International adoption of P.1154 and CL-84 descendants

What would successful P.1154 and CL-84 development do to British, Canadian, and international aviation?

Their influence would depend on whether armed forces treated them as specialist curiosities or as a new must-have capability that justified widespread adoption and imitation.

A successful aircraft does not automatically create a global design revolution. The Harrier was initially treated as a specialist sideshow, while P.1154 and CL-84 descendants might instead be recognized as essential capabilities. If governments and services chose the latter interpretation, Britain and Canada could attract many adopters and prompt competing development programs elsewhere.
