The great problem with the Super Tiger is that nobody else bought it. Australia would have been the launch customer for what was pretty much a new type, with no guarantee of any other customers. Any commonality with USN basic (J65 powered) Tigers went out of the window pretty quickly, with them being withdrawn from carriers in 1961, & from use as trainers in 1967. Australia could have faced the orphan F-111 problem on a much greater scale, after only a few years.The Draken was a good plane but in its initial version would need modification to carry more than one drop tank to meet the RAAF’s ferry requirement. And would still be no match for the Grumman J79 Tiger. Still can’t understand why they never looked seriously at the Tiger. They could have contracted for this plane in 1957 and they could have replaced the Sabre on CAC ‘s production line from 1960. The RAAF could have had the first fully operational squadron with a Mach 2 fighter with radar and doppler nav by 1962. Conversion from Sabre to Tiger would be much easier and the aircraft maintained a much higher safety record in service through to the 1980s. Plus of course the CAC Tiger could be supplied to the RAN to replace the Sea Venom.
If Super Tiger had been bought by the Luftwaffe, then it would have been a safe buy.
