Although RS-26 Rubezh can be used to deliver a thermonuclear warhead or an Avangard hypersonic glide vehicle, Thursday morning's attack on the Dnipro region was non-nuclear, instead some sort of conventional warhead.
"Using these kinds of missiles, whether RS-26 or a true ICBM, in a conventional role does not make a lot of sense because of their relatively low accuracy and high cost," Pavel Podvig, a senior researcher at the United Nations Institute for Disarmament Research, wrote on X.
"But this kind of a strike might have a value as a signal," Podvig added.
