Allied Countermeasures
The Allies were able to jam and track the early FuG 202 and 212 sets by Summer 1943. During several months in this period they rendered these sets almost useless by blinding them with 'Window', known as Düppel to the Germans of WW II, and today known as Chaff. Fully jamming the SN-2 took longer but was probably accomplished by the Allies in late 1944 or early 1945. Much more dangerous were Mosquito intruders equipped with a device called Serrate to allow them to track German night fighters by emissions from their Lichtenstein B/C, C-1 or SN-2 sets.
An aerial maneuver known as the 'corkscrew' was developed to remove an attacked heavy bomber from within the 60-degree cone of coverage of an attacking night fighter's Lichtenstein radar. The technique was developed using the same early model UHF-band Lichtenstein-equipped, Ju 88R-1 night fighter that had landed at RAF Dyce in April 1943 by its defecting crew. It was also later flown in tests by the RAF's enemy aircraft evaluation unit, No. 1426 Flight, known colloquially as the 'Rafwaffe'.

Famous quotes containing the word allied:
“Our security depends on the Allied Powers winning against aggressors. The Axis Powers intend to destroy democracy, it is anathema to them. We cannot provide that aid if the public are against it; therefore, it is our responsibility to persuade the public that aid to the victims of aggression is aid to American security. I expect the members of my administration to take every opportunity to speak to this issue wherever they are invited to address public forums in the weeks ahead.”
—Franklin D. Roosevelt (1882–1945)
