Can't be that old, has to post-date the declassification of the F-117A in 1988. On the other hand, has to predate the subsuming of McDonell-Douglas into Boeing in 1997.

I was going to try to get more specific by figuring out when exactly Grumman (maker of the F-14) and General Dynamics (maker of the F-16) got subsumed into McDonnell-Douglas, but it turns out that they never did, they wound up in Lockheed. So whoever wrote this clearly didn't know all that much about fighter aircraft.
