According to officials, in a 90-minute encounter, the Russian SU-24 fighter jet made a dozen low passes — ranging from sea level to several thousand feet — near the USS Donald Cook.

The crew aboard the Donald Cook made several attempts to radio the Russian warplane asking the pilot what were his intentions and sending warnings to remain at a safe distance, but the Russian pilot never responded.

The Donald Cook only responded to the Russian jet with radio warnings, and “did not go to battle stations.”
