Kolejne podejście do tematu szybkiego, małego krążownika. Czy
udane – oceńcie sami, ja sam nie jestem z niego do końca zadowolony. Okazuje się,
że do jakichś ekstra dużych prędkości potrzeba będzie jednak sporo większej
wyporności. Niemniej nie wypada tu jakoś dramatycznie źle - co prawda pływa już kilka krążowników osiągających ponad 20 w., nawet ok. 22 w., ale przytłaczająca większość i tak pozostaje wolniejsza od naszej jednostki. Od poprzednika (Admirał Sierpinek z 1889 r.) okręt odznacza się in plus paroma
cechami – jest nieco szybszy, ma symboliczny pokład ochronny (25 mm), ale największą zaletą
jest chyba uzbrojenie – trzy nowoczesne, szybkostrzelne armaty kal. 120 mm, do tego ustawione w
osi okrętu (nowatorskie rozwiązanie jak na XIX w.!) to w porównaniu z 4 starymi,
wolno strzelającymi armatami kal. 107 mm istotny postęp. No i sylwetka, jak mi się wydaje, jest całkiem zgrabna i elegancka:)

Bardzo ładny, chociaż trochę wolny .
OdpowiedzUsuńDobry okręt. Należy rozwijać klasę małych krążowników. Czepialstwo: czemu armaty nie mają masek przeciwodłamkowych? Na poprzednich krążownikach już były.
OdpowiedzUsuńPrzeoczenie projektanta;) na następnych typach maski znów będą.
OdpowiedzUsuńw okresie PWS byłby z nich kanonierki
