Do the Argentinian's still have a serviceable aircraft carrier by the way?
Although the Argentine carrier
Veinticinco de Mayo was retired in 1997, the naval air forces of Argentina do still maintain at least a basic level of shipborne operating skills, through co-operation with the Brazilian navy.....
...and with the USN. Although with the USN, operations are limited to practice approaches and touch-and-go landings only.
Whereas the UK has no fixed wing assets capable of shipborne operation and is unlikely to have any organic naval air power for a decade - unless things change pretty dramatically. But I doubt whether Argentine interest in the Islas Malvinas will be the catalyst.
