The F-22 program was truncated because it became too expensive.
No it was Truncated as at the time the Political mindset was it was a Cold War relic and F35 the strike fighter more matched the for of mission set being seen in combat of Iraq and Afghanistan. Where in the air to air capability was null to the ability to drop guided munitions. F35 at the time cost as much as F22.
@Jura loves to comment on F35 and F22 being used to drop bombs on bicycles. Well F22 wasn’t supposed to do that F35 has been almost tailored for doing that.
This was a period and is to some degree still where the Powers that be

The F-35 was on life support at one stage but the program recovered. The development cycles for both of these programs are approximately 14 years, In contrast it was 3 years for the F-16 and about 6 for the F-18. I think the USAF do not intend to repeat the same development pathway given recent history. My sense is the USAF is avoiding a platform centric approach by design and by default given a bunch of emerging technologies. The issue is how do you capture a bunch of new technologies without being held captive to a particular platform. A distributed approach is meant to hedge technological risk and to contain cost. Will it work? This is the part where there would be greater clarity once some kind of framework is made known. Until then we are just speculating
This is what I mean by changing the way we build these aircraft. F22 and F35 were built as a wholistic approach you design the aircraft and everything in it. For F22 and F35 as they exist now it was an absolute necessity.
However as time has progressed Raptors seem to be moving to a open architecture model not just in computers but potential add ons. This I think is how the next generation will start using more plug and play type mission equipment.
I think this statement needs to be tested and not just simply accepted as true. The question is what capabilities and more importantly how would future technologies change the equation. For example, it is generally considered that the F-22 is more maneuverable than the F-35. Will lasers change that equation? The F-22 can fly faster but IR signature becomes an issue.
Laser technology is still maturing However thus far its not ranging out to seventy KM but more like twenty to thirty. The power supply is a issue here the engine of a Jet is packing all the electrical power of the fighter. A twin engine is inherently going to offer more electrical power than a single engine of the same or similar class.
F22 does fly faster and with super cruise that doesn’t mean a larger IR signature. It’s the Reheat that drives up fuel and heat.
If there is a future platform I would bet that it would be essentially be a mini B-21
Why not? I believe a future dominant platform will not be built for speed or maneuverability. A mini B-21 will have the shaping for all aspect stealth; capacity for range, sufficient power for EW, ESM and EA for spectrum domination; internal bay sufficiency for long range hypersonic weapons; and lasers for WVR engagements.

It should be apparent right now B21 is not a quick development. We are still waiting to see it. It’s supposed to enter service in 2025 and the program got its wheels under it in 2016.
Farther more is the juice worth the squeeze for such? If the USAF was looking for a small strike bomber flying wing Northrop Grumman has that the X47B. B21 is not a fighter it’s a Very Low Observable bomber it’s meant to drop large bomb payloads and large missiles on target. Lasers are not a panacea. The power recharge rate, range and fact that other nations are working on them mean that their value is not such as to make up for the limitations of the flying platform they are in.
You brought it up before to. But lasers do not make a Strike fighter the dominate bird of the sky. They are a system to be integrated.
Missiles are increasing range and speed a slow speed large payload may be don’t for strikes but not air to air engagements you still need some ability to intercept and fight especially since the world is working on its own stealth platforms. J20, FC31 and SU57 mean that air superiority may mean closing range for a dogfight of some form. Having Uber turning rates like SU57 at the cost of low observable shaping doesn’t mean an advantage but it does mean it’s not an open and shut case. Bombers have a job and are better to that job. B21 will be impressive for its intended missions. But some jobs need a fighter.

A high low mix is as much a function of cost and the prevailing threats at a moment in time. In 20-50 years, that relationship may change simply because of technology. Theoretically, a mix and match approach provides greater flexibility and agility to meet emerging threats. That said, the LCS program did not work out very well
A high low mix is mix and match. I feel that what we will see is more an expansion of the support aspects of the fighter program rather than ditching the fighter concept for a manned mini bomber with lasers. Distributing support for the fighter wings.
Right now F22 and F35 have issues but a number of them are sourced to the environment around them.
Complaints about short range; they are real issues but before we could have a fighter dragged to the fight by a Tanker today Tankers and AEW are missile bullseyes in the sky. You cannot make a Fighter as large as bomber it wouldn’t be cost effective. You cannot give a Fighter a eco cruise efficient engine like those used on jet liners. It’s not survivable in combat.
You can make a more efficient fighter engine which is what we see finally happening. You can add external tanks like we see on Raptor’s sometimes and being added to F35A now, conformal tanks like the Israelis are working on for F35I. But these only aid in adding range. What is needed is a tanker that doesn’t light up every IADS radar for a thousand miles. Smaller and cheaper with a smaller RCS. A drone could do the job.
Complaints about Radar range, F22 and F35 have monster radars today but not theater wide radars. Using data links F22 and F35 can talk to each other sharing part of the picture but only to those able to listen. Clearly that still leaves potential gaps. E3 Sentry birds though light up missile networks like a Christmas tree as as proven the type of platforms they are built from are easy missile prey. Since we know that LPI air to air radars can be mounted in VLO platforms I ask why not build an AEW Flying wing drone with data links for both F22 and F35? The USAF has already been looking at taking the operators off E3.
F35 and F22 both have built in excellent electric warfare suites rivaling any previous or current E/A or EF jammer birds built. There low observable aspects are farther augmented by jamming. Stealth does have flaws generally it’s optimized to the X band as this is the band chosen almost universally for use as attack radar. Low frequency bands may “see” a stealth but it’s like how Mr Magoo sees a lion. A bland blur of something over there. Jamming i this range though may be needed though along with other bands and having more jammers up spoofing along side the manned fighters could farther break an enemy’s battle effectiveness.
They can also aid in creating gaps for other assets like Infantry transports, Bombers vs a competent air Defence perhaps even forcing back sea denial systems.
Small payload. This issue though I think is part of the existing weapons in inventory. Air to air load outs with large pre internal bay weapons that were designed for flying open air. Already work is started into more compact faster longer ranged missiles that would better fit in the current VLO and potential future ones.

While those reasons you mentioned did contribute overall to diminishing Congressional support of the program, the main underlying remain the same as every other program that entered into the spiral of death as a result of cost overrun. Air & Space Power Journal has an excellent piece on the F-22 acquisition program. The key points being :
Diminished congressional confidence in the Air Force’s ability to control program costs led to the FY 1998 cost caps. When those caps were originally set, near-unanimous consensus existed regarding projected developmental costs among the Office of the Secretary of Defense (OSD) Cost Analysis Improvement Group (CAIG), JET, Air Force, and CBO. All of them estimated the EMD cost at $18.7 billion and the total research, development, testing, and evaluation (RDT&E) cost at approximately $22.4 billion. Unanticipated technical problems that came to light a few years later prevented the four independent estimates from predicting the later cost overruns. By 2007 the cost of total RDT&E had ballooned to approximately $30.4 billion, about 36 percent more than the FY 1998 congressional limit and 56 percent more than planned at the beginning of EMD.
(Page 66, Air & Space Power Journal November-December 2012)

As production began to wind down, the Air Force could not convince Congress to raise total program funding, despite the exceptional performance demonstrated by the F-22. Figure 4 depicts how decreased production (after the 1997 QDR) offset increased developmental and production costs, keeping total outlay under the FY 1998 cap. In the end, the Air Force fielded just 25 percent of the F-22s originally planned and less than half of its long-standing requirement of 381. The service must consider this disparity between required and actual production
numbers in future acquisition programs.

There are two separate issues that you have raised and both are independent from the NGAD conversation. That said I will briefly comment on the issues you raised.
The reason why there is a fifth to fourth comm issue is because it is too expensive to install individual antenna onto 4th gen platforms. It is not a tech issue but one of cost. There are solutions. All that is required is a multi node gateway. I know it has been tested on a U-2s installed with EMC2 in one of the Red Flag type exercise. I am sure such a solution can be provided via a B2 platform or a RQ-180 drone should the need arise. Officially the USAF is not talking about it.

As to the AWACs, I am not sure whether it is technically feasible to operate a stealthy AWACs platform because it has to emit to perform its function.

I agree there is a need to expand jamming a wider frequency band. This is being addressed through the NGJ program. Separately there is speculation that the F-35 has the ability to jam beyond the x band. In any case, expanding the jamming capability is not platform dependent and can easily be implemented in future F-35 block upgrade should there be a need.

I don’t see them quite as independent but part of PCA as a whole although I am not sure quite that you got my point.

First communication between platforms is more and more critical especially fifth gen to fifth gen. Today F22 cannot talk to F35.
F22 uses the intraflight data link which sends LPI data from Raptor to Raptor. F35 uses MALD which does the same from Lightning to Lightning. They cannot talk across platforms though.
A common datalink needs to happen between F22,F35, F-X and other VLO operating in the theater. The ability to maintain communications of a non verbal manner is a absolute mission critical.
Since F35 is the most numerous of the two planned it makes sense to standardize on its system. Link 11 and Link 16 are often pointed to and can do the same except that they operate on known bandwidth so an enemy cannot read the messages but can intercept and track based on Link 16.
The advantage of a fifth gen is that you are combining data to operate as one well also being stealthy.
By beaming out the data picture from the radar and sensors from aircraft to aircraft you don’t need someone interpreting it. The Data is combined by your on board system into your displays. It is at the heart of what was started with F22 and completed with F35 and will form the basis of the NGF. This by the way is why I no longer use the term AWACS. As the C in that is no longer as relevant. 4.5 gens have taken on some of this same ability rendering the Command aspect superfluous.

F22 and F35 both Use an X band LPOI Radar. These are then clustered by data link. Expanding their range and power. In essence I am saying taking a uppowered version of that and flying it in a VLO drone with comparable data links but no independent attack ability.
If it is destroyed or targeted since it’s a drone it’s not as big a deal. In fact it still did it’s job of early warning and now other assets know that it’s a risk zone.

In the other aspect I was talking about more development of systems like the MALD-X that could be employed stand alone or as part of the VLO armaments or counter measures. In particular that was why I indicated use beyond just the fighter.
As we move ahead is seems like VLO is spreading beyond just bombers and fighters. Drones and ISR. I mean Neptune Spear proved that with the Stealth Hawk.

Having a Jammer buzzing the long wavelengths flying around on its own. It may take the form of a pod or a decoy or a drone or all of them (hows that for non Platform dependent?)

Looks like we are going full circle on this. In post #428, this is what I said " In a high end fight, the DOD's view is that it will be in three areas : space, communications, and battle management systems. NGAD is just a piece in the puzzle"

When I was referring to the subject of communications what I had in mind is that the systems portfolio approach will be highly dependent on secure communications link. Any adversary will clearly go after the communications infrastructure in order to degrade the effectiveness of the systems. The infrastructure required to build a robust network is so huge that the F-35 program in comparison is just small change. As an example; the cost to maintain a BACN node in Afghanistan cost more than a $Billion a year.

MADL operates in the Ka band and Link 16 in the UHF/L band. MADL is directional and Link 16 is omnidirectional

upload_2019-6-18_10-38-22.png
The reason MADL is LPI is because it is directional broadcast. The only way it can be intercepted is when an adversary happens to be positionally in between the direction of the emission. MADL has wide bandwidth and as such it has high throughput capacity. This means a MADL broadcast can be in short burst making interception difficult if not impossible. The drawback is it is short range. Estimate is between 20 to 100 nm as the actual distance is classified. A battle network will have to be built using some kind of daisy chain relay. Details on the MADL is classified and so we really don't know in practice how the DOD plans to address its range. It might be in the form of using a booster and using SAT com for distance.

Link 16 is widely in place but it has a small data pipe and will not work for CEC type of engagement as will be in any system of systems approach due primarily to latency issues. There was a study conducted on the different waveforms and the conclusion is even TTNT is not sufficiently stealthy enough. Currently the USN CEC is build around a TTNT data pipe. Each service is doing their own thing with communications infrastructure. .

Here's what the House passed for the Defenser bill. The Senate will pass their bill and it will need to be reconciled.

NGAD is a line item and it is, indeed, cut to $500M.

There's a lot more in there. Dig around, folks. Budgets are important. No bucks, no buck rogers.

"Michelle Evan, LockMarts head of "Aeronautics, I don't think you're going to see a "big leap" like you did from 4th generation to 5th generation, I think its going to be more an "evolution"!

BAH!, you're not going to see a "big leap" anywhere, because there is NO SIXTH GENERATION, ALL the aircraft that we currently see in development will be fortunate to measure up to the 5th Generation, I doubt we would even be able to call any of them 5+ with any degree of accuracy....

The F-22 was a quantum leap ahead, it remains the "alien bird", to be honest even the sweet little F-35 does NOT incorporate supercruise, while it is indeed very maneuverable, its not up to F-22, Su-35, Su-57 standards.

Remains to be seen, tbh. We don't know the requirements or capabilities of the European and Chinese projects. We don't even have a good definition of what the 6th gen even is at this point.

The US Navy's AOA is due by end of summer, but I'm leaning for its next gen to be a refined 5th gen, tbf.

That said, we can speculate what it will be and how it will differentiate the 5th and 6th gens, but all of it remains TBD.

maneuverability is non sequitur these days. The helmet sights and IR missiles will make any furball a mutual kill. That's only going to get worse with upcoming tech. What the F-22 and Su-35 (perhaps Su-57) can do probably won't show up in any future fighters, IMNSHO.

we shall see my young friend, actually I'm thinking your screen name should have been "Lazer MAN!", well I'm gonna be faithful to real life and remain a platform centrist man, you can't do much without a solid platform, you might end up with another F-117 which while performing admirably, proved to be far to narrowly focused to stay relevant in this dangerous new world.

as to your popular viewpoint that the days of the furball are over, The Gents in the USAF and Marine Corp, possibly to a lesser extent the USN, (yes they did found the fighter weapon's school) are still "doing the do", you'd have a hard time selling your maneuverability is a non-sequitur, so we will indeed watch history unfold.

Hope you are grilling something "tasty" on the Bar-B, a cousin from California told me it damn near impossible to get a good steak in Kali.... he's just North of Half Moon Bay... have a great day Bub!
