Sometimes known as the Freiburg  FuMO 321 - 328: Based on the fuMO311 family of units but workig at 1.5 meters. FuMO 331: Naval designation for the FuMG 402 Wassermann M  FuMO 371: Naval designation for the FuMG 403 Jagdschloss  FuMO 201: Flakleit - Using Seetakt 80 cm technology a 3D radar mounted on an underground armoured turret ( originally an optical rangefinder) small numbers produced. Multiple antenna. Manufactured by GEMA. FuMO 211 - 213: Naval designation for the FuMG 62 family or radars - the Wurzburg A,C & D.  FuMO 215: See Reise. FuMO 221: Mannheim. FuMO 111: Barbara, 9 cm fire control radar based on modifying a FuMO 15 Giant Wurzburg to operate at 9 cm. Only experimental radars produced  FuMO 214: A Wurzburg Reise reconfigured for use as a naval radar with a range of approximately 50 – 70 km against surface targets. FuMO 215: Improved range version of the FuMO214. All though the Germans were carrying out research at centimeter wavelengths at the start of the war the work was abandoned as it was decided that the war would be over before the research & development could be completed. In February 1943 a RAF Stirling bomber was shot down over Rotterdam and a damaged H2S system was recovered. The Germans started a crash development program to use the information deduced from the captured system. Although a range of prototypes were produced, very few reached front line troops. Due to the device being recovered near Rotterdam, the Germans used that name in several code names for the Centimeter (9 cm) systems, such as "Rotterdam Device". Rotterdam: To get the quickest start with development, German industry copied, as far as possible, the H2S system. Approximately 20 systems were manufactured for R&D work. They led to the Roderich jammer and the Berlin & Korfu receivers. Jagdschloss Z: The 9 cm version of the Jagdschloss F panoramic radar system. Prototypes only. Forsthaus Z: The 9 cm version of the Forsthaus panoramic search radar. Prototypes only. FuMG 77: Rotterheim. A combination of the 9 cm receiver/transmitter of the Berlin system with the Antenna and other systems from a Mannheim.
