Niszczycieli nigdy dość… Kierując się tą zasadą, admiralicja
postanowiła w obliczu zbliżającej się wojny zarekwirować 4 okręty tej klasy
budowane w naszych stoczniach dla Wenezueli. Są to średniej wielkości
jednostki, o wyporności ponad 900 ton, uzbrojone w 3 działa 102 mm i 4 wyrzutnie
torped. W porównaniu do posiadanych już niszczycieli mogą wydawać się krokiem w
tył, ale myślę, że nie należy wybrzydzać, tylko brać co jest dostępne :) W
trakcie działań wojennych z pewnością się przydadzą. Dzięki tej czwórce, stan
niszczycieli w naszej flocie sięgnął co prawda poziomu 51 jednostek, ale
pamiętać trzeba, że część z nich to już niezbyt nowoczesne okręty 300-400
tonowe z końca XIX w., nie do końca odpowiadające już wymogom pola walki. W tym
kontekście uważam nowe jednostki za cenne wzmocnienie.

Shells per gun, main battery: 200
4 - 21,0" / 533 mm above water torpedoes
Machinery:
Coal fired boilers, steam turbines,
Hydraulic drive, 2 shafts, 22 598 shp / 16 858 Kw = 30,50 kts
Range 3 170nm at 15,00 kts
Bunker at max displacement = 349 tons (100% coal)
Complement:
83 - 108
Cost:
£0,134 million / $0,536 million
Distribution of weights at normal displacement:
Armament: 13 tons, 1,4%
Machinery: 504 tons, 54,9%
Hull, fittings & equipment: 178 tons, 19,4%
Fuel, ammunition & stores: 224 tons, 24,4%
Miscellaneous weights: 0 tons, 0,0%
Overall survivability and seakeeping ability:
Survivability (Non-critical penetrating hits needed to sink ship):
202 lbs / 92 Kg = 6,2 x 4,0 " / 102 mm shells or 0,2 torpedoes
Stability (Unstable if below 1.00): 1,96
Metacentric height 2,1 ft / 0,6 m
Roll period: 7,9 seconds
Steadiness - As gun platform (Average = 50 %): 26 %
- Recoil effect (Restricted arc if above 1.00): 0,06
Seaboat quality (Average = 1.00): 0,26
Hull form characteristics:
Hull has rise forward of midbreak
Block coefficient: 0,474
Length to Beam Ratio: 10,02 : 1
'Natural speed' for length: 16,55 kts
Power going to wave formation at top speed: 70 %
Trim (Max stability = 0, Max steadiness = 100): 50
Bow angle (Positive = bow angles forward): 2,00 degrees
Stern overhang: 0,00 ft / 0,00 m
Freeboard (% = measuring location as a percentage of overall length):
- Stem: 15,45 ft / 4,71 m
- Forecastle (14%): 15,45 ft / 4,71 m
- Mid (19%): 15,45 ft / 4,71 m (7,48 ft / 2,28 m aft of break)
- Quarterdeck (9%): 7,48 ft / 2,28 m
- Stern: 7,48 ft / 2,28 m
- Average freeboard: 8,96 ft / 2,73 m
Ship tends to be wet forward
Ship space, strength and comments:
Space - Hull below water (magazines/engines, low = better): 187,9%
- Above water (accommodation/working, high = better): 56,1%
Waterplane Area: 4 873 Square feet or 453 Square metres
Displacement factor (Displacement / loading): 46%
Structure weight / hull surface area: 23 lbs/sq ft or 111 Kg/sq metre
Hull strength (Relative):
- Cross-sectional: 0,49
- Longitudinal: 0,69
- Overall: 0,50
Hull space for machinery, storage, compartmentation is cramped
Room for accommodation and workspaces is cramped
Ship has quick, lively roll, not a steady gun platform
Caution: Lacks seaworthiness - very limited seakeeping ability
