What BAe can charge the Military !
Wonder why the government chopped up those new Nimrod's ? It was to show BAe that they would no longer be suckered into another progect that BAe could massively overcharge for. The first time the government dropped the hint was when the Bulldog life extension program was ditched in favour of the Grob 115 Tutor, Unfortunatly for BAe that not being very bright they failed to get the hint.
It might take 500 man hours to do the first aircraft as you sort the problems and tooling buy by aircraft 5 or 6 I think that you would get the job down to just under half the time it took to do the first aircraft.
