Time for another Battleship!
This is the DNS Paerau BB-6, laid down in 1933, launched in 1935 and commissioned in 1937. It's sister, DNS Dublin BB-7 was to be laid down in early 1934, but due to budget constraints it was never started. DNS Paerau was the largest and heaviest ship to be built and used by the Denton Navy, eclipsing even the modern day Helicopter Cruisers.
This is a heavy WIP, based on the Dunkerque and Richelieu class of BBs. The main armament at the bow consists of two quadruple 14" turrets. Just behind the main superstructure on the sides will feature 2 double 5" turrets, and at the stern is a double 5" turret flanked by 2 quadruple 5" turrets. This configuration plays heavily on the Dunkerque's configuration, although I changed the 3rd quadruple 5" turret to a double. At the stern will be aircraft handling and along the sides and on the quad turrets will be 40mm AA with 64 guns in 16 mounts.

Overall survivability and seakeeping ability:
Survivability (Non-critical penetrating hits needed to sink ship):
70,740 lbs / 32,087 Kg = 51.6 x 14.0 " / 356 mm shells or 7.8 torpedoes
Stability (Unstable if below 1.00): 1.16
Metacentric height 7.2 ft / 2.2 m
Roll period: 16.6 seconds
Steadiness - As gun platform (Average = 50 %): 48 %
- Recoil effect (Restricted arc if above 1.00): 0.43
Seaboat quality (Average = 1.00): 0.93
Hull form characteristics:
Hull has a flush deck
Block coefficient: 0.680
Length to Beam Ratio: 6.47 : 1
'Natural speed' for length: 26.19 kts
Power going to wave formation at top speed: 60 %
Trim (Max stability = 0, Max steadiness = 100): 50
Bow angle (Positive = bow angles forward): 39.00 degrees
Stern overhang: 5.00 ft / 1.52 m
Freeboard (% = measuring location as a percentage of overall length):
- Stem: 30.00 ft / 9.14 m
- Forecastle (20 %): 22.50 ft / 6.86 m
- Mid (50 %): 31.50 ft / 9.60 m
- Quarterdeck (15 %): 22.50 ft / 6.86 m
- Stern: 22.50 ft / 6.86 m
- Average freeboard: 26.03 ft / 7.93 m
Ship space, strength and comments:
Space - Hull below water (magazines/engines, low = better): 81.9 %
- Above water (accommodation/working, high = better): 197.1 %
Waterplane Area: 57,246 Square feet or 5,318 Square metres
Displacement factor (Displacement / loading): 109 %
Structure weight / hull surface area: 175 lbs/sq ft or 856 Kg/sq metre
Hull strength (Relative):
- Cross-sectional: 0.96
- Longitudinal: 1.52
- Overall: 1.00
Hull space for machinery, storage, compartmentation is excellent
Room for accommodation and workspaces is excellent
Poor seaboat, wet and uncomfortable, reduced performance in heavy weather
I would like to point out that I have no idea about any sensors, directors, instruments, etc. in this era, so any help would be appreciated with that. I'm mainly working off of American systems.
Comments are welcomed.
