Found this while looking up A-7Ds. But it has quite abit more including pretty much all USN, USAF, Marine and FMS Phantoms
the pages are quite lengthy, as it takes each s/n and gives its unit assignment history as best it can
also, like with any such site, do take things with a grain of salt and pay attention. if a given aircraft was with the 166th TFS from 81 - 88, the 112th for 89, then back with the 166th until retirement in 92, you may be able to discount that assignment in 89 (without photo evidence). but then again, no site is perfect, not even f-16.net.
anyhow, just thought i'd share
