SEVERODVINSK, Russia — Russia has stripped long-range S-300 and S-400 air defense systems from the Sevmash shipyard. Satellite images analyzed by the Barents Observer confirm the withdrawal from three key positions: Yagry North, Yagry Central, and Mironov Hill.
The shipyard is Russia’s only facility for constructing and overhauling nuclear submarines. This includes the Borei and Yasen classes. The removal leaves the site exposed.
Imagery from July 2026 shows empty launcher pads. Radar units are missing. The systems were likely redeployed to Ukraine, a move that prioritizes front-line troops over homeland defense of a strategic asset.
The Sevmash shipyard now lacks both S-300 and S-400 coverage. Ukrainian drones or cruise missiles could potentially reach it. The vulnerability undermines Russia’s naval deterrence posture, as the facility is critical for building its most advanced submarines.
Militarnyi notes the withdrawal affects supporting facilities under the same air defense umbrella. The broader nuclear submarine industrial base is now at risk. Ongoing construction projects may face delays due to heightened security fears.
Key pain points for Russian planners include Ukraine’s increasing long-range strike capability. The loss of deterrence credibility is significant. Production delays are likely. The move signals to NATO that Russia’s defensive resources are stretched thin.
Russia may deploy short-range Pantsir systems or decoys as a countermeasure. The gap in coverage is a potential opportunity for Ukraine to exploit through direct strikes or psychological operations.
The withdrawal marks a shift in Russia’s defensive calculus. A crown jewel of its navy is now at unprecedented risk.
