There are two more things. Liquid cooling better preservates the engine, as que cylinder is cooled more even than a radial engine cylinder, which has hot spots that are difficult to deal with. The radial has an additional requirement in the machining of the cooling fins, which are machined from a so...

Sorry, the book I mentioned above is "The U-Boat: The Evolution and Technical History of German Submarines" (Rossler), originally a German book translated to English. The author describes in detail the process of Type XXI assembly, and mentions the system was adopted for Type XXI as part o...

Don´t think so, the prefabrication started with the Type XXI, not before.

May be, in this case two circles are side by side near the deck and one near the bottom, what gives the hull a rough triangle section, the sides composed by the sweeps of the circles. I am reminded of scanning the image...

That´s right Robert, an object striking the water at 500 m/s is almost the same as striking earth or rock, people falling to the water from 50 m height can die.

Yes, they explode, there are many instances of splinter damage from a nearby impact.

Hi Frost. You can do the work spectacularly, setting of a charge in one of the shell rooms (bow or stern), and blow the ship like HMS Barham did in the Med, or open sea cocks (water entrances located in the bottom) and let her sink slowly.

Bearing in mind that just 10 countries built (or have built by others) Dreadnought warships, 1.3 billions seems a little low.

Hi Robert. You are right, we are not so much behind, but anyway both countries have more pressing needs than raising the ship. A scandal would erupt if much money is wasted in the salvage operation.

Yes, some info may need to be obtained from other sources. I can not think of any single source that has all you want. Moreover, the armouring scheme is also important, a plate thickness figure will not do in some cases.

You need to buy Jane´s Warships of WWII. It is a reprint of the contemporary Janes´, it contains some mistakes due to the secrecy of the belligerants, but it has sketches with the armour and firing arcs of most warships of the period.

Hi Noel, I did receive your mail last year but I was really in a hurry and couldn´t spare much time. I am glad you have been to Argentina, next time do not hesitate in contacting me so we can meet. Regarding the Spee, I doubt it will ever be raised, or will ever be some major part recovered. Argenti...

According to "The German U-boat" his designs consisted of a three circle section, I will try to scan one image of that type of hull.

The Bismarck shafts are angled to the ship centreline, I don´t remember the exact angle now.

Hi guys, thanks to all for the updates on this post and to Noel for bringing them to my attention (some months ago!).

I am still curious about Herr Nilson scanning, is there more info on this?
