Machinery:
   Diesel Internal combustion motors,
   Electric cruising motors plus geared drives, 4 shafts, 104.402 shp / 77.884 Kw = 27,00 kts

1914 is still 1912 engines, so the max shp is 80 000.


But it would be much easier to give good feedback on the ships if you write something about what role you see for them, or the thinking behind the design. :)

This goes for all the designs.

Why are there two fairly similar classes in different threads?

They remind me of Washington Treaty battleships, a couple decades early.

That's a lot of 40mm for a time when no vessel fears aircraft, plus

Don't you mean QF for at least one of these two?
And engine year is still 1912.

[P3D]

Apparently the Baltic Navy is not concerned at all keeping sealanes open, or just to scout for the battlefleet.

[Sachmle]

Then it would appear that the best way for one to defeat them would be lots of mines and commerce raiding..... Wonder who has a fleet built for that? Not me, but someone does....
