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.

President Vladimir Putin said Friday that Russia will continue to test and start mass-producing the hypersonic ballistic missile that it fired at Ukraine Thursday.

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

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,

Russia's attack on Ukraine that used an "experimental" intermediate-range ballistic missile dubbed Oreshnik was messaging, not mass destruction. Why it matters: The Nov. 21 salvo underscored how little recourse Moscow has to Western aid — like Army Tactical Missile Systems — once deemed red lines.

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

Hypersonic weapons like Russia’s Oreshnik missile present a formidable challenge to existing missile defense systems. However, defenses capable of intercepting them do exist.

The Washington Post reported that U.S. officials are quietly acknowledging that Ukraine may soon have no choice but to negotiate with Russia, potentially sacrificing territory it considers its own. As Russian forces continue to reclaim land,

Russia has launched its largest drone offensive on Ukraine since the conflict began, deploying at least 188 drones that struck residential areas in Kyiv and caused power outages across the country. Moscow continues to intensify its efforts on Ukraine’s eastern front while promising "retaliation" after Ukrainian forces once again used U.

Days after staging their largest ever drone attack on Kyiv, Russia has closed airspace for three days around a testing site for its ‘unstoppable’ hypersonic ballistic Oreshnik missile. Moscow issued a notice to airmen and shut the airspace ‘from ground level to unlimited altitude’ from 4am today until 8pm on November 30.
