Why F-101/F-105/F-106 never exported?

Question

If any of you are familiar with the century series of fighters we've seen that the F-100 and F-102 was exported to Turkey or Greece at one point and the F-104 to various nations. Why weren't any of the other mentioned fighters ever sold abroad? (excluding Canada's F-101s). The next generation F-4 Phantom meanwhile was widely exported.

They were built in lesser numbers I know but a good number of all those types still ended up in the Davis-Monthan AFB boneyard. Were they just surpassed by other fighters like the F-4, Mirage and other types that quickly in the 60's? or, on the other hand, did the US did not want to export them during the 50's?

Answer 1

The problem was limited production runs. Only about 800 F-105s built, only about 330 F-106s.

I think some F-102s were exported, but 1,000 of these were built. There were never enough F-105s or F-106s, both of which were also very expensive, to export them.

Also, both fighters carried technology that the USAF probably did not want compromised at that time. Had any country very friendly to us been willing to fork over the big bucks needed, however, it's possible an export version might have been approved. Obvously that never happened.

Far as I know the only country interested in the F-101 was Canada, which used the interceptor version.
