"Zahme Sau" envisioned freeing the night fighters (now equipped with radar for the final stages of the interception) from the "Himmelbett" cells and allowing them to attack on their own. This was not all that easy, given the capabilities of the current generation of radars, but newer systems being developed would greatly increase the detection range and angles. In this role the existing cells created as part of the original Kammhuber Line would be used primarily for early warning and vectoring the planes to the stream.
