Size of armor plates in side belt and deck

[chuck]

Where can I find information on the actual size of the individual armor plates that made up the side belts and decks of various battleships?

Do you have particular ships in mind?

There is a series of pictures showing one of the early German dreadnoughts being plated, which shows the size of the plates. Also, the Jutland batle damage photos are quite illuminating - though I can't unfortunately claim to have any decent knowledge about the RN side.

Depending on how deep you want to dig company archives might have useful material, too.

My interest only extends as far as pre-WW1 ships, but "Janes" gives armour plating details and "Brassey's" http://www.gwpda.org/naval/bras1913.htm is usually a good source.

I was thinking more of WWII era ships. I wanted to get an idea of the fraction of armor that interior of a solid plate, and the fraction that was weakened by being at mechanical junction between two plates.

Sumrall's Iowa Class book shows detail photos of the fitting of Kentucky's armor belt. It would be easy to determine the sizes from the photos.

Looking at his photos, the vast majority of the junction seems to be tongue and groove, with locating pins about 6" in diameter.
