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.
