Underwater archeologists sponsored by the World Wide Fund for Nature (WWF) have found an Enigma machine at the bottom of the Baltic Sea, likely from a submarine that Germany scuttled at the end of World War II. Enigma machines, created in Nazi Germany in the 1930s and 1940s, were used to encode military messages; these codes were finally broken by the experts assembled by the British at Bletchley Park, work which fueled the creation of modern computers. Earlier this year, a four-rotor M4 Enigma cipher machine sold at an auction for £347,250 ($437,955). "We suspect that our Enigma went overboard in the course of this event," says Florian Huber, underwater archaeologist and diver in the Submaris team, which found the encryption machine. They were deployed to Germany's U-boat fleet in 1941 and prevented the Allies from knowing where German's U-boats were positioned for almost a year until English mathematician Alan Turing and, separately, Joe Desch in Dayton, Ohio developed the computer that broke M4 encryption to decipher German messages.
The WWF-sponsored diving crew who found this Enigma machine were exploring because abandoned fishing nets kill marine mammals, fish and sea birds. The dive team found the Enigma machine this November at the bottom of Gelting Bay in the Baltic Sea. "The WWF has been working for many years to rid the Baltic Sea of dangerous ghost nets. WWF Germany launched the ghost net project in 2016 to remove abandoned fishing gear from the Baltic Sea. It estimated there were 800 tonnes of old nets, which keep on catching fish after they're abandoned. Underwater archaeologist Florian Huber told Reuters he thought they had discovered a typewriter entangled in a net But I never dreamt that we would one day find one of the legendary Enigma machines," said Huber.
The divers said that even though Enigma machines can sell for tens of thousands of dollars at auction, theirs will be donated to the Archaeological Museum Schloss Gottorf in Schleswig, Germany.

The device, famously used by Nazis to encrypt messages during the Second World War, was uncovered by a group not normally associated with marine archaeology: the World Wildlife Federation (WWF). After the discovery, one of Huber's colleagues "swam up and said: there's a net there with an old typewriter in it," he told the DPA news agency. On Friday, the group handed the Enigma machine over to a German museum for restoration.
"A colleague swam up and said: [T]here's a net there with an old typewriter in it," lead diver Florian Huber tells the DPA news agency. As Agence France-Presse reports, the group's find is a rare Enigma cipher machine used by Nazi Germany to transmit encrypted military communications during World War II. The divers found the machine off the coast of northeast Germany in the Bay of Gelting, which is part of the Baltic Sea. On assignment for the World Wildlife Foundation (WWF), the team had been using sonar technology to scan for "ghost nets," or abandoned fishing nets that pollute the oceans and pose a deadly threat to fish, seabirds and other marine mammals, per a statement. The machine discovered by the divers had three rotors, so it likely came from a German warship. U-boats—powerful submarines that wreaked havoc on Allied forces during the first and second world wars—usually carried more complex four-rotor Engima devices, historian Jann Witt of the German Naval Association tells the DPA. Though Enigma machines did, for a time, allow German forces to secretly communicate troops' positions and plans of attack with impunity, the Allies eventually cracked their code. The Polish codebreakers' efforts paved the way for subsequent research ventures, including British mathematician Alan Turing's Bletchley Park team, which eventually cracked the increasingly sophisticated Enigma encryption.
