The Tu-142 is a special Tu-95 variant originally designed originally for very long range anti-submarine warfare but later upgraded to be a very sophisticated electronics intelligence/signals intelligence (ELINT/SIGINT) platform akin to certain RC-135 versions flown by the USAF. As such, these planes are often seen flying off the coast of Alaska and off the coast of Norway down to the North Sea.
CBC News identified the Bear bombers as two TU-95 bombers. It’s unknown whether or not they took note of such differences.
And no doubt heard long before being seen.
