Ah, if my information is correct the MoD makes money out of the deal by taking a "brokerage fee" of around 1% of contract value, if the much quoted 20 billion pounds are correct for the whole deal the MoD should net around 200 million pounds.
As for European AESAs, there are lots currently working, CAESAR, RBE2, Vixen and ARTS spring to mind, none of them are operational but until the F35 comes along they pretty certainly will be in operational service.
