Russia's having problems with its newest ICBM. It drove away critical Ukrainian missile expertise.

Russia's RS-28 Sarmat ICBM seemed to have suffered a catastrophic failure during a September test, appearing to have blown up. Satellite pictures showed a massive crater around the launchpad at the Plesetsk Cosmodrome, a spaceport in northwestern Russia. That apparent failure followed what missile experts said were multiple other problems. The powerful missile's ejection tests and its flight testing have both been repeatedly delayed, and it previously had at least two canceled flight tests and at least one other flight test failure, according to the Royal United Services Institute think tank in London.
