W
nawiązaniu do wczorajszego postu z wenezuelskim pancernikiem obrony
wybrzeża - dziś przedstawiam kilka projektów mniejszych okrętów dla
ichniejszej floty. Chronologicznie są to: torpedowiec z 1891 r.,
kanonierka z 1895 r., krążownik torpedowy (kanonierka, jak kto woli) z
1896 r. i niszczyciel z 1901 r. W sumie - całkiem zgrabna mała flota
obrony wybrzeża:-)
