This is the Blackhawk airplane that renewed my interest in the Blackhawks after a twenty year hiatus. It was the airplane that the Blackhawks flew in the early 60's, which were my peak years for reading comics. Naturally, the almost archtypical Blackhawk jet has a special place in my memory. By 1957, the Blackhawks were flying a plane that strongly resembled the F-90, but was clearly different. I don't know why the design was changed.
References indicate the same artists drew the comic in both periods.
But after flying this plane for a few years, they found it too large for their kind of missions and, even with the larger engine, it had never gone supersonic. So they gave Lockheed specifications for a smaller, faster fighter. Lockheed probably didn't make much off the original production of six aircraft, but building replacements kept them busy for a long time. The tail is scratchbuilt and the nose was extensively reworked to accept the F-86 cockpit. The Blackhawk insignia were printed with a Star SJ-144 thermal wax transfer printer.
