Russia named the missile the Oreshnik, or hazel tree, and said it is impossible to intercept it with air defenses.

This is the first time Russia has used its so-called Oreshnik intermediate-range ballistic missile in combat. The launch also serves as a warning to the West.

Russian President Vladimir Putin confirmed Podvig’s assertion Thursday afternoon, when he announced the weapon that struck Dnipro was an experimental medium-range ballistic missile called “Oreshnik.” MRBMs typically travel no farther than 600 miles.
