Earlier this week a Russian Su-27 Flanker made what DOD officials described as an "unsafe and unprofessional" pass on U.S. Navy P-8A Poseidon. The Russian fighter came within ten feet of the American maritime patrol jet, which was operating over international waters in the Black Sea.
The incident is the latest involving American surveillance or maritime patrol aircraft. Earlier this year, an RC-135U Combat Sent surveillance aircraft also had a close encounter with a Russian Flanker. Russian Su-24 Fencers have buzzed American and Canadian ships in the Black Sea and Baltic Sea since 2014, the year that Russia annexed the Crimean Peninsula.
"These actions have the potential to unnecessarily escalate tensions between countries, and could result in a miscalculation or accident which results in serious injury or death," the Pentagon said in a statement released Wednesday.
The Russians aren't alone with these types of acts. In 2014 and 2015, the Pentagon reported on incidents involving Chinese fighters also acting in an unsafe manner while intercepting P-8 and RC-135 aircraft over the South China Sea.
And in 2001, a People's Liberation Army Navy J-8 Finback piloted by Wang Wei collided with a U.S. Navy EP-3E Aries II surveillance aircraft. The J-8 crashed, killing Wei, while the EP-3E made an emergency landing on Hainan Island, where the crew was held for over a week.
