I wonder how widespread radiolocation and flight assistance systems were in the Luftwaffe during the Second World War and on various fronts.
A radio direction finder (RDF) makes a fine show on the dashboard of all Bf 109 and Fw 190 models, at least starting from 1943; but how much this device was reflected on the ground in terms of radio beacons (NDB) and Blind-Landing Beacons (Lorenz)?
