Russia appears to have suffered a “catastrophic failure” in a test of its Sarmat missile, a key weapon in the modernization of its nuclear arsenal, according to arms experts who have analyzed satellite images of the launch site.

I would like to thank [OSINT analyst] MT_Anderson for providing this image from Planet Labs and allowing me to publish it with comments. As can be easily seen, the RS-28 Sarmat test ended in complete failure,

Late last week, Russia's military planned to launch a Sarmat intercontinental ballistic missile (ICBM) on a test flight from the Plesetsk Cosmodrome. Imagery captured over the weekend from commercial satellites suggests the missile exploded before or during launch.
