On Nov. 5, 2018, a U.S. EP-3 Aries aircraft flying in international airspace over the Black Sea was intercepted by a Russian SU-27. This interaction was determined to be unsafe due to the SU-27 conducting a high speed pass directly in front of the mission aircraft, putting at risk the pilots and crew. The intercepting SU-27 made an additional pass, closing with the EP-3 and applying its afterburner while conducting a banking turn away. The crew of the EP-3 reported turbulence following the first interaction, and vibrations from the second. The duration of the intercept was approximately 25 minutes.

Unsafe actions‎ increase the risk of miscalculation and potential for midair collisions.
