That kind of stuff happens all the time. And its by a lot of nations, not just Russia. Heck we do it too. Remember just a few years ago we flew a P-3 Orion too close to China. I'm just surprised the Navy still flies the F/A-18A model
Nothing like flying outdated airframes when they've spent billions on hmmm the C model, and the E model. You know, over the last forty years since the A model was released lol
