I was reading a book on the history of jet fighters. In the book there was a part in the book that said the USN had plans to replace the F-14A TF-30 with after burning Allison TF-41 that produce 18000 lb of dry trust. I find this funny because the A-4 had one j52 and the A-6 had two j52 and the A-7 had one TF-30 then TF-41 and the F-14 already had two TF-30 so if they put the TF-41 on the F-14 it would compete a four some in the USN air power.

IIRC, the F-14A was originally to have a GE engine. But that engine was not ready in time (it later, much later, became the F-110), so the USN had to then chose between the, then available, TF-30 (going into USAF F/FB-111s) and the J-79 (going into F-4s). The TF-30 was selected as it needed less engineering work to adapt to the airframe, and the airframe to it, had more thrust, less smoke, and burned less fuel, than the J-79. The J-79 had an advantage in being able to with stand higher "G" loading, and was more reliable.
