Niszczyciel eskortowy typu Kujawy 1937-1938 (8 szt.)

Niszczyciel eskortowy typu Kujawy 1937-1938 (8 szt.)

No i stało się! Po dłuższej przerwie przedstawiam niszczyciel eskortowy (jak kto woli; mały niszczyciel).

Na temat ogólnych właściwości okrętu nie będę się rozpisywał; „jaki koń jest, każdy widzi” Jednostka posiada bardzo silne uzbrojenie plot, ale dziobowe działko 25 mm zostanie  niebawem zdjęte na korzyść projektowego stanowiska rakietowych bg, (coś w rodzaju brytyjskiego Hedgehog).

Ciekawostką jest pierwsze w naszej flocie wyposażenie okrętu w urządzenie radarowe. Jest to jeszcze dość prymitywny aparat, umożliwiający praktycznie kontrolę przestrzeni powietrznej w zakresie 35-40 Mm. Pomimo wszystkich wad tego urządzenia uważam że, lepiej mieć radar mało skuteczny, niż nie mieć go w ogóle.
