Wing Commander, a Deputy, Staff Officer positions, staff enlisted, then double that manning at each Squadron....and Flight Commanders.....that is several Manning Points.
Now in the old days.....when Aircraft could be built in a timely manner and forces being boosted in numbers rapidly.....those units could be fleshed up with the existing troops being the Cadre of those bigger units due to the initial expansion.
But....when was that the last time that ever happened in the RAF or will ever be for that matter.
We have to remember the UK Military is on the decline in size.
Even with the arrival of the P-8s......that fleet is smaller than in the past and despite better capabilities of the aircraft the loss of numbers limits the overall capability due to sheer lack of numbers of airframes.
