Dziś włoska mini-Dunkerque :) Czyli okręt w ogólnym zarysie i kształcie zainspirowany tym francuskim pancernikiem, ale w mniejszej skali. Okręt jest uzbrojony w działa 10-calowe nowego typu, wywodzące się z dział model 1908 w jakie wyposażano włoskie krążowniki pancerne (Pisa, San Giorgio). Z typowej artylerii średniej kalibru rzędu 6 cali zrezygnowano, na rzecz baterii dział kal. 100 mm, które od biedy mogą służyć do zwalczania celów latających jak i niedużych pływających (przeciw tym większym konieczne będzie użycie artylerii głównej). Okręt jest przyzwoicie opancerzony (pb 180, pag 180, pp75), i osiąga zadowalające 33 węzły. Można go więc uznać za rodzaj niszczyciela krążowników waszyngtońskich, od większości których wprawdzie nie jest nominalnie szybszy, ale jako jednostka większa, powinien być szybszy realnie (nie powinien tracić z prędkości tyle co one przy gorszych warunkach). Pomysłodawcą okrętu jest kol. ŁK, któremu mam nadzieję taka realizacja się spodoba :)
