As far as I remember Marek was after full size BB's, probably ala La Luna or Tyr.

Dumnezeu & 1 other

Designed by using the Russian warships presently assigned to the Black Sea as a bench mark, also, in consideration of what would be required to give the Turkish BB Osmanieh, a run for her money.
The Main battery is a new design of gun, and turret, the gun, the 340/50, may eventually go to sea on a new class of Super-Cruiser Killers, while the 1,400lb heavy shell is destined for use in Coastal batteries.
The Secondary battery is a standard set of 130/50 DP guns in lightly armoured mounts with hoists.
The Medium, and light AA batteries are standard Romanian units, as in service on the Vz31 type destroyers

If sourced as Diesel powerplant could be used in place of the Oil fuel boilers, and turbines presently planned for.

Ansaldo from Italy can offer this design.

It was historically proposed to Sweden but rejected for being too large.

Not just large, but UGLY!

Marek's plans for Romania included 2 BB and 2 CDBB. Romania is further ahead than Poland in their building schedule but that Nordmark design is tempting for the BB for Romania. Still I prefer building 2 CDBB before tackling the BB for Romania.

RD- run the numbers of the Ansaldo design as maybe a future Polish project.

I never understood why such a small country with such a small navy needs BBs or even CDBBs at all......?!

Agree. The CDBB make more sense, at least for Romania. For example I go with more MTB and small ships for Yugoslavia, the two CDBB for coastal protection for Romania and maybe just one BB for Poland as a prestige thing. IMO the need of the Polish fleet now is AA ships to escort those two CA with their weak AA protection.

I'm sure this could be fine-tuned in Springsharp to yield a slightly more optimal design.

This is a design out of a private Indian yard. It's been designed with the philosophy that a CDBB is a mobile strongpoint and defensive platform - therefore, armor and firepower trump speed.

Picture a Shah Jahan class battleship; cut out the midships portion with one funnel and the aviation facilities, and scrunch the two remaining halves together. With the secondary guns concentrated on the beams amidships, that's about what she'd look like.

Stumpy, laid down 1935

Length, 170.0 m x Beam, 30.0 m x Depth, 7.2 m

Approximate cruising radius, 4000 nm / 15 knots

Typical complement: 966-1256


Estimated cost, $41.960 million (£10.490 million)

Remarks:

Ship has slow, easy roll; a good, steady gun platform.

Good seaboat; rides out heavy weather easily.

Magazines and engineering spaces are roomy, with superior
watertight subdivision.

No more than 15,000t should be nice and don't have to be too fast, the Indian design is on the right tract in regard to protection and weaponry but too heavy for the intended purpose.

Impressive indeed but while I don't mind having large turrets having all the main battery in one turret doesn't seem to me like a good idea, even for Romanians. :D

Could you try with two dual turrets?

Yeah. I'm not too happy about that idea either. Originally I had a 3x2 layout, but I wanted the "steady gun platform" which resulted in a Stability that was in my eyes too low.

Here is something that is sane. Hull fits into your existing type 2 docks. Shallower draught gives extra capabilities in operating in littoral waters.

6 power 305/46 guns are mounted. The twin turrets already exist as well which will enable the price to be dropped considerably.

Also carried is a large armament of dual-purpose 152/53 guns that will make short work of any smaller vessel.

The armour comprises of a 280mm plate inclined at 20° or 30° depending on your preference - depends if you want protection or protected volume. Atop this is a single layer of 130mm deck armour. Underneath is a comprehensive TDS. The tall 70mm bulkhead acts as an internal belt behind the 280mm plate. It should be set back far enough so that no shell or splinters will reach the vitals from the sides.

Went with diesel propulsion using 8x4000bhp units that are already in successful service in Italy. This means quicker response times as you don't have to wait to get a head of steam.

Speed of 22knts is more than adequate for a coastal defense vessel. A high cruising speed is specified for quicker response times. The high freeboard also makes her a good seaboat.
