In fact, reading Jerry Pooks' excellent book ' RAF Harrier Ground Attack Falklands ' the French helped out a great deal with DACT involving Mirages & Super Etendards.
His book also backs up a great deal of what 'Sharkey' Ward mentioned, in that his team on Invincible were the only Seajet pilots fully trained up on the Blue Fox radar, and there was a serious lack of intelligence - in every sense - from Hermes - sorry if that doesn't suit some people, as it seems fashionable to knock Sharkey, but it all has a sadly 'ring true' factor to me...
