"Kinzhal" hypersonic aviation-missile complex

Yeah, I've no doubt that Su-34 can carry Kinzhal if the necessary modifications are made, but as the Su-34 lacks the operating ceiling and max speed of the MiG-31K the missiles will have a reduced range. Basic physics, nothing contraversial as far I can see.

Naaah, to complicated.
What's the difference, if it flies 2000 or 1700 km, a whole 404 is in range anyway

I know not many, if any now use the Mig-25, but Algeria just very recently retired theirs. Russian doesn't seem to be wanting to sell Mig-31, I would have thought it wouldnt have been hard to convert those Mig-25 to carry Kinzhal, the Mig-25 is still capable aircraft and for that role would still give it a use. And the upgrade I would imagine wouldn't cost much. This would give Algeria an additional punch in it's arsenal. Syria also fielded the Mig-25. Although fielding a squadron of Mig-25 carrying Kinzhal near the Med, and close to Israel probably wouldn't go down too well with Turkey, Israel and USA or maybe Russia could take out of storage some Mig-25 convert them to carry it and gift to Iran to threaten the Hormuz strait
