Six Russian aircraft were identified over the Baltic Sea region on 20 and 21. Source: Latvia's Air Force on the evening of Saturday, as reported by European Pravda, citing Baltic states news website Delfi Details: The Russian planes did not provide flight plans and did not switch on their transmitters.

Russian aircraft were detected flying in international airspace near the Baltic states, but had not activated their transponders.

NATO troops, vessels and aircraft took to the frigid North Atlantic Ocean last month to sharpen their skills for a potential future war at sea.

NATO jets intercepted six Russian aircraft flying over the Baltic Sea without transponders or a flight plan over the past two days, the Latvian Air Force reported late on Sept. 21.

Vice Admiral Sir Nicholas Hine, in an interview with the portal wnp.pl, highlighted the key factors in the competition between Russia and NATO in the Baltic Sea. He noted that Poland receives many goods by sea and should not give up its fleet.
