They must know something we don't, and it's gotta be China as Russia continue to struggle matching technologies the US have had operational for a few decades now.

I thought the general consensus was that there weren't too many advantages to developing the NGAD platform currently? Engine tech could certainly give you some more range... it could be lighter. What else though?

I would expect a shape optimized more for speed and stealth like the YF-23 (or a complete delta even) without cruciform tails, but that'd hit the maneuvering performance hard. I personally don't believe in WVR engagements, but I can promise the internet would lose their minds talking about how it couldn't dogfight lol!

I don't see how the platform can excel at BVR / stealth / speed and retain stellar super-maneuverability. It's pretty much gotta go. The only exception would be to rely on 3D vectored thrust as principal attitude control versus supplemental.

Unfortunately we probably won't hear a peep about this thing till it's unveiled - I still can't believe the secrecy surrounding the B-21. I wonder if Northrop would get the contract?

Anything's possible, the B-2 still utilizes radar masking technology that's still considered classified. How old is that aircraft again?

It all sounds very expensive. In addition it may be that more than ac is required to maintain AS. I don’t suppose there’s any chance the west could coordinate and cooperate on this effort.

In addition to any US efforts it seems like there is at least two programs in Europe and possibly one in Korea and Japan so there is a good opportunity to spread rd money.

Obviously a new program model would be required but this is costly enough to warrant a look.

True, but the B2 is about the least maneuverable plane in history lol - zero vertical aerodynamic surfaces, it's nearly perfect as far as a stealth platform goes. This is simply impossible for anything like a fighter (or even anything supersonic, as it'll need stabilizing elements of some sort). I think the "Black Widow" was on the right track, but at the time, super-maneuverability was viewed as critical (which was probably the right call). Next time around, probably not so much.

Sorry I should have quoted more of your post - the B-2 comment was regards to technology to reduce an aircraft's radar signature. We've come a long way since then and I'm sure there will be some great things in the B-21 that'll give an IADS a run for its money (along with some additional capabilities on some demonstrators out in the desert).

Did you have a chance to check out the X-36 link? That's more in line with the stealth/super maneuverable aircraft part of your post I quoted.

Relevant regarding the rapid prototyping discussion:

Air Force OK With Failure on New Rapid Prototyping Acquisition Programs

The Air Force expects that some of the prototyping programs launched under its recently minted Section 804 fast-track procurement authority will fail—and it’s OK with that, a senior acquisition officer told AFA’s 2019 Air, Space & Cyber Conference Sept. 17.

“We’re going to have misqueues on Section 804, and that’s OK,” said Lt. Gen. Duke Richardson, the military deputy in the office of Air Force acquisition head Will Roper.

Indeed, Richardson said some degree of failure was to be welcomed. “I hope there are some that don’t work out, otherwise we’re probably not pushing the envelope hard enough,” he told a panel on industry partnerships.

Section 804 of the 2016 National Defense Authorization Act mandated the creation of new “middle tier” procurement authorities that would allow for rapid prototyping and fielding of new defense capabilities.

But the very nature of such programs, Richardson told Air Force Magazine after the event, mean that some weren’t going to succeed. “Because they’re prototypes, we don’t know ahead of time if they’re going to work,” he said.

What the service needs to avoid is “oversteering” and condemning the whole idea because some don’t work out, he said. “The important thing is to figure out why it failed and then learn from it, not just say ‘Well, I guess we shouldn’t do 804s anymore.’”

The authority was designed to allow new technology to get to the warfighter faster, but that also means accepting more risk, Richardson said, something that needs to be reflected in the way programs are managed. “We have a tendency to run the small programs just like the large ones and we shouldn’t do that, that doesn’t make sense. The financial risk is much lower to us” for a small program, he pointed out.

Recognizing that faster acquisition means greater risk also has implications for the way that personnel need to be incentivized, he added.

“Right now the workforce is very fairness based, which is fine, and very process based. And the reason they’re so processed based is because they don’t want to make a mistake because they don’t want to get hurt for it. And that’s what slows us down sometimes.”

Asked how the service could overcome this notorious risk aversion of its acquisition community, he replied, “Simple: By not shooting them” if they get it wrong.

Acquisition officials need to know that “As long as the program plan is solid and well executed with due diligence, they’re not going to get hurt,” career-wise, by failure, he said. “We have folks who’ve been promoted that have worked on programs that have been canceled. … I’ve worked on canceled programs and I’m still here,” he concluded.

Thanks for posting that, it definitely adds to the discussion. I agree the USAF is prepared to adjust its risk profile to match what it needs to do even though as expected the USAF itself acknowledges that it currently has a very high aversion to risk.

The question then is whether Congress and the public are also willing to accept that higher risk profile. The impression I get is that Congress potentially isn’t and from my following of the F-35 program is the general public, or perhaps more succinctly the press reporting to the public and marketing hysteria, is nearly rabidly against under performing, over budget or delayed programs.

The recent attacks on SA highlight how vulnerable infrastructure is.

For most countries and the more developed the more vulnerable, a few hundred to a few 1000 precision strikes would cripple the ability to defend itself w/o resorting to nuclear strikes.

The combination of LO and precision weapons have dramatically increased the importance of air superiority and the advent of uav’s will further up the ante.

It won’t be long that any fixed target including leadership targets will be at risk w/I weeks of any conflict.

I suspect we will see this play out in Israel and Lebanon with in a few years.

I don't think anyone wants to restrict the scope of the thread - I do however question the need for such an aircraft in the first place. The F-22 has been sitting around idle for over a decade with absolutely zero (deployed) aircraft to challenge it. I'd assume it's far enough ahead of the power curve with avionics and sensors/engines that this will continue for another decade. The F-35 (from a systems standpoint) is even more advanced.

It's cool for PR, but no one is going to be challenging US fighters head-on unless they have a death wish. The battlespace element / picture and data-sharing are another critical facet of this scenario, as (presumably) all US aircraft will have a complete and integrated battlespace picture of what's going on, and can task / allocate targets depending on visibility and weapons loadout accordingly. Developing that type of integrated network/communication is probably far more lethal than specific stealth or fighter technologies on their own.

You could very well be right that money is better spent elsewhere. My only point is that while the West has enjoyed air superiority since ww2 it will be more important than ever to so as air launched weapons are making step change improvements in lethality.

Well that's the problem here, I agree with that - however I don't see how air superiority will really impact the deterrence or threat mitigation of such weapons. At some point, you're just talking apples and oranges - and I think we're at parody now. Fighters will engage fighters, and fixed systems will engage missiles (ships have highly advanced anti-missile systems, same with ground-based installations).

There's no advantage that a so-called 6th gen fighter would bring to the table really. The kinematic performance of the F-22 is absolutely exceptional, I can't envision a missile which requires higher performance than what the F-22 could deliver. Most of these so-called hypersonic missiles will likely be deployed by conventional platforms like the B-52 anyways. Hell you could throw one in a B-1B and still achieve speed, with greater range than the F-22 even.

Familiar talking points to what is happening with Tempest and FCAS in looking at concepts and networks of systems. Interesting to note though that they aren’t planning to push through just yet but want to cement and advance the engineering processes and algorithm development.

The US Air Force is in no hurry to commit to a next-gen fighter design

The U.S. Air Force is taking its time to settle on a next-generation fighter design, awaiting instead lessons learned from the F-35 jet and playing the field with promising technologies, according to a senior service official.

Options being kicked around are still in the conceptual stage, as America’s newest fighter, the fifth-generation F-35, is only now “coming off the line,” according to Lt. Gen. David Nahom, the Air Force’s deputy chief of staff for plans and programs.

“We’re not in a hurry,” Nahom told Defense News on the sidelines of the International Fighter Conference, an air power-themed confab of industry and government officials held in Berlin, Germany. He noted that expected deliveries of the F-35 and the relatively young age of the F-22 fleet enables the service to be picky about moving forward with the envisioned Next Generation Air Dominance weapon.

In short, the Air Force wants to keep its options open for as long as possible for a weapon whose combat punch will lie not in a single aircraft but rather in the amalgamation of hardware and software, an airborne concerto of data clouds, artificial intelligence, and boundless interconnectivity.

“We don't want to get too stuck into a platform,” Nahom said. “It's a very different way to approach it.”

...

https://www.defensenews.com/global/euro ... er-design/

The article also has the following description of the difference in the goals for the American program compared to the European programs.
But Nahom noted a difference in the American way of thinking when it comes to piercing contested airspace — a key skill required of all future warplanes. While the Europeans seem to perceive the task as popping dispersed bubbles of ever-improving air defense systems, the U.S. view is that any airspace may be contested at any given time.

I saw your post in the other thread; the Advanced Medium Combat Aircraft looks very similar to the F-22. I know that the F-22 is out of production for good, but how straightforward would it be to turn the F-22 into a "6th gen" fighter? Most of the points don't seem to require an all-new airframe. Perhaps a new anti-radar coating. Sure, it would be a very major update (e. g. a new cockpit) but surely integrating new sensor fusion and control algorithms into an existing jet is easier than starting from a clean sheet.

To answer that we need to answer the question and reason I started this thread in the first place, what will be the defining factor of a 6th gen aircraft? Until we figure that out I’m not sure we can say whether 5th gen aircraft can make that jump.

If the significant change is perhaps autonomous operations then potentially so, I expect the sensor and sensor fusion present on 5th gen aircraft could be adapted to a 6th gen concept. Posters in this thread have suggested speed or persistence is the determining factor, in that case it is unlikely an F-22 or F-35 will be upgradable to 6th gen. If it is only sensors, or maybe Directed Energy Weapons, then it is a 50/50 but may require whole new electrical architectures to make that change.

So based on my comments above I think it is probably unlikely we will see a 6th gen conversion from 5th gen jets. Just as we have seen 4th gen go to 4.5 I think we will see 5th go to 5.5 and they incorporate some of the capability of a 6th gen platform but to take full advantage a 6th gen will probably require whole new airframe/engin/avionics/manufacuring technique etc.

If you consider it would be expected to have a higher performance engine than today, likely based around the AETP technology, new electrical architecture to handle DEW, perhaps different shaping or coating to handle be attacked by DEW, perhaps faster speed, longer range, greater processing power or communications to improve autonomous ops? All those point to an airframe that may look reasonably different to the delta variant winged fighters we see today.

In e.g. UK the Education budget is twice the Defense budget. In the US Defense budget is nearly 6x the Education budget. It is part of a deeply embedded culture / industry. Don't dare to question..



I am so tired of defense spending comparisons. These are vastly different economies. The US has the largest economy in the world. The price of all weapons systems produced in the US is sharply more expensive than those produced in China or Russia.
A Chinese PLAAF J-20 cost about $30MILLION, a USAF F-35A costs $85MILLION. Labor costs in the US are higher than Chinese labor. The same with Russia, the SU-57 costs $45MILLION and Russian labors costs are higher than China, but still below labor costs in the US.

The Chief of Staff of the Italian Air Force has some interesting comments and backs up what has bene said regarding 6th gen fighters, that the concept still hasn’t been defined.

Italian air chief: Time to think about next-gen fighters


...

The sixth generation has not been clearly defined yet, but we must think now about what we will need in 20 years. It could be artificial intelligence, direct-energy armament, or the possibility to integrate and direct swarms of drones from an asset acting as a sensor itself through its capability to adapt its own “skin.”

The biggest challenge will be for industry. The program will be a pulling factor for national industry for the development of future technologies that do not exist yet.

...

https://www.defensenews.com/outlook/201 ... -fighters/

To follow the above, if we separate the potential identified 6th gen capabilities already spoken about in the thread, are there any emerging technological sectors that people see changing fighter combat and being embraced by the 6th gen programs?

Will there be an advantage to being a later to market 6th gen aircraft, so perhaps is Tempest or FCAS are delayed by three to five years will that delay allow them to better integrate new technologies, or is the rapid integration of new technologies one of the defined characteristics?

I'm sure there are some capabilities that are classified at the moment that may more clearly define what a 6th gen fighter is. Some of the features you mentioned (swarms/DEW/AI) could be incorporated in a 5.5 gen manner.

It's a good possibility the next gen multi-role or air-superiority fighter will have a significantly longer range than what we have now, and dynamic engines to maximize efficiency in different operating environments. As for what the classified capabilities are that could be on the horizon? Who knows, only the dreamers out in the desert do.

Rapid integration of new technologies is the key for a 6th gen design. It will be largely a modular concept with a big focus on making avionics and systems upgrades easy.

Wait for congress to come up with alarming foreign "6th Gen" fighter threats soon. Dismissed / downplayed until yesterday, millions are invested spreading the news, highlighting probably Russia, Chinese air force aggression. Use new media, nationalism, Hollywood, Lexington Institute, incidents to get the perceptions in. In the interest of humanity, world peace, 2.1 million+ industry jobs and the $600billion defense budget.

Innovation will be key if the US Department of Defense wants to keep up in an ever-changing world. Awesome weapons will be ours :cloudnine: I feel more should be spend on Defense in the US. :cool2:

In e.g. UK the Education budget is twice the Defense budget. In the US Defense budget is nearly 6x the Education budget. It is part of a deeply embedded culture / industry. Don't dare to question..



I am so tired of defense spending comparisons. These are vastly different economies. The US has the largest economy in the world. The price of all weapons systems produced in the US is sharply more expensive than those produced in China or Russia.
A Chinese PLAAF J-20 cost about $30MILLION, a USAF F-35A costs $85MILLION. Labor costs in the US are higher than Chinese labor. The same with Russia, the SU-57 costs $45MILLION and Russian labors costs are higher than China, but still below labor costs in the US.


Labor costs ain’t everything. Belarus I’d wanting F-16s now since the SU-27 series is so expensive to keep operational. Specifically mentioned is how many sets of engines it eats. https://defence-blog.com/news/russian-s ... -f-16.html

So there is modular and there is modular. I don’t expect we will see modular airframe components. If significant VLO is required you simply can’t chop and change in that way. With respect to systems though, given virtualization now it should be highly possible to modularize that to the extend that nothing is locked in other than generic hardware. I listened to a podcast recently with David Deptula who suggested as such while discussing the USAF’s moves towards a digital century series (which is a term he didn’t like and is apparently encouraging USAF leaders to avoid using).

Question though is how far along F-35 will get to make modular a 5th gen standard and therefore not a defining characteristic of 6th gen platforms. F-35 already has a significant level of hardware abstraction and will only be improving and Blk4 changes are 80% software (no airframe mold line changes) with releases far more frequent than previous generations.
