Niszczyciel Huragan - 19.10.2010

Po dobrych doświadczeniach z typem Grom, dwa kolejne niszczyciele tego typu postanowiono zbudować w kraju. Okręty, pod które położono stępki w 1939 r., wg niektórych informacji miały nosić nazwy Huragan i Orkan. i miały być lekko tylko zmodyfikowaną wersją Groma. Ja proponuję okręt o zwiększonej wyporności, którą spożytkowano na dodanie ósmego działa 120 mm oraz osiągnięcie prędkości 38 w. (tj. nieco większej niż realna prędkość typu Grom). Słaba dzielność morska i nienadzwyczajny zasięg nie martwią specjalnie, jako że okręt jest przeznaczony zasadniczo na Bałtyk.

Overall survivability and seakeeping ability:
    Survivability (Non-critical penetrating hits needed to sink ship):
      490 lbs / 222 Kg = 9,3 x 4,7 " / 120 mm shells or 0,3 torpedoes
    Stability (Unstable if below 1.00): 1,72

    Roll period: 9,5 seconds
    Steadiness    - As gun platform (Average = 50 %): 26 %
            - Recoil effect (Restricted arc if above 1.00): 0,23
    Seaboat quality  (Average = 1.00): 0,27

Hull form characteristics:
    Hull has rise forward of midbreak
      and transom stern
    Block coefficient: 0,526
    Length to Beam Ratio: 10,17 : 1
    'Natural speed' for length: 22,45 kts
    Power going to wave formation at top speed: 74 %
    Trim (Max stability = 0, Max steadiness = 100): 50
    Bow angle (Positive = bow angles forward): 18,00 degrees
