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

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

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

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.
