ADC's Consolidated Command. Control and Communications Program, FY 1965–1972 was an outgrowth of a 196x "ADC-NORAD PAGE Study" for replacing SAGE/BUIC with a Primary Automated Ground Environment (PAGE) . The program with a Joint DOD/FAA National Airspace System (NAS) resulted with DOD/FAA agreements for a common aircraft surveillance system, with the FAA "to automate its new National Airspace System (NAS) centers". ADC estimated its portion "would cost about $6 million, with annual operating, maintenance, and communication costs about $3.5 million" ("the first BUIC III was set to begin in April 1967 at Z-50, Saratoga Springs".)
