HAHAHAHAH! it is Convair 200A, the first JSF concept.
It had nothing to do with JSF. It was a radar equiped supersonic replacement for the original Harriers. It would have been used aboard the Sea Control Ships to offer a longer ranged air defense than was capable with Sidewinders. In the end it (and it's competitors) lost to an upgraded Harrier (the Harrier II/AV-8B). There was a CATOBAR version proposed, but even that was dropped when the VTOL contract went to the unsuccessful XFV-12 (who's models showed that it should generate more lift than it did in the real world - hence showing limitations of models at the time).
