Why does the Tu-22M3 nose have this peculiar shape?
Nobody knows why except Andrei Nikolayevich Tupolev, and he is dead.

Andrei Tupolev was known to insist on the fast and adequate at the expense of the theoretically correct, leading to widespread technical debt in his designs. He may have raised the nose cone for no more profound reason than to get the refueling probe in line with the pilot's vision. Once he had energetically dictated where the probe was to go, no one at the design bureau would dare suggest moving it; they would just work the forward avionics into the resulting odd shape as best they could.

Tupolev died in 1972 leaving this and many other of his decisions unexplained.
