of course they did Cosmicomet, it would not have been within the spirit of war had they been bought in on that ship now would it? 
I notice by your age by the way that you were only 8 years old at the time so your information is clearly from other sources. I am going on what my Dad (and plenty of others) witnessed right in front of us.
As for the history prior to 1982 that is for another thread elsewhere and not for getting in the way of the real topic of this thread.
Dear VP, I don't know what your father or friends so back in 1982 but it wasn't a MM38 launcher off loaded from the ARA Almirante Irizar.
According to the real story, the MM38 luancher and guidance system was loaded in two C-130H from Espora (South East Buenos Aires) to Comodoro Rivadavia Airport and from there to Puerto Argentino airport.
If you have some Spanish language knowledge you can read a full article written by the one of the Navy Officers in charge of the developement of the SM38 Exocet.
