According to the center, radars detected three air targets approaching the Russian state border over the Black Sea. The Su-27 fighter was scrambled to prevent foreign aircraft from entering Russian airspace.
The Su-27 identified the air targets as an RC-135 electronic warfare and reconnaissance aircraft and two Typhoon multipurpose fighters of the RAF.
"When approaching Russian fighters, foreign military aircraft performed a U-turn from the state border of the Russian Federation," the defense ministry said.
