Duży rosyjski krążownik pancernopokładowy



Witam po dłuższej przerwie, spowodowanej zarówno pewnym brakiem czasu, jak  i  - pewnie nawet w większym stopniu – zimowym dołkiem:( mam jednak nadzieję na w miarę regularne w przyszłości zamieszczanie nowych postów na blogu:)
Przechodząc natomiast do meritum – prezentuję dziś krążownik pancerno pokładowy mojego pomysłu dla floty rosyjskiej. Na przełomie wieków Rosja za głównego potencjalnego przeciwnika na morzu upatrywała w Royal Navy. Na wypadek wojny z Wielką Brytanią, pod koniec XIX w.  zbudowano kilka dużych krążowników pancernych przeznaczonych do działań na liniach komunikacyjnych wroga. Było to jednostki o wyporności ponad 10.000 ton, mające za główne uzbrojenie 4 działa 203 mm i prędkość nie przekraczającą 20 w., co mnie osobiście wydaje się wartością ciut za małą do wypełniania zadań korsarskich, za to posiadające opancerzenie burtowe, niekonieczne akurat do tego rodzaju zadań. Moją propozycją alternatywną jest poniższy okręt – o zbliżonych wymiarach, ale bez pancerza burtowego, za to szybszy – taki ekstremalny krążownik pancerno pokładowy (choć może w sumie nie jest taki ekstremalny bo brytyjskie Terrible i Powerful były jeszcze większe).

  1. I was checking your blog quite everyday and finally you're back.
    Great ship as usual!

    1. That’s true, I finally returned after a long absence, in the future I intend to write regularly on my blog. I’m glad that You like my ship:). I also hope you are not angry that I took parts from Your picture of Abdul-Kadir. Of course, there is nothing against the use of my drawings:)
      I seen also Your pictures of another turkish battleships, they are really cool;) Especially Abdulmecid I – it is a little similar to german pre-dreadnoughts, which are one of the most beautiful ship in the history.

  2. There's absolutly nothing wrong with using parts of my drawing or even my entire drawing (if you want to up date your post of the abdul-kadir for exemple).
    i would be very wrong to refuse that, as lot (even most) of my drawing are kitbashing........
    The only thing i ask is to comply with the rules of shipbucket and give credit if, like in the SB form, the name of the author is shown. But as there's no author mentioned on your drawings...........

    Glad to see you back

  3. OK, in the future I will mention nickname author of drawing which I used. Sometimes it may be a few people, because I often use a number of drawings that I have in my collection.

  4. It's not mandatory. what i meant was that as you don't mention the author of the drawing (you got your own form), to me you don't have to mention anyone.

  17. This software helps you customize nutrition dependant on your real age, weight, height, and metabolism.
    Yes we would like muscle, but in the right way, and gaining lean muscle without fat is
    the key to doing this. It will never feature large degrees of filler information, or even lengthy explanations.

  18. Setting up a blog is not all that complicated and it is perfectly fine to use one of
    the free blogging platforms such as Blogger,
    Wordpress, or many more. If they were making good money, like most of them claim,
    an uninterested client or two wouldn't "hurt" them as much as they are showing. I usually come out and build 2-3 niche sites every week to target profitable micro niches.
