Following heightened security threats from Russia’s 2022 full-scale invasion of Ukraine, Finland’s Border Guard has decided to implement an advanced radio surveillance system to monitor electromagnetic signals near the Russian border and maritime zones. The system will be deployed on reconnaissance aircraft and ships, enabling detection and localization of radio frequency sources such as mobile phones, though it does not enable content interception or individual identification. Deployment began after official permission was granted in 2024 and will continue in stages through 2026 and 2027. Finnish officials underline the system’s role in improving threat response and rescue missions, while supplementing traditional patrolling. This measure aligns with Finland’s increased border security posture following Russian nuclear threats directed at NATO-aligned Finland and Sweden.
