IOTL, the A-7 Corsair II was retired from the Navy and the Air National Guard by the mid-1990s, due probably to the "peace dividend" and the simple fact that the aircraft was a relatively old design (based on the F-8 from the mid-'50s). However, there were some proposals (mainly, unsurprisingly enough, from Ling-Temco-Vought, the manufacture) to upgrade them to serve in a CAS/BAI role with more modern avionics and innards (the precise proposals being somewhat unclear). I suppose this wasn't really particularly likely to happen, but what would it take to have new or rebuilt A-7s fly into the 21st century? Additionally, what would it take for the ANG's A-7s (which were designated as CAS aircraft) fight in the first Gulf war (where, despite being part of pre-war deployment plans, they didn't go)?
