In contrast, last year, I believe the Argentine Navy had something like 260 sailing days - between their entire force! One solitary capital ship in the RN spent more days out in the water than the entire Argentine navy..dearie me..
We could actually put a task force of some sort together and retake the islands, it'd just be a lot different and you'd have a bit more tap dancing to do in logistics.
If you were really getting Tom Clancy, get the Navy down there, throw a defensive bubble around a space, lay down a very rapidly constructed runway and then break out the surface to air batteries, you've got your air head, the rest comes down by air. White knuckle stuff but doable..
Three T45's could hold off (and probably shoot down) the entire air force, particularly with the bag draggers in play with ASAC giving over the horizon cover. The Argentine airforce in contrast hasn't flown any of their mirages in 9 years, they have no credit line internationally to buy more stuff and the average British infantry now looks like a cross between a terminator and Robocop when it comes to basic kit, firepower and body armour.
It'd be different but short of another south american country pitching in, Argentina hasn't got a look in in holding the Islands, even assuming they managed to take them vs the very strong defences at Mt Pleasant.
I'd like to see the Tiffies down there armed with air to surface kit to back that up but generally, the assumptions have been that if we prevent the Argentinians investing the islands, we have succeeded.
