. t. W0 `- V3 K! WEven if no SR-71 was lost due to hostile actions during the entire Blackbird career, the Mach 3+ capable spyplane faced an adversary that could effectively intercept it: the MiG-31 Foxhound.

The SR-71 impressive mission record was reached thanks to some unique features of its airframe, such as its ability to fly at more than three and a half times the speed of sound at 88,000 feet, its small (for the time) Radar Cross Section (RCS) and its sophisticated electronic countermeasures (ECM).: E: l9 N6 ]( P5 I# P
. f' S/ [- v& e+ w) fThese flight characteristics made the Blackbird safe against any attempt of interception conducted by enemy fighters or surface-to-air missiles (SAM), during its reconnaissance missions in the Russian skies during the Cold War years., ] \% \; Q* v: E% A
) d0 D# M5 R7 c7 c; E4 KThe only aircraft which possessed the capabilities to shoot down an SR-71 was the F-14 Tomcat, that could use its AIM-54 Phoenix long range missile against the fast black plane.

9 [4 ^6 o; G. v5 C; M+ |In fact the Phoenix was developed to shoot down Soviet cruise missiles which flew at an altitude similar to the one reached by the Blackbird. Moreover with a speed between Mach 4 and Mach 5, the AIM-54 was fast enough to cause serious problems to the SR-71.

But, the capabilities featured by the Tomcat and its long range missiles, weren’t matched by any Russian interceptor, and to stop SR-71s’ overflights, the Soviets developed an aircraft which had similar characteristics to those owned by the F-14.

6 S# p8 W. F9 zAs we have recently explained, the only aircraft that had a speed close to the one of the SR-71 was the MiG-25. But even if it could fly at Mach 3.2, the Foxbat wasn’t able to sustain such speeds long enough to reach the Blackbird., F- `" [( t" f( Z

These deficiencies were settled when a more advanced MiG-25 development, the MiG-31, entered in service in the 1980s: the Foxhound was armed with a missile very similar to the US AIM-54 Phoenix, the R-33 (AA-9 Amos as reported by NATO designation).

“The scheme for intercepting the SR-71 was computed down to the last second, and the MiGs had to launch exactly 16 minutes after the initial alert. (…) They alerted us for an intercept at 11.00. They sounded the alarm with a shrill bell and then confirmed it with a loudspeaker. The appearance of an SR-71 was always accompanied by nervousness. Everyone began to talk in frenzied voices, to scurry about, and react to the situation with excessive emotion.”

Myagkiy and its Weapons System Officer (WSO) were able to achieve a SR-71 lock on at 52,000 feet and at a distance of 120 Km from the target.0 A! ~7 y) [9 U) h4 \

After this interception Blackbirds reportedly began to fly their reconnaissance missions from outside the borders of the Soviet Union.

That day, no less than six MiG-31s “intercepted” an SR-71 over the Barents Sea by performing a coordinated interception that subjected the Blackbird to a possible all angle air-to-air missiles attack.; Q8 W+ ^, z& r; z6 C

Apparently, after this interception, no SR-71 flew a reconnaissance missions over the Soviet Union and few years later the Blackbird was retired to be replaced with the satellites.
