A fourth YF-12 aircraft, the "YF-12C", was actually the second SR-71A (AF Ser. No. 61–7951). This SR-71A was re-designated as a YF-12C and given the fictitious Air Force Serial Number 60-6937 from an A-12 to maintain SR-71 secrecy. The aircraft was loaned to NASA for propulsion testing after the loss of YF-12A (AF Ser. No. 60–6936) in 1971.

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.
