Kolejne okręciki dla polskiej floty:) Pierwszy z nich to
pływająca bateria uzbrojona w ciężkie, 60-funtowe działa gładkolufowe, mająca
służyć do obrony bazy w Lipawie (to będzie nasza główna, a przez dłuższy chyba
czas jedyna baza morska). Nie ukrywam, że okręt jest inspirowany nieco
podobnymi jednostkami brytyjskimi i francuskimi z wojny krymskiej, które wówczas
dowiodły swojej skuteczności. Różnica w stosunku do nich polega na tym, że
okręt nie posiada opancerzenia, bowiem nie ma walczyć z wrogimi fortami tylko
okrętami, w domyśle – również nieopancerzonymi.
Drugi okręt, to zmodyfikowana kanonierka, również niosąca
najcięższe wówczas we flocie działo 60-funtowe. Nazwy okrętów w typie utrzymane
są nadal w konwencji mitologicznej..
