Beagle/Wrathmonk- You have to define responsibility in these cases. Is it the 2* who thought up the idea, the 2* who approved it, the 2* who accepted changes to the specification or the 2* who accepted it into service? Some may well be the same but on a project of this size and complexity it would cerainly take longer than the 2 year effective tour length of the 2*. This sort of thing is to be expected the way we 'manage' careers.
