Due to the requirements for steel elsewhere due to the War of the Pacific, work on the schlachtschiff "Ersatz F" was suspended late in H2/07, with 2200 tons of the 21,500 required complete. This consists of 1061.5 tons to the keel, and 1138.5 tons for two of the four required 11,500shp turbines.
With the ship suspended in such an early stage of construction, it was decided by the Admiralstab to reconsider the design, based on the changing geopolitical situation. They came to the conclusion that, as originally designed and laid down, the Kreigsmarine does
not need the ship. While some navies are building battleships that match it, or nearly so, in speed, when it comes to the DKB battleline the ship is
too fast. 23 knots of speed is not very useful when the battleline speed is only projected to be 18 knots for the next ten years, and only 21 even after that. There is also the fact that comparable ships have either already moved, or are rapidly moving to, the 13.5"-14" range when it comes to main armament.
So the ship is over-engined and under-gunned to be a battleship. Many, including the Brandenburgian Naval Academy, have referred to the ship as a battle-cruiser; but the Admiralstab's conclusion is that for that type of ship Ersatz F is under-engined and over-gunned...
Given the needs for war production, the first choice of the Admiralstab was simply to scrap it on the slip, re-using the turbines elsewhere, The second option was to sell off the ship, completing it only to launching and then towing it off to be a nuisance elsewhere. But there is a fly in these ointments. The name chosen for the ship is
Kaiser Wilhelm II. One does not simply dispose of a ship bearing the name of the current emperor.
So a directive was given to the design staff. What can be done to Ersatz "F" without needing to modify the work already done? The selected option drops the speed by nearly two full knots, with the already-delivered 11,500shp turbines being fitted to the outer shafts, and smaller 5,000shp crusing units fitted to the inner shafts; the amount of oil in the bunkerage was also increased. The reduction in boilerroom and engineroom space given by this allows the wing turrets to be moved and consolidated amidships into a single "Q" turret (to use the Norman notation), retaining the eight-gun broadside with two fewer guns total. And the size of these guns is upped, the original design's 305mm weapons being replaced by the 350mm Model 1905 weapon. Space for additional equipment is also added in the superstructure.
***
As I noted, given the fact that the ship is still in a very early stage of construction, and that there are no changes to its dimensions of any sort and the normal displacement remains the same, I am assuming that when work resumes on the ship in late 1908 it can be to the new design, with the difference in $ being paid at that time.
The design given in quotes is the original. Following that, the revised one.

The speed of the ship is not compatible with anything in your fleet. The 23kts could at least operate with your battlecruisers. And 23kts is faster than most older ACs.
It would stick out more from the Kaiserliche Marine than the old design.
True, but it will fit in better with this...

...and the 350mm armament is now considered essential. I could try 6x350 and speed as-is, I suppose, but this is the preferred option.
(I actually hosted a HSF planning meeting in my head last night. Unfortunatly the details escape my keyboard finger but this was the decision...although KWII himself would have preferred 6x350 and 4 or 8x240 in the same arrangement as
Scharnhorst. ;) )
Besides, I pity da foo' who sends an armoured cruiser up against this puppy with any combination of armament and speed. :D
I'd think making 15" cemented armor plate is not too trivial. You will have to build new factories just to make that. And 6 guns might not be considered adequate. Barbette is paperthin compared to the belt - and I saw many barbette hits in the battles I simmed.
I pity the DKB merchant that was hunted down by the 15-year-old 23kt AC that got away from your brand new 21kt battleship.
Well I'll see if I can fit 6x350 on Ersatz F and still keep the speed up. (Just remember, if that ship was to be named anything but Kaiser Wilhelm II, it would be broken up on the slip without question...)
On the other ship - perhaps it has a 350mm belt and a 30mm decapping plate? ;) Or I could try reducing its armour to 350mm and increasing the barbettes - although down that road lies madness...
Oh yes - forgot to mention - that 1914 design (...by which time there will be at least one new factory...) is heavily based on one by vonderTann on the battlecruiser board, so kudos and thanks to him. :)
Removing two you will have to redesign the ship completely, and include some additional ballast - the ships was designed with that 1000t weight amidships. And I don't like the weight rearrangement of the turrets. I'd say scrap what is on the slipways - and you would be allowed to reuse 1.5BP of the invested 2.2, not the usual 15% (turbines and part of the Shiffbaustahl). And start with a new design.
We'll slide a new ship under the nameplate then. ;D

This ship could only be docked in one single drydock. I Don't consider it a good idea. If you won't insist on 24kts speed it can be quite a few thousand tons smaller.
And there are not too many lvl3 drydock in he Indian/Pacific oceans either.
The DKB can build only battleships or battlecruisers...and has decided upon the latter. So <24 knot = no can do, die Linienschiff ist kaput. (Note that "slightly used, one careful owner, only sailed to the fishing grounds and back on Sundays", and "new foreign model" ships are, of course, always possible).
However, while the "conventional" schlachtschiffen are to be built no more, kustenpanzerschiffen are something that (a) are needed and (b) are cheaper. A "Sverge" type ship would be just what the herr Doktor ordered. Or, perhaps, something like this.

That is just a recast of an elder BB.
for coast defence, go for the smallest hull with the 2 350mm turrets and only a few small cecundaries, diminish speed as far as possible, and use the left over weight to build DD's or even TB's
Agreed. They're bigger guns, but still pre-dreadnoughts. Let the remaining DKB pre-dreads (and, if need be, the new French quasi-pre-dreads) do that job; focus future construction on top-of-the-line stuff.

Very nice, but too slow I'm afraid - 18 knots is required to fit in with the exsisting battleships (the ex-French ships will be re-engined after the war).
The 15 kts is enough to get from port to port.
It is a defensive unit, not ment to chase or run.
With what kind of ship would you attack this little bruiser? A full sized BB? An BC? A fleet of cruisers?
A fleet of Long Lance armed Destroyers, it's worked before. ;D

Quite true; however the Admiralstab is insistant that the CDBB be able to keep up with the 18-knot "battleline".
This is likely to be the final design, and makes use of (one of) the turbines built for the Original Ersatz F:
- 11,500shp turbine on central shaft; speed @ 11,500shp: 17.64 knots (564 tons)
- 2 x 1,250shp cruising turbines on outer shafts; speed @ 2,500shp: 11.58 knots (122 tons)
- total 14,000shp on three shafts; speed @ 14,000shp: 18.55 knots

And after all that...
late January
Hohenzollernhaus, Neue Brandenburg
"Your highness," the Admiral bowed before the Kaiser. "You asked to see our plans for the ship that is to bear your name?"
"Indeed. What have you for me?"
The Admiral spread the plans on the table. The Kaiser looked them over, and frowned. "This is not Ersatz F."
"No, sire. Given the economic constraints of the war and the desire to fit 350mm guns to match the Orangemen's calibre, it was felt that a complete redesign was in order."
"With only four main guns."
"That does seem at first glance to be a regression, sire, however our tactical planners believe that the older type of battleship still has a future as a coast defense ship."
"The name of Kaiser Wilhelm the Second is to be applied to a küstenpanzerschiff?"
"Yes, sire."
"That is not acceptable. What happened to the plans to re-arm Ersatz F with the larger cannon?"
The Admiral was starting to sweat. "The design mounting eight 35-centimetre guns required a reduction in speed, making the ship too slow to operate with the schlachtkreuzers, but still with excessive speed for the existing ships - "
" - three of which now serve as fish havens - "
" - and the six-gun design, while retaining the speed, was considered to have a potential for structural weakness in the centre section, given the removal of the wing turrets and their not being replaced by a Q turret."
"And so you want to build two ships of 10,000 tons each instead."
"Actually only one, sire, economics..."
"That is completely unacceptable!" The Kaiser looked ready to erupt.
"Sire?"
"As the ship is to bear my name it is only natural that I approve the design. Which is seemingly the only thing you have done right here. I hope that the hull of Ersatz F has not yet been scrapped?"
"No, sire, that was to start in mid March - "
"Complete it instead."
The Admiral boggled. "Sire, that still has the economic factor - "
"You were planning on rebuilding these French ships we bought, yes? Scrap them instead. Between them and the Norman ships that closes much of the gap, yes?"
"Yes, sire, but - "
"No buts! Unless you want yours to be roasted over an open fire. I would rather have a fast ship with a large number of small guns than something with a small number of heavy-hitters that is smaller than a breadbox and can't get out of its own way! Build the ship as it was originally designed and as it has been built to date. Oh, you can fiddle with it enough to fit in the Deutenden Stock, but no more."
There was only one thing to say when the emperor laid down the law. "Yes, Kaiser."
Ersatz F was laid up from late 1907 to the end of 1908. Although the Kaiser directed the Admiralty to resume construction on the ship in January 1908, the unfortunate reality of the war meant that priority had to be placed on repairing existing vessels and building up the rapidly depleted torpedoboot force.
On the positive side, this gave the Admiralty time to watch the war unfold and make some back-of-the-napkin design changes they thought might benefit Ersatz F once in service. Specifically:
-The hull has been bulged for protection against torpedoes and mines (though the midships turrets remain vulnerable points).
-The deck armor has been increased in thickness, since the Swiss have developed a nasty habit of dropping bombs (and occasionally airships) from above.
-The tertiary armament has been up-gunned to 105 mm, which experience with Scharnhorst demonstrated to be a useful anti-torpedoboot weapon.
The end result is that Ersatz F, to bear the name of the current Kaiser, is relatively large for her armament, but should be a sturdy and resilient ship suitable for dealing with Swiss, Maorian, or other threats.
Original design specs can be found at the top of the thread. As built:
