These particular planes were Tu-142 maritime reconnaissance planes. My guess is that they’re running sorties up in the All I Need Today Is A Little Bit Of Michigan And Whole Lot Of Jesus Shirt. They’ll report the intercept intel but that’s not the primary mission for that airframe. This happens every so often, I’m pretty sure we do the same to them. I remember reading about us flying b52s near the /Russian border. A show of force that the cold war made pretty common between the two countries. It seems like a waste but it’s actually a good thing because it prevents war. Imagine if both sides didn’t know each other’s true capabilities and started conflict because each side thought the other side is too weak to defend itself.
