Their ASW assets are not good enough to guarantee to kill an Astute class sub.Which really is what you need or your fleet becomes scrap.
Airforce does not yet have something to equal eurofighter.Without that their not getting ashore.
it depends - yes, in qualitative terms they are well behind - the carrier flies A-4 Skyhawks, and the air force flies 12 Mirage 2000, 50 F-5's, 50 AMX, and a handful of P-3's with Harpoon and some tankers. if they were magically transported to Southern Argentina then they could give the current 4 Typhoons a good shoeing - quantity has a quality of its own, but you can't stage a deployment like that without making a lot of noise - which we're listening for, and have a plan in case we hear it.
with the SSN's, they don't need to kill them, they just need to drive them off for long enough to do their business and get home. now, currently thay don't have the ASW capability to drive off our SSN force to the satisfaction of the captain of their one and only aircraft carrier, but they are working on it - they're already upgrading the P-3's (BAES are doing it for them, they probably won't be far off Nimrod MRA4 or P-8 standard when they go back into service), they are looking to replace the A-4's with something in the F/A-18E/Rafale/SeaGrippen/MiG-29K class, and the Air Forces' F-5's will be replaced by the same aircraft. they've also been sniffing around the CVF project, and have said that they've give one of them a home if we end up selling...
if they tried it now it'd be bloody, with massive losses, but they might succeed. if they try it in 10 years it would be far more evenly matched (unless we've got F-35 on the Islands or on CVF - in which case they'd be fcuked), their losses would be far fewer, and they'd have a much greater likelyhood of success.
