U.S. Navy video shows a flight of two Russian Sukhoi Su-24 Fencer strike aircraft buzzing the guided missile destroyer USS Donald Cook (DDG 75) in the Baltic Sea. The aggressive low-level flying mimicked strafing runs, and was protested as dangerous and unprofessional by U.S. Secretary of State John Kerry. The more provocative passes crossed the destroyer’s flight deck, coming within a reported 75 feet of the ship. The two aircraft appeared to be lacking external stores other than drop tanks in photos that accompanied the U.S. Navy video releases, but Fencers typically carry an internal 23mm cannon.
