Memorandum for Chairman, NFIB Working Group on Compartmentation, APEX Policy Elements, Regarding Proposed Changes to Classification and Compartmentation Regulations [open pdf - 51KB]
"One of Stansfield Turner's attempted innovations when he became Director of Central Intelligence in 1977 was to revise the codeword system that had evolved over the previous 17 years, in order to provide additional protection beyond Top Secret for information concerning overhead reconnaissance, signals intelligence, underwater reconnaissance, and other sensitive collection activities as well as intelligence reports based on the intelligence gathered. Part of the attempted innovation was the creation of an APEX control system to replace several control systems - including the BYEMAN and TALENT-KEYHOLE systems. Both the undated covering memo and dated memo envision the declassification of the terms 'National Reconnaissance Office' and 'National Reconnaissance Program,' noting that 'they fail to meet the test of classification.'"
