Re: Tribal class dd

I had a feeling that that was what you were referring to. You have to remember that these documents were summaries being given fleetwide distribution to NON-specialist officers. The REAL gunnery documents (both internal and for distribution to the fleet) ALL SEEM to have disappeared. Much ( NOT ALL...

Re: Tribal class dd

That is an interesting acronym I haven't come across before, could you tell me what it stands for and the reference of where they are available, Thanks. ..... Sorry about that, Phil. Especially as I rail on endlessly that rampant use of acronyms is a portent of the end of Western civilization. PiNG...

Re: Tribal class dd

Another option is to consult contemporary archival documents (PiNGs for example), writings of those who were professionally involved with such matters (DK Brown for example), studies of academics with the necessary scientific credentials (N Friedman, D Mindell) and proper historians granted access t...

Re: Tribal class dd

Re the HACS versus Mk37 issue, readers with an interest to get an objective assessment are recommended to read the Admiralty wartime PiNGs, Friedman's recent book on AA, DK Brown's "Nelson to Vanguard" and Edgar March's "British Destroyers".

Re: USS Massachusets V Jean Bart

I haven't read Jordan & Dumas. Do they describe how the sections of Jean Bart's main deck were fixed together? For example, South Dakota or Iowa's main deck consists of 4.75 inch plates laid on top of 1.25 inch plates (with a 5/8th inch plate below), King George V has either 200 lb plate or 160...

Re: USS Massachusets V Jean Bart

"French Battleships 1922-1956" by Jordan & Dumas offers detailed coverage of Jean Bart's damage, with info sourced from the original French post-battle damage report. My theory (subject to confirmation when/if I ever get the time) is that Jean Bart may not have been perfectly upright a...

Re: The Plot

Re optics and vision - the principal governing factors are relative light and meteorology conditions. If those are against you, the best optics in the world will count for little.

Re: Tribal class dd = HACS vs Mk37

The RN was certainly influenced by the USN's overclaiming but I've never read of any real systematic study by the RN comparing the two. Certainly from our perspective, there appears to be little difference between the actual results achieved by the two systems. ..... It is not really necessary to p...

Re: Tribal class dd = HACS vs Mk37

The HACS versus Mk.37 controversy was done to death earlier this year on the Naweaps BvB forum. My opinion, for whatever anyone thinks it's worth, is as follows: the only party who took any real time to analyze and compare the two systems side by side on a technical hands-on basis was the Royal Navy...

Re: The Climate Change agenda

Well, I spent 14 years at Purdue, and I met a lot of people working on this problem. I'm a historian by trade, I work for the Navy Department, but I got interested in AGW while working as a research assistant for a professor with few computer skills. I sat in on meetings that would inform me of the...

Re: The Climate Change agenda

Yep. Sure. I'd be utterly fascinated to learn exactly what has convinced you of the correctness of the claims of the school of anthropogenic climate change. I am referring to the "settled science" of the old school of anthropogenic global warming, which has now become the new school of an...

When were the last celestially accurate positional fixes (as opposed to dead reckoning estimates) obtained by PoW, Norfolk and Suffolk prior to the engagement?
