1914 KKK small cruisers

[Borys]

Ahoj!
With the army rebuilt, attention has turned to the navy. In order to remedy the topheavy character of the navy, and replace the 1912 Balkan War loses, three ships will be laid down. Two at Malta, in July and September, and one in Pola - in September.

The ships are repeats of the 1909 Marie Theresie class, with some improvements due to progress of technolgy in the intervening 5 years.

Overall survivability and seakeeping ability:
   Survivability (Non-critical penetrating hits needed to sink ship):
     3 405 lbs / 1 545 Kg = 31,5 x 6,0 " / 152 mm shells or 0,8 torpedoes
   Stability (Unstable if below 1.00): 1,14
   Metacentric height 1,9 ft / 0,6 m
   Roll period: 13,6 seconds
   Steadiness   - As gun platform (Average = 50 %): 70 %
         - Recoil effect (Restricted arc if above 1.00): 0,39
   Seaboat quality  (Average = 1.00): 1,20

Hull form characteristics:
   Hull has rise forward of midbreak
   Block coefficient: 0,507
   Length to Beam Ratio: 8,86 : 1
   'Natural speed' for length: 19,75 kts
   Power going to wave formation at top speed: 62 %
   Trim (Max stability = 0, Max steadiness = 100): 58
   Bow angle (Positive = bow angles forward): 0,00 degrees
   Stern overhang: 0,00 ft / 0,00 m
   Freeboard (% = measuring location as a percentage of overall length):
      - Stem:      25,00 ft / 7,62 m
      - Forecastle (25%):   17,00 ft / 5,18 m
      - Mid (40%):      17,00 ft / 5,18 m (16,00 ft / 4,88 m aft of break)

      - Stern:      16,00 ft / 4,88 m
      - Average freeboard:   17,20 ft / 5,24 m

Ship space, strength and comments:
   Space   - Hull below water (magazines/engines, low = better): 124,7%
      - Above water (accommodation/working, high = better): 90,8%
   Waterplane Area: 11 507 Square feet or 1 069 Square metres
   Displacement factor (Displacement / loading): 101%
   Structure weight / hull surface area: 72 lbs/sq ft or 353 Kg/sq metre
   Hull strength (Relative):
      - Cross-sectional: 0,90
      - Longitudinal: 2,70
      - Overall: 1,00
   Hull space for machinery, storage, compartmentation is cramped
   Room for accommodation and workspaces is adequate
   Ship has slow, easy roll, a good, steady gun platform
   Good seaboat, rides out heavy weather easily

[The Rock Doctor]

A good idea, and the design itself looks solid.

Now hoists of wing guns are armoured, and belt thinned 0,05 to compensate.

This would be a good thing.

Are the beam guns en-echelon, or "side-by-side"?

[Borys]

Are the beam guns en-echelon, or "side-by-side"?

Neither :)

They are on the sides of the superstructure, as in the OTL inspiration:

Ah, okay.  Nice looking ship there.
