Re: Damage to German warships in Brest

Schmalenbach included a drawing detailing the damage to PG in his Under 3 Flags book (pg142). The bomb hit just inboard of the intersection of the oberdeck and the side plating. A few inches outboard and it would have missed. A few feet inboard and the damage probably would not have been as signific...

Re: The Swordfish's Torpedo misses Bismarck

It was not until September that attacks on the German warships were resumed with each quarter moon phase, obviously only at night. The attacks were much larger in scale with about 150 bombers per raid, and included more and more four engine heavy bombers carrying more and/or larger bombs. Moreover, ...

Re: The Swordfish's Torpedo misses Bismarck

July 23. The location of Scharnhorst had been confirmed by a recon flight on July 23 in La Pallice, 200 miles to the south. Scharnhorst was running machinery trials there. Some secondary sources claim that the scheduled night raid on Brest was moved to the next day to ensure hits in an attempt to si...

Re: The Swordfish's Torpedo misses Bismarck

The first raid against S&G occurred on the night of March 30/31. 109 bombers were sent. They scored no hits. Examination of the bomb fragments indicated the use of armor piercing bombs, leaving no question of the intentions. April raids on Brest: April 3/4 90 bombers. Target area not found. 3 lost. ...

Re: The Swordfish's Torpedo misses Bismarck

Regarding the question of how Bismarck may have fared in French Atlantic ports, and the capabilities during 1941 of RAF Bomber Command: During the last few years I have been interested in researching Bomber Command’s operations during 1941. I was surprised by some of the findings. The arrival of S&G...

Re: Updating the KGV class

Accounts of Prince of Wales operations in the tropics indicate that the KGV's were poorly suited for operations in such environments. They were not equipped with air conditioning and ventilation below decks was poor. In fact the crew engaged in unauthorized ventilation improvements which probably co...

Re: Updating the KGV class

Thanks to you both for the info, it makes interesting reading. I'm sorry that I have strayed way off topic here,perhaps it should go back to the 'Shell v Armour topic. But as we are here, I'm not sure at what range these tests were carried out, presumably as they were only aiming at a small piece o...

Re: Updating the KGV class

The obsolescence of the British and American battle fleets was driven by foreign developments of more powerful ships and aircraft. Hood's armor is good against Scharnhorst's 11 inch guns but overmatched by the Bismarck's 15 inch guns. I can't see how building 14 inch KGV's and NC's makes the Yamato...

Re: Updating the KGV class

None of the 35,000 ton treaty battleships were worth building in view of the international arms race in the late 1930s. The Japanese were expected to build 16 inch/46,000 ton ships to complement the Nagato class. The Italians already built 15 inch/40,000 ton ships. Then the Bismarck 15 inch/44,000 ...

Re: Updating the KGV class

As an aside, I also asked if the KG's had been built with 12 x!4" (and all working properly!) would they have been a match for most of the ships of other countries, except perhaps the Iowas and Yamatos? They didn't need 12- 14" guns to match up with contemporary battleships. They matched up good en...

Re: Updating the KGV class

Gentlemen, I'm going to try your patience once again! Going back to the original question of updating the KG's. In an earlier post which seems to have got lost in the debate about the seaworthiness of the KG class, I asked why that it was possible to build the 'Nelsons' with 3 x 16" turrets and sti...

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 ...
