Admiralty M, UK AUS RN RAN Destroyers laid down 1918

Displacement:
        917 t light; 946 t standard; 1,048 t normal; 1,125 t full load
        Loading submergence 127 tons/feet

Dimensions:
        271.40 ft x 26.30 ft x 10.40 ft (normal load)

Armament:
        3 - 4 " (102 mm) (3 Main turrets x 1 guns)
        1 - 1 " (25 mm) AA
        Weight of broadside 97 lbs (44 kg)
        4 - 21 " above water torpedoes

Machinery:
        40,331 shp steam turbines, oil fired boilers = 34.00 kts, range 6,400nm at 10.00 kts

Complement:
        92 - 119

Cost:
        £0.262 million / $1.046 million

Distribution of weights at normal displacement:
        Armament: 12 tons, 1.2 %
        Machinery: 632 tons, 60.4 %
        Hull, fittings & equipment: 272 tons, 26.0 %
        Fuel, ammunition & stores: 131 tons, 12.5 %
        Miscellaneous weights: 0 tons, 0.0 %

        Metacentric height 1.0

Remarks:
        Caution: Hull subject to strain in open-sea
        Hull space for machinery, storage & compartmentation is extremely poor
        Room for accommodation & workspaces is cramped
        Ship has quick, lively roll, not a steady gun platform
        Caution: Lacks seaworthiness - very limited seakeeping ability

Estimated overall survivability and seakeeping ability:
        Relative margin of stability: 1.22
        Shellfire needed to sink: 192 lbs = 6.0 x 4.0 " shells
        (Approx weight of penetrating shell hits needed to sink ship excluding critical hits)
        Torpedoes needed to sink: 0.2
        (Approx number of typical torpedo hits needed to sink ship)
        Relative steadiness as gun platform: 30 %
        (Average = 50 %)
        Relative rocking effect from firing to beam: 0.23
        Relative quality as seaboat: 0.22

Hull form characteristics:
        Block coefficient: 0.49
        Sharpness coefficient: 0.33
        Hull speed coefficient 'M': 8.17
        'Natural speed' for length: 16.47 kts
        Power going to wave formation at top speed: 76 %
        Trim: 81
        (Maximise stabilty/flotation = 0, Maximise steadiness/seakeeping = 100)

Estimated hull characteristics & strength:
        Underwater volume absorbed by magazines and engineering spaces: 203.4 %
        Relative accommodation and working space: 54.5 %
        (Average = 100%)
        Displacement factor: 35 %
        (Displacement relative to loading factors)
        Relative cross-sectional hull strength: 0.59
        (Structure weight per square foot of hull surface: 34 lbs)
        Relative longitudinal hull strength: 1.15
        (for 9.64 ft average freeboard)
        Relative composite hull strength: 0.63
