The Rock Doctor

I feel she's a little large for her capabilities.  If you reduce her freeboard a bit (so seakeeping's 1.20 only), you would probably have extra hull strength so the ability to trim belt protection and beam - which would probably bump the seakeeping back up again, but on a lighter hull.

Just sayin'.

If you want to replace S&G as fast battleships, you rather need a 29kts 8x35cm version of what you are currently building for the battleline. If you want to use them rather in a cruiser role, you do not need that much armor - neither thickness not extent (upper belt), you'd save another 3-5000t there.

3,000t exactly. I'll redo the drawing later to add the X turret.

There are not that many ships around that are both stronger and faster. Akagi, 2xMontmedie, 2xRuyter, 2 Orange cruisers, but unfortunately all of them can be expected to show up in the Indian/Pacific Ocean.

However, if you want the ship to fight small cruisers and destroyers (from the end belt I guess you do), I'd prefer 1 to 3kts more speed - 8x11" and 16x5" should be adequate to deal with them.

The RfP for this ship would be something along the lines of the following:

Tonnage limited to 25,000t light or less. Lower is better.

Vessel to act as 'heavy' fleet scout.

Firepower should be sufficient to sweep aside enemy light cruisers and easily dispatch the slowly appearing 'heavy' (7-9") cruisers. 28-30cm(11-12") is the presumed level of firepower necessary, more may cause Cpt and Adm to become 'adventurous' and attempt to bite off more than they can chew.

Armor should be sufficient to withstand up to 9"/23cm gunfire at 12,000yds.

Speed should be at least 28kts to allow operations with existing Moltke Klasse Large Cruisers, more is not disliked, but would be extraneous in joint operations with said Moltke Klasse Large Cruisers.

Range should be at least 8,500nm @ 14kts to allow transit from Neu Kiel to Dar-es-Salaam (approx 7,100nm) without stop with margin for operations upon arrival.

Anti Torpedo boat battery should consist of at least 6 QF guns per side of at least 12cm(4.7") with the 13cm(5.1") being preferred

Mission Profile: Accompany Light Cruisers and Fleet Torpedoboats in advance of main battle fleet. Locate and shadow enemy fleet units. Provide information on fleet composition, course, speed, and heading.

Upon engagement of fleets act as gunfire support to CLs and DDs while deterring enemy CLs and DDs from attempting to press home torpedo attacks.

Occasional Independent Operations (Station ship) are not expected, but not out of the question at this time.

This will come as a surprise to no one, but I think a super-heavy cruiser 2/3 the size with higher speed would be a good fit for this role.

At any rate, why not consider a raised forecastle instead of flush deck, and maybe even a reversion to the classic German sided midships mounts?

They'll end up as museum ships, monuments to the DKB glory against the Swiss during the Second Pacific War. :)

Not for a while Walter. They're be reclassified as 2nd Class BBs due to their slower speed (24kts), realtively heavy armor (12" Belt) and semi-heavy gunfire (3x2x12") and act as Colonial ships at Hai Phong, Nord Indokina and Vasco de Gama, Goa.

Bad ships to choose for that role. Scharnhorst was chased like a scared puppy into Japanese sanctuary by two 'inferior' ships (barely avoiding spontaneous combustion in the process), was out-dueled by a 5k ton coastal BB in Alaska, and ended the war in a drydock after having the superstructure completely burned out by a zeppelin. Then again, no German ship had success in the war. Well maybe Gneisenau, in that she avoid being humiliated and damaged.  ;D
