A Russian Su-27 jet performed an unsafe intercept of a US Navy surveillance plane while it was flying in international airspace over the Black Sea Monday, three defense officials told CNN.
The American pilots reported that the Russian jet came within 5 feet of the US plane, according to two of the officials.
The Russian jet’s action forced the US Navy aircraft to end its mission prematurely, one of the officials said.
The US State Department issued a statement late Monday accusing the Russians of “flagrantly violating existing agreements and international law.”
“This is but the latest example of Russian military activities disregarding international norms and agreements,” State Department spokeswoman Heather Nauert said in the statement. “We call on Russia to cease these unsafe actions that increase the risk of miscalculation, danger to aircrew on both sides, and midair collisions.”
US Naval Forces Europe, which oversees US operations in the region, provided more detail about the intercept, which it said lasted a total of two hours and 40 minutes.
“This interaction was determined to be unsafe due to the SU-27 closing to within five feet and crossing directly through the EP-3’s flight path, causing the EP-3 to fly through the SU-27’s jet wash,” US Naval Forces Europe spokesman, Capt. Pamela Kunze told CNN.
“Unsafe actions increase the risk of miscalculation and midair collisions,” Kunze said, adding, “The US aircraft was operating in accordance with international law and did not provoke this Russian activity.”
The Russian Defense Ministry said its fighter jet flew “strictly in accordance with international rules” when it intercepted the US surveillance plane.
In a statement, the Defense Ministry said that an “unidentified air target” was detected approaching Russian airspace at about midday over the neutral waters of the Black Sea.
“A Su-27 fighter was sent to intercept the target and approached the aircraft at a safe distance and identified it as an ER-3E (Aries II) US reconnaissance aircraft,” the statement said. “The crew of the fighter jet reported the identification of the American reconnaissance aircraft and accompanied it, preventing it from violating Russian airspace, observing all necessary security measures.”
“The entire flight of the Russian Su-27 was strictly in accordance with international rules for the use of airspace and there were no extraordinary events,” the statement added.
Several unsafe interactions between Russian and US military forces have taken place near the Black Sea.
Russian, US and NATO forces operate in close proximity to one another in the area, particularly since Russia boosted its military presence in the region following its annexation of Crimea in 2014.
