Early tests
BMEWS' General Operational Requirement 156 was issued on 7 November 1957 (BMEWS was designed to go with the active portion of the WIZARD system) and on 4 February 1958; the USAF informed Air Defense Command (ADC) that BMEWS was an "all-out program" and the "system has been directed by the President, has the same national priority as the ballistic missile and satellite programs and is being placed on the Department of Defense master urgency list". By July 1958 after NORAD manning began, ADC's 1954 blockhouse for the Ent AFB command center had inadequate floor space; and Ent's "requirement for a ballistic missile defense system display facility...brought renewed action...for a new command post" (the JCS approved the nuclear bunker on 11 February 1959).
