Re: Battleship for Freedonia

I agree that bombs seem a serious threat to the German armour scheme. After the attack on Scharnhorst, the H39 design was revised to resist bombs resulting in the H41 paper design. This strengthened the scarp from 150 mm to 175 mm and replaced the 120 mm main deck by one of 200 mm. It was also propo...

Re: Battleship for Freedonia

The bomb damages inflicted on Tirpitz showed that it was not particularly vulnerable to bombs compared to contemporary designs. Yes and no. The combination of the 50mm weather deck plus two decks worth of spacing to reach the panzerdeck makes penetration to the vitals unlikely. OTOH, given how low ...

Re: Battleship for Freedonia

Let us try to choose the best armament for our battleship. I am going to agree with Dave on the secondary armament. The only available alternatives are USN's 5"/38 or the RN's 5.25". We will select the 5.25" as it will be better for dealing with destroyers or aircraft dropping Fritz-X bombs. However...

Re: Battleship for Freedonia

Bombs represent an intractable problem because they can strike at or near the normal. Perhaps Freedonia's fortune tellers will discover that even the Musashi's horizontal protection will fail against bombs. The bomb damages inflicted on Tirpitz showed that it was not particularly vulnerable to bomb...

Re: Battleship for Freedonia

I feel that I must pause on watching football to give a few more details of Freedonia's position. As most of you know, Freedonia is positioned in the Indian Ocean and is descended from the kingdom of Queen Ranavalona https://en.wikipedia.org/wiki/Ranavalona_I, who was instrumental in creating a navy...

Re: Hitting the Gun Barrel

It happened to South Dakota, possibly more than once. At Santa Cruz https://www.navsource.org/archives/01/57a.htm has: “The ship received a direct hit from a 500-pound bomb on top of Main Battery Turret # 1. It did not penetrate but deformed two of the three 16-Inch barrels of #2 turret.” At the Sec...

Battleship for Freedonia

It is around 1936 and I have been appointed as Navy Minister by Freedonia. We are planning to build a battleship or class of battleships. As Freedonia has reasonably good relations with all the World's major naval powers, we are able to use technology from any country. We even have a few engineers w...

Convergence of unbuilt battleships

The H39 Battleships would have had a main armoured deck, MAD, of 120 mm over the magazines under an 80 mm armoured weather deck. They would have had a 100 mm MAD over the machinery under a 50 mm weather deck. Thus they are a natural evolution from Bismarck, following a similar philosophy. On the oth...

The Structural role of Main Armour Decks

Battleships were constructed as a girder of the keel, normally a double bottom, and the main armour deck (MAD). However, different navies constructed the MAD differently. The USN made their MADs as laminates. Thus, Iowa has a 4.75" upper layer on a 1.25" lower layer of homogeneous armour. Friedman's...

The range at which actions were fought

The designers of the last generation of battleships started with various expectations on the range at which their designs would exchange shells with other battleships, which was the reason why battleships were built rather than cruiser killers such as Scharnhorst or Alaska. I decided to survey what ...

Re: Political correctness gone mad?

Some way back in the thread I mentioned that politicians do not always act exactly as if they regarded climate change as a priority. Here are some good but now old quotations that I found at http://www.inference.org.uk/sustainable/book/tex/sewtha.pdf on page 222 from Tony Blair. Speaking on climate ...

...snip... Regarding sea level rise, we have not seen an acceleration in rate of sea level rise. It is still rising the same 1-3 mm per year that it has been for centuries. Yes, that is millimeters, not centimeters, and certainly not meters. The 5 metre figure was obviously taken from someone's mod...

Re: Political correctness gone mad?

I find the posts of the opponents of global warming very puzzling because, while it is sometimes clear what they do not believe, it is not at all obvious what they do believe. For example, does RF accept the evidence from satellite measurements of the Earth's surface temperature, the average troposp...

I remain convinced that the observed warming over the last forty years (the period for which we have good satellite data) is real. Natural variation is the more likely explanation. The established range of natural variation overwhelms any warming over that period. ...snip ... I was arguing that the...
