Current existence and manufacturers support.
Who, exactly, would you suggest is willing to ramp up and produce a "cheap" Buccaneer with practically zero profit margin, no R&D spin-off and no export sales?
BWoS wouldn't touch it - perhaps there are a few OAPs who worked at Blackburn still alive and compos mentis? Build a factory, train a staff, build 3-4 sqns of cheap aircraft - then shut it all down again - deep joy........
