What is the device at the tail of the F-16 Block 60? The F-16 Block 60 has a lot of advancements, one of which is the device at the tail. What is it?




For clarification, I believe all these vents (second image) are for said device.
That’s a ram air intake and exhaust for a heat exchanger used to cool the Falcon Edge Integrated Electronics Warfare Suite (IEWS). The system remains fairly clandestine, but a few of its components are known to exist.
