10 października prezentowałem mały pancernik wieżowy,
uzbrojony w 4 gładkolufowe działa 170-funtowe: http://springsharp.blogspot.com/2013/10/flota-polska-w-xix-w-pancernik-wiezowy.html
Na przełomie lat 70-tych i 80-tych jest to już jednostka przestarzała, nie
odpowiadająca wymogom współczesnego pola walki. Zwłaszcza archaiczne jest
uzbrojenie w działa gładkolufowe, ale też i pancerz nie pozwala mierzyć się z
nowoczesnymi pancernikami. Jedyne do czego jednostka by się nadała, to rola
okrętu obrony wybrzeża, a i to jedynie po głębokiej modernizacji. W jej ramach zlikwidowałem
ożaglowanie, które dla okrętu obrony wybrzeża było by tylko zbędnym balastem. Do
tego wymianie uległy maszyny oraz pancerz z żelaznego na stalowy. Ale
najważniejszą zmianą jest uzbrojenie, które teraz tworzą dwa odtylcowe działa
gwintowane kal. 229 mm,
a oprócz tego kilka lekkich działek szybkostrzelnych, do zwalczania
torpedowców. Poniżej prezentuję dwa rysunki okrętu po modernizacji: ze
złożonymi i podniesionymi nadburciami.

Prezentuje się bardzo ciekawie. Ale pierwszy raz spotykam się z opuszczanymi i podnoszonymi nadburciami. Czy można prosić o jakiś link do "rzeczywistego" przykładu, bo rozumiem, że takie gdzieś w tej epoce pływały?
OdpowiedzUsuńAleksander
Wczesne pancerniki wieżowe tak miały, już HMS Royal Sovereign. Chodzi o umieszczenie wież jak najniżej.
OdpowiedzUsuńZgadza się, stosowano taki zabieg, by obniżyćpołożenie wież, a jednocześnie zapewnić odpowiednią wysokośc burty dla wymaganej dzielności morskiej. Przykłądami są wspomniany Royal Sovereign: http://en.wikipedia.org/wiki/HMS_Royal_Sovereign_%281857%29
OdpowiedzUsuńPrince Albert: http://en.wikipedia.org/wiki/HMS_Prince_Albert_%281864%29
Scorpion i Wivern: http://en.wikipedia.org/wiki/HMS_Scorpion_%281863%29
okręcik wygląda dośc cudacznie, ale w sumie to niezła modernizacja starego grata - jestem na tak!
OdpowiedzUsuńPiękny przykład rewitalizacji pływającego zabytku!
