Kunersdorf Communications Bunker ~ Project Code: 448 ~ Callsign: “Nutzlast” The Kunersdorf communications bunker was planned in the 70’s, under construction until 1981 and, following a trial run in March 1981, it was in constant operation as the secret radio transmitter site for the main C3 (command, control, communications) bunker of the East German (EGER) ministry of defence (MoD) in Harnekop until 1991, when it was decommissioned. The facility was an integral part of Maintenance Unit 12 in Harnekop and was described as a weather observation station to conceal its real purpose. The bunker had eleven unmanned transmitter sites, each equipped with two KN1-E 1 kW shortwave (SW) transmitters (right), which used buried antennas. These transmitter buildings were described as “Sputniks”, remote (static) transmitters, but mainly as “electrical utility sites”, and were located over an area of some 500 km² in the Oderbruch. Following commissioning in 1981, the site also became the main control centre for switching and onward transmission of morse, printer and voice comms via cable from all points in the GDR and, as a result, was directly subordinate to the Chief Signals Officer in the MoD and operated as an independent unit. In 1983 it started transmitting the high altitude weather reports for the EGER armed forces (NVA). One of the reasons why SW transmissions were used so extensively was primarily because of the presence of an obsolescent basic national cable grid and the lack of sufficient funds to upgrade it extensively. Bunker data Degree of protection (GDR standards): C (B) Outer dimensions Length 37.5 m ~ Width 23.4 m ~ Depth (total) 13.6 m EMP protection Cable entry, telephone exchange and water tanks in the waterworks are metal lined, and low-frequency cables have overvoltage protection. Blast cap 2.1 m thick Foundation slab 1.5 m thick Intermediate floor 1.3 m thick Outer wall 0.9 m thick Bunker roof 0.6 m thick, Level -1 3.60 m, Level -2 3.3 m high Cooling water requirements: some 67 m³ / h The bunker could be hermetically sealed for up to 36 h If you have any further questions, please feel free to contact us: phone-mobil: +49171 7490224 E-Mail: info@bunker-kunersdorf.de
