Well the incremental software phase has been completed for EODAS for the LRIP, but the IIR integration that identifies targets automatically was just started this year so that's a trick having it ready today.

You're moving the goalposts now, you said nothing about the AI in the software that automaticlly identifies the targets in the imagery. Just to be clear here is what you said:

"EODAS depends on IIR technology mated to the helmet visualization. That's not due for several more years."

See, nothing about identifying anything.

Madrat you are wrong again. They did not say that the software was done for SOME of the JSF's functions, but for ALL JSF functions. Try again.

Steer this back to the "Low-end Raptors".

Low-end Raptors are a bad idea because all the potential advantages vs the F-35 (the most similar aircraft) would be completely eaten away by the costs of developing, testing, and setting up production of a new Raptor variant. It would also suffer from small lot size whereas the F-35 would almost certainly be able to leverage huge economies of scale in a global network bringing down the cost of everything from maintenance to training.

We keep getting back to costs. The customer, the Japanese, were not worried about the costs. If we discard this argument then we are left with Congress being the only real barrier to an export Raptor.

They were! Why do you think they didn't press the issue harder? They would have had to either cut tons of programs or increased the top-line of their defense budget (not easy in Japan):

For the 'low end' F-22 program to have worked, it should have been integrated into the design concept from the beginning of the program. Now we are in a situation or approaching a real cross roads where our allies are facing increased pressure from new systems from Russia, China and, India such as the Sukhoi T-50 and will be exported to their allies. Russia has already stated it will export their new fighter to their allies. What 'if' Russia exports the T-50 to Syria in 10-15 years from now, will Israel have a competitive fighter in the F-35? What about Japan or Australia being close to the China's sphere of influence? Will America's allies have an air superior fighter that is competitive to their most potential enemies???

I thought for a minute, would a higher end F-35 (an F-35A fighter only variant) be a better solution than a low end F-22? Cut things from the "A" variant that are not needed for an air superior role. Then I realized the engines are designed for exceptional performance at a lower speed and lower altitude than the F-22, so it would not be an easy design change.

I think it is more than just engines that are optimised for certain altitude and speed but also things like wing design and inlet shape.
