Doesn't matter how you weight it up there's no way a single Nimitz Class strike group could trump two Queen Elizabeth Carrier strikes group no chance not in a 100 years, you are talking about each single Royal Navy carrier having two Daring Class DDG let alone the capability of just one, four Daring Class would ensure nothing screens past them without them knowing, you are also missing out two very very formidable SSN two Astute Class which could hold of single Virginia Class.
Sorry my friend, Asif, you are missing out on, and wholly diminshing the huge difference the long range E-2D AEW makes in being able to locate and then direct strikes against an OPFOR.
Without this significant AEW coverage similar to a Hawkeye, the Queen Es would be horribly dis-advantaged...both of them, against any single Nimitz. That's just the hard cold reality, and there is no way around it.
Out in the far reaches of the ocean, far from land based air, where they would most likely meet, the US carrier would find the UK carriers and then be able to relentlessly hammer them, the large strike forces launching their standoff weapons against the Darings in large numbers until they were overpowered, and then going for the carrier.
Nothing is a sure thing...but a single Nimitz with its airwing and the AEW, EW capabilities of the Prowlers and Growlers and then the F-35C and Superhornets, would have a huge trump card on the UK carriers. You add the CDG CVN into that mix with the Queen Es, then that is a different matter, because it does have that AEW component and its air wing to boot. In that case it will take two US Nimitz CVNs.
The decision to go STOBAR took away the ability for the UK carriers to enjoy the huge and critical advanatge. As a CATOBAR they would have had the Hawkeye, the F-35C and probably the Growler. As a STOBAR the have none of that...but the US does.
In addition, the four US escorts are going to have 448 missiles between them. The four RN escorts are going to have 192.
The Astutes will stay close in to the carriers to protect them, as will the US SSNs assigned to the CSG...but the US enjoys such a huge numerical advantage in SSNs that they would have numerous hunter/killer SSNs searching for the Eurepean SSNs and CSG and engaging them.
Anyhow, I believe the UKs Queen Elizabeth carriers are great vessels. Against any potential foe in the foreseeable future, they will be more than adequate...but not against a US CVN.
As to the UK CATOBAR not being able to surge two and the UK STOBAR being able to surge both...that is simply not correct. Both of those vessels engineering spaces would be very, very similar except for the cats. Both of the types of vessels at some point will have to have scheduled, long term overhauls for maintenance, interspersed by short term overhauls.
During the short term maintenance periods, yes, either CATOBAR or STOBAR would be able to quickly surge and go in relief or in concert with the other carrier, and the UK could put two to sea at a time.
However, both the STOBAR and CATOBAR variety will have a very difficult time doing that during any major, long term, scheduled overhaul. As a result, there will be times when there will only be one UK carrier availabe and that would be true for either CATOBAR or STOBAR. The decision to change from CATOBAR to STOBAR, IMHO, was purely couched in finances (which over the long term do not make sense), and were probably far more political in nature playing to particular constituencies of the PMs making those decisions.
Obi Wan...could you weigh in here?
Anyhow, sorry we disagree Asif...but it is clear we do. Outside of national pride, there are certain critical technical realities in play here that make what I am communicating to you trancsend the nationality...it would hold true if the roles were reversed.
As it is, as I have said several times now...it is really immaterial. The two forces will not be pitted against one another in combat, so there is absolutely no sense in getting too worked up about it.
