Indeed, you're probably on to something. I think the Fourth Generation fighter page has really helped clear up things and added some much needed depth. If it is something that could be agreed on by the whole 'community' than perhaps there could be a seperate page for each generation of fighter jet linked from the main fighter aircraft page(and perhaps prop fighters as well). Until then though there isn't really any sort of guidline as to this specific page other for the sake of completeness. It is in my opinion that until seperate pages are created for Third, Second and First generation fighter jets then I don't really think the addition of one aircraft will really cause a lot of problem until such action is undertaken. Especially given that pretty much every single jet fighter is already on the list. The days of where nearly every country could create their own fighter like in WWII are long gone. Perhaps to at least organise the clutter, rather than listing aircraft vertically, it could be done horizontally like with the inter-war aircraft to at least make the page 'shorter'. To stay on topic though, is it agreed that the Mitsubishi F-1 is indeed, a fighter aircraft?
