The Hunter mixes good lethality with excellent handling and a high thrust/weight ratio. From the Mk 6 onwards it has twice as much installed thrust as a J47-powered Sabre, and still significantly more than the Canadian or Australian Sabres, both of which would have been re-engined. It always lacked internal fuel though, and while most export customers (starting with the Dutch) fitted them with AIM-9s, this was never a standard fit on RAF aircraft. Given that Hunters would have been used in RAF service for air defence long into the 1980s, the retrofit of AIM-9 onto Harrier GR3s that happened in the Falklands would probably have happened to the remaining Mks 6 and 9 in the same time frame. UK fit would probably have wound up being AIM-9B or -9G on the outboard wing pylon, as was the fit on TWU Hawks in the same period. Hawk T Mk 1 vs. Hunter would be an interesting fight. In terms of direct comparison, the Hunter would try to get a supersonic opponent into a turning flght. Woe betide the F-104 or Mirage III pilot who gets slow with a Hunter. The F-100 is an interesting comparator, because, despite nominally supersonic performance, the F-100 has lousy handling characteristics. If you want a contemporary supersonic aircraft that can turn at high subsonic,you have to look at the MiG-19 or, even better, the F-8 Crusader. Other interesting options include the A-4 Skyhawk or even the Gnat or Ajeet, both of which are very agile, but lack firepower. The MiG-17 is probably the most realistic opponent though, and a decent direct match.
