Re: Admiral Zheng He (Cheng Ho) treasure ship design

Regarding that other famous boat, try reading Genesis, Chapter 6.
Don´t worry, I don´t believe in that too!!!

Re: Admiral Zheng He (Cheng Ho) treasure ship design

I would have to say that also discredits another famous ship that was measured in cubits...
Which one?

Re: Admiral Zheng He (Cheng Ho) treasure ship design

Sorry Hermill. Until I read the detailed description of the construction technics and see the blueprints of the ships, I am sceptical that such a large ship could be built in those years, as I expressed in my previous posts. Moreover, no ship longer than about 75 m was ever built of wood alone (with...

Re: Submarine + Surface Ship Actions

Combined fleets involving surface ships and subs were discarded already in WWI if I am not wrong.

Re: Battleship Top Ten

The ugliest Battleship of all time:
1. HMS Rodney and HMS Nelson
Very few people would disagree at this... It seems that it is easier to choose the ugliest than the most beautiful.

Brad, it was a static target?

Re: RFC equipped Yamato vs. Iowa

South Dakota in the fall of 1943 scored multiple hits on several salvos at 35,000 yards and ended up scoring a total of 22% for the shoot.
Brad, what was the target?

Re: Battleship Vanguard Armor

I am not an expert but I don´t like the armoured deck seated on TOP of the belt, it is exposed to incoming shells. I would prefer the belt reaching one deck up and the armoured deck being one deck down. But sure there is some good thing in the used scheme, so I will listen to the experts.

Hit probability

I have done my homework. Lets analize what the 8.7% hit probability at 40.000 yards means. I understand that 8.7% is the probability of a single shot hitting Yamato at that distance. Each shot is trial, with a 0.087 success probability and 0.913 failure probability. This is called a "binomial d...

Re: RFC equipped Yamato vs. Iowa

If the engagement starts at 25,000 yards the Iowa needs to make smoke, open range, and pray. This is the key of the thread. Iowa CAN win, nobody argues that. But always needs some type of collaboration from Yamato: keep at long range, don´t fire at all or with little accuracy, keep the damage contr...

Thanks my friend, I have read some parts from the Eugene Slover web. But I think that it lacks some details.

Re: RFC equipped Yamato vs. Iowa

Well, this is getting tricky. Brad, do you have in English something called "binomial distribution of probablity"?

Re: Radar fire control

Thanks Brad for your long explanation. So I understand that the radar only changed the instrument used to measure the range and bearing, the plot still being necesary to determine range rate. Am I right? And a couple of questions: -Bearing was plotted too? -Teoretically you can derive target course ...
