Different questions....Tasking and Capability.
It one thing to say the RAF has not been Tasked and an altogether thing to suggest sufficient assets to be capable of meeting the Tasking unless that Tasking is tailored to the Assets available...which then begs the question of whether there are enough Assets to be effective.
At some point....any force can be too small to be genuinely effective no matter the capability of its Fleet of Aircraft.
As the RAF is so quick to do....the Battle of Britain might very well have gone the other way had the Fighter Force been much smaller and the Aircraft Industry unable to replenish the losses in aircraft.
As it was, the RAF nearly ran out of Pilots towards the end and had to draft in replacements from other branches of the RAF and Commonwealth Countries as well as from foreign sources.
Has the RAF lost that ability to replace Aircraft and Pilots should it be engaged in a full fledged War?
