According to the Ukrainian military, the intelligence haul includes the combat structure of the submarine, its technical constraints, and the regulatory documents that govern its daily operations. The information reportedly allows Kyiv to map the full strategic and engineering profile of the Borei-A class submarine. While no details were given on how the intelligence was acquired, officials stressed its potential value for Ukraine’s naval defense and broader intelligence efforts.

Ukraine emphasized that the intelligence would be useful in evaluating both individual assets and the overarching capabilities of Russia’s strategic nuclear fleet. The GUR described the breakthrough as a major achievement in the ongoing war effort, particularly in tracking and countering Russian sea-based deterrents.

The Knyaz Pozharsky was unveiled at a naval ceremony attended by President Vladimir Putin, underlining Russia’s continued investment in nuclear deterrence amid its war in Ukraine. The Borei-A class submarine is part of Russia’s long-term military modernization program, designed to enhance second-strike capability and strategic reach.

Ukrainian officials did not disclose whether allied partners assisted in the intelligence operation. However, the timing of the announcement suggests a deliberate move to demonstrate Ukraine’s capabilities in penetrating Russian military secrecy as the war enters a new phase of attrition and strategic messaging.
