The interceptor was developed during the late 1950s and early 1960s as a potential replacement for the F-106 Delta Dart interceptor for the United States Air Force (USAF).
Before the test "Snoopy" could fly, the XF-108 program was cancelled, and the proposed Lockheed YF-12 interceptor was to instead receive the radar/missile system pair. Tests of the system were conducted first in 1960 and until 1963 only on the modified B-58, after which the YF-12 took over until the cancellation of the whole program in 1966. [1]

Thus, in 1960 the ...
