Re: Yamato and Musashi vs. Missouri and Iowa

I think that it really was a huge 0.4 seconds for the Japanese Type 91 shells (the Type 13 mark 5 fuze is described on page 17 of the USN Technical Mission to Japan Report O-17 http://www.fischer-tropsch.org/primary_documents/gvt_reports/USNAVY/USNTMJ%20Reports/USNTMJ-200E-0240-0319%20Report%200-17...

Re: Rosselsprung 1942 actual combat

Its a simple matter. The effective thickness of the North Carolina class total deck protection is 105mm and the German 38cm can defeat it at ranges exceeding 25km. The deck protection would need to exceed 130mm effective for it to provide protection vs the German 38cm out to 30km. It just doesn't f...

Re: Yamato and Musashi vs. Missouri and Iowa

I think the quoted fuze delay time is off by a decimal place. Should read as .040 seconds, which @450 m/s striking velocity = about 18 meters (60 ft). B I can't vouch for the exact number, but the IJN fuse delay was much longer than anyone else's because their shells were designed to follow a stabl...

Re: Yamato and Musashi vs. Missouri and Iowa

Mr. Guest, I don't think you understand the nature of long range gunnery very well. Since we have stipulated that there is very good visibility, combat will begin at about 40,000 yds or so. The probability of belt armor being hit at that range is pretty much nil. Both ships will be able to penetrate...

That's pretty cool, Antonio. I think that's the first time I've seen anything like that.

Yes, and Krishima took a large number of 16" hits and continued to fight.

Re: Could an H Class battleship survive?

Exactly... She lost some machinery power to dive bombing. It must have been hell on that ship... Yes, the casualties among the AA crews must have been terrible, but they even mentioned an entire DC section being wiped out. That is especially bad on an IJN ship, where only DC specialists help with DC.

Re: Could an H Class battleship survive?

How do you know the first hits would not have caused her to sink? ... I don't. But the messages they transmitted showed the ship was still good to sail. If that was the case or not... we don't know. One thing that enabled her to absorb more damage than one might expect is that there were a large nu...

Re: Could an H Class battleship survive?

Not necessarily preposterous. It took some nineteen hits plus bomb hits to sink the Musashi. With the arrangement of compartmentation and counter flooding ability the KM claim isn't that far fetched and in reality it took eleven torpedoes plus 14 inch shell hits to achieve destruction. See Richard ...

Re: Could an H Class battleship survive?

The Scharnhorst was sunk by at least 11 torpedo hits (these were the large ship launched, not smaller aircraft released torpedoes) and we now know that it was literally ripped apart by them. I believe the Scharnhorst classe were designed such that the KM expected them to float with up to 13 torpedo...

Re: Rosselsprung 1942 actual combat

30* from the normal is 60* angle of fall. Scaled up the middle plate is 7.5" or the effective thickness of the Montana class MAD. A 15" or 16" shell will not have that much deck penetration at 30* angle of fall. It surely must be 30* from the normal and not 60* from the normal, which it would be at...

Re: Rosselsprung 1942 actual combat

Okay, scaled up it looks like it is the USS Montana deck protection design vs 16" at about 40,000 meters range. The 1943 date would certainly indicate this as well. The main problem with yaw not being fully effective is the distance between the upper deck and the MAD is too small for procession to ...

Re: Rosselsprung 1942 actual combat

it would depend on trajectory. some shells may go through weather deck + flat MAD. other shells through weather deck + slope. In Bismarck and Tirpitz, the MAD was a turtle shell design. The slope has little to do with deck protection. It is part of the system including the main armor belt. Shells o...

Re: Rosselsprung 1942 actual combat

... The German system had varying plate declinations, which made it harder for the shell to perforate. Belt: 7-17* next to magazines, slope 60 - 68*, TDS 0*. Decks: 2-3* upper deck forward and aft, 0* MAD, 60-68* slopes. I don't believe the comparison was supposed to have anything to do with the be...
