The navy released a video showing the Su-27 turn sharply in front of the surveillance plane with its engines firing. And in June a year ago, an Su-27 closed in on the wing of a U.S. RC-135U reconnaissance aircraft over the Baltic Sea at high speed, U.S. European Command said at the time.
A Russian Su-27 fighter jet intercepted a U.S. Navy reconnaissance plane Monday over the Black Sea, but the incident was resolved without any hostilities.
Eric Pahon, a Pentagon spokesman said that what made the intercept was unsafe was that "they didn't establish radio contact, they came really really close to our aircraft".
'The Su-27 jet's crew reported identifying the #US EP-3 Aries spy plane and accompanied it, preventing a violation of Russian airspace and followed all necessary safety procedures, ' the tweet said.
The statement from the Navy added that the EP-3 was operating within global law and did not provoke the Russian jet.
"There's just absolutely no reason for this type of behavior", said Pahon, who noted that the American aircraft was flying a routine mission in global airspace "and the Russian aircraft kind of came out of nowhere and did not one, but two passes close to our aircraft". "The crew of the EP-3 reported turbulence following the first interaction, and vibrations from the second", according to a statement from the US Navy.More news: Tragedy at Melbourne Cup as horse The CliffsofMoher put down after injury

Though the USA has announced its Trident Juncture military exercises in global airspace and waters, or over friendly countries with their approval, Russia's military has made a number of "surprise visits", most recently with a long-range bomber flying over a United States warship.
Also on Monday, a Pentagon spokesperson said that the Russian jet came "very, very close" to the U.S. EP-3 aircraft, adding that it made an additional pass after activating its afterburners to create more turbulence.
After resolving the issue "in a safe manner", the Su-27 returned to its base.
"There's just absolutely no reason for this type of behavior", he said.
At least six US Air Force spy planes conducted a number of flights along Russia's borders on November 5.
