Re: Anson and Tirpitz

Hello Dave, What I think needs to be underlined is that full loads for battleships varied very much, according to their designs. If we compare Tirpitz with Richelieu, at full load, we get the impression that Tirpitz was a much larger battleship. In fact, they were about the same size (about 250m lo...

Re: KGV + PoW

Bismarck was 224.55m WL length and 43283 tons for 179 tons/meter so KGV seems svelte in comparison. Bismarck was 242m WL length, not 224. When Bismarck displaced 43283 metric tons, KGV displaced over 39500 metric tons. You are using (probably) May 1941 data for Bismarck weight and Oct 1940 data for...

Re: KGV + PoW

Hi Alec, I think that the welding technique used for Bismarck and the absence of structural decks when armored ones were present (the armored decks in Bismarck play also a structural role, not sure about KGV, previous British ships did not used this ) helped Bismarck to be not so heavy for her size...

Re: KGV + PoW

Bismarck's standard displacement grew over time, which was a natural process for all WW2 battleships. In March of 1941 the KM estimated Bismarck's standard displacement as 43150 tonnes or 42470 tons. http://www.kbismarck.com/bismarck-richelieu-vergleich.html Yes, I think this is where we disagreed ...

Re: KGV + PoW

Standard displacement has only one definition and was defined by the naval limitation treaties. And still here we are, with 3 different displacements for Bismarck, 41663, 41881, 42629 tons at standard displacement. As far as armor goes, you need to take into account that KGV's belt protected about ...

Re: KGV + PoW

So I do have a somewhat odd question. Could Bismarck be considered lightly armed for her size? 8x15" seems kind of few especially when we consider what say the RM or the USN were packing which was 9x15/16" respectively while being nearly 100ft shorter (Veneto class, SD class, North Carolina class, ...

Re: Bismarck firing procedures at DS

:lol: :lol: :lol: Rowell declaration at board: 42. In your Captain's report of the action it is stated that "Hood" opened fire at 0552 1/2 and that she blew up at 0600. As you probably assisted in making this report, can you tell us if these times are accurate or not? They were complied on the foll...

Re: Anson and Tirpitz

Gentlemen, I have taken a post from Alecsandros in the Bismark & Tirpitz myth and planted it here (hope you don't mind Alecsandros). 'KGV displaced 37500 tons standard and Bismarck 41700 tons standard. Yes, Bismarck was heavier , but not in the proportion usually considered. Tirpitz weighed 44200 t...

Re: KGV + PoW

The KGV class displacement data was carefully recorded by the Admiralty whereas Bismarck's data has not been so conveniently available. Hence the revised figures over the years. I am fully confident in Mr Rico's figures and I'm sure that most board members accept them as correct. But are you confid...

Re: KGV + PoW

The data on Kbismarck.com for Bismarck's weight has been arrived at after years of study by Mr Rico and has to be given a lot more consideration than earlier figures by Koop and G&D. The same consideration needs to be applied to KGV displacement, and having the same authors publishing the two books...

Re: Bismarck firing procedures at DS

Hello, Hmm yes, there is a difference, what I'm trying to say is that perhaps to explain the odd number of shells fired, Bismarck's guns were having problems at some point during the battle thus leading to that number. Thanks for the links, so we can summarize the following as: Rowell: 3-4 salvos b...

Re: KGV + PoW

Tirpitz also gained weight due to additions - radars, AAA guns, ammo, men, etc. see here: https://www.bismarck-class.dk/technicallayout/bismarck_vs_tirpitz/bismarck_vs_tirpitz.html a more detailed description of weights of Bismarck. see empty ship = 39931 tons; see type displacement = 42343 tons*. ...
