Don’t you know that worrying about Russia is “so eighties”? /sarc
We had a nuclear powered missile in the 50s.
Sounds like a reboot of the old Pegasus project. If that's the case it shouldn't be spewing any radioactive substances. It's just a heat engine. It propels itself with hot air. Of course if any of the radioactive surfaces should crack or if someone shoots the missile down, that's going to be a different story.
Putin should spend money ,any amount on his Roads ,people are stealing the manhole covers ,LOL
Not so much the exhaust, that may of may not have radioactive debris in it. The problem is the barely or totally unshielded reactor. Thing has to be light enough to fly, and being one-way, no one cares about shielding. Sucks to be the guys launching the thing..............
