A Separate Air Force
The US followed the RAF, albeit almost 30 years later. As the USN and US MC, like the FAA, retained organic Air it was the Army that lost Air.
While the sizes are different the logic for abolition or retention must be similar. The Canadians restored the RCAF after an interval of 43 years.
For the MOD to be forced to disband the RAF, they would be running counter to experience or leading the field.
