The four-rotor Enigma machine, introduced by the German Navy in early 1942 and shown here with its casing open, overwhelmed British codebreakers with its message-scrambling capabilities. The new naval system, called Triton by the Nazis and M4 Shark by the British, led to a near blackout in reading U-boat radio messages until December 1942. Photo courtesy of the National Archives
