That was my point! Indeed, an RAF pilot shot down an enemy aircraft AFTER the RN sub sank Belgrano, so the Navy is more out of date than the RAF in that respect!
RAF Nimrods guided attacks on Iraqi ships in 1991, assisting in their sinking, etc. So that is why the oft asked question " when did the RAF last shoot down an aircraft " is an idiots question. Deterrence is a better application of force than shooting down.
