The Chinese are known to have tested a weapon like this a few years ago. The resulting shrapnel was bad. It’s generally seen as a bad strategy for this sort of thing, unless the goal is to have a serious, long-term effect on space-based communications. You could shut-down satellite communications for a century without a great deal of trouble — whether intentional or not. No one wants that.
I highly doubt the Russians would go this route. It’s foolish and irresponsible.
The Russians and the US developed and launched their own versions of an Anti-Satellite Satellite that uses a Neutron Beam Weapon. The Russian one was tested over the US approximately 35 years ago. I know, I watched it. I knew an insider at NATCOMM and they watched it and tracked it. He had a tech journal that had an article about the scientist from Russia who invented the weapon and how he defected to the US and was helping us build one.
