Yesterday in the UK, the two new CVF class carriers "HMS Prince of Wales" and "HMS Queen Elizabeth" were given full go-ahead and funding for construction. With in-service dates of 2014 and 2016.
Significantly, this go-ahead included the descision to use a ramp rather than EM Catapults in the ships initially although they can be retrofitted with them if necessary.
What does this mean for F-35? It means the UK is now officially commiting to the F-35B rather than a mixed fleet including the F-35C (this decision dictated what was to be procured).
The CVF class has a combat wing that will include up to 40 F-35B (realistic more around the 30-35 when factoring in helicopters).
Sadly, it is unknown if E-2D will be procured, I know tests are currently undergoing in the US to show the E-2D can take-off using a ramp however, there are no plans for arrestor gear to be fitted to either ship. So for the AWACs component the current favourites are the proposed AWACs version of the V-22 or the Merlin.
Size wise, approx, only US carriers are going to be bigger. Although I don't think it is smart to only have 2 carriers, 3 minimum should be acquired imho. France is also looking at purchasing a CVF class carrier fitted with EM catapults to supplement the Charles de Gaule.
