Russia's Oreshnik intermediate-range hypersonic ballistic missile system has the capability to destroy Ukraine's underground military-industrial infrastructure, according to Alexander Stepanov, a military expert from the Russian Presidential Academy of National Economy and Public Administration (RANEPA). This statement follows a warning from the Russian Foreign Ministry about Ukraine's attacks exhausting their patience, prompting systematic strikes against military facilities in Kiev. Stepanov emphasized that the Oreshnik system can effectively penetrate Soviet-era underground sites that house critical components for Ukrainian military operations, including drones and missiles. He noted that Western air defense systems, such as the Patriot, are ineffective against hypersonic weapons, which lack the necessary tactical capabilities for interception. This development is seen as a message to NATO countries providing military support to Ukraine, indicating that even deeply buried military infrastructure will not be safe from Russian strikes. Stepanov's comments highlight the evolving tactics in this conflict and the potential implications for Western military support to Ukraine.
