Drewski is pretty far from the mark when it comes to our RPA fleets; we have more than 3, less than 10, several orders already paid for, and some rolling out of the factory right now. We also have some standing agreements with the US Reaper force to allow us to use their aircraft; the whole thing is very mixed together.
REAPER (in capitals) as a UOR is funded until end of FY14/15, but Reaper (the platform) has, according to my Main Building spies, already been funded until the end of FY17/18. Not as many aircraft and ground control stations as the full-up additional capability UOR that people I know are training on right now, but we'll by flying Reapers for at least the rest of this decade.
Beyond that, you can expect that Reaper will probably mop up 75% of the SCAVENGER requirement; and as that was represented by 2 squadrons in the Future Force 2020 concept, I think that means you'll probably find 39 and XIII Sqns, or their successors, still operating happily into the 2020s and beyond.
In terms of manning, I know we currently have 4 RPAS pilots. It's not its own branch, it's a specialisation within the Flying branch, so you can now join as a pilot, a WSO, WSOp, or RPAS pilot. The Reaper force has, at a guess, probably got about 30-40 pilots, expanding probably to something like 50-60 as XIII start operating properly. That means right now, only 10% of our Reaper pilots are RPA-only pilots. While we'll never get to 100%, there will always be traditional manned pilots rolling through, I should imagine we'll want that percentage to increase significantly. We didn't copy the USAF trg system, btw; we sent our trial RPASP guys through it in its entirety, but diverted them to Predators to fit the USAF method. British aircrew converting to Reaper had an entirely different UK-only OCU until we paid into sending guys direct to the USAF Reaper FTU, but then doing a distinct UK work-up on the UK unit.
Anyway, I'd say recruitment for RPASP will be strong and permanent, with an enduring requirement for new people. To paraphrase Drewski, those of you getting keen about joining as an RPA Pilot; do get keen! It's a fascinating way of operating from my experience of it, a fast route to being operational, and if it takes off like it has in the US then an easy route in to a lucrative second career.
People are getting too HERRICK-centric; but anyone who's operated at the higher end of some of our SF stuff in HERRICK and beyond will know that certain people won't go anywhere without a Reaper anymore, so its future's not only virtually guaranteed, but probably going to be very interesting.
