Kilka okrętów dla urugwajskiej MW - 06.07.2012

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:-)
