Artillery Fire Control Equipment

[John Hilly]

I discussed with the sysop copying the posts on fire control to another thread. We may do that, tho the number to copy grows daily

Meanwhile, I managed to post a new one down here: http://forum.axishistory.com/viewtopic. ... 8#p1214693

Merged are a dozen+ posts concerning Red Army fire control equipment/tool from another thread. They should provide some interesting comparisons between them & the other equipment posted earlier.

hi there,
i hope someone can recognise the panel below...
it's found next to the FL311 of the SS flakbatterie in stutzpunkgruppe Scheveningen.
direct next to it was a wurzburg D.
i tried searching the internet but nothing found so far..
it's about 68 centimeters wide, 40 centimeters deep.. the way it's fabricated it really looks like german equipment.

there are 2 small rectangular things above each of the big holes, it looks like they are for a row of numbers (like a adjustable date stamp..)

thanks in advance, Tim

I am a bit curious also.

If indeed it is a Würzburg you may be able to identify the bit on the pics attached.

Hi ses, the below picture is actually the wb. Of this batterie just after the war
I studied alot pictures of this type wb. But nothing matched.

Hello,

I have a Rechenscheiber 34. I do not have the aluminum box it comes in. The picture is too large to post here. If you would like to see it. please email me at [email protected].

Hello,

I'm doing a data circulation diagram between the equipments I know and I would need some information.
-The Langbasis-Kleingerät and the Langbasis 42 have the same role, yes or not ? I think it is the case and the Lanbasis 42 is a older system or used to fill the lack of modern Langbasis-Kleingerät.

-Can the E.U. Messer also give the future azimut ? All sources do not converge on this point.

-The distance obtained by the Leitstand's rangefinder is not necessary for the calculations made by the Langbasis-Kleingerät, can someone confirm this point ?

Many thanks

Regards

A few words about the Lang-Basis-Kleingerät C/36.
Common for German Naval Shore based system were that the C/36 equipment was supposed to work with among others the C/37 components and was later coupled with the Epa-Seipa C/39 system. This led to further development of the LBK C/36 giving features that overlapped the other equipment, so one had to make sure that the correction input was only made on one of the instruments.

The main use of the LBK C/36 was to use one Leitstand and one Peilstand (Lang-Basis-Verfaren). Th two stations indicated azimuth values of the selected target to the LBK, (and observations of fall-of-shot to the Au-Au C/40). An educated fire control officer had to be at the Leitstand. Using only azimuth values from the two stations the LBK was automatically generating course and speed of the target. This was related to the actual time-of-flight, giving a predicted range and azimuth to the posistion the target was supposed to be in at the impact of the shell. This data was sent to the gun(s) by means of an azimuth transmitter (on the newer LBK C/36, or on the Epa-Seipa C/39 if it was an elderly version of the LBK). The range was transmitted via the Epa-Seipa C/39 system. Corrections of the day were taken from the C/37, and put into the LBK system only at the start of an engagement.
Using the One-Station system was the first reserve solution for use of this equipment. The Peilstand was omitted and the optical Rangefinder (for heavy batteries usually a 10,5 meter RUEM) came into use. Any Peilstation with an optical rangefinder could also act as an One-Station data provider, but an educated fire control offiser had to be present at that station.
Other means of Fire Control was the use of an Airborne spotter, not very widely used due to the fact that there really were no planes with educated personnel around. Late in the war there was some use uf FuMO 214 as a data provider but was not a working solution.

The LB C/42 M (Navy version) and M 42 H (Army version) was a much simpler system, more like a plotting board - no automatic calulation of target speed and no electrical connetions.

As far as I know the planned successor of the LBK C/36, called the C/40 newer made it past the design and prototype level.

Hello JEF,

I was pretty sure you'll answer, thank you very much.

I have a german manual from the Heer about Langbasis Schiessen against naval targets where there are only a L.-B.-Gerät 42 (H) and a E-Uhr 42 in the plotting room but it must be a very rudimentary configuration.

Some Ebay picture's from the writers of the Seacoast Defenses , looks like private shots or extra that were not used in the report .

Nice, the charts show Hanstholm and the surrounding measuring posts.

Hello,

On the Zielsäule S 2 C.40 there is a "Schuss Entfernung" dial. I'm wondering what is the rôle of this dial given that the optics mounted on such material are not range-meters. Does the displayed range come from the main range-meter ?

Thanks.

First of all, the C/40 is a part of the 110 volt system used in heavy batteries. On top of the C/40 one finds the dual-purpose periscope for target azimuth and spotting periscope for the Fire Control Officer. The mentioned dial is on the side where the Fire Control Officer is located, and provides him with range data. The dial shows the range data sent from the range finder to the Plotting Room.
