counterpart. Operation Bellicose bombed the suspected Würzburg radar factory. The Operation Hydra bombing of Peenemünde did not affect the nearby Giant Würzburg at the Lubmin guidance and control station used for the V-2 rocket. Post-war use in astronomy Dutch scientists brought several of the surplus German coastal Würzburg radars to the Radio Transmitting Station in Kootwijk, Netherlands in the early 1950s. There, they were used in experiments important in the development of early radio astronomy, specifically the discovery of the Hydrogen line and subsequent mapping of the spiral arms of the Milky Way Galaxy. German radar equipment including two Würzburg antennas (obtained from RAE Farnborough) was used by Martin Ryle and Derek Vonberg at the Cavendish Laboratory from 1945 to observe sunspots. Two FuSE 65 Würzburg radars were installed around 1956 at the Ondřejov Observatory in Czechoslovakia. The first radar served until 1994 to measure solar radiation flux, later was moved to the Military museum Lešany. The second radar was used to measure solar spectrum in range 100-1000 MHz. Since 1994, it has been used only for occasional experiments.
