The Pentagon says the Oreshnik is a tweak of Russia’s RS-26 Rubezh missile, an intercontinental ballistic missile (ICBM) that has been tested since 2011.

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.

A new intermediate-range ballistic missile called Oreshnik used by Russia in a strike on Ukraine this month is a state-of-the art weapon that the West cannot intercept, President Vladimir Putin has said.

Russia fired a hypersonic intermediate-range ballistic missile at the Ukrainian city of Dnipro on Thursday in response to the U.S. and UK's allowing Kyiv to strike Russian territory with advanced Western weapons,

Russian President Vladimir Putin said in a televised address that the attack was a test of Russia's "newest missile," an IRBM called "Oreshnik."

Ukraine's Foreign Minister Andrii Sybiha has announced that the Russian attack on the city of Dnipro with an Oreshnik experimental ballistic missile will be discussed at the Organisation for Security and Cooperation in Europe on Wednesday,

The new design is based on the previous RS-26 Rubezh ballistic missile, according to the Pentagon. Readers can get up to speed on what else is already known about the missile strike on the eastern Ukrainian city of Dnipro in The War Zone‘s initial reporting here.

The first combat use of Russia’s new IRBM — which Russian President Vladimir Putin called unstoppable — has drawn scrutiny from Western military experts.

Russia’s new ballistic missile flies on a high arc out of Earth’s atmosphere and releases multiple high-speed projectiles, making it challenging but not impossible to intercept

Vladimir Putin is threatening to launch a new intercontinental ballistic missile, which he calls "Oreshnik," against Ukraine, with Kyiv potentially being the target, the Russian media Kommersant reports.
