This western aircraft was a child of the late 60s, being a twin turbofan delta fighter from a reputed manufacturer with large exports to its name.
It's initial development was in reply to requested proposals which were cancelled, the aircraft design & build then being funded by the manufacturer in response to expected export sales. For several reasons the export market never materialised, the prospective customers electing for something inferior.
Had the aircraft been brought to production, it would have been the "superior" air superiority fighter of it generation.
Its USPs were some of the construction methods used, and the control surface layout?
