I'm sure that replacing the old analogue servos in the Buccaneer bombing computer which, once the accept bar had been squeezed, all voted on when to release the weapon, was probably a good thing, given the computing power of digital avionics. Tornado ground mapping radar is probably rather easier to use than the Blue Parrot radar in the Bucc was as well.
As for airframes?
Improved Buccaneer with updated avionics and radar - now, that would have been interesting!
