This is a Destroyer that will propably enter production in 1932
I design the ship to to meat the my reqairments of large torpedo firepower and good speed.I tryed to make it as small as posible

Hull, fittings & equipment: 385 tons, 33,3%
Fuel, ammunition & stores: 142 tons, 12,3%
Miscellaneous weights: 15 tons, 1,3%
Overall survivability and seakeeping ability:
Survivability (Non-critical penetrating hits needed to sink ship):
364 lbs / 165 Kg = 9,0 x 4,3 " / 110 mm shells or 0,3 torpedoes
Stability (Unstable if below 1.00): 1,19
Metacentric height 1,2 ft / 0,4 m
Roll period: 12,0 seconds
Steadiness - As gun platform (Average = 50 %): 70 %
- Recoil effect (Restricted arc if above 1.00): 0,19
Seaboat quality (Average = 1.00): 1,02
Hull form characteristics:
Hull has raised forecastle, rise forward of midbreak
and transom stern
Block coefficient: 0,419
Length to Beam Ratio: 10,63 : 1
'Natural speed' for length: 20,89 kts
Power going to wave formation at top speed: 68 %
Trim (Max stability = 0, Max steadiness = 100): 69
Bow angle (Positive = bow angles forward): 30,00 degrees
Stern overhang: 0,00 ft / 0,00 m
Freeboard (% = measuring location as a percentage of overall length):
- Stem: 21,65 ft / 6,60 m
- Forecastle (20%): 18,37 ft / 5,60 m (17,39 ft / 5,30 m aft of break)
- Mid (50%): 17,06 ft / 5,20 m (10,50 ft / 3,20 m aft of break)
- Quarterdeck (15%): 10,50 ft / 3,20 m
- Stern: 10,50 ft / 3,20 m
- Average freeboard: 14,35 ft / 4,38 m
Ship space, strength and comments:
Space - Hull below water (magazines/engines, low = better): 180,2%
- Above water (accommodation/working, high = better): 57,3%
Waterplane Area: 6 680 Square feet or 621 Square metres
Displacement factor (Displacement / loading): 61%
Structure weight / hull surface area: 29 lbs/sq ft or 143 Kg/sq metre
Hull strength (Relative):
- Cross-sectional: 0,50
- Longitudinal: 2,19
- Overall: 0,58
Hull space for machinery, storage, compartmentation is cramped
Room for accommodation and workspaces is cramped
Ship has slow, easy roll, a good, steady gun platform
At first I wonted to use the name Burza the best ship that ever sailed under the polish banner,but that name is allready used by Swamphen for the 1926 DD also a proud name in the polish navy dosent fit as Błyskawica wose a leader type ship sometimes referd to as a torpedo cruiser so I used a name that hase nothing to do with history
The name comes from an song by Polish band Myslovic.
