HAS59,
The role of Wedgetail is completely and totally different from the role of Sentinel. You might as well say we will be better of with Grob Tutors!
And for all those pushing the P-8A as an alternative to Sentinel, the RAF have already formally declared that this will not happen as there are nowhere near enough of them and they will be 100% focussed on the Maritime role.
So we will withdraw the capability unreplaced and suffer yet another Tory capability "window" or gap.
