As I said before, it would never be a Nimrod but it would answer all those woe-is-me-we-have-no-SAR points that keep being raised.
What could a Nimrod that a P-8 can't do as well or better?
Or, if you want a turboprop maritime patrol plane, let's compare the merits of Marshall's C130 mods. to the price and capability of a rebuilt and modernized P-3? There's going to be some such P-3's on the market.
Maybe the RAF could benefit from having a couple of AC-130's. That's something to talk about.
