Can anyone verify this story about Blackbirds?

I remember reading about SR-71(Blackbird) aircraft flying in Swedish
airspace on recon missions to Russia ...

IIRC what I read on "Black Jets" (Airtime Publishing), though built
for that purpose, the Blackbirds were never sent on recon missions
over russian territory. One of the reasons why the A-12's were built
was the fact that in the late 50's the Agency envisaged that the U2
would soon be vulnerable to russian SAMs, as Gary Powers would later
demonstrate over Russia in 1960 and Rudolph Anderson over Cuba in
1962. Seems like the political sensitiveness caused by the Gary Powers
shootdown made the US keep the Blackbirds out of "russkie" skies.
