The Stoiky has been encountered on several occasions during the past year as a Steregushiy-class corvette, or small warship.
The Korolev is a large amphibious landing craft.
The military vessels were seen 13 nautical miles, or about 24 kilometers off Latvian territorial waters in the country’s Exclusive Economic Zone (EEZ).
