The original reason for setting up the RAF was strategic use of air power, this was first identified in the report by LT Gen Jan Smuts in August 1917, Smuts commented
"the day may not be far off when aerial operations with their devastation of enemy lands and destruction of industrial and populous centres on a vast scale may become the principal operations of war, to which the older forms of miltary and naval operations may become secondary and subordinate".
Following the demise of the Vulcan some say that the RAF can no longer forefill the role it was set up for and should be dissolved back into the other services.
I do not hold this veiw but as you raised the prospect of the end of the RAF I was think it was time to play devils advocate.
