Zamęczę Was ;) Oto bowiem kolejne dozorowce pomocnicze,
zaadaptowane z przybrzeżnych bocznokołowców pasażerskich. Jako uzbrojenie okręty
otrzymały po 2 działka kal. 57 mm oraz 1 szybkostrzelne działko kal. 37 mm.
Ponadto, podobnie jak w przypadku poprzednich jednostek tego rodzaju (post z 26
maja) większość dużych okien nadbudówki jednostki została zaślepiona,
pozostawiono tylko stosunkowo nieliczne bulaje.
Dzięki napędowi bocznokołowemu okręty charakteryzują się dobrą
manewrowością. Mają też małe zanurzenie. Przewiduję, że oprócz pełnienia
funkcji dozorowców, będą mogły w razie potrzeby być używane jako pomocnicze trałowce.
A takich jednostek nigdy dość, więc sądzę, że spotkają się z Waszym przychylnym
przyjęciem ;)
PS. rysunek jest autorstwa WhyMe z forum shipbucket, przeze
mnie został nieco zmodyfikowany (przemalowanie jednostki i parę drobnych
detali).
PS2. Za radą kolegi ŁK, okręt otrzymał mozliwość zabierania na pokład 30 min, które są rozlokowane w pomieszczeniu rufowym.
