Re: KMS BLUCHER
Old rule, it is difficult to sink a ship by gunfire alone. For sure the torpedoes were the main culprit.

Re: Pom pom with director Mk IV vs Bofors 40mm with Mk 51
2) With continuous radar ranging the GRUB (computer could (and must) calculate true target motion otherwise radar ranging would actually make predicted target position more inaccurate, So you mean that if in the second sweep the radar detects the plane closer (or farther) to the ship the computer w...

The Corsair in the War Zone by Ralph Delahaye Paine is a recently added book on Project Gutenberg ( https://www.gutenberg.org/ebooks/72760 ). The Corsair was J.P. Morgan's yacht, offered for and accepted into naval service during World War I. The ship escorted convoys (mainly in the Bay of Biscay),...

Re: Blucher in Dogger Bank
Hi guys. In this battle Blucher was abandoned by the rest of the German ships, that could (orders notwithstanding) have stood by her. Was there any other case of a fellow ship left alone like this (in any war in the steam era)? Regards I’m only four and a half years late here 🤪, but the German ligh...

Re: Pom pom with director Mk IV vs Bofors 40mm with Mk 51
1. Seems like the pom-pom director is more similar to a non-disturbed line of sight director as per Friedman. This means that there isn't a reticle that provides a suggested aim off like a gyrosight, rather the correction from angular rates, range, are added directly to output of the director. But ...

Re: Pom pom with director Mk IV vs Bofors 40mm with Mk 51
The bes picture can find for a MkIV director from the front shows some kind of stabilised telescope, I have no idea how the CO can apply lead through that . I have a suspicion that the details are hidden away in some documentation that will never see the light of day... Hi! In the Mk14-Mk51 the lea...

Re: Differences between 10,5-cm (4.1") Krupp Naval guns S.K. L/40 and L/45?
Hi Marcelo, I'm not sure I understood your question exactly. During the translating into another language, there are always misunderstandings. (Fortunately this time we didn't have any back translations from Turkish into English - :wink: -) I am also not an expert in this metallurgical field of wea...

Re: Differences between 10,5-cm (4.1") Krupp Naval guns S.K. L/40 and L/45?
For the second, I meant that the Norway gun has an upper and lower dumper, besides the lack of muzzle thickening. The Turkish gun has only a lower dumper and muzzle thickening. Regards Hi Marcelo, Regarding the different muzzle shapes of the two guns, we both agree. Regardingh your fourther comment...

MARCELO - !!! Please; - are you serious or are you kidding me? ( . . . or you have had one bottle “ Lequi Liquor “ to much? - :D - :angel: - :lol: ) The gun in Norway has no muzzle thickening but also a second bumper on top. The thickening at the muzzle had nothing to do with the recoil brake. So i...

Hello Marcelo, Basically, I am already convinced that both photos you posted represent a 10.5-cm Q.F. L/45 Gun-Barrel . Both photographers, Bayram Akgün and Nils Mosberg, have been dealing with this topic not since yesterday and are actually very credible when they make such a statement. In my opin...

Re: Differences between 10,5-cm (4.1") Krupp Naval guns S.K. L/40 and L/45?
Hi Holger. The only gun that we can be sure (because it was measured) to be a /45 is this one: https://i.postimg.cc/MKYBW7v0/2.jpg Then we have this one. It has no muzzle thickening, it is a monoblock gun, but it can be any other model, or even another calibre. I would like to see the markings in th...

Bad weather sailing: turrets pointg to the sides
Hi guys! A common view, a warship sailing in bad weather with the guns pointed to the sides. Common knowledge says that this is done so the water would not poured into the turrets. But there would be a not so easily understood phenomena. Pointing the guns to the sides increases the so called moment ...
