I have many resources (including original NAA 40's and 50's magazines) in regards to the FJ Fury line of A/C. I can find nothing that states the FJ-1 was a direct descendant of the Mustang. What I can tell from what I found after researching your question is that The FJ-1 was designed with a similar shape due to the success NAA had with the Mustang. Consider how different the airframes had to be just to accommodate the jet engine. Like you, I have heard the FJ-1's were just Mustangs with jet engines. I don't believe it is that cut and dry. Perhaps someone out there can tell us for sure. 03/14/2008 @ 17:27 [ref: 20020]

Hi all,
Can anyone confirm for me that the NA FJ-1 Fury was a direct descendant of the NA-73/P-51 Mustang design? Certainly the empennage looks to be, and I have heard that the wing was the Mustang wing with strengthened spars for added G-forces. But I am unable to find any positive proof that the Mustang was the airframe that the FJ-1 was derived from.
