Hi Dave, If I understand correctly, this means that Seetakt was able to search surface targets, provide rangefinding for gunnery and also perform air surveillance. However, I don't understand how this could be done by a flat antenna: I imagine the whole rangefinder (armored aft) had to be rotated c...

I'm a bit surprised that Germans in 1943 had not clearly separated yet the tactical radar from the rangefinder gunnery radar and I would ask some clarification about the effectiveness of such choice...... Throughout 1943, the KM was waiting for the Berlin PPI radars. Although Seetakt was quite capa...

I don't use the FuMB numbers system to identify KM passive radar equipment. I only use the code names for antennas and receivers. The number designations will contain duplications. Antennas were given a FuMB number and also receivers were given FuMb numbers, each list starting with one. It can be ve...

Why all these passive radars ? Which were the corresponding radar sets used on board, apart from the antennas with their nice names There were so many passive antennas because the primary passive detection antenna was omni directional. It was omni directional so it could sound the alarm if a direct...

Scharnhorst was equipped with two new FuM027 sets during its stay at Brest. One at the foretop and one at the aft rangefinder. Prior to that it had only one FuMO22 set at the foretop. Also during the Channel Dash, Scharnhorst was equipped with a Timor passive antenna (FuMB7) on the back side of the ...

It is good to hear from you Tommy. I hope all is going well for you.

Gentlemen, Much has been said in other posts about the amount of 'dispersion' from the Italian Battleships guns, but it would seem that if two shells landed 'very close' to Warspite at the same range that Warspite hit, their gunnery cannot have been that bad! Or was it a couple of lucky shots? Luck...

Welcome back Byron.

The P-47 and the Zero had elliptical wings. The clipped wings versions of the Spitfire was done to increase the rate of roll. The Spitfire without clipped wings had a slow rate of roll, which put it at a disadvantage against the FW-190, particularly. The FW-190 had the highest rate of roll of any WW...

There has been a return to sanity: https://www.defense.gov/Portals/1/Documents/pubs/2018-National-Defense-Strategy-Summary.pdf It's like it never happened. Some comments by Anthony Watts: The new National Defense Strategy makes no mention of “global warming” or “climate change”. The document makes n...

I was expecting bearing measurement to be much less precise than an optical measurement (due to the width of the lobe) but I do trust your clarification of course. The Seetakt radars after mid 1940 used a type of fine bearing indication called radattel peilung. It was a phased array scanning of onl...

... and based on pure radar range (good), bearing (I don't know how good...) and estimated course/speed (quite bad with the radars of 1941, as radar is in its infancy for Germans too) . In the case of the FuMO27 radars on Bismarck and Prinz Eugen in 1941 this would be calculated by the fire control...

Less money in the people's pockets by any means is the same effect. It always retards economic growth and innovation. Energy subsidies in this case are transfer of wealth from the poor to the rich. So unnecessary. Moreover, the needed funding to keep the Navy solvent is a fraction of what is being w...

Germany has flushed billions down the drain and hamstrung its own economy through its Energiewende policies. All this has proven futile and has always been unnecessary. It boils down to priorities.

One more thing, it was reported that some of Rodney's shots were going well over, as the final range seems to have come down to 1 1/2-2 miles could meaning she could hardly miss, could that be some of her shells passing straight through the superstructure,which by all accounts was absolutely shot t...
