    They just greenlit the F4, which will replace the Mirage 2000 C/D/N from 2025 and will be mostly an electronics and software mod focused on strike missions - including taking over the nuclear strike role.

    There are plans to start development of a "F5" (or whatever they will call it) that will basically be a Gen 4.5 aircraft with airframe modifications to embody LO supplanted heavily by a further upgraded SPECTRA ASC system. Realistically could be a possible starting point for a cooperative development. The German idea seems to be mostly a network-centric approach that could use such an airframe to host the necessary hub for data aggregation and target selection for accompanying UCAVs outfitted in a mission-specific modular fashion.

    When looking over sixth-generation concepts in the US i'm kinda missing basic development on some natural candidate electronics approaches btw. Airborne laser communications terminals for global data networking via DRS satellites for example. I mean, we've been working on that for a while, and it's likely we'll still see one even for Tornado still (beyond the prototype tests that have been done).

    Don't really need any new arrangements - i mean, the Dutch military is pretty much integrated these days...

    The electronics part is very hush hush in the us.

    For example the f35 has built in madl, which is a phased array based directional data link, but how that's achieved is not discussed publicly beyond the very basics.

    The get also has a satellite link, but that's not discussed also.

    The upgrade, which the company is calling the F135 Growth Option 1.0, could be cut into the existing production line by the early 2020s, said Matthew Bromberg, president of Pratt & Whitney military engines.

    Pratt & Whitney recently completed performance tests of an early version of the system, called the fuel burn reduction demonstrator engine, which proved that the upgrade could improve thrust by up to 10 percent and reduce fuel consumption by up to 6 percent, he said.

    “It’s very common, so we could drop this upgrade into any one of the three variants. It would be compliant with the partner requirements and go to foreign partner countries. It would be cost neutral, so the upgraded JSF motor with Growth Option 1.0 would be the same price as the existing motor.”
    More thrust and less fuel burn while remaining cost neutral? Cheers to the boys at P&W, this is the right way to try to keep a sole source contract.

    Who knows, maybe we'll see a supercruising F-35 one day.

    Oxygen system ground the USAF's F-35s?

    Wasn't this a source of problems allready?

    Its been a problem with a couple of airframes. F-35, F-22, F-18 and the T-45.

    Maybe we need to go "old School" and carry O2 onboard instead of generating it

    The old Hornets carry LOX onboard but have hypoxia incidents at similar rates to the Super Hornets using OBOGS. The issues with the F-22 were eventually traced to problems with the G-suit being too constricting rather than a lack of O2 being delivered or contamination of the air. Although not before installing an automatic backup system.

    Apparently there's no good way to measure the quality of air being delivered short of lots of bulky instrumentation that doesn't fit aboard a fighter, so tracing these issues down has been elusive across the services.

    To add further to the mystery so far only A and C models are affected even though B uses the same system.

    Diferent pipping/cabling because of the VTOL engines?... yeah, weird, I know but this is getting into that territory...

    You could be right. Hypoxia incidents seem to be real hard to pin down.
