The Siemens & Halske T52, also known as the Geheimschreiber [1] ("secret teleprinter"), or Schlüsselfernschreibmaschine (SFM), was a World War II German cipher machine and teleprinter produced by the electrical engineering firm Siemens & Halske. The instrument and its traffic were codenamed Sturgeon by British cryptanalysts.
While it operated, it produced commodities vital to the German military forces before and during World War II. After substantial damage from strategic bombing, the firm and its remaining assets were dissolved at the end of the war. [214] As Germany deepened its commitment to World War II, Brabag's plants became vital elements of the war effort.
Siemens-Schuckert designed a number of heavy bombers early in World War I, building a run of seven Riesenflugzeug.Intended to be used in the strategic role in long duration flights, the SSW R-series had three 150 h.p Benz Bz.III engines in the cabin driving two propellers connected to a common gear-box through a combination leather-cone and centrifugal-key clutch in SSW R.I to the SSW R.VII ...
When Siemens & Halske merged parts of its activities with Schuckert & Co., Nuremberg in 1903 to become Siemens-Schuckert, Siemens & Halske AG specialized in communications engineering. During World War I, rotary engines of advanced and unusual design were produced under the Siemens-Halske brand, like the Siemens-Halske Sh.I and Sh.III.
German Army cryptographic systems of World War II were based on the use of three types of cryptographic machines that were used to encrypt communications between units at the division level. These were the Enigma machine, [1] the teleprinter cipher attachment (Lorenz cipher), [2] and the cipher teleprinter the Siemens and Halske T52, [3 ...
The company built airplanes during World War I, for example, this Siemens airplane in 1926 for Ernst Udet. Siemens & Halske (S & H) was incorporated in 1897 and then merged parts of its activities with Schuckert & Co., Nuremberg, in 1903 to become Siemens-Schuckert.
The most important difference from the Nieuport 17 was the powerplant - instead of the Le Rhone 9J of the Nieuport (licensed, as with the Oberursel Ur.II; and un-licensed versions of which were actually available in Germany at the time), Siemens-Schukert chose to use their own 110 hp (82 kW) Siemens-Halske Sh.I rotary engine - in which the ...
