The missile Launching Area (Mederns) where the 3 missile launch pads can still be seen today - NE of the village of Mederns, about 10 miles North of Jever airfield.   The Integrated Fire Control (IFC) at Friederikensiel must have been situated SW of village ( buildings in white area).   The IFC was normally located some 900 to 5500 metres behind the missile launching area ( to the west).
