Re: Armour Penetration

sounds like you read the same article. those are about the precise words Okun used. while I am perfectly comfortable with scale effects in the traditional sense of how these are defined in terminal ballistics, Okuns point regarding scale effects and face hardened armor was a little unclear to me. mo...

Buyer Beware – Don’t Buy from AviaPress Web Site

Buyer Beware – Don’t Buy from AviaPress Web Site!!! Their website claims to have a lot of very nice looking Russian Publications on Soviet and Russian warships. However, they are notorious for not filling orders. I have ordered magazines or books from them on three different occasions over the last...

I suppose. But there is still an unknown in that he didn't state how much the aft draught increased as a result of the magazine flooding at Dogger Bank. I mean I can back calculate it from the 1500t or the 600t, but to know it was either water volume\weight and using the same ratio of increase in dr...

1500t?

Thanks Serg. Why do you think Seydlitz ended up flooding with 1500tons rather than the 600ton indicated by R. Massie in "Castles of Steel"? I realize the book cover a lot of ground and may include some errors on such vagaries -- but where is the 1500ton thing coming from? What effects migh...

Ok.. Thanks. I actually have it on my bookshelf, but have only read snippets of it. I thought perhaps he had written an article on Dogger Bank for Warship, or Warship International.

Seydlitz Magazine Flooding and Effects on Speed?

I'm in the process of rereading "Castles of Steel" -- I can't help myself as I really enjoy this book. Apparently the aft magazines of Seydlitz were flooded with some 600-tons of sea water during Dogger Bank. What sort of effect might this have on the speed of the ship? 600-tons seems like...

Game -- Distant Guns?

Has anyone played this computer game? Russo-Japanese Naval war in 1904-05. I am curious if it is worth investing in?

Thanks

Very Long Range Shoots

This is sort of silly gee wiz question, and it may have been addressed on this site before. However I poked around the search engine and couldn’t find what I was looking for. I am interested in what folks here have found in their research or casual reading regarding what may have been the longest ra...

Thanks Ulrich. It seems an odd way to present dispersion data. I'm going to go with my gut and assume the the curve presents 50% Zones as per my previous post -- i.e. the 50% Zone at 15000meters range has a length of about 140meters.
