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 cipher machines in the German Army.
The Enigma machine was invented by German engineer Arthur Scherbius at the end of World War I. [4] The German firm Scherbius & Ritter, co-founded by Scherbius, patented ideas for a cipher machine in 1918 and began marketing the finished product under the brand name Enigma in 1923, initially targeted at commercial markets.

The US Army also produced a version of a bombe. It was physically very different from the British and US Navy bombes. A contract was signed with Bell Labs on 30 September 1942. [177] The machine was designed to analyse 3-rotor, not 4-rotor traffic. It did not use drums to represent the Enigma rotors, using instead telephone-type relays.
Between April 1942 and October 1943, at least 160,000 people were killed in the camp. Spring — Holocaust: the Nazi German extermination camp Treblinka II opens in occupied Poland near the village of Treblinka. Between July 1942 and October 1943, around 850,000 people were killed there, [1] more than 800,000 of whom were Jews. [2]
It was Germany's secret military police that was organised by the German high command (OKW) in July 1939 to serve with the Wehrmacht. It was mainly designed to carry out security work in the field, as the executive agent of the Abwehr. Geheimfernschreiber – (literally, "secret distance writer") cipher machine. Gelbkreuz – mustard gas
Military Enigma machine, model "Enigma I", used during the late 1930s and during the war; displayed at Museo scienza e tecnologia Milano, Italy. 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.
The nations involved fielded a plethora of code and cipher systems, many of the latter using rotor machines. As a result, the theoretical and practical aspects of cryptanalysis, or codebreaking, were much advanced. Possibly the most important codebreaking event of the war was the successful decryption by the Allies of the German "Enigma" Cipher.
The Lorenz SZ42 machine with its covers removed. Bletchley Park museum. The Lorenz SZ40, SZ42a and SZ42b were German rotor stream cipher machines used by the German Army during World War II. They were developed by C. Lorenz AG in Berlin. The model name SZ was derived from Schlüssel-Zusatz, meaning cipher attachment.
