives them more craft to lay mines.

Still the Ottomans have 25 DD's (granted 750 ton designs) and 10 small cruisers as of 1916.  They really can afford to build some larger ships.

OR

If they want more fire power why not build some more small fry?  DD's in the 250 to 500 ton range to make the Eastern Med unfriendly ground.

[miketr]

Another thought the Ottomans have a fair number of older TB's why not covert them to mine layers.

[The Rock Doctor]

There's a good idea...

[Guinness]

Hmm... The oldest class of Ottoman TBs date from 1901 or so. They've got short legs and a slightly idiosyncratic hull form.

Poking at them, I get this, which isn't wholly unsatisfactory. They may still be worth more as scrap though. I don't see the Ottomans needing more than two or three modern dedicated destroyer derived minelayers, but some of these conversions could augment those.

If you scrap all nine of the TB's you get 1.13265 BP for your effort.  I think such young hulls have more value in second line roles.

Blah blah blah blah blah they say on the conference call. So I've fired up springsharp :)

This is an idea for a cruiser designed explicitly for trade warfare against distant enemy installations. I picture her mines would be laid via doors in the stern to minimize the distance they have to drop. The upper belt is explicitly to protect the mine storage spaces. Additionally, in peacetime, I imagine the mine hanger can be converted over to cadet training and berthing spaces.
