Ścigacz torpedowy typu Chart 1924-1925 (8 szt.) i ścigacz artyleryjski typu Wilk 1924 (2 szt.)

Ścigacz torpedowy typu Chart 1924-1925 (8 szt.) i ścigacz artyleryjski typu Wilk 1924 (2 szt.)

Następny etap rozwojowy ścigaczy. Ponieważ obydwa typy ścigaczy zbudowane są na takim samym kadłubie i wyposażone w taką samą jednostkę napędową, prezentuje je razem w jednym poście.

Aby uzyskać raporty musiałem trochę „poszachraić”, ale nie było innego sposobu. Springsharp bierze pod uwagę wyłącznie pływanie wypornościowe i takie wynalazki, jak planujące ścigacze wg niego nie istnieją. Słusznie za to program wytyka nędzną dzielność morską, ale dla jednostek tych klas to normalne.

Nie będę rozpisywał się na temat uzbrojenia, osiągów itp., wszystko można wyczytać w raportach i zobaczyć na rysunkach.

Okręty będą działać w dywizjonach w składzie 4 ścigacze torpedowe + 1 artyleryjski. Na ścigaczu artyleryjskim będzie zaokrętowany d-ca dywizjonu. Oprócz roli prowadzącego dywizjon, do zadań ścigacza artyleryjskiego należeć będzie wsparcie ogniowe ścigaczy torpedowych zarówno w ataku, jak i obronie.

Na początek ścigacz torpedowy.
