How did the UK get here? OK, never mind how, we are here and that's that.
How do we get out of here?
Mothball the carriers, bin F35 (all versions) for five years, and then reassess when many of the interdependent variables have been reduced, and the risks acceptable.
Continue with Typhoon and Tornado, improve sensors, weaponry and defensive aids. Replace Tornado around 2025. This might be F35A or improved Typhoon or whatever, it's not clear right now. The money saved on carrier operations and F35 acquisition and operation has lots of alternative uses in the meantime, and many of them we are far more likely to need than a 'Day 1' stealthy strike capability deliverable by a handful of aircraft.
Not what I would wish to see in better times, but a realistic response to the Class 1 mucking fuddle we are in right now. We cannot afford a carrier capability with all that entails to do it properly. If we are only able to do it in a half-arsed way, it's way, way too risky to put such a high value asset and prime target in harm's way with inadequate and underdeveloped airpower.
