The things the NFZ are likely to demonstrate are :
1. Need a SEAD capability, which UK is ill-equipped to provide and if the boxheads aren't playing leaves us waiting for the nearest sqn of Prowler/Growler.
2. Depending on what FOB is used, the number of cabs required (even with tanking) to maintain a mere two-ship CAP is going to be eye-watering - my bet is 8 cabs per two-ship station for any length of time. Ark plus GR9 unlikely to be able to do much to support this. Even with FA2, would have struggled to do much more than a couple of CAP stations for any sustained period. BUT
3. That's why you buy bigger carriers with the ability to run multiple CAP stations and do SEAD/strike from the same airwing. Can get closer therefore getting away from the two hours lost transit to station & return. Would still need AAR & probably AWAC, but much less demanding than filling CAP stns.
