Hi Billy, Interesting! I was familiar with the canted rudder arrangement in use with German S-boats, but never contemplated whether this method would prove practicable with capital ships. My gut instinct suggests probably not - there after all being HUGE difference between an S-boat and a Bismarck, ...

I see we have brewing what appears to be yet another exercise in cynical Italian rhetorical gymnastics. Rather than actually PUBLISHING something ...anything... as they have endlessly pronounced as their intention for at least a decade , our two Italian gentlemen have demonstrated an apparent prefer...

I suggest that we dispense with debates over paternity and focus on the analysis offered in this new book.

I am now close to the end of this book, having started on June 25. The authors remark that there was difficulty in damaging Bismarck at very close range because of the sea state. Waves were six to eight meters high. This would have meant that under a range of 5000 m, the last 100+ m of the shell tr...

OK Marcelo, Found it – CB1516(A) REPORTS ON INTERNED GERMAN VESSELS Part 1 – Constructive Details and Machinery "Main Machinery – These ships appear to be very well built, and from the manner in which the ships are subdivided they would be very difficult to completely put out of action. They are all...

Hi Byron. So there was a HP turbine coupled to a LP one which in turn coupled to the shaft? All in the same line? Regards Hi Marcelo, I cannot confirm that detail without more homework. The four shaft German BCs had two sets of machinery, with the high pressure turbines running the inner shafts and...

Guys, how were the turbines arranged in WWI three shaft German´s battleships? Hi Marcelo, Typically, three sets of turbines abreast, with each separated from its neighbor(s) by a longitudinal bulkhead. Additionally, each turbine set had its respective high and low pressure turbines in separate fore...

Dear pasoleati, Wow ..... a great deal of fire and passion on your part. I'm just wondering why you are directing such ire toward Bill Jurens. Bill did not write the rules of the academic research game; all he has done is describe how they currently work. Without academic credentials connecting you ...

See DK Brown's "Design and Construction of British Warships" regarding fuel consumption and endurance. There could be dramatic differences between trials values and actual wartime service values.

Howe_endurance1.jpg What book is this from? Regards British Battleships of World War two , by Raven and Roberts. - - - Hi Thorsten, [ 1 ] Were any displacement data provided in connection with the above-mentioned Howe endurance figures? [ 2 ] If one already possessed Friedman's book on British BBs ...

Thanks dunmunro.

According to Howse the first 5 operational type 284s fitted to Battleships were Hood, KGV, PoW, QE and probably Nelson.

Is it possible to ascertain with any confidence whether those ships were likely the first five ships on any class so fitted?

If we include ranges from light cruisers, whose DCT mounted radar antennae were ~33% lower in height than a battleship's, then the ranges make sense, but they are not representative of actual ranges obtained by battleships in trials or in combat. A couple of thoughts - > CB4112(4) mentions that its...

Daft question....
Do atmospherics make a difference to radar performance?

Yes. Meteorological conditions and other anomalies (such as atmospheric ducting), even sea state to a degree, can influence radar performance.
