KM 1928 BC design

[AdA]

Been interested in admiral Zenker proposed 1928 design for a true battle cruiser.
General specifics are 17500t displacement (empty or standard according to different sources) eight 12'' in four twins and nine 5,9'' in three triples, with high speed (34knots) and protection on similar scale to the Deutschlands.
In short, something between the original invincibles and Fishers "follies".

Would a KM option for say, eight BC of this general type, as opposed to the twins and the Bismarcks and the GZs, or simply a KM option for pure BC rather than Fast BB be useful or Ben worst than OTL options?

I find it interesting that the KM considered such a reversing of the HSF earlier option for building decently armoured BC and considered such a pure BC design, and would like to know if someone had details on the operational logic behind such a concept.

To complement the post above, this ships were one option in a Pre-Nazi KM expansion plan. They allowed for a relaxation of the ToV rules, but might have been thought as as not rising any red flags. They wouldn't be able to engage battleships, and as such wouldn't threaten existing battle fleets, but their obvious cruiser killer potential would allow them to perform other missions, even though they don't seem to have designed for exceptional range.

What was their hypothetical range?

What is their value then? Can't take on battleships but lack the range for good commerce raiding.

Couldn't find a quote. But they were designed to use turbines and have a 34knot speed.

Cruiser killers. The OP was essentially a request for informed opinions on what the KM expected to do with them. If they were a reversion to HSF concepts for use in the North Sea, modernised German type (well protected) BC would make more sense.

Where did you get a source for this?

On line. They are mentioned on several warship sites.

Some plans.

This were essentially paper ships. Given that admiral Raeder advocated operational concepts that required long range for Atlantic operations, these would never be built on his watch.
But possibly Zenker had different concepts, more centred on North Sea and Baltic Ops.
