In connection with the tightening of sanctions by the US and the EU, Roscosmos Corporation has serious problems in providing high-precision electronics. In particular, this is due to the restriction of access to space-based electronics.
As noted in the corporation, they were hostages of the situation. For civilian and military cosmonautics, the delivery of a whole range of necessary nomenclature of electronic products sharply limited or completely stopped access to them by the Russians.
It is noteworthy that today Russian electronics dominates in the domestic space industry. About 10 years ago, our products had a larger import electronic component base, which was especially resistant to radiation.
However, this, as it turned out, is clearly not enough. For after 2014, the United States introduced an even more stringent than before, a ban on the delivery of space and military electronics to Russia.
