FuSE65E Giant Wurzburg mounted on a 'goods train wagon'* (Würzburg Riese Eisenbahn-Ausführung) The IFF antenna array being temporarily pointing towards the rear-side (slightly visible at the top section through the reflector mesh)    * Thanks to Jan ten Have and his friends they finally came with the best word:  'goods train wagon'.

Aufbau- und Bedienungsvorschrift

Railway version of the Giant Wurzburg radar

D. (Luft) T. 4507/6

March 1944 (März)

Nur für den Dienstgebrauch



In my perception significant and unique is - that the pictures are showing how the Giant Wurzburg was transported and being assembled for operations. One gets the impression that it was quite simple to be assembled. Not a too great deal, as all was kept modular!

Ernst Wagner's original pdf copy is just over 20 MB, and too big for the internet to be downloaded at once. For this reason I have divided the file into three parts, of which even one is just over 10 MB, owing to the incorporated photos.



D.(Luft) T.4507/6-1 Part 1 (pages 1-20, please notice that pdf page 1 is the front cover page, thus not equal to the document page number!) (9.7 MB)

D.(Luft) T.4507/6-2 Part 2 (pages 21-42) (10 MB)

D.(Luft) T.4507/6-3 Part 3 (pages 43-65)



The Giant Wurzburg prepared for railway transportation

Würzburg-Riese, Eisenbahn-Ausführung

This mobile configuration allowed the deployment of a complete Giant Würzburg radar station at any railways site


Preparing the Giant Wurzburg antenna-dish to be mounted onto both hinge frames


The apparatus and control cabin is to be brought on its place


A rare detailed photo of the IFF antenna array (Kennung: Kuh-Gemse). Viewing it from the rear side of the antenna-dish (mirror). The two dipoles nearest to us are both acting as reflectors. Please notice the fine structure of the reflector mesh!


Detailed pictures of the various interconnections onto (and from) this Giant Wurzburg radar installation. Connectors 9 and 10 are most likely for the FuSE65 radar and for the IFF antennae signals. Viewing their size, I guess, that number 9 is for the radar signal (receive and transmit) and number 10 is meant for the IFF operation (although, according the table on document page 32, not equal to the pdf page numbering, might causing doubts, I am still confident that cable connection number 9 is the one used for the radar signals).     The upper photo is concerning the power cables, I guess, that the flat central connector is being meant for 3 phase power line (3x380V, max 17A, power requirement 12-15 kVA) and the rest is concerning operational data, like used for the transmission and/or operational parameters. Most likely firstly linked onto Ü-37 (Servos which are being phase-error-controlled repeaters). Please regard also ekm-Rechner.     These round heavy connectors were known as 'Renk-Stecker' and where having a wide range of pin configurations, as to prevent for incorrect interconnections . The upper shown connectors were mounted at the fixed-base-frame-chassis (please notice the second photo), so that the Giant Wurzburg could rotate on its pivot freely, thus not being hampered by cable restrictions what so ever. (Schleifring-Übertragung).     Please notice the cover-nut shown down/right, which is carrying character '6' whereas the connector is carrying number 9; the cover-nut is meant to be mounted upside-down, when no cable is connected!

According this document, this radar installation accounted for a weight of about 25 tons!


Please consider the integral manual (divided into three parts) for more pictures and details.


Mr. Ernst S. Wagner kindly allowed us, among this one, copying several very interesting German military wartime manuals and descriptions!
