NATO jets intercepted Russian planes flying close to NATO airspace nearly 300 times in 2019, an alliance official said, amid a continuing upward trend of Russian and NATO aircraft encounters.
The official, who spoke on condition he not be named, told RFE/RL’s Bulgarian Service that Russian military aircraft activity in the Black Sea and other parts of Europe had increased since 2014.
"In 2019, allied aircraft took to skies 290 times to escort or shadow Russian military aircraft all across Europe," the official said in an e-mail on May 23.
He did not immediately respond to follow-up questions about encounters in past years.
Earlier this week, five NATO jets from three Black Sea alliance members -- Bulgaria, Romania, and Turkey -- were scrambled to respond to two Russian Tu-22 strategic bombers and two Su-27 fighter jets who approached the three countries’ shared airspace in a western part of the Black Sea.
Bulgarian military officials said the Russian aircraft returned to Russian airspace without incident.
"They do it on a regular basis," Defense Minister Krasimir Karakachanov said. "They are testing our capability and want to see how we are going to react, how fast we will send the planes and whether our radars will detect them."
In the Black Sea, in particular, there has been an uptick in Russian military activity since
2014, when Moscow seized Ukraine’s Crimean Peninsula. Since then, Russia has bolstered its military forces in the region, prompting more surveillance and monitoring from NATO’s Black Sea members.
"There has definitely been an increase since 2014. This is related to the strengthening of Russia's military presence in the Black Sea region after the annexation of Crimea," Velizar Shalamanov, a former Bulgarian military official, told RFE/RL.
