The sad fact is the only way to save significant amounts of money is to lose capability. We've seen that before when we lost Jaguar, Sea Harrier, Harrier GR9 and Nimrod. In that respect, the BBMF and even the RAFAT are relatively small pebbles.
Which in itself is a short sighted cost saving exercise that has a knock on effect on the other fleets that have to take up the slack and thus burn through their fatigue lives and projected out of service dates earlier, unless you bring forward mid life updates etc to extend them.
