You mean like Nimrod? Based on a 1940s jet airliner...

We can live with one carrier, but a carrier without jets is pointless.

So now:
We're finding oil in the Falklands
We've got nothing to defend them with.

What's the betting the Argies go for attempt #2?

Well if the Argies have another go they will be up against the new Typhoon fighter/bomber squadrons that are based on the Falklands along with the several thousand army garrison - so security has been beefed up a bit since the 1980's

It's a little incongruous to call the Typhoon a fighter/bomber; it's a fighter that's been fitted with bomb hard points but it's a very imbalanced design in terms of air to ground capability. The pilot might as well be leaning over the side chucking the bombs down by hand.

The garrison is the major deterrent, along with the fact Whitehall has let it be known that there's generally at least one nuclear powered HK sub in the south atlantic most of the time. Hard to stage an amphibious invasion if half your ships have been sunk already.

As long as they have a back up plan like sell the Falklands if the Argies make a successful attack. If they do beat the existing defences then we have nothing for a few years. By which point the whole situation will look very different. That will bring down the government. The existence of the HK subs is crucial. I would rather our conventional forces be boosted at the expense of Trident.

They're only as good as their supply lines. And that far away the supply lines are stretched indeed. Unless they stock pile fuel, bombs and missles etc.

Plus you'd assume if the Argies did plan on invading, the first thing they'd do is take out the Falklands airstrip, since Typhoons don't have the Harrier's ability to use makeshift runways. A landside base, unlike a carrier, can't move out of the way to avoid attack. Although you'd assume the Falklands airstrip is pretty well protected from both air and land attack. The SAS/SBS could probably still take it out but I don't think the Argentine army has anyone that good...
