These immersive experiences invite you to become “one of the crew” and re-live the history and technology of a U-boat for yourself!

Crack the Code

The Enigma code machine allowed German U-boat crews to scramble and unscramble secret messages they were sending to each other.  The Allied forces struggled for years to decode Enigma messages, but the code was nearly impossible to crack since Enigma machines could be reconfigured easily.

 Become a code-breaker on one of four interactive touch-screen stations.  Decode an “enemy” Enigma message sent by a friend in the exhibit by unlocking the correct rotor combination. (The Enigma machine contained multiple rotors, each with the alphabet on them. When a letter was input, the rotors would turn, causing a different letter to output.)  Or, select your own rotor combination and write secret coded messages to other U-505 visitors or to friends via the Internet.
