Air Intercept Air Intercept charts the history of Air Intercept radar. Air Intercept or Airborne Radar started in WW2 with the development of the Cavity Magnetron, by Randal and Boot. This enabled Radars to be made small enough to fit in aircraft. In the exhibition we have examples of the Radar displays used in the Mosquito and Beau Fighter during WW2 and the Lightning in the 1960’s and 70’s. We have models of the aircraft which were used for Air Intercept, through from WW2 to modern times. At the centre of the display we have an AI 23 radar used on the Lightning during the 1960’s and 70’s.
