The aggressive maneuvers by Russian aircraft occurred both Monday and Tuesday. A
Navy press release states that the events began after the USS
Donald Cook left the Polish port of Gdynia on Monday. That afternoon a Polish helicopter was training with the destroyer when an Su-24 showed up.
The jet would perform no less than 20 passes near the ship. This caused the USS
Donald Cook to end flight operations.
The next day the
Donald Cook was approached by a Ka-27 Helix helicopter which made seven flights over the ship, taking photographs while doing so. Not long after Su-24s arrived on the scene and began their simulated attacks, making 11 runs in all.
The Russian aircraft were radioed throughout their time near the
Donald Cookin both Russian and English. There was no response.
