Ścigacz torpedowy typu ST-25 1932-1933 (12 szt.) i ścigacz artyleryjski typu SA-8 1932-1933 (3 szt.)
Trzecia
„i pół” generacja ścigaczy w naszej flocie. Od poprzedników różnią się nieco
większymi wymiarami, wypornością, szybkością i zasięgiem, natomiast ich
uzbrojenie i ogólne rozplanowanie pozostało bez zmian. Tradycyjnie okręty te
działają w dywizjonach w składzie: 1 ścigacz artyleryjski (przewodnik
dywizjonu) i 4 ścigacze torpedowe.
Jak
zwykle w przypadku ścigaczy, dla uzyskania realnych osiągów musiałem trochę program
„pokantować” Na razie są to najszybsze jednostki w naszej flocie.
Prezentowane
jednostki będą stacjonować w bazach bałtyckich, natomiast starsze ścigacze typu
Wilk (MGB-3 1924) oraz Chart (MTB-5 1924) zostają detaszowane
na PPTR.
