The Latvian armed forces claim they have detected two Russian Kilo-class submarines and a research vessel 27 and 30 nautical miles outside the country’s territorial waters, three days after a sighting of a Russian destroyer was reported off its coast.
The Kilo-class vessels, to use their NATO classification, have been deployed by the Soviet, and then the Russian navy since the early 1980s. Nimble and quiet, they have traditionally been named “black holes” for their stealth capabilities.
While moving in Latvia’s exclusive economic zone, but not its territorial waters, does not contravene international regulations, the authorities in the Baltic state have expressed alarm at increasingly frequent muscle-flexing displays on its borders.
Last year, Riga alleged that Russian vessels were spotted 50 times off the coast of Latvia, and planes flew around its airspace 200 times. At no point did they violate Latvian borders, but the three Baltic states scrambled their jets 112 times last year, to escort Russian planes out of their territory.
