Editing Ultra (cryptography) (section)

==Postwar consequences==
The mystery surrounding the discovery of the sunk {{GS|U-869}} off the coast of [[New Jersey]] by divers [[Richie Kohler]] and [[John Chatterton]] was unravelled in part through the analysis of Ultra intercepts, which demonstrated that, although ''U-869'' had been ordered by U-boat Command to change course and proceed to North Africa, near Rabat, the submarine had missed the messages changing her assignment and had continued to the eastern coast of the U.S., her original destination.

In 1953, the CIA's [[Project ARTICHOKE]], a series of experiments on human subjects to develop drugs for use in interrogations, was renamed [[Project MKUltra]]. MK was the CIA's designation for its Technical Services Division and Ultra was in reference to the Ultra project.<ref>{{cite book |last1=Fee |first1=Christopher R. |last2=Webb |first2=Jeffrey B. |title=Conspiracies and Conspiracy Theories in American History |date=2019 |publisher=ABC-CLIO |location=Santa Barbara, California |isbn=9781440858116 |page=200}}</ref><ref>{{cite book |last1=Brown |first1=Brian |title=Someone Is Out to Get Us: A Not So Brief History of Cold War Paranoia and Madness |date=2019 |publisher=Twelve |location=New York |isbn=9781538728031 |page=264 |edition=1st}}</ref>
