Commander-in-Chief of the Office of Naval Intelligence (CINCONI) was the highest position within the Office of Naval Intelligence.[1]


At some point previously, ONI was disgraced resulting in the CINCONI to resign and leading Margaret Parangosky to take the position.[citation needed] She held the position until some point around 2555, where she was replaced by her protege Serin Osman.[2]
