Ultra
The British government established a code-breaking effort, known as Ultra, at Bletchley Park in Buckinghamshire, England, during World War II.
The Bombe machines at Bletchley Park were operated by hundreds of Wrens, who were members of the Women’s Royal Naval Service (WRNS). These operators worked long, demanding shifts in dark and stuffy rooms to help the Allies decipher Enigma-encrypted messages as part of the Ultra intelligence project.12
