how long could HMS Queen Elizabeth and HMS Duke of Edinburgh lasted

But did it work?

Sheffield and Coventry were the radar pickets. Both armed with Sea Dart. Both... SUNK. QED.
Just because the pickets were sunk does not mean they were failures as pickets. The US Navy lost multiple picket destroyers off Okinawa and no one's accusing them of incompetence.

But even with these aircraft carriers of the OP, why risk them when you can lay back and slug the Argentinians when they cannot hit you? Whatever flattops you have should be for the dash in and the dash out. Has no-one ever heard of Guadalcanal?
You mean like the carriers were OTL? Not to mention that both the Phantom and Buccaneer have better range than the Sea Harrier and the proper fleet carriers being discussed can sit back even further.

Ever hear of CARTWHEEL?
Ever heard of the fact that the South Atlantic is not the Southeast Pacific, and has way fewer islands much further apart with a lot less flat ground? There's no Espiritu Santo to use as a logistical hub. There's no Guadalcanal to provide air cover up half the combat zone. There aren't more islands in between to push that airpower closer to the target island.

All there is is one rock close enough to matter, and it's a hell of mountains, fjords, and jagged glaciers.
 
All of this is irrelevant. It is categorically impossible to build a military airfield capable of supporting an invasion anywhere on South Georgia. The terrain is razor sharp glaciated peaks. You cannot build anything anywhere, except on thin strips of gravel beaches, none of which are large enough to build a jet capable airfield.

Establishing a forward FOB for the Harriers was one of the primary objectives of the landing at San Carlos, and it was moderately successful, though was signifcantly hampered the loss of large amounts of material on the Atlantic Conveyor. It is very likely that in a scenairo where the CVA-01 replaces Invincible and Hermes that RAF ground attack Harriers would be taken south by the task force and transferred ashore to a much more extensive FOB that has been set up free from Argentine air attacks. A protection provided by proper fleet air defence.

Anywhere near Stanley was not useable ground, since it was garriosned by near division strength numebrs of Argentine ground troops, equipeed with AFVs, light attack aircraft, radar guided missile and gun AA, and artillery. And as mentioned before is heavily mined. So an invasion of that area would require the mines to be cleared under fire, then a close bombardment of the beach under fire, then a landing of troops be air and water under fire. IF this is succesfful and the inital Argentine defences overwhelemd to create a beachhead, thaen that foothold will end to be continually reinforced under fire with singficant threat of counter attack. Then as troops breakout sinficant ashore facilities and supply depots would have to be established to support the advance, whislt under threat of counter attack and under artillery fire. The people planning corporate had insitutional memory of D-Day when they had done jsut these things, they remembered it sucked. Their response, which was the correct one was to decide they would rather not.

Perhaps Britain could have accomplished such a feat, but it would have been bloody. Which perhaps is not so much of a problem when your centre of supply is across the channel 15km away, and your nation is geared up for total war that it is committed to winning. When your centre of supply is 12,500km away, the economy is weak, and public and politcal support is brittle to say the least, its an entirely different proposition.

Every part of your plan from D-Day down under, to building and operating the Narnia Flying Club is absolutely batshit insane and goes agaisnt every concept of sound military operations.


It would be more feasible to redeploy the BAOR to Chile and invade Argentina over the Andes mountains, than to do what you are suggesting.

Just thinking out loud... If the UK really absolutely had to build a "fast jet capable" air base at South Georgia, perhaps something could have been built slightly of shore ? (Maybe pilings could be driven into the sea bed and a platform built on top ? Or perhaps large floating sections could have been made in the UK, towed to the island then connected together ? Or ??)

I'm thinking this would probably have taken years to complete ?

I share the skepticism of most of the other posters about the likely hood of the UK proceeding with such a plan in the context of the Falklands / Malvinvas conflict.

Well you could. The US seabase project comes to mind. But it would have to be a floating tethered structure built in the UK and then towed south. To keep down the size you might want to fit cats and traps to it. There are after all some available that have just been landed off of the Ark Royal. Its going to need sizable power generation facilities to run the maintenance shops, and since you are building a large floating box of steel, with a hanger in it, and a flight deck on top, you might as well go the extra mile and make it self propelled.

At which point it is an aircraft carrier.

Just to add my 'tuppence' the Airport at Saint Helena was recently opened.....and then shut again due to the sheer cross winds and earning the name "Most useless airport in the world".....and then opened to 737, 757 and Airbus A320 after an extra year of research into the wind sheer issues

I mention it as it highlights the issues and difficulties of building a proper runway down south

In all this time, do the Argentinians put any kind of defence on the South Sandwich Islands or South Georgia?

Or along with all the other idiocy going on, are we to assume the Junta just don’t bother about SG & SSI?

Why would they bother? Is England going to come retake their strategic penguin reserve? It's the same reason you'd be an idiot to put any major formations on West Falkland Island, there's nothing there TO DEFEND!!

Yes, it worked a treat! The Glasgow-Brilliant combo downed 3 A4s on 12 May before Glasgow was damaged and Coventry-Broadsword combo downed 4 A4s on 25 May before Coventry was sunk. Both were subject to the efforts of entire squadrons to achieve this result, soaking up some 10% of Argentinas entire fast jets sorties for the whole war.

This is a bit like the air battles that developed over USN radar picket destroyers in 1945. The Japanese knew they had to eliminate the pickets to get to the fleet so intense battles occurred there, with attendant losses, rather than over the CBG or landing zone itself.

To prevent its use as a FOB, be that as a sheltered place to cross deck supplies people from whatever brought them south to whatever's going to take them over to San Carlos/Teal Inlet/Fitzroy (in the case of S Georgia), or as a Harrier base (in the case of W. Falkland). Not, it must (apparently) be said, to house a regenerated RAF Bomber Command.

OTL there were quite substantial Argentine forces on both islands - two regiments in the case of W. Falkland.

But they’ve had quite a while in the scenario to put something there.

OTL they put a small formation on at least one, would they (with the extra time of occupation as suggested) put more out there? They claimed SG & SSI just as they claimed the Falklands and OTL they’d put troops in pre-invasion, so it wouldn’t occur to them the Brits would do the same in the build up to an attempt to retake the Islands?

The problem Argentina has (as I understand it anyway) is Chile - they don't know what Chile is going to do and have to keep a substantial force back at home to secure a very long border as well as roughly a division on the Falklands themselves. How much manpower (I genuinely don't know) did they have spare to garrison specks in the ocean?

I don’t know, but any level of troops with a radio setup mean the “British building RAF Arse End Of Nowhere on an inhospitable Island” plan becomes a contested operation.

I kind of feel this doesn’t need to be stated (but the level of stupid may require it to be) but you can’t build a 3,000ft runway base overnight and in one trip. The equipment and personnel required mean several convoys to and fro. A company of Argentine infantry with a communications element mean, even if they can’t keep the initial element off the island, that the returning convoys will meet opposition on their way to SG & SSI and the idea of a “surprise 16-year-early jet attack” loses the element of surprise.

I agree with your reasoning for the 'garrison' (no matter how small) and I suppose that in a competent Western army you could do the job with a platoon and a couple of attached Scaleys (if they're just there to monitor the area for someone building Heathrow on top of a glacial mountain). Call it a company with an attached heavy weapons platoon if you want them to be able to interfere with any landings that may be attempted.

So long as they have enough pack fuel to keep a gene running for battery charging and the QM has arranged for a year's supply of Menu A rat packs they could theoretically sit there until the food ran out or until someone finally broke after eating nothing but lamb stew and dumplings and treacle track pad for six months and murdered everyone on the island.

I wonder if, between the paranoia of a dictatorship and the possible lack of training of a conscript army, they would have trusted a small independent force in the same way as the British Army would?

That is a very good point I’d never considered.

OTL they’d snuck (according to Wikipedia) some men onto Thule Island in the 70’s, so there is precedent?

As it happens these achemes were addressed to an extent IOTL according to Commodore Michael Clapp, commander of the Amphibious forces, who wrote the best of the autobiographies of the Falklands.

In the first conference or two Sandy planned to land on West Falkland and the troops would build a 6000' runway to operate phantoms. Clapp had to tell him that the landing force lacked the heavy equipment to undertake such a task and even if it did the job would takes weeks or even months so couldn't be completed before the southern winter set in. As a submariner Sandy didn't accept this advice and Clapp had to undertake time consuming work to prove his point before it eas dropped.

On the other hand what the British did do was build a 800' runway from 22 May which was declared open to Harriers on 5 June. This was built without heavy equipment in 15 days, illustrating what the British could do with what they had.

You can infer the art of the possible from these 2 situations.

While we're on the topic of CVA01 and the Falklands, what about the effect of these ships on British radar development? The CVAs and T82s were supposed to be equipped with the Anglo-Dutch Type 988 3D radar, but this was cancelled not long after the carriers. Apparently the fallback was an electronically scanned version of the awesome for its day Type 984 called the 975, but I don't know if it would have gone into the T82s as well. In the end the CVAs and T988 and T985 were cancelled, the Ark got 2 x Type 965 AKE2 'double bedstead' radars and the Bristol and early T42s got single T965 AKE2s.

So if the CVAs get built and presumably 4 T82s, does the T988 radar get cancelled or do all 6 ships get T985s? How do these radars go in 1982 compared to the T965s which were useless below 120'? Would Sheffield have been sunk if she was a T82 fitted with a 988 or 985?

That was, apparently, a team from the Argentinian Air Force (presumably along with scientists of some kind, since it was supposed to be some kind of research station).

It'd be interesting to know who they were - professionals or conscripts, combat troops or engineers/signals, etc. They didn't put a fight up when the Royal Marines landed after the Falklands War to get rid of them.

Just for giggles, how about we get back to the OP’s point? Or has this thread been derailed into “USM South”?

I believe that two Fleet Carriers like the ones suggested would be in service until at least 2007 (giving them 40 years). If most things go OTL apart from the Carriers, there’s a good chance their replacements would be well on the way by that point too. The use of two assets like that would have proved their usefulness and the Navy would be built around them. The replacement of them would almost be a “no brainer”.

I'd have thought that they'd have a fairly significant effect on the escort fleet. Does the RN end up with eight Type 82's and a couple of helicopter escort cruisers and if they do how does this change the requirements and procurement of the rest of the escort fleet?

No way the planned 'Invincible' cruisers would have been built, barring a major improvement in the UK's finances, IMO. They're easy cuts for the Treasury - 'you've got 2/3 55,000t aircraft carriers, why do you need helicopter carriers too?' It might not make sense militarily but it does to people who think of everything in pounds, shillings and pennies.

Not sure about the 82s though - if the RN isn't going over to being a pure ASW force as planned they make sense as escorts for proper carrier groups but the Treasury might fight to force them into taking the T42s instead.
