IIRC, the Navy and USMC were still using the Mongoose as an adversary fighter in the 80's. I may have recalled incorrectly, however. I also seem to recall that some of the reserve USMC outfits had the A-4M still alive and well back then.
Hmm, from the wiki page, it looks as though memory serves:
A few snippets:
A-4M used by both VF-126 and TOPGUN.
A-4 remained a viable threat surrogate until it was retired by VF-43 in 1993. The A-4M was also operated by the Operations Maintenance Detachment (OMD) in an adversary role based at
NAS Dallas, Texas for the Naval Air Reserve.
I seem to recall VF-43 also having some Israeli Kfir fighters for a while.
FWIW:
Collings Foundation has a TA-4J still flying.
Nice to see the folks in Brazil are keeping the Skyhawk alive. ( I suspect their avionics suite is quite different from the old Skyhawks some of us are familiar with ... ) From the site linked (Portuguese?) it looks like they are a variant of the Mongoose, with nicely updated displays and avionics.
