  "description": "On February 3, 2024, a Russian-made hydroacoustic sonar device used for submarine detection was found on the Curonian Spit. The Lithuanian Armed Forces identified the device as a reconnaissance asset employed to locate and track submarines using hydroacoustic sensors. The device was discovered after a civilian reported it to the Lithuanian Navy and is currently stored by the navy. Similar Russian sonar devices were previously found in 2021 near Lithuania in the Baltic Sea and near southern UK and Ireland in the Atlantic Ocean.",

  "notes": "The discovery of a Russian reconnaissance sonar on Lithuanian territory signals persistent covert maritime espionage activities in the Baltic Sea region. This finding likely reflects Russia's intent to monitor submarine movements near NATO waters, posing a strategic intelligence challenge. Analysts should monitor for follow-up Lithuanian defense responses or allied countermeasures, as well as any broader shifts in maritime surveillance tactics by Russia.",

  "summary_extended": "On February 3, 2024, Lithuanian naval forces received a report from a civilian regarding an unknown device with Russian markings found on the Curonian Spit. Naval experts identified the item as a Russian-made hydroacoustic sonar system used to detect and locate submarines via underwater acoustic sensors. The device, currently stored by the Lithuanian Navy, was not operational at the time of discovery. Lithuanian Armed Forces highlighted that similar Russian sonar systems had been found in 2021 both in the Baltic Sea near Lithuania and in the Atlantic Ocean near the southern coasts of the UK and Ireland. The find underscores ongoing Russian maritime reconnaissance and intelligence-gathering activities near NATO member states, highlighting the importance of continued vigilance and monitoring in the region.",
