Do you mean the Fitter (SU-17) or the TU-22 there is a big difference with that,a SU-17 could never go as fast as a SR-71.
I meant TU-22 Blinder. Nice catch though as SU-22 would have been the export model for the SU-17.

So I did some reading. Apparently the Free Fall bomber versions of the TU-22 were built. 10-11 based on sources. These versions were mainly used as trainers. The real ones carried a single missile

Said missile has a blast radius of 1000kt

It blew it somewhere on the swiss side, somewhere
