Russian for "Goodbye, Motherland!"
The Tu-95 Bear-D electronic reconnaissance plane is a huge, lumbering, unarmed, turboprop bomber conversion, whose mission (not unlike that of the EP-3 Aries) is to find and track enemy ships at sea-- for example, American carrier battle groups defended by E-2 Hawkeye and F-14 Tomcat aircraft.
At the outbreak of hostilities, the Bears would signal the position of the carrier groups to strike aircraft such as the Tu-22M Backfire and then try to stay alive as long as possible.
According to the Tom Clancy novel Red Storm Rising, the Bear crews, not expecting that last part to go very well, had a grim running joke: "We have located the enemy fleet. Dosvidanya, Rodina!"
