Overview

• Ukrainian military intelligence claims it extracted battle plans, technical blueprints and crew lists from the Knyaz Poscharskiy during a secret Arctic operation.
• Kyiv asserts that the stolen files reveal vulnerabilities across all Project 955A Borei-A submarines and could undermine Russia’s second-strike capability.
• The operation, codenamed “Spinnennetz,” underscores Ukraine’s growing reliance on cyber warfare to offset conventional disadvantages.
• Moscow has not publicly addressed the allegations and there is no independent confirmation of the hack.
• The breach raises the stakes in the Arctic, where expanding U.S. and Chinese naval activity complicates Russia’s strategic ambitions.
