The Siemens and Halske T52, also known as the Geheimfernschreiber ("secret teleprinter"), or Schlüsselfernschreibmaschine (SFM), was a World War II German teleprinter cipher machine. The machine and its traffic were codenamed Sturgeon by British cryptanalysts. While the Enigma machine was generally used by field units, the T52 was an online machine used by Luftwaffe and German Navy units, which could support the heavy machine, teletypewriter and attendant fixed circuits. It fulfilled a similar role to the Lorenz SZ 40/42 machine in the German Army.
