Żaglowiec szkolny



Postanowiłem powiększyć naszą flotę o żaglowiec szkolny, który przyda się do podstawowego szkolenia kadetów naszej floty. Rysunek zamieszczam dzięki uprzejmości kolegi  JKS, który mi go podesłał z prawem do publikacji na blogu. Ja rysunek trochę zmieniłem, tak by dopasować do stylu w jakim sam rysuję (zmiany dotyczyły omasztowania, bandery, malowania kadłuba). Mam nadzieję że się spodoba, choć zdaję sobie sprawę że oryginalna wersja pod żaglami wyglądała zapewne bardziej okazale...

Nowa kanonierka



Dzisiaj kanonierka w typie mini-pancernika:) (przynajmniej jeśli chodzi o sylwetkę) Rysunek tym razem nie jest mój, a pochodzi z forum shipbucket.com, i został nieznacznie tylko przeze mnie skorygowany. Okręcik ten spodobał mi się na tyle, że postanowiłem go włączyć w skład floty. Mam nadzieję że i Wam przypadnie do gustu:)
ps. skoro okręt się spodobał, to nie będzie jedynakiem:) Aktualnie typ liczy 5 jednostek, a ich listę - tradycyjnie - zamieszczam na końcu posta, za raportem ze Springsharpa.

Modernizacja krążowników typu Admirał Lesowski



W latach 90-tych nasze największe krążowniki pancernopokładowe wymagają już pewnego odświeżenia. Są jeszcze na tyle nowe, że zabieg taki ma pewien sens, choć oczywiście nie długofalowy – przewiduję, że w nowej postaci okręty posłużą do ok. połowy pierwszej dekady XX w.  W ramach modernizacji zlikwidowałem ożaglowanie, wymieniłem artylerię na szybkostrzelną (działa 152 mm model 1891), no i zmodernizowałem napęd, dzięki czemu jednostki są teraz w stanie „wyciągnąć” 18,5 w. Cudów nie ma, ale i tak okręty wydają się być bardziej użyteczne niż w poprzedniej wersji. Niemniej nad krążownikiem pancerno pokładowym z prawdziwego zdarzenia też trzeba będzie pomyśleć , i to raczej szybko..

Nowy okręt podwodny



Kolejną jednostką dla naszej floty jest okręt podwodny – rozinięcie konstrukcji z 1892 r., prezentowanej 14 kwietnia:  http://springsharp.blogspot.com/2014/04/okret-podwodny.html
Zasada działania jest analogiczna – na powierzchni okręt napędza maszyna parowa, a pod wodą – powietrze sprężone uprzednio przez silnik parowy.  Pomimo oczywistych wad takiego rozwiązania i ewidentnej niedoskonałości okrętu jako jednostki bojowej, uważam jego powstanie za konieczny etap na drodze do budowy w przyszłości znaczącej floty podwodnej:)
