Very true the H class was a larger heavier design. All I am saying is to maintain the designs specs related to draft which is of course linked to total displacement, the main belt had to be reduced. Yes the overall 'spaced' armour arrangement was increased over the Bismarck. Reducing the thickness o...

In weight terms alone the extra weight of the horizontal armour was minimal. If you look at overall balance ( stability) of the design with the relatively large increase in artillery weight together with draft limitations; The reduction in belt weight has a majority effect. I will admit that I was a...

As I said all I was doing was theorizing what I think would be required to investigate, with minimal distruption of the turrets, to further any future battle analysis. The turrets being smaller than the hull it might be possible to scan the surface ( something I did not clarify earlier, surface scan...

The question I have is I had read that there is or was a belief that the design of any warship is in part based on her choice of engine and swapping engine design after what seems be a firm design, is not a easy change to implement. The fact that the design had been finalized at least the engine spa...

I think we should not forget the compromise between armour and total cannon weight. Added to that is the limitation on design related to strategic concerns various nations had to compile. Case in point is America's use of the Panama canal, which limits the beam to approximately 107 to 110 feet. Any ...

There is more evidence out there that exchanges of information bertween Japan and Germany took place throughout the war. Apparently such an exchange of information during 1942 is the source of the true specifications of the Yamato was first confirmed.

My last comment was more to reflect the impossible nature of non_intrusive investigations of the turrets in their current position would be with CURRENT technology. I am not that much caught up in fictionalized stories like CSI etc.There is enough confusion between what is one author's opinion and w...

After some further reviewing what information I have on intended use of major surface units, I think I may have stumbled across an interesting bit of information that may be of interest. My way of thinking is that it is purely coincidence that most major warships make good commerce raiders and it ca...

Concur completely. Non intrusive penetration by small robotic units only. Considering the positions the main turrets are located, physical access is impossible. Maybe development of something akin to ground penetrating radar could be developed to gain a non intrusive 'picture' / outline will be our ...

It has been known for some time that any dead animal whose body makes it to the bottom of very deep oceans is quickly consumed by various creatures that scavenge on the bottom. Only very large animal like whales leave any observable remains and what is.left of other smaller bodies soon dissolves in ...

Do not know if this has already been asked and answered already so here goes. I seen the statement on a number of occasions where the large size of the engine spaces was because the Bismarck's design was initially due to the idea of an electric drive plant was going to be used. Suggestions that eith...

In bring up the Yamato the discussion needs a bit of historical understanding for that design. Although the Yamato was not treaty restricted in any way, it is wrong to think that there was no strategic restrictions at all. Restrictions of draft was a major factor due topographical consideration in m...

From everything I read on it and the photos of the steering motors indicate that once the rudder compartment was flooded the motors that seem ( at least going on the photos ) were not water proof and would have been rendered inoperable under the stated conditions. If memory serves me right manual co...

Further research suggests a. DC limit of 10Mw per motor. So to achieve the approximate 40,000 shp per shaft would indicate multiple electric motors per shaft. Also as AC power was more desirable for RPC gunnery control units AC power would make more sense.

Quite correct. My source material mentioned three occasions. First during during trials if memory serves me correctly, second at Jutland and the third in WW2. Your right about a journal article, I already started a draft for my website, along the lines that it would have not mattered one iota how ma...
