Leon,
Sorry, got to come in here. The question is: 'when did the RAF last score aircraft kills after WW2?'. The answer is 'none' except possibly from RAF Spitfires in Israel in '46 or 47.
The RAF scores an air to air kill when an RAF aircraft does it. That's an aircraft on the RAF military aircraft register, operating under RAF command. Fact. Not open to discussion. Now, if you WANT to go down the 'kills are awarded to the pilot and not the aircraft' route, let's just unpack the Battle of Britain, or perhaps not? Any takers?
There is NO Navy snobbery, or playing down the role of RAF pilots in the Falklands - on Sea Harrier they were bloody good squadron members playing key roles. 1 Squadron were recognised and applauded by the Navy as the professionals they were. My unit picked an RAF guy out of the water after he was shot down, and he remains a true friend to this day.
The problems start further up the chain when inter service 'willy waving' starts. We ough to do our best to be better than that. However, the facts are there - no RAF air to air kills since WW2. It's inconvenient for some in the RAF but true.
best Regards
