Weather Station Kurt (Wetter-Funkgerät Land-26) was an automatic weather station, erected by a German U-boat crew in northern Labrador, Dominion of Newfoundland in October 1943. Installing the equipment for the station was the only known armed German military operation on land in North America during the Second World War. After the war it was forgotten about until its rediscovery in 1977.
Weather systems in temperate climates predominantly move from west to east. This gave the Allies an important advantage. The Allied network of weather stations in North America, Greenland, and Iceland allowed the Allies to make more accurate weather forecasts than the Germans. German meteorologists had weather reports sent by U-boats and weather ships, such as Lauenburg, operating in the North Atlantic. They also had reports from clandestine weather stations in remote parts of the Arctic and readings collected over the Atlantic by specially equipped weather aircraft. However, the ships and clandestine stations were easily captured by the Allies during the early part of the war. Data from aircraft was incomplete as they were limited in range and susceptible to Allied attack. Regular weather reporting by U-boats put them at risk as it broke radio silence, allowing the Allies to locate them and track their movements by radio triangulation.
To gather more weather information, the Germans developed the Wetter-Funkgerät Land (WFL) automatic weather station. It was designed by Dr. Ernst Ploetze and Edwin Stoebe. Twenty-six were manufactured by Siemens. The WFL had an array of measuring instruments, a telemetry system and a 150 watt, Lorenz 150 FK-type transmitter. It consisted of ten cylindrical canisters, each 1 metre (3.3 ft) by c.47 cm diameter (1.5 metres (4.9 ft) circumference) and weighing around 100 kilograms (220 lb). One canister contained the instruments and was attached to a 10-metre (33 ft) antenna mast. A second, shorter mast carried an anemometer and wind vane. The other canisters contained the nickel-cadmium batteries that powered the system. The WFL would broadcast weather readings every three hours during a two-minute transmission on 3940 kHz. The system could work for up to six months, depending on the number of battery canisters.
