AP - or perhaps conduct a long range recovery of personnel. But the UK isn't in the JPR game, and has firmly handed that over to the "coalition".

What happens if you decide to get into another fracas sans a Coalition?

How long would it take you to kit up, train up , and deploy into operational readiness?

It doesn't bear thinking about.

It will simply be a "risk" that is likely tolerated or treated in an ad-hoc manner.

My point exactly Alfred, we need to be able to do these things at shorter range before we get wrapped around the axles in self flagellation for not being able to do a niche skill like AAR. The UK had a burgeoning CSAR/JPR capability and I believe we were told to stop doing it as it wasn't going to be funded or a role that we declared.
If we had to do something long range outside of coalition then I guess we would have to hope that there was somewhere that we could set up a FARP and do some buddy-buddy refuelling, which is at least something that is relatively easy and safe (enemy threat aside) to do.

Display of ignorance alert: How many helis have the probe under/inside the disc - none/some/most/all?

I'm pretty sure the answer is none. You really really don't want the drogue entering the downwash of the blades.


Quite a number of helicopters have the probe ending inside the disk, so the basket goes under the blade tips; certainly the Pave Hawk I flew was so designed. Because the AAR has to be carried out at fairly high cruise speed (for the benefit of the fixed wing tanker aircraft), the downwash of the main rotor blades isn't a major factor.

You may be right. As for the Pave Hawks, their probes (like the Chinook's) are telescoping. When telescoped out, the probe tip terminates just at the blade tips. This prevents not only drogue/downwash interaction, but also prevents the blades from striking the drogue/hose. In the event the blades droop downward under load, the blades will strike the probe and not the drogue or the hose.

KenV...

I'm fairly well aware of how it works on the Pave Hawk.

As I wrote, I've flown it and carried out AAR on that type.
