Allied BBs is the only volume of G§D I'm still lacking what do they write. Imo G&D are the most credible but thats just my opinion.
Sir, good luck with adding that volume to your collection. Just got a copy myself and it was a little pricey to say the least.

You dont know how much comparable the different methods of measuring the effectiveness of TDS were.

The IJN made estimates based upon their research using scale models. These estimates may not necessarily hold true in full scale testing. The model for Bismarck varies considerably from the actual Bismarck SPS in that it has a full height void behind the armoured holding bulkhead, something that Bismarck doesn't have (but KGV does). The KM and the RN, OTOH, tested their designs full scale. I would guess that the IJN made a mistake regarding the Yamato design, and underestimated the brittleness of the armoured bulkhead.

OK, I got an estimate for ADM 116/3594, 128 pages mailed (digital service not available for this) = UK 57.60. = ~$90 Cdn. I'll have to ponder this for a bit. Anyone care to share the cost, in exchange for me sending you a copy?

I would provide some money, but i'm afraid that shipment around the world will cost more than the piece itself.
I will ask my bank for shipment costs.

I could make digital copies for you and send you them, or provide a private link for you to download them.

Yes, Richelieu's TDS is generally considered the best. That's why I find KGV data hard to believe.
It is according to the navweaps and combinedfleet. However Friedman does not speak that well of it and I think (have to check, anyway) that R&R neither. Starting for the overall displacement and beam there are catches.
The two articles on combinedfleet (Guns n Armor, Best Battleship) both rank the SoDak and Iowa classes highly, and ding the KGV class as having the worst, especially because the tops were open for venting.

Interestingly enough, they give Yamato the 2nd highest score, while saying that her design was poor because American torps breached it even though their warheads were below the supposed protection level.

Note how the combined fleet article states that KGV had a "shallow" belt. Not!

The best summary, I think, is in the first document, i.e. ADM116/3594.

If you do decide to chase these down, please let me know what you come up with, as I might like to add a few of the totally missing reports to my own files, and touch up a few of my existing files that are missing various pages. Copying technology has come a long way since 1980 or so...

Thanks for this, Thorsten.

I'm surprised to see that some documents do not seem to be available for copying. I will have to look more carefully in my files to see exactly what I have on this. I store material on the U.S. Navy quite carefully, but am not quite as organized with Royal Navy stuff, so it's scattered a bit, and (in some cases) hasn't been looked at in years.
