Russia 1901 Proposed Ships

[Guinness]

The turmoil of 1900 has caused ripples through Russian military planning...

An evolution of existing TB designs:

TB-51, Russia Torpedo Boat laid down 1901 (Engine 1900)

Displacement:
   320 t light; 330 t standard; 369 t normal; 400 t full load

Dimensions: Length (overall / waterline) x beam x draught (normal/deep)
   (214.90 ft / 211.61 ft) x 19.69 ft x (7.38 / 7.80 ft)
   (65.50 m / 64.50 m) x 6.00 m  x (2.25 / 2.38 m)

Armament:
      3 - 2.24" / 57.0 mm 40.0 cal guns - 6.00lbs / 2.72kg shells, 250 per gun
     Breech loading guns in deck mounts, 1886 Model
     1 x Single mount on centreline, forward deck centre
      1 raised mount
     2 x Single mounts on sides, aft deck centre
      Weight of broadside 18 lbs / 8 kg

Machinery:
   Coal fired boilers, complex reciprocating steam engines,
   Direct drive, 2 shafts, 7,000 ihp / 5,222 Kw = 25.95 kts
   Range 2,000nm at 10.00 kts
   Bunker at max displacement = 70 tons (100% coal)
     Caution: Delicate, lightweight machinery

Complement:
   41 - 54

Cost:
   £0.044 million / $0.175 million

Distribution of weights at normal displacement:
   Armament: 3 tons, 0.7 %
      - Guns: 3 tons, 0.7 %
   Machinery: 227 tons, 61.5 %
   Hull, fittings & equipment: 82 tons, 22.1 %
   Fuel, ammunition & stores: 49 tons, 13.3 %
   Miscellaneous weights: 9 tons, 2.4 %
      - Hull below water: 3 tons
      - On freeboard deck: 6 tons

Overall survivability and seakeeping ability:
   Survivability (Non-critical penetrating hits needed to sink ship):
     75 lbs / 34 Kg = 0.7 x 6 " / 152 mm shells or 0.1 torpedoes
   Stability (Unstable if below 1.00): 1.48
   Metacentric height 0.9 ft / 0.3 m
   Roll period: 8.9 seconds
   Steadiness   - As gun platform (Average = 50 %): 57 %
         - Recoil effect (Restricted arc if above 1.00): 0.07
   Seaboat quality  (Average = 1.00): 0.81

Hull form characteristics:
   Hull has a flush deck,
     a normal bow and a cruiser stern
   Block coefficient (normal/deep): 0.420 / 0.431
   Length to Beam Ratio: 10.75 : 1
   'Natural speed' for length: 14.55 kts
   Power going to wave formation at top speed: 66 %
   Trim (Max stability = 0, Max steadiness = 100): 70
   Bow angle (Positive = bow angles forward): 0.00 degrees
   Stern overhang: 3.28 ft / 1.00 m
   Freeboard (% = length of deck as a percentage of waterline length):
            Fore end,    Aft end
      - Forecastle:   20.00 %,  7.87 ft / 2.40 m,  7.71 ft / 2.35 m
      - Forward deck:   30.00 %,  7.71 ft / 2.35 m,  7.55 ft / 2.30 m
      - Aft deck:   35.00 %,  7.55 ft / 2.30 m,  7.55 ft / 2.30 m
      - Quarter deck:   15.00 %,  7.55 ft / 2.30 m,  7.55 ft / 2.30 m
      - Average freeboard:      7.62 ft / 2.32 m
   Ship tends to be wet forward

Ship space, strength and comments:
   Space   - Hull below water (magazines/engines, low = better): 201.7 %
      - Above water (accommodation/working, high = better): 91.5 %
   Waterplane Area: 2,597 Square feet or 241 Square metres
   Displacement factor (Displacement / loading): 17 %
   Structure weight / hull surface area: 17 lbs/sq ft or 85 Kg/sq metre
   Hull strength (Relative):
      - Cross-sectional: 0.50
      - Longitudinal: 1.12
      - Overall: 0.54
   Extremely poor machinery, storage, compartmentation space
   Adequate accommodation and workspace room
   Poor seaboat, wet and uncomfortable, reduced performance in heavy weather

Misc Weights:
3t Below Water: Reserve
2t On Deck: 2 Torpedoes
4t On Deck: Reserve

Trial Speed: 30.5 knots

Looks fine to me.

Makes my 27kt Lampos look slow, though they are much heavier armed.
