6x 20 inch guns on a 24.000 tons hull?

I could not resist and made a SS repost for the "deadnaut"

burn, em down laid down 1950
DESIGN FAILURE: Overall load weight too much for hull

Displacement:
20.784 t light; 23.232 t standard; 24.062 t normal; 24.726 t full load

Dimensions: Length (overall / waterline) x beam x draught (normal/deep)
(820,22 ft / 780,84 ft) x 131,23 ft x (16,40 / 16,73 ft)
(250,00 m / 238,00 m) x 40,00 m x (5,00 / 5,10 m)

Armament:
6 - 19,69" / 500 mm 45,0 cal guns - 3.846,50lbs / 1.744,74kg shells, 150 per gun
Breech loading guns in turret on barbette mounts, 1950 Model
3 x Twin mounts on centreline ends, majority forward
2 raised mounts - superfiring
7 - 2,76" / 70,0 mm 45,0 cal guns - 10,55lbs / 4,79kg shells, 450 per gun
Quick firing guns in deck and hoist mounts, 1950 Model
7 x Single mounts on sides, evenly spread
6 - 1,97" / 50,0 mm 45,0 cal guns - 3,85lbs / 1,74kg shells, 2.000 per gun
Anti-air guns in deck mounts, 1950 Model
6 x Single mounts on sides, evenly spread
Weight of broadside 23.176 lbs / 10.512 kg
Main Torpedoes
280 - 1,3" / 32 mm, 9,84 ft / 3,00 m torpedoes - 0,242 t each, 67,787 t total
In 28 sets of deck mounted carriage/fixed tubes
Main DC/AS Mortars
24 - 220,46 lbs / 100,00 kg Depth Charges + 500 reloads - 51,572 t total
in Depth charge throwers

Armour:
- Belts: Width (max) Length (avg) Height (avg)
Main: 25,6" / 650 mm 292,82 ft / 89,25 m 13,75 ft / 4,19 m
Ends: Unarmoured
Main Belt covers 58% of normal length
Main belt does not fully cover magazines and engineering spaces

- Torpedo Bulkhead - Additional damage containing bulkheads:
5,91" / 150 mm 292,82 ft / 89,25 m 14,44 ft / 4,40 m
Beam between torpedo bulkheads 124,67 ft / 38,00 m

- Gun armour: Face (max) Other gunhouse (avg) Barbette/hoist (max)
Main: 5,91" / 150 mm 5,91" / 150 mm 5,91" / 150 mm
2nd: 2,56" / 65 mm 0,59" / 15 mm 0,59" / 15 mm

Machinery:
Oil fired boilers, steam turbines,
Geared drive, 7 shafts, 401.640 shp / 299.623 Kw = 43,00 kts
Range 1.000nm at 27,00 kts
Bunker at max displacement = 1.493 tons

Complement:
965 - 1.255

Cost:
£33,081 million / $132,322 million

Distribution of weights at normal displacement:
Armament: 3.615 tons, 15,0%
- Guns: 3.453 tons, 14,3%
- Weapons: 162 tons, 0,7%
Armour: 8.359 tons, 34,7%
- Belts: 5.272 tons, 21,9%
- Torpedo bulkhead: 924 tons, 3,8%
- Armament: 2.163 tons, 9,0%
Machinery: 9.609 tons, 39,9%
Hull, fittings & equipment: -798 tons, -3,3%
Fuel, ammunition & stores: 3.278 tons, 13,6%
Miscellaneous weights: 0 tons, 0,0%

Overall survivability and seakeeping ability:
Survivability (Non-critical penetrating hits needed to sink ship):
37 lbs / 17 Kg = 0,0 x 19,7 " / 500 mm shells or 7,1 torpedoes
Stability (Unstable if below 1.00): 1,78
Metacentric height 19,3 ft / 5,9 m
Roll period: 12,6 seconds
Steadiness - As gun platform (Average = 50 %): 21 %
- Recoil effect (Restricted arc if above 1.00): 0,39
Seaboat quality (Average = 1.00): 0,18

Hull form characteristics:
Hull has a flush deck,
a normal bow and large transom stern
Block coefficient (normal/deep): 0,501 / 0,505
Length to Beam Ratio: 5,95 : 1
'Natural speed' for length: 33,38 kts
Power going to wave formation at top speed: 67 %
Trim (Max stability = 0, Max steadiness = 100): 50
Bow angle (Positive = bow angles forward): 42,00 degrees
Stern overhang: 9,84 ft / 3,00 m
Freeboard (% = length of deck as a percentage of waterline length):
Fore end, Aft end
- Forecastle: 47,50%, 32,81 ft / 10,00 m, 29,53 ft / 9,00 m
- Forward deck: 19,00%, 29,53 ft / 9,00 m, 29,53 ft / 9,00 m
- Aft deck: 18,50%, 29,53 ft / 9,00 m, 29,53 ft / 9,00 m
- Quarter deck: 15,00%, 29,53 ft / 9,00 m, 29,53 ft / 9,00 m
- Average freeboard: 30,15 ft / 9,19 m

Ship space, strength and comments:
Space - Hull below water (magazines/engines, low = better): 222,1%
- Above water (accommodation/working, high = better): 412,5%
Waterplane Area: 71.067 Square feet or 6.602 Square metres
Displacement factor (Displacement / loading): 50%
Structure weight / hull surface area: 1 lbs/sq ft or 5 Kg/sq metre
Hull strength (Relative):
- Cross-sectional: 0,00
- Longitudinal: 0,00
- Overall: 0,00
Extremely poor machinery, storage, compartmentation space
Excellent accommodation and workspace room
Ship has quick, lively roll, not a steady gun platform
Caution: Lacks seaworthiness - very limited seakeeping ability
I cannot stop laughing

133 billion dollars for something that would break apart while still inside the slipway
