Dave: I am aware of the Italian approach -- although it is indirect knowledge through British attempts to imitate the Italian results. The British appear to have been somewhat under-whelmed when they conducted there own tests of this Italian philosophy using super caliber 14” APC. But as I have alre...

An additional comment on spaced armor... It wasnt so much to increase effective thickness or limit velocity as seen by an attacking projectile as much as a means of contain behind armor effects of penetrating shots. Spaced arrays were considered a means of containing blast, fragmentation, and high v...

Dave: I think in reality a spaced 3” armor array would resist like a single plate thickness of perhaps 2.8” or 2.7” -- particularly against 16” APC. You will find by studying the subject of spaced armor that it represents a mixed bag of potential results. On the other hand spaced arrays ‘can’ be eff...

So than the initial format of your equation should be: [(t/d x 1.34)^0.5] x V for FHA; or [(t/d x 1.25)^0.5] x V for HHA Going back to your first example of 16” AP striking 3” of FHA: Is the 3” FHA spaced plate supposed to be the total thickness of the spaced armor array? In other words is this two ...

THE EAGLE HAS LANDED -- Beer Stein Trials Report
OK -- I received my Bismarck Beer Stein today. It has a nice Bismarck Insignia on one side, and a great action shot of a Swordfish torpedo attack on the opposite side. I was disappointed that there wasn’t a picture of a naked lady on the inside bottom of the stein. BISMARK STEIN TRIALS: I wasted no ...

It sounds like a challenge finding enough info on projectiles from this period. I'd be interested in hearing more about the methodolgy though, it's obviously more modern than anything than I've used. But do the results outweigh the extra effort involved in finding orders of magnitude more data? Mik...

Hi Ulrich: I think you’re onto something with that last post. It would certainly explain why I can’t seem to find this terminology in DPG testing reports and memoranda. A useful term if I understand it correctly -- particularly for confined areas. It's unclear how a particular projectile --Cardonald...

Re: Terminology
Terminology is specific to time and place. I don't think you'd find any such terminology in a British Admiralty document of WW2 or earlier, I haven't seen enough USN ones to know what they were doing. My interpretation is that although they would recognise the concepts these terms represent a conve...

Thanks for posting the URL Ulrich -- you are an amazing search engine . As you know I am in the process of a bit of research on WWI AP projectiles. To that end I am interested in information that is traceable to specific source material. Over the years I have become a little skeptical of unreference...

Not exactly scaled down, they're slightly different lengths (3.2 cals vs. 3.4). Sounds as though you want to feed it to mcdrag? I have played with it, but no. I develop specific Cd curves based upon projectile shape and pressure distribution around the projectile as various speeds. It's a bit more ...

Holing Limit?
The Cardonald shell strikes me as something of an achievement. In practical terms, its superiority was in its ability to handle extreme obliquities, almost matching US shells in that regard, but retaining the larger burster typical of British shells. If you look at the FACEHARD calculations, you wo...
