On May 28, 2025, an unprecedented intelligence failure by Russia was revealed when over two million classified documents detailing Russia's strategic nuclear infrastructure at the Avangard hypersonic missile base in Yasny leaked via Russia's own government procurement portal. Defense contractors responsible for infrastructure upgrades inadvertently exposed detailed blueprints, network diagrams, and sensitive security architecture files which were accessible for months. This breach exposes critical vulnerabilities of the Avangard program—a cornerstone of Russia's nuclear deterrence—potentially forcing Russia to abandon or extensively redesign parts of its nuclear infrastructure at immense financial cost, estimated over $2 billion. The leak also revealed Western materials within Russian military projects, highlighting sanctions-evasion supply chains. Inside Russia, FSB inquiries and emergency audits are ongoing, signaling severe internal fallout. The Russian Ministry of Defense has not commented publicly, but intelligence analysts recognize the strategic impact as historic. The leak compromises Russia's nuclear deterrence by exposing operational and security details to adversarial intelligence services, posing grave strategic and security consequences.
