Two Russian Su-24 aircraft make several passes by U.S. Navy destroyer Ross a few hours after the ship set sail from Odesa, Ukraine, on June 30, 2021. Ross was operating in the Black Sea alongside four other ships from Ukraine and NATO allies as part of the Sea Breeze 21 exercise. The two aircraft made several passes that afternoon but never came within a few miles of the ship, with Ross leadership saying the encounters were safe and professional. Later in the exercise, other aircraft flew close enough to appear on the ship's radar but did not come within visual distance. (Megan Eckstein/Staff)The head of the U.S. Navy destroyer Ross, Cmdr.
