Austro-Hungarian Project IV Battlecruiser Design

The designers at MTK (Marinetechnische Komitee - Naval Technical Committee), Pola continued to improve the battlecruiser proposals taking into account the experiences gained at the battle of Jutland and in they proposed what is basically a modified Project II battlecruiser:

Larger calibre main weapons are always superior,
anything below 10cm / 4" guns are not suitable against enemy cruisers
Less casemated guns means less holes on the side and thus less danger spots.
Unique among other navies are the adoption of a fully enclosed well armoured (100mm) AA turret mounting the heaviest AA gun of the time a 15cm/50 gun. For it's era this dual purpose gun would be more than enough against the WW1 aircraft and Zeppelins (Anti-Balloon guns as the Austrians called these weapons)

Like on Project II the Project IV design too featured 3 twin 38cm cannons in par with the German designs and to use a standard shell by both countries.

Simply put Project IV is a streamlined and slightly lengthened Project II with no tertiary armament and the introduction of heavy turreted DP-AA weaponry.
If Project II was the Austro-Hungarian Renown, then Project IV is the Renown killer!

The design(s) had the following characteristics:
Dimensions: 230 (wl) x 29 x 8,82m
Displacement: 32.000tons (standard), 36.000tons (full load)
Armour: 40mm Deck, 225mm Belt
Engines: 112.000shp Danubius Steam Turbines, 4 shafts
Speed: 56km/h (30knots)
Range: 16.700km at 28km/h (9.000nm at 15knots) or
5.500km at 56km/h (3.000nm at 30knots)
Armaments:
3x2 38cm/45 Skoda K17 Cannons
18x1 15cm/50 Skoda K10 Guns
4x1 15cm/50 Skoda K18 DP-AA Guns
6x1 53cm Underwater Torpedo tubes

Or here together with a small history on them:

And finally based on the naming conventions of the German and Austro-Hungarian navies, the name of the class most likely be Ersatz Kaiser Karl or Ersatz Maria Theresia the two oldest armoured cruisers of the KuK navy.
