| Abstract: | The wiring of rotors in the naval version of Enigma is given (including that of beta and gamma) and events leading to the introduction of Triton, a cipher for Atlantic U-boats, are described. It is shown that an alpha rotor did not enter service, and that Triton became operational in October 1941. |
