Argentina is a uer of the A-4 Skyhawk. I think it was in 1982 during the Falkland Island conflict where it was responsible for destroying several British ships. What ships they destroyed I cannot recall.
British ships sunk or damaged by Argentine A-4s include:
HMS Coventry - sunk
HMS Antelope - sunk
HMS Ardent - sunk
HMS Sir Galahad - sunk
HMS Argonaut - seriously damaged
HMS Sir Tristam - seriously damaged
