Between the beginning of January and September 1 of this year, Russian military aircraft and ships had been detected 173 times near Latvia's border. On October 6, the NAF observed a small submarine being lifted inside a Russian support ship near Latvia's territorial waters. The Defense Ministry has no information as to whether Russia owns such submarines, and for what purposes they are used.
The Latvian Ministry of Defense reported at the end of February that Russian military flights near Latvian territorial waters had been detected frequently in recent months and their activity had been growing during the past five years.
Russian military aircraft usually operate with their automatic receivers turned off and without a flight plan, refusing to respond to civilian air traffic controllers.
