The Nazi Naval Officers never dreamed the Allied Forces would get their hands on an Enigma machine and the instructions to the machine. They thought their code system was full proof since the machine did an exceptional job of doing code. They did not realize the Allies could decipher all their code. Once they began to suspect the Allies had figured out their code they had to alter their methods.

Certainly the Japanese Naval leaders believed they could cripple the US Naval fleet but they messed up when they failed to bomb the aircraft carriers in Pearl Harbor. They also did not realize the Americans had other ships elsewhere and could also rebuild or build new ships. The Japanese thought Americans were wusses and dopes. They did not understand their enemy.
The naval race began in 1906 and lasted until 1914 and created great friction between Britain and Germany it was one of the major causes of wwi! :)

Enigma was the German coding machine. JN-25 was the Japanese Naval code.
Enigma messages were sent by radio telegram between different german Army units, german Army command and german Army units, german Naval command and german Navy ships (especially u-Boats), german u-Boats in "wolf packs", Gestapo headquarters and Gestapo offices, some german police organizations. The german Navy and the Gestapo used specially modified Enigma machines for greater security than the standard Enigma machine used everywhere else. German High Command messages were sent using a different machine and sent by radio teletype instead of radio telegram. These machines were much heavier and less portable than Enigma machines but were much faster, so they operated from fixed locations unlike Enigma machines which often moved rapidly in combat. Messages to and from german spies did not use machine cyphers but were usually sent by radio telegram.
Their surface fleet was bottled up in port for much of the war, and their submarine wolf packs effectiveness was crippled by the breaking of the Enigma Code.

The German ENIGMA coding machine was used to communicate orders from Germany to its deployed U-boats. Early in WWII, the failure to break the ENIGMA code helped lead to significant losses in the Battle of the Atlantic. The Germans believed that the ENIGMA code was unbreakable. The first break for the Allies came when the British destroyer HMS Bulldog successfully boarded and captured an ENIGMA machine and its code books from the German U-boat U-110 in May, 1941. The capture of the ENIGMA machine significantly aided efforts by cryptoanalysts at Bletchley Park in England, where the main British code decryption efforts were being conducted. Eventually Bletchley Park was able to successfully build a computer that would decode all German Naval communications. This feat, as well as the Allies' success at keeping the knowledge from the Germans that ENIGMA had been captured and broken, led to the major downturn for German U-boats in the Atlantic. By the end of the war, German U-boat losses were 70%.
German naval ship Mühlhausen ended in 2007.
German naval ship Mühlhausen was created in 1967.
