Orac
Since we don't know the number of pilots and airframes involved, this figure is a guess. Let's just wait and see.
As to the Nimrod, is this the start of the RAF now planning to invoice the other services for work it does for them
Might as well let the Army take over JHF on that basis. MPA run in future by the Navy? Why not when the RAF seems less interested in fighting to retain "non core" activities!
