SR-71 pilot recalls the mission where a Soviet MiG-25 Foxbat fired a missile at his Blackbird
"...What happened to the missile fired by the MiG-25? Could it have locked onto the Foxbat itself? Could the SR-71 DEF have deceived it? We’ll never know. However, we can assume that given that SR-71 had a cruise speed faster than the top speed of the MiG-25’s Acrid missiles, the Blackbird simply outran the AA-6. There was no chance a Foxbat could conduct a tail-chase interception of an SR-71 (the MiG-25 couldn’t carry out a head-on intercept of a Blackbird too: in fact, the Foxbat’s radar and fire control system was not sophisticated enough to solve the problems of a head-on intercept at closing speeds that would exceed Mach 5). ..."
