... Another controversial quote!We still have to make it real and there’s a lot to do in the program, but when you see what is going on, and you hear it from the Airmen who are flying it, you get a chance to really understand where we’re going.

To me it sounds like flying it means a combination of the physical demonstrator and maybe something like the avionics are being developed on the catbird....

Variable cycle will optimise thrust relative to airspeed though, so you can effectively have a high BPR at low speeds and a lower one at high speeds. Material science also moves pretty fast with new alloys that allow higher TETs.Getting more thrust out of conventional turbo fans is likely reaching diminishing returns for skyrocketing costs.
sound like mods to existing turbofans ...molecules flow just so fast unless one starts inducing them w/EM or exotic fuels etc etc..toward hypersonic....Variable cycle will optimise thrust relative to airspeed though, so you can effectively have a high BPR at low speeds and a lower one at high speeds.

Higher TET allows a higher jet velocity and a higher intake velocity, not hypersonic though (nowhere near yet anyway). For hypersonic you can use a precooler with an inert gas and drive the turbine with that inert gas once heated by precooler, whilst you mix the air with fuel and ignite it before sending it straight out the nozzle, as per SABRE.sound like mods to existing turbofans ...molecules flow just so fast unless one starts inducing them w/EM or exotic fuels etc etc..toward hypersonic....Variable cycle will optimise thrust relative to airspeed though, so you can effectively have a high BPR at low speeds and a lower one at high speeds.

Agree, with current and constantly improving weapon accuracy, having a manned hypersonic fighter makes no sense.A hypersonic NGAD has to be the dumbest vehicle I've ever heard of, as it wouldn't have persistence, stealth, or maneuverability and I would have to wonder how well any sensors might work on it at those speeds. Even hypersonic missiles have issues with targeting. Now, maybe a limited set of hypersonic strike/long range interceptors that can use offboard targeting for enemy stealth bombers and long range prompt strike with a man-in-the-loop, I could see missions like that making some sense. But definitely not for NGAD.
As stated a yawn and absurd. FA-xx is different requirement. NGAD survivability requires the ultimate high ground, ultimate warning, ultimate stand-off ie near space. Air Dominance is to defend against ICBMs, IRBMS, Hypersonic cruise , Hypersonic Ballistic etc.Fairly basic information but good animation of the various 6G concepts uploaded here at SPF

“We have experienced performance issues on a classified fixed-price incentive fee contract that involves highly complex designs and systems integration at our aeronautics business segment,” Lockheed Martin says in a financial disclosure filed with the Securities and Exchange Commission on 26 July.

That is a recent thing, post 2000 outside of some NO FAIL programs.Aren't development contracts usually cost plus?
Navy CNO Gilday launched a thinly veiled attack on Boeing at SNA 2021 yesterday for lobbying Congress to fund more F-18s and keep the production line open whereas Gilday wants funding for a 6th Gen a/c, whether a F-14 replacement or attack a/c unknown.Well, considering navy's vision of replacing super hornets and compliment the f-35 fleet after 2020, I think air superiority will be a requirement.
There's also the fact that short and medium range AAMs will be carried on drones, in addition to the drones performing offboard sensing. So NGAD will probably be able to do those roles simultaneously.USN NGAD will almost certainly be a dual role aircraft mixing interdiction and interception. There’s really almost no reason not to combine the roles on a single long range platform given that air to ground or air to air mode is now literally abutton click for different radar and display modes. Basically what F-111 was originally intended to be.
