Yf-12a Performance in F-108 Category
Los Angeles—Performance envelope of the Lockheed YF-12A prototype interceptor (AW&ST Oct. 5, p. 16) is an improvement but nevertheless in the same category as that projected for the North American F-108 long-range interceptor. F-108 development was canceled by Defense Dept, in September, 1959, because advanced interceptors were considered by the Eisenhower Administration as not vital to future national defense of the country at that time.
