So a bleed air turbo compressor style ACM (Air Cycle Machine), that's been used in commercial aviation across the board for 50+ years. Only difference here is they are dumping the waste heat initially into the fuel, before a fuel heat exchanger pumps it via some means to an engine bypass duct where it is "hidden" in the engine exhaust. I wouldn't be surprised if they are using a Galden loop system at all as its efficient if a little heavy.
Refrigerated Cooling for certain systems and the cockpit is from a closed-loop air refrigeration cycle, which works by expanding engine bleed air across a power turbine. Waste heat from this and also other systems is transferred to fuel and then to a heat exchanger in the engine bypass duct.

They also cite The Aviationist and I am convinced The Aviationist reads ATS. So maybe this will become a complete circle.

*I was under the impression its performance compared to the F-16 was that, one had a better roll rate than the other, while it was the reciprocal with instantaneous turn rates.
*Interesting that they may have left the external tank plumbing in the build. I would have thought that was an early weight saving casualty.
*Also interesting that canards were dropped for reasons other than stealth profile. Does that mean that the often quoted view that canards are detrimental to stealth performance was/is untrue or that regardless of it either performance was more important, or they were always willing to accept some all aspect LO degradation in some quarters anyway, but performance in the transonic was the real issue? Who knows.
*Im surprised they just dont admit to a towed decoy.
“The Government of Australia has requested the sale of one thousand nine hundred fifty-two (1,952) ALE-70(V)/T-1687A Electronic Towed Decoy Countermeasures, publications and technical documentation, other technical assistance, U.S. Government and contractor engineering, technical and logistics support services, and other related elements of logistical and program support.
This sale will contribute to the foreign policy and national security of the United States by helping to improve the security of a major non-NATO ally and continues to be an important force for political stability, security, and economic development in the Western Pacific. It is vital to the U.S. national interest to assist our ally in developing and maintaining a strong and ready self-defense capability.
The proposed sale will improve Australia’s F-35 survivability and will enhance its capability to deter global threats, strengthen its homeland defense, and cooperate in coalition defense initiatives. Australia will have no difficulty absorbing this equipment into its armed forces.”
