As of 1953, Convair was in trouble. The Boeing B-52 had kicked the ass of both B-36 and B-60.
Meanwhile the F-102 was an unmitigated disaster, with the prototypes firmly stuck below mach 1, even in dive. There were serious flaws in the aerodynamic design.
Worse, the Atlas corporation wanted to get ride of the firm.

What ultimately saved Convair was the F-102C.
At the beginning, it was to be a J-75 powered F-102, probably a complete redesign.
Yet a lighter variant, closer from the F-102A and powered by a J-79, was studied as an alternative... and collided head-on with Lockheed lightweight fighters proposals.
The J-75 project was soon abandoned, as the J-79 variant had similar performances at lower cost. Soon renamed the F-106, the Convair machine was proposed in two variants
- The F-106A, a day fighter pitched against Lockheed machine
- The F-106B, an all weather interceptor much like the abandoned J-75 project
The Air Force liked the prokect, and ordered both variants. In the late 50's, the F-106A was adopted by many NATO countries, and Japan, as the standard fighter to replace the F-86 Sabre.
The F-106B, by contrast, was only build in limited numbers for the Air Defence Command. 277 were build.
Because convair was so busy with the F-102C, the B-58 entry in service was delayed. IT was fortunate, since the early machines proved beast to fly. It was the YF-102 all over again, to the point that the Air Force suspended the contract late 1957. Convair was left with a handful of YB-58 prototypes and some B-58A.
The company totally reworked its bomber, which resulted in the B-58B, that flew in 1959.
J-79s were now podded side-by-side on single pylons, vastly improving handling in engine out condition. A primitive fly-by-wire system somewhat helped controlling the beast. the pod was replaced with a true bomb bay, and wing pylons.
Overall, the B-58B was a much better machine, and after many hesitations, the Air Force finally committed again to the machine. The Vietnam war, and the B-52 slaugther by SAMs in 1966, showed that low flying bombers were the way to go. The B-58B and B-58C proved their worth, filling the gap between the short range F-105s and the vulnerable B-52s.
Convair importance within General Dynamics grew in consequence, up to the point when, in 1965, they obtained the company original name was brought back.
Then, in the 70's, Convair won its biggest contract ever -the LWF, or F-16.
