What? The SR-71 was a strategic reconnaissance aircraft. It was not, and never was, an interceptor. And the F-35 was never tasked with replacing an interceptor, but is a slow-ish multirole aircraft with a heavy emphasis on strike capability. And the USAF hasn't had an "interceptor" in decades (single mission, short range, high speed, point defense aircraft).
