This aircraft, first deployed during the soviet era, caused quite a stir in the west. Back then no one knew what it was, most thought that it was a very advanced aircraft that would pose a direct threat to the west. It turns out to be a supersonic interceptor meant to tackle an incoming ICBM (back then a multi-warhead ICBM was not yet deployed so it is easier to intercept with an aircraft). It is capable of flying high and fast, so while it is mostly incomparable to modern fighter jets, it is still a highly valued piece of aircraft and still quite useful for reconnaissance and training.
