Coupla points on this subject....
From a previous post I made on this subject
1) Yes the NFTC Hawk 115s are lovely cockpits but unfortunately serviceability is not much good...(what do you expect with a 30-y old design). Recent furore in the Danish press about the huge cost of NFTC vs. the delay in generating pilots due to much poorer than planned Wx and inability to generate sorties due to 115 availability
2) You can't replace the Tucs with Hawks for the pure reason that they are knackered. They start to die off in 2007 and therefore you need to make a choice on new FJ now - Tuc will survive for the time being one suspects...
3) Despite there being a good field of candidates (MB-346 / T-50 / L-159 / etc) No doubt (much like A400M) the decision will be a political one (entirely unlinked from the fact that most Brough workers live in John Prescotts constituency) and that, I'm afraid means a wonderfully instrumented Hawk that won't last the life or meet the real expections of future fast jet training.
