Machinery:
Oil fired boilers, steam turbines,
Geared drive, 2 shafts, 49 947 shp / 37 260 Kw = 33,00 kts

Bunker at max displacement = 532 tons
Complement:
187 - 244
Cost:
£1,419 million / $5,675 million
Distribution of weights at normal displacement:
Armament: 96 tons, 3,5%
Armour: 44 tons, 1,6%
- Belts: 0 tons, 0,0%
- Torpedo bulkhead: 0 tons, 0,0%
- Armament: 35 tons, 1,3%
- Armour Deck: 0 tons, 0,0%
- Conning Tower: 8 tons, 0,3%
Machinery: 1 283 tons, 47,3%
Hull, fittings & equipment: 781 tons, 28,8%
Fuel, ammunition & stores: 458 tons, 16,9%
Miscellaneous weights: 50 tons, 1,8%
Overall survivability and seakeeping ability:
Survivability (Non-critical penetrating hits needed to sink ship):
755 lbs / 342 Kg = 10,1 x 5,3 " / 135 mm shells or 0,4 torpedoes
Stability (Unstable if below 1.00): 1,32
Metacentric height 2,5 ft / 0,8 m
Roll period: 12,1 seconds
Steadiness - As gun platform (Average = 50 %): 72 %
- Recoil effect (Restricted arc if above 1.00): 0,26
Seaboat quality (Average = 1.00): 0,84
Hull form characteristics:
Hull has rise forward of midbreak
Block coefficient: 0,400
Length to Beam Ratio: 8,57 : 1
'Natural speed' for length: 19,84 kts
Power going to wave formation at top speed: 65 %
Trim (Max stability = 0, Max steadiness = 100): 85
Bow angle (Positive = bow angles forward): 17,00 degrees
Stern overhang: 0,00 ft / 0,00 m
Freeboard (% = measuring location as a percentage of overall length):
- Stem: 21,82 ft / 6,65 m
- Forecastle (20%): 16,40 ft / 5,00 m
- Mid (50%): 16,40 ft / 5,00 m (13,12 ft / 4,00 m aft of break)
- Quarterdeck (15%): 13,12 ft / 4,00 m
- Stern: 13,12 ft / 4,00 m
- Average freeboard: 15,20 ft / 4,63 m
Ship tends to be wet forward
Ship space, strength and comments:
Space - Hull below water (magazines/engines, low = better): 183,5%
- Above water (accommodation/working, high = better): 140,7%
Waterplane Area: 11 131 Square feet or 1 034 Square metres
Displacement factor (Displacement / loading): 70%
Structure weight / hull surface area: 45 lbs/sq ft or 218 Kg/sq metre
Hull strength (Relative):
- Cross-sectional: 0,55
- Longitudinal: 1,24
- Overall: 0,60
Hull space for machinery, storage, compartmentation is cramped
Room for accommodation and workspaces is excellent
Ship has slow, easy roll, a good, steady gun platform
Poor seaboat, wet and uncomfortable, reduced performance in heavy weather
135mm are single porpose.
40mm are polish made
