The F-89G was a proposed advanced version of the F-89D. It was similar
in many respects to the F-89F, but it retained the pair of 7200 lb.st.
Allison J35-A-35 afterburning engines used by the late F-89D.
The F-89G was to have carried the Hughes MA-1 fire control system that
was being developed for the XF-106 project, and was to be armed with
Falcon air-to-air missiles. The F-89G never progressed any farther
than the design stage.
