Perhaps you're thinking of the Bombe.
I believe crew members off a British destroyer that had disabled a German submarine during WW2. The German crew was kept in isolation to insure the Germans did not learn that an enigma code machine had been captured by the British..........
The British at Bletchley Park broke the codes used by the German encryption machine known as "Enigma".
Turing did not work on the Enigma, it was a German machine. However he did do some work on the British Bombe machines that were used to crack the Enigma machine cipher. Later he saw Tommy Flowers' Colossus electronic computer, designed to crack the German Lorenz SZ40/42 machine cipher. This inspired him after the end of the war to begin work on programmable electronic computers.
The Enigma was used to decode the Enigma. The British decoders at Bletchley Park during the Second World War used brain-power to try to crack the German codes. That is, until they got their hands on an Enigma machine which the Polish had captured.
It was called The Enigma Machine for German encoding.

I don't know what the Germans called it, but when the British got ahold of it and began trying to decrypt it, they called it the "Enigma machine".
enigma was the German code making machine not code breaking ultra was the code breaking machine
The Allies became aware of the Enigma machine through various intelligence efforts, including the work of Polish cryptanalysts in the early 1930s who first broke its codes. After the German invasion of Poland in 1939, the Polish intelligence shared their findings and the machine itself with British and French officials. This collaboration laid the groundwork for the British codebreakers at Bletchley Park, who further developed techniques to decipher Enigma-encrypted communications throughout World War II.
It was called the Enigma.
Polish cryptanalysts working in Warsaw, Poland first broke the German Army Enigma and built a simple electromechanical Bombe machine in spring of 1939. However when the Germans invaded on September 1, 1939 they had to flee Poland. Initially going to France, but when France was invaded in 1940 the Polish cryptanalysts went to England. There they became part of the team at Bletchley Park. The British team at Bletchley Park had been stymied by Enigma until the Poles arrived, bringing with them a stolen German Army Enigma machine (which answered several questions the British had). Bletchley Park eventually designed larger more advanced and powerful Bombe machines which they used throughout the war to read Enigma messages. Several times the Germans made improvements to the Enigma (especially the Navy Enigma) forcing the British to have to break the cypher again, sometimes even involving capturing another Enigma machine to see what those changes were. The most difficult change to break was the addition of a 4th rotor to the Navy Enigma, which could only be handled by the addition of a high speed vacuum tube electronic box to the side of the electromechanical Bombe machine.
