Re: GHG and the related warnings

Franz Kohlauf T-23 Torpedoboot utilised its GHG scouting for British cruiser destroyer forces employing the "Tunnel" tactics on Oct 23 1943. Reportedly 15 minute before the British got radar contact at 14,000 yards , Kohlauf's boat got a GHG contact near the key waypoint of "The Tunnel" route. The d...

Re: A KGV in the south atlantic 1982 ?

They look like Exocet SSM launchers. More to the point, if RN was stupid enough to keep KGV into the late 1970s they would never have left the secondaries as 8 twin 5.25" guns. The only real purpose of secondaries in such a role would be to make up for desperately poor AAA. The four SEACAT GWS 22 w...

Re: Variable pitch propellers

Pretty sure the Germans used variable pitch propellers on their Uboats or at least planned to do so.

Re: Graf Spee cover-up

The problem is, that you can find hints on engine problems, but no throughout examination of the DEUTSCHLAND-class vessels propulsion system. As far as I can tell from my sources, the main problem was, that Diesel engines were, at least for vessels of that size, a rather new, unproven technology. T...

Re: Some data on German AA radar R&D

If these Radars were also passive why the need to also develop a range of radar detectors?

Re: River Plate: conflicting track charts

That kind of error seems common. At the same time the German secondaries were being misdirected the British Light cruiser fire was also being miss directed by their spotter plane that mistook one ships shell splashes for the other and corrected accordingly.

Re: River Plate: conflicting track charts

Yes but its main task and training was firing the 11 battery. Its one of the explanations for the poor performance of the 6" guns.

Re: River Plate: conflicting track charts

I recall some one posting that the 6" secondaries on the AGS had no dedicated director , instead they had a sub plot from the main 11" Gun directors that could direct fire...if the staff had time. However since the 11" ballistics where no were near the 6" gun ballistics - this direction was not of m...

Re: River Plate: conflicting track charts

You are actually suggesting that the British cruisers engage with the idea of getting their speed reduced so they can't shadow AGS? Really? Of course not ,they would fight for as long as the had to.... any cut off point for engagement would be if Exeter sinks or all three ships are crippled and tur...

Re: River Plate: conflicting track charts

How does one "run down" two cruisers that are faster than you are? Simple you give them a compelling reason to stay. Langsdorf just continues to close with the Exeter and torpedo her until she is sinking. Harwood will have no choice but to battle to the ailing cruisers side and in doing so subjects...

Re: River Plate: conflicting track charts

Definitely finish off Exeter and batter the other two cruisers since they have to rush to the aid of a sinking Exeter. That's the only way to ensure they can't shadow the AGS thus effecting an escape. The point is not moot since the entire KM doctrine was riding on the out come of this first clash. ...

Re: Yamato + Musahi - Damage taken

I can understand how a torpedo hit on a rudder could be 1/2 % but not 6%? Looking at the diagrams of the Bismarck event it seems like a 10 meter section of hull was hit . If this is what was required to jam the rudder into the screw, then that's 10m out of a 250m hull length or 1/25th of the hulls l...
