"Monokalibrowy" krążownik pancerny



Po krótkiej przerwie wracamy do krążowników:-D  Tym razem krążownik pancerny z jednolitą artylerią 152mm – czyli taki nasz odpowiednik Monmoutha. Do bitwy sił głównych raczej się nie nada (przez brak jakiejkolwiek artylerii ciężkiej) ale siły lekkie może mocno poszarpać, poza tym powinien się nadać do prowadzenia wojny krążowniczej, gdzie brak dużych dział specjalnie nie powinien przeszkadzać – stąd dobra dzielność morska (wysoka burta!) i znaczący zasięg, istotnie większy niż poprzednich typów naszych krążowników pancernych.
Pomysłodawcą jednostki i autorem rysunku, który nieco zmodyfikowałem, jest kolega JKS;)

Monitor rzeczny na Jangcy

Czas trochę odpocząć od tych krążowników;) (zwłaszcza że jeszcze kilka projektów nas czeka w najbliższym czasie). Dziś prezentuję parę rzecznych monitorów, przeznaczonych do służby na Jangcy.

Krążownik pancerny typu Garibaldi



Oto zapowiadany krążownik pancerny typu Garibaldi:) jest to swego rodzaju „zakup interwencyjny”, by doraźnie podratować nasze siły krążownicze, które około przełomu wieków nie prezentują się zbyt okazale. U schyłku XIX w. do nowoczesnych krążowników pancernych należą tylko 2 jednostki typu Piast, pozostałe 3 okręty to stare jednostki przebudowane z pancerników pochodzących jeszcze z lat 60-tych i 70-tych XIX w. i kwalifikują się do wycofania, jak tylko pozyskamy ich następców – a tymi są niniejszy okręt oraz prezentowany niedawno, pozyskany równolegle, krążownik pancerny typu Bajan.

Nowe torpedowce



Dziś dawno zapowiadany okręt, czyli duży torpedowiec. Może najpierwszy rzut oka nie wygląda na taki, ale w istocie jest to okręt w typie niewielkiego niszczyciela (oczywiście, według standardów z końca XIX w.) Dla porównania, współczesne mu rosyjskie niszczyciele typu Pyłkij (wodowane w latach 1898-1901) były niewiele większe, bo wypierały od 220 do 240 ton.

Krążownik pancerny typu Bajan



Postanowiłem wcielić do naszej floty krążownik pancerny typu Bajan – niemal bliźniaka okrętu zbudowanego przez stocznię francuską dla Rosji. Ponoć Francuzi oferowali Rosjanom zbudowanie drugiej jednostki tego typu w 6 miesięcy po prototypie i w promocyjnej cenie, z czego ci ostatni nie skorzystali. Promocja nie była jakaś oszałamiająca, bowiem wynosiła 200.000 franków przy cenie pierwszej jednostki wynoszącej 16.400.000 franków. Ponieważ jednak bardzo lubię akurat ten typ (sam nie wiem czemu;)) to pomyślałem, że moglibyśmy skorzystać z oferty jaką przedstawiono flocie rosyjskiej. We flocie polskiej krążownik nosi nazwę Zawisza Czarny, bowiem stary taranowiec o tej nazwie wycofałem już w 1896 r.
Mając świadomość pewnych wad, jakie okręt ten niewątpliwie posiada, trzeba będzie się zastanowić co dalej w kwestii krążowników pancernych? Wstępnie myślałem o czymś na kształt jednostek japońskich (10.000 ton, 4x203, niezłe opancerzenie), które to jednostki mogły by współdziałać z flotą liniową na Bałtyku, stanowiąc jej szybkie skrzydło - w tym przypadku mielibyśmy do czynienia z funkcjonalnymi protoplastami krążowników liniowych, podobnie jak to było z krążownikami japońskimi. A może bardziej przydadzą się okręty ukierunkowane na działania na liniach komunikacyjnych, cechujące się dużym zasięgiem kosztem opancerzenia. Takie jednostki przydały by się najbardziej na wypadek wojny z Anglią, która na przełomie XIX i XX w. była dla nas jako sojusznika Rosji wciąż jeszcze realna. Chodzą mi po głowie też nadzwyczaj udane, a przy tym nieduże (a więc i niedrogie) włoskie krążowniki pancerne typu Garibaldi, które mają to do siebie, że wystepowały w każdym możliwym wariancie uzbrojania: 1x254 i 2x203, 4x203, 2x254 – do wyboru, do koloru;) Co o tym sądzicie? Zapraszam do „burzy mózgów”;-)

Nowa kanonierka pancerna

Oto nowy okręt, kanonierka pancerna wzorowana na rosyjskiej Chrabryj, a jednocześnie rozwinięcie okrętu Hydra z 1888 r.: http://springsharp.blogspot.com/2014/03/kanonierka-pancerna.html
Wielkością, siłą ognia i opancerzeniem przewyższa nie tylko wszystkie dotychczasowe kanonierki, ale i wiele z naszych małych krążowników (mających po 1200-1500 ton), które z tego powodu chyba trzeba będzie rychło przeklasyfikować na kanonierki...

Nowe zaopatrzeniowce



Kolejna jednostka dla naszej floty:) W tym przypadku jest to zaopatrzeniowiec z dodatkowa możliwością pełnienia funkcji krążownika pomocniczego. Zadaniem okrętu jest zaopatrywanie zespołów okrętów na odległych akwenach w amunicję, żywność i inne materiały, za wyjątkiem paliwa, bo od tego będzie węglowiec (węglowce?). Zadanie drugorzędne to transport materiałów wojennych przede wszystkim do kolonii. Typ liczy sobie trzy jednostki: Nowa Kurlandia, Madagaskar i Hajnan. Nazwy oczywiście pochodzą od naszych kolonii, przy czym Nowa Kurlandia to po prostu Liberia (przecież kolonia nie może się tak nazywać, stąd wymyśliłem własną nazwę..). W związku z wprowadzeniem aż trzech nowych transportowców wycofany zostaje ze służby stary transportowiec Kurlandia z 1874 r.
Autorem rysunku i pomysłodawcą jednostki jest JKS:)
