What were the German FuMB 6 Palau and FuMB 7 electronic-warfare suites used for?
Short answerTentatively, submarine radar detection and countermeasures, including warning, spoofing, or cluttering an attacking radar picture.
NotesThe answer begins with uncertainty about the suite names and their precise installation. Panelists associate the FuMB 6 and FuMB 7 equipment with German submarines and primarily describe radar detection. They also suggest an electronic-countermeasure role that could spoof or feed garbage data into an attacking aircraft's radar picture. Because the identification is explicitly tentative, the answer should not be read as a definitive technical specification.
