Re: Updating the KGV class

One has to consider that the Japanese were unwise to invest such enormous resources into only two battleships. The five KGV class ships made significant contributions to the ultimate Allied victory. This is particularly true in northern waters were operations by aircraft carriers were hampered by en...

Re: Updating the KGV class

It's easy to see the attraction of quad turrets because one then has 8 guns firing forward and 50% more guns in full broadside than a Bismarck or a Vanguard. However, as Sean points out, bigger turrets and mountings really require larger ships. Once one is dealing with a larger platform then it's a ...

Re: Updating the KGV class

Churchill was also critical of the KGV class and thought they compared unfavorably to the North Carolina, and sent memos to the Admiralty about it. The Admiralty replied that the KGV compared favorably on several factors. The KGV had heavier armour protection, and the aircraft hanger amidships did n...

Enigma enigmas during PQ17

One of the puzzling aspects to Ultra Intel during PQ 17 was that PQ 17 occurred during July 1942 but the German navy as a whole had gone to the M4 Enigma no later than Feb 2 1942. The literature generally agrees that this resulted in a naval Enigma black out of M4 messages until Dec 1942. Now compou...

Re: GEMA Radar Development

The TS1 was a close clone of the American 316A/B. The early cavity magnetron they were using proved too unstable in frequency for the type of radar they were developing, so they dropped the magnetron and went to triodes. (see page 43 of von Kroge's book) The context given for needing GEMA or NVA tec...

Re: Who won?

but returning to the Yamoto class ships which were considerably heavier in armament and armour than anything else at the time, would they really have been invulnerable to any battleship shell except perhaps an 18" from a similar sized ship (if one had existed on the allied side)? I just got through...

Re: Who won?

Another method to shift the balance from favoring the shell winning, and battleships having virtually no IZ at likely combat battle ranges, was to manipulate the striking angle.* Simply increasing armour thickness was not practical in most cases, so manipulating the striking angle could improve the ...

Re: Who won?

There were two basic concepts in play about how armour could defeat shells. One was that armour could destroy the shell or render it inert. The other was based on preventing effective penetration of a shell. The advent of Krupps Cemented Armour or face hardened armour meant that a shell would shatte...

Re: Who won?

This is a vast and complex topic! Who won? Neither completely won and neither completely lost. In the case of WW2 designs, it came down to the concept of immunity zone. The concept recognized the reality that no armour could defeat any shell at any battle range. However, it could defeat a given shel...

Re: French navy taken over by the kreigsmarine

In my opinion, it would have allowed the Germans to take a more direct hand on the course of the naval situations in the Med. This by extension may have changed the dynamics of the N. African theater. If the Afrika Korps and the Italians succeeds in N. Africa, and the Germans neutralize Malta, then ...

Re: British Type 284 gunnery radar

Radar engineer Brian Callick who was in the program: The transmitters ( 600 mhz ) used a variety of circuit configurations based upon a self-oscillator which defined the frequency of the radiated signal, sometimes with one or two stages of power amplification between it and the aerial system. Becaus...

Re: Prinz Eugen's hull

PG was torpedoed in Norwegian waters. Before returning to Germany the collapsed stern was removed and a transverse bulkhead installed, essentially converting the stern to a transom stern. The ship returned to Germany under its own power and steerage using the temporary transom stern. A new stern of ...

Re: Was the H.M.S Hood the most powerful ship for 20 years?

Yes, that is correct. It is difficult to quantify the effective thickness of Hood's deck protection compared to Nelson's effective thickness. The Hood used multiple relatively thin protected decks combined with an earlier standard of protective plating. The Nelson, used a single main armoured deck c...

Re: Bombing of the Tirpitz

The mining effect from such large high explosive warheads could have been catastrophic. There was the potential for a torpedo exploding several meters under the keel type of effect. Nonetheless, the Tirpitz was subjected to severe under water explosions when it was attacked by the X-craft and also d...
