But the Argies had significantly more than 5 exocets, the French may have put an embargo on further deliveries from France to Argentina hence they were being delivered, during the conflict, from France to S.Africa where they were loaded on to an AOM DC8 and flown from S.Africa to Argentina, this Minerve DC8 F-GDJM:
I have been on that DC8, many times, and in the fuselage there was a specific electrical installation where, previously, a fan had been fitted to keep the exocets cool during their journey.
And just found this on the internet, the Argies had:
six destroyers and three frigates, all Exocet-armed
four operational Super Etendard strike fighters and their air-launched version of Exocet,
