That whole maneuvering thing can indeed be tough. I remember the Russians shooting 5 cruise missiles from the Caspian to Syria and timing them by route turns to land at the same time. Easier at the slower speeds. Then I remember guys telling me that it takes a Blackbird about 180 miles to make a 180 degree turn, at speed. If one is going to fly hypersonic then making any kind of turn is going to be a neat trick. Try, just for fun, figgering out how you would turn a big rifle bullet?
Most of us came to that conclusion decades ago. You wouldn’t do much turning streaking across the sky like a meteor.
You program tgt coordinates and during mid-phase make adjustments for attack axis and avoid overflight or select countries. All the maneuvering at the top speed takes place far, far from the target and at altitude, and when it begins its decent, its fins adjust and refine the attack axis.
