I was taught a long time ago that RAF == Royal Air Force.
There isn’t really much left of the Royal Air Force- perhaps everyone considered the RAF initials as available for recycle.
Leaving out training and executive transport, with which they are well stocked, fixed wing assets:
24 C-130s
1 A400
18 C17
Support
10 Airbus tankers
Recon
1 RC135
5 EC135
3 BN Isslanders
5 Raytheon Sentinels
6 Beachcraft Shadows
Combat
102 Tornado (scheduled for retirement within 50 months)
125 Typhoons
4 F35B
