Expertise is gained over a fair old length of time, not something that a handful of 'seedcorn' can upload into a few dozen ab initio students x years down the turnpike. Any significant outflow of sqn aircrew from the RAF would be very difficult to replace.... you can't teach experience, and the experience of aircrew on their Xth tour is what we'll be missing.
I'd want an aircraft with Searchwater in it, and a significantly good TAC NAV kit... I expect the wetties would like a darn good processor array too. ... Hmmm, I suspect I'm designing a Nimrod inside a different airframe here...<g>
