Shame about all those 'other' wars since WW2 that RAF fighters weren't quite able to get to
How about:
Korea no RAF fighters involved but quite a few RAF pilots flying F84s and F86s in combat.
Suez - RAF Hunters flying CAP over Egypt
Confrontation - RAF Hunters and Javelins
Aden RAF Hunters
Dhofar War - RAF Hunters operating out of Sharjah
Falklands - If you study the records of the Falklands war you will see that the Sea Harrier contingent contained a small number of RAF pilots (About one fifth of the total- because the RN could not provide enough pilots). Some of these RAF pilots had been seconded at short notice for the war, and were therefore flying a relatively unfamiliar aircraft, although all were experienced on RAF Harriers.
In action, RN pilots shot down 14 aircraft and damaged 2 others. RAF pilots shot down 5 aircraft, plus a helicopter which crashed while evading attack.
The first 2 air-to-air kills of the Falklands War were by RAF pilots.
Gulf War RAF F3s and GR1s
Bosnia RAF Harriers
Kosovo ditto
Iraq RAF GR4s and Harriers
Afghanistan RAF GR4s and Harriers
Have I missed any?
