The FuMG 41/42 Mammut was a long-range, phased array, early warning radar built by Germany in the latter days of World War II. Developed by the GEMA company, it consisted of six or eight Freya antenna arrays, switched together and coupled to two Freya devices. The arrays were fixed and the beam could be electronically steered on a 100° arc in front and behind the antenna, leaving 80° blind arcs on each side. It was the world's first phased array radar[citation needed] and was able to detect targets flying at an altitude of 8,000m at a range of 300 km.
The British intelligence codename, "hoarding", was probably related to the shape of the large array.[citation needed] As late in the war as April 20, 1945, intelligence reports reflected the erroneous opinion that only development prototypes existed but no operational stations had been fielded.[citation needed]
