Krążownik minowy typu Neptun 1925 (1 szt.)
Kolejny w
naszej flocie krążownik minowy. Wprawdzie z zasady do kolonii wysyłam starsze
jednostki, ale z uwagi na większą prędkość i zasięg, tym razem Neptun powędruje na Belitung, a nie
starszy Posejdon. Oczywiście w razie
konfliktu poza Bałtykiem, Posejdon
także zostanie wysłany do kolonii.
Prezentowany
okręt jest dość szybką jednostką o sporym zasięgu. Uzbrojenie jest
wystarczające dla jednostki tej klasy i wielkości. Opancerzenie jest wprawdzie
symboliczne, ale daje przewagę w starciu z lżejszymi okrętami wroga. Mimo
znacznej prędkości, Neptun wykazuje
się zupełnie przyzwoitymi właściwościami morskimi. Wszystkie tory minowe
znajdują się wewnątrz kadłuba, co daje pewien komfort obsłudze.
