There was an issue of World Air Power Journal (RIP) that I once owned
that most definitely had a short feature on SHARs carrying AIM-120s,
and I seem to recall the four-shot loadout in some of the pics. But
that was a long time ago and I sold off my collection of WAPJs a few
years back, so I can't give you a specific issue.

Might have been the same source, but I've seen SHARs with 4 -120s on more
than one occassion. Dwarfed the fighter and really put its size in
perspective!
