Well if we're looking for light relief how about a balloon towed behind a frigate traveling at speed with a hose and drogue streamed out behind ? The problem maybe the F-35 would use more fuel hovering faster than they could take on replacement volumes.............
Seriously tho the critical question is are they ever likely to be involved in a medium to high level conflict in the next 40 -50 years - I can imagine a series of low level actions, and I can't see the UK in a high level conflict on it's own. Historically I'd guess the Falklands would be the classic example - so one in 70 years?
