Admin Mod, if this is in the wrong place please move it to the correct place. Thanks I'm trying to help my son on a school project. We are trying to consolidate what the most important jets in US military history and need some strong resources. For instance, I think the F4 Phantom is important as it evolved into the F15 or F16 (I think) but need to find someplace to verify. Also what does the "A" dsignation, as in A-10 stand for? Any guidance will be greatly apprceiated.
