Re: Alaska Class vs Dunkquerke Class

I believe that this was not the first time a US BB lost her radar through concussion (was it Washington?), it seems to be very fragile. It was a general problem with all radars of the WWII era, not just on American warships. This is because that was during the vacuum tube era. It is the nature of v...

Re: Alaska Class vs Dunkquerke Class

Hi Alberto, Yes, I'm aware of these differences. I put more weight on the French narratives and chronology of the battle than I do the secondary account, although I do not dismiss it. It is possible that the French remained unaware of some hits at the time, such as the alleged belt hit. It is always...

......at Casablanca. Gentlemen, I'm not familiar with that engagement, what actually happened? http://www.eugeneleeslover.com/USNAVY/USS_Massachusetts/War_Diary_13Nov_1942.pdf The Jean Bart was tied to the pier in Casablanca Harbor. It was incomplete and immobile. It had one 15" turret install...

Re: Yamato and Musashi

HMS Ark Royal was designed for welding as far as was possible: The ship was designed for the extensive adoption of welding. About 65% of the structure was welded (9) including the whole of the first 100ft from forward; the estimated approximate saving in weight as compared with riveting being 500 t...

Re: Yamato and Musashi

With the Deutschland class the difference was calculated to about 15%, unless my sources are wrong. This is more plausible than 2%, considering that riveting requires overlap joints and much more framing. You have to a make a distinction from hull weight (IE the part of the ship that can be welded)...

Re: Yamotoand Mushashi

The Yamato class design was based strictly on the strict all or nothing protection concept. Only the citadel, and turrets and barbets, were protected by armour, which was heavy. The main belts had a maximum thickness of 16-inches and were sloped 20*. This was capped by single armoured deck of 8-inch...

Re: Yamato and Musashi

Surely you meant Yamato and Musashi, Yamato and Musashi were the products of the IJN’s decisive battle doctrine. This doctrine was based on a hypothetical war plan with the USN. The idea was that the USN would need to sail across the vast Pacific to relieve an outpost (The Philippines for example). ...

Re: THE SCHWEINFURT/REGENSBURG RAIDS-AUG. 1943

To summarize 1st Schweinfurt: Hours before dawn German radio intelligence began recording and logging American radio traffic as the bomber’s ground crews tested their radio and radar equipment. This radio chatter continued as the bombers taxied, took off, and formed their boxes. The rule was radio s...

Re: THE SCHWEINFURT/REGENSBURG RAIDS-AUG. 1943

Thanks for the info, I'm sure that I read somewhere that there was supposed to have been a serious 'leak' of information before the raid which let the German defences to be ready when the bombers came over - have you ever heard of that theory? No, probably no intelligence leaks, but fog-both real f...

Re: Jasper, Schmalenbach and 6 salvos...

Hello Dave, You are the goto man in all matters of German radar, but how did a "hard wired solution" cope with sea clutter, spurious returns etc? There must have been human filtering, and possibly rejection, before numbers went in to the FC solution. The way the fine ranging system worked...

Re: Jasper, Schmalenbach and 6 salvos...

It is a difficult problem to solve using optical ranging, but not terribly difficult with radar ranging, which gave a near continuous stream of ranging data, rather than several ranges per minute as with an optical RF. Rowell may have witnessed Bismarck firing fore and aft salvos or two Gabelgruppe...

Re: Alaska Class vs Dunkquerke Class

The Dunkerque had a sloped belt while the Alaska didn't. Even if the French face hardened armour was as poor quality as American Class A, it should provide protection down to about 20,000 yards against the the 12"/50. The French deck armour should provide protection against the Alaska's 12"...

Re: Alaska Class vs Dunkquerke Class

The French 13-inch could defeat the Alaska's belt all the way out to 30,000 yards. It's difficult to see the Alaska's winning this one unless the Alaska's superior fire control enables it to knock out the Dunkerque before the French can score a significant hit. That is unlikely because the Dunkerque...
