Operation Ultra

Operation Ultra was a series of secret Allied military efforts during World War II focused on intercepting and decoding German communications, particularly those encrypted with the Enigma machine. The goal was to gain intelligence on German military plans, movements, and operations. By breaking the codes, Allied forces could anticipate enemy actions and make strategic decisions, significantly contributing to the war's outcome. Ultra represented one of the earliest and most successful examples of signals intelligence, profoundly impacting warfare by turning intercepted communications into actionable intelligence while keeping the effort covert.
