Zgodnie z
zapowiedzią, dziś projekty japońskie z programu 8+8 (nazwa programu
miała wyrażać siłę japońskiej floty: 8 pancerników i 8 krążowników
liniowych. Zbudowane okręty (Nagato i Mutsu) sobie daruję. Zatem, na
początek pancerniki typu Tosa (drugi: Kaga) i krążowniki liniowe typu
Amagi (pozostałe: Akagi, Atago, Takao). Mamy tu do czynienia z okrętami
dość szybkimi (26-30 w.), ale raczej słabo opancerzonymi (pancerniki pb
280 - to mniej niż na poprzednich typach japońskich pancerników, a
przecież te okręty miały walczyć ewentualnie z nowymi okrętami
amerykańskimi (działa 406 mm) czy brytyjskimi (działa 457 mm). A
należało się liczyć z faktem że w przyszłości kaliber artylerii
pancerników jeszcze wzrośnie, być może osiągając nawet 20 cali (508 mm)
co wydaje się być granicą rozsądku.. w tym kontekście tak słabe
opancerzenie nie wydaje się być rozsądnym wyjściem. Ale to i tak lepiej
niż 7 cali pancerza burtowego na planowanych amerykańskich Lexingtonach
:-D - z tymi strach było podchodzić do czegokolwiek powyżej "zwykłego"
krążownika, a najlepiej to od raqzu zwiewać jak tylko się pojawi dym na
horyzoncie:-D
No, ale miało być o Japończykach.. Oto raporty ze springsharpa:
