‘Y’ service

The Oxford Companion to World War II | 2001 | 590 words | Copyright

‘Y’ service was the British codename for the interception of enemy radio and telephone traffic. ‘Y’ service detachments formed part of the signals branch of each of the three armed services and were treated, like cipher staff, with special secrecy. All the principal warring powers, and the Poles, had similar detachments, listening to what their enemies were saying among themselves. Their results were divided into traffic analysis, location (see huff-duff), normal intelligence analysis, and decipher. See also signals intelligence warfare.
