Ultra
The British government established a code-breaking effort, known as Ultra, at Bletchley Park in Buckinghamshire, England, during World War II.
At Bletchley Park, Hut 8 was the section where Alan Turing and his team worked to break the German Enigma cipher.1
Hut 8 is specifically known for the team's success in June 1941 in breaking into the daily communications of German U-boats operating in the North Atlantic. By deciphering these messages, the team revealed the positions of the submarines, which allowed Allied ships to avoid contact and helped mitigate the severe threat posed by U-boat sinkings to Britain's supply lines.2
