Cryptanalysis of the Enigma bombes were, however, very fast and the most successful. They were extensively used by Bletchley Park over teleprinter links (using the Combined Cipher Machine) to OP-20-G for both 3-rotor and 4-rotor jobs. Although the German army, SS, police, and railway all used Enigma with similar procedures, it was the "Luftwaffe" (Air Force) that was the first and most fruitful source of Ultra intelligence during the war. The messages were decrypted in Hut 6 at Bletchley Park and turned into intelligence reports in Hut 3. The network code-named ‘Red’ at Bletchley Park was broken regularly and quickly from 22 May 1940
Enigma machine military circles. The word "enigma" is a Latin word, derived from the Ancient Greek word enigma (αίνιγμα) used in English, but not native German. Like other rotor machines, the Enigma machine is a combination of mechanical and electrical subsystems. The mechanical subsystem consists of a keyboard; a set of rotating disks called "rotors" arranged adjacently along a spindle; one of various stepping components to turn at least one rotor with each key press, and a series of lamps, one for each letter. The mechanical parts act in such a way as to form a varying electrical circuit. When a key
