In the depot of Deelen Airbase Museum we are currently restoring our Würzburg Riese radar.
Würzburg-Riese was during the Second World War, the German code word for the 1941 radar installation FuMG 65, developed by Telefunken 65. The 15 tons monster had a parabolic dish 7,5 meters diameter (built by the Zeppelin factories in Friedrichshafen), could be rotated and had an elevation- and a azimuth axis. He was operated by six men. With this installation, with a wavelength of 54 centimeters, and could be set to within a quarter of a degree, the distance, direction and height determined from aircraft could be determined around 70 kilometers away.

The Giant was actually the bigger brother of the smaller Würzburg-radar with a smaller distance range. During the war, an estimated 1500 of these "Riesen "were built. They were an important part of the so-called Atlantic Wall, the German defense line along the coast between France and Norway, and as such they have contributed to the loss of many allied aircraft over Western Europe. Along the Dutch coast, about forty of such radar systems were operating day and night, usually in pairs: one for tracking of the enemy's heading, and one for guiding the own nightfighters.
Curious citizens were told that these were hearing devices: "They are highly sensitive microphones, who hear the English planes arrive '. Radio Radiation from the Milky Way. Most radar equipment disappeared shortly after the war in the furnaces, but some were saved, converted and used for scientific purposes.
3 Wurzburg Riesen are left from a total of approximately 40 in the Netherlands. One in Overloon, one is in Berlin and the 3rd is owned by Museum Deelen.
