I was on the GD Aerosystems Course in 82 and, as part of Industry Engagement, we visited the Dassault facility in Bordeaux. Wandering into a hangar we discovered a row of brand new Super Etendards with Argentinian markings.
The French Government rep was a bit disconcerted when we all started posing by them for photos which conveniently captured all the tail numbers. Much Non, Non which got ignored. Never did find out if they were actually delivered.
