Naval Enigma
Alan Turing
Statue of Turing by Stephen Kettle at Bletchley Park, commissioned by the American philanthropist Sidney E Frank.[31]
Turing decided to tackle the particularly difficult problem of German naval Enigma "because no one else was doing anything about it and I could have it to myself".[32] In December 1939,
Turing solved the essential part of the naval indicator system, which was more complex than the indicator systems used by the other services.[32][33] The same night that he solved the naval indicator system, he conceived the idea of Banburismus, a Bayesian statistical technique to assist in breaking naval Enigma, "though I was not sure that it would work in practice, and was not in fact sure until some days had actually broken".[32] Banburismus could rule out certain orders of the Enigma rotors, reducing time needed to test settings on the bombes.
