Royal Navy patrol ship HMS Severn intercepted and shadowed Russian intelligence vessel Viktor Leonov as it monitored NATO’s Joint Warrior 24-2/Nordic Response 24 exercises off Scotland’s east coast in the North Sea from late Sept. to early Oct. 2024, with the Russian ship gathering signals intelligence on alliance forces from nearby international waters.

Summary

The UK Royal Navy intercepted a Russian intelligence-gathering vessel, the ship Viktor Leonov, as it was closely monitoring NATO military exercises off the east coast of Scotland in the North Sea. The incident occurred during NATO’s large-scale joint exercises Joint Warrior 24-2 and Nordic Response 24, held off the Scottish coast from Sept. 29 to Oct. 8, 2024. According to the Kyiv Independent report, the Viktor Leonov was observed near British territorial waters as Royal Navy patrol ship HMS Severn shadowed and monitored its movements and activities. The article states that the Russian ship’s mission was to gather signals and electronic intelligence on NATO ships and aircraft participating in the drills, including information on their communications, radar emissions, weapon systems, and operational tactics. The UK Defence Ministry confirmed that the Royal Navy maintained a persistent escort and surveillance posture to ensure the safety of the exercise and the integrity of UK and allied operations. The Russian vessel did not enter UK territorial waters but remained in the surrounding international waters of the North Sea. The report notes that Russian spy ships have previously appeared near NATO exercises and critical undersea infrastructure, and that Western officials see these deployments as part of Russia’s broader hybrid toolkit aimed at intelligence collection and potential mapping of vulnerabilities in alliance maritime infrastructure. The article highlights that the interception underscores ongoing Russian efforts to monitor and probe NATO activities in the North Atlantic and European theaters amid heightened tensions over Russia’s war against Ukraine.

Classification

Confidence: Medium

The core activity is a Russian intelligence-gathering vessel monitoring NATO exercises from nearby international waters, which constitutes a hostile intelligence operation within a hybrid-warfare context rather than routine defense preparation by NATO. While the UK Navy response is defensive, the primary focus of the report is the Russian collection effort and its role in probing NATO capabilities.
