Rotary AWACS (that is what it needs to be to support JSF, not simply AEW) is not going to work. Helicopters do not have the speed to get the distance they would need to go in support of a JSF mission. We are talking with JSF of an aircraft with a combat radius in the region of 800nm. Why not try a bigger radar and have it closer to the ship. Don't think that would work either.
So I think somepeople in MoD may have at last realised the above, hence the delay as a rethink is thought about reference conventional launch and recovery - which has been driven not by the JSF but by the AWACS requirement.
It is my own sad opinion is that it is all academic as CVF just wont happen. In the next parliamentary term, according to Adm West at a recent Commons Defence Select Commitee, a replacement for Trident will have to be discussed and put in progress. The defence budget is simply not large enough to support both those projects simultaneously.
No British government would be willing to give up its seat on the Permanent UN security council, but it would be willing to give up carriers - as it has done in the past.
