Isn't the SU-25 [1], a close air support plane roughly equivalent in role to the A-10 [2]? The Su-37 had its first flight in early 2008 [3] about ten years after the SR-71 was retired [4]. If you mean the SU-27 that indeed flew in 1977 [5] but only has a service celling of 19km, much less than the SR-71's 26km. Above top secret has an interesting thread on how you would actually go about such an interception [6] [1] https://en.wikipedia.org/wiki/Sukhoi_Su-25 https://en.wikipedia.org/wiki/Sukhoi_Su-25 [2] https://en.wikipedia.org/wiki/Fairchild_Republic_A-10_Thunderbolt_II https://en.wikipedia.org/wiki/Fairchild_Republic_A-10_Thunde...
