The F-111 Aardvark (McNamara’s SECOND folly) had technology that really pushed (and perhaps even pushed past) what technology could do at the time in a whole lot of its components, technology soon to be replaced by just finding a better technology altogether.p. Originally, it had some of the most capable (if unreliable) analog computers ever built. But when those analog computers were replaced by digital ones that took a tiny fraction of the electrical output, it had enough power to operate some serious jammers, and as the “Spark Vark” the EF-111 was really pretty capable in that role - as long as the rest of the aircraft happened to be working that day.
