NPAS have put out a government tender for industry to run NPAS and London [separately] as well as provide new airframes.
This was something that was explored a year ago but I am not aware of the interest in any industry feedback.
Aside from the sheer cost of this plan, Howe anyone expects industry to get this up and running in the next 50 weeks escapes me. It took a decade to arrive where we are and I cannot see anyone undoing that little lot in the time allowed. If industry takes it up perhaps it will shut down most of it and restart each element when it can get it to work to their standards.
