It seems like Turkey has been able to leap & close key technology gaps in 15 years time. Any guesses on how this happened? Is Turkish investment in Def R&D is so high & that too in many areas simultaneously to close gaps or is it all blowing a bunch of hot air? Its GDP is around 1T$ as o...

Not IR...but that port has been there quite a while. IIRC, it is a spring loaded port which opens only during times when excessive air is needed by the engine...like take-off etc. I think the aux. port was added when F404-INS6 was installed as it was determined that engine needed more air flow rate.
