Russia has developed a surveillance system for nuclear submarines in the Arctic, using equipment purchased through front companies, including from the USA and Europe.

Russia is protecting its nuclear submarine fleet in the Arctic through an advanced surveillance system called 'Harmony', built with high-tech equipment acquired from American and European companies. These acquisitions were made through a secret network of front companies, such as Mostrello Commercial Ltd., which served as an intermediary for obtaining military technology. The Harmony system includes underwater sensors and drones capable of operating at great depths, serving to detect American submarines and ensuring Russia's ability to launch nuclear attacks in the event of conflict.

Recent revelations, part of an investigative project, show how Russia has managed to circumvent Western sanctions, thereby strengthening its nuclear strategy. Experts emphasize that these measures undermine the security of the United States and NATO allies, allowing Russia to operate without being detected. Additionally, court documents and financial records suggest that Russia has used legitimate companies in Europe as contact points to mask the end use of the equipment. This complex procurement network has been monitored by American and allied intelligence services, but specific details remain largely classified.
