Re: Graf Spee trying to escape back to Germany...

I believe Raeder was promoted Admiral and posted commander-in-chief of the Reichsmarine in 1928. During the Hitler era he was promoted Generaladmiral in 1936 as the Navy began to grow in size and in April 1939 received his Grossadmiral's baton from Hitler.

Re: Need Technical Assistance for a WWII Action Novel

I can tell you a few things about the Clemsons: Generally, the major faults with the 4 stackers were relatively short range although this was negated by the post WW1 introduction of underway oiling; very wet boats forward due to the lack of sheer and flare to the bows; fairly wide turning radius due...

Re: Royal Navy became oil-addicted thanks to Churchill

In some navies, such as the German Imperial Navy, larger ships frequently had a mix of oil and coal fired boilers--i.e. Derfflinger for instance had 8 oil fired boilers and 14 coal fired ones. This arrangement was planned for the RN R class battleships, but the idea was nixed by Fisher who insisted ...

Re: Royal Navy became oil-addicted thanks to Churchill

I could be mistaken, which of course would not be the first time, but I have been under the impression for quite a few decades, that the oil carried in coal burning ships was largely used to help light up the boilers, but i suppose could be sprayed into an already lighted up boiler fire box to produ...

Re: Martini Henry rifles

Hi Paul, Another little bit of info came my way via John Sukey, a collector of my acquaintance. It would appear the modified original breech blocks, which had a new face dovetailed in and a sleeved firing pin chamber caused most of the problems, as the dovetailing milled away the casehardening, allo...

Re: Martini Henry rifles

A little more info came my way concerning the breech blocks. On conversion, a sleeved block for the smaller firing pin was used as well as a new facing of the breech block to fully support the smaller rimmed 303. Apparently, while the older 577-450 base was adequately supported by original blocks, t...

Re: Martini Henry rifles

I know Enfield barrel Martini's usually came with a new breech block having a smaller diameter firing pin so as to avoid the possibility of rupturing the primer. It was found that the older, larger firing pin tended to do so due to the higher sustained breech pressure. It is also possible that the r...

Re: Hood v Vittorio Veneto

To the best of my knowledge, the firing trials against Hessen were conducted with nose fuzed shells instead of the much more expensive and difficult to produce base fuzed HE and AP. Consequently, there would be little penetration of armour

Hi Wes,

You might take a look at:

To my knowledge, the bomb was actually a converted 16-in shell with a filler of trinitroanisol.

Re: Bismarck firing procedures at DS

I don't think there are too many mysteries in Bismarck's relatively low rate of fire. Because of the converging courses of the two squadrons, there was a fairly rapid rate of change taking place which would have to be checked and accounted for, and probably Schneider was taking his time to mark fall...

Re: Bismarck firing procedures at DS

fire for effect would have been normally turret groups, A+B, C+D at regular intervals. Delays or long pauses would be if the MPI wandered off target requiring a correction.

Re: Bismarck firing procedures at DS

In the case of Bismarck, it was actually preferred that the three Gabel Gruppe salvos be fired with turret groups. This was because four shells were better for determining mean points of impact, since it was possible for two shells to fall in line and be difficult to tell one from the other, or one ...

Re: Bismarck firing procedures at DS

Both guns elevated individually and fired independent when reached the individual calculated firing angle. A delay coil between the guns was not necessary. This would be true when the guns were set to fire an an arbitrary angle as the ship turned or if rolling heavily, and at times when the firing ...

Re: Bismarck firing procedures at DS

Bismarck's fire control system was highly automated in some respects, particularly when operating in central fire control mode, and I suspect that with a fairly new crew and without the usual intensive gunnery training while steaming underway, Schneider may have preferred to let the automated gyro s...

Re: Bismarck firing procedures at DS

Alberto One last question: are Germans ALWAYS firing together the guns in a single turret or are you aware of special circumstances when only 1 gun in a turret can be ordered to fire ? Thanks in advance for your help here..... Bye, Alberto Generally speaking, the two guns in a turret would be fired ...
