Signals Intelligence in Modern History - World War II

World War II

A true world war, SIGINT still tended to be separate in the various theaters. Communications security, on the part of the Allies, was more centralized. Given that there were three major Axis powers, each primarily operating in a subset of the theaters, it is convenient to look at SIGINT from a primarily theater standpoint. From the Allied perspective, the critical theater-level perspectives were the Ultra SIGINT against the Germans in the European theater (including the Battle of the Atlantic, the Mediterranean Theater of Operations, and MAGIC against the Japanese in the Pacific Theater and the China-Burma-India theater. Germany enjoyed some SIGINT success against the Allies, especially with the Merchant Code and, early in the war, reading American attaché traffic. Japan was the least effective of the major powers in SIGINT. In addition to the official Allies and Axis battle of signals, there was a growing interest in Soviet espionage communications, which continued after the war.

British strategic stations were located at places including Darwin, Australia, and a Russian site. Major postwar stations include RAF Menwith Hill and Cyprus.

Famous quotes containing the words war ii, world and/or war:

    There’s no telling what might have happened to our defense budget if Saddam Hussein hadn’t invaded Kuwait that August and set everyone gearing up for World War II½. Can we count on Saddam Hussein to come along every year and resolve our defense-policy debates? Given the history of the Middle East, it’s possible.
    —P.J. (Patrick Jake)

    I did not live until this time
    Crown’d my felicity,
    When I could say without a crime,
    I am not thine, but Thee.

    This carcase breath’d, and walkt, and slept,
    So that the World believ’d
    There was a soul the motions kept;
    But they were all deceiv’d.
    Katherine Philips (1631–1664)

    Unless they are immediate victims, the majority of mankind behaves as if war was an act of God which could not be prevented; or they behave as if war elsewhere was none of their business. It would be a bitter cosmic joke if we destroy ourselves due to atrophy of the imagination.
    Martha Gellhorn (b. 1908)
