Si tratta di una nuova tecnologia per i fighter che presenta diversi vantaggi, tra cui la possibilità di operare in high-thrust mode per la massima potenza e in high-efficiency mode per un maggior risparmio di carburante.

Presenta anche elevati vantaggi nella gestione termica, una delle problematiche più importanti da affrontare su questi propulsori.

Secondo flightglobal.com l'Air Force sarebbe interessata al futuro impiego di un motore di tale categoria sul Lightning II ...
The USAF is interested in re-engining the Lockheed Martin F-35A stealth fighter with an adaptive engine to increase the aircraft’s 1,200nm (2,222km) range, which is viewed as too short for attacking targets within China.
The fighter currently is powered by the Pratt & Whitney F135 turbine engine.

NGAD ... il CSM dell'USAF afferma che sarà un caccia multiruolo ...
The Next-Generation Air Dominance (NGAD) system - the fighter that will succeed the F-22 - will have ground attack capability possibly for its own protection, Air Force Chief of Staff Gen. Charles Q. Brown Jr. told lawmakers June 16.
Testifying before the House Armed Services Committee on the fiscal 2022 budget request, Brown said he wants the NGAD to have “multirole” capability, emphasizing that the aircraft’s primary role will be air dominance but with the ability to strike ground targets as well.
Compared to the F-22, Brown said the NGAD will have “increased weapons load [and] … increased range” necessary to operate at the great distances required in the Indo-Pacific theater.
The NGAD will have “some air-to-ground capability to ensure, one, that it can survive, but also to provide options for our air component commanders and for the Joint Force,” Brown said, suggesting that the NGAD will be able to shoot at air defense systems that threaten it.

Dal sito di AW&ST ... un'opinione ...
Opinion: Key Questions About USAF’s NGAD Sixth-Gen Aircraft Program ...
Richard Aboulafia - August 19, 2021

It is increasingly clear that the U.S. Air Force’s Next-Generation Air Dominance (NGAD) sixth-generation combat aircraft program will be the next major military aircraft program.
There are two big unknowns:
Is there a flying aircraft, and who is the prime contractor?
And there are five secondary questions that also should be asked about the program.
First, last September, then-Air Force acquisition chief Will Roper revealed the existence of a full-scale prototype combat jet, in flight testing and “breaking records.”
This is purportedly part of NGAD, but given the evolving nature of the program - and given uncertainties about the maturity of this prototype - it isn’t clear how relevant this jet is to NGAD’s ultimate form.
But NGAD clearly is ramping up as a program, with $1.5 billion in R&D funding requested in fiscal 2022 (up from $902 million in fiscal 2021).
Second, we don’t know who built this prototype.
In its second-quarter results, Lockheed Martin took a $0.61 charge per share related to a classified program, and in its first-quarter results the company attributed a $135 million sales increase to classified contracts.
This month, the company opened a large new factory at its Skunk Works site.
Since classified reconnaissance aircraft are built in small numbers and seldom require large, new facilities, this plant may be connected to a new fighter.
But Boeing and Northrop Grumman are also likely competitors.

Beyond these uncertainties, there are five more questions about NGAD:

1. What is the timing?
Developing and integrating mission systems and other key components is a bigger challenge than building a test aircraft.
There might be a long gap between flying a prototype and producing an operational weapon.
Twelve years passed between the first flight of Lockheed Martin’s YF-22 and the first F-22 deliveries and almost 10 years elapsed between the X-35 and initial F-35 deliveries.
Digitalization may speed this process, but there is no clear evidence of this.
In fact, the pre-digital F-15 and F-16 saw just two and five years pass, respectively, between first flight and service entry.

2. How many will be procured?
Roper indicated that the service wanted a Digital Century Series approach, with relatively small procurement batches of multiple aircraft developed in succession.
But the procurement number is dependent on the timing: If it takes a decade (and the usual tens of billions of dollars in nonrecurring funding) to produce an operational fighter, then buying small numbers would be incredibly inefficient.
Also, as the saying goes, the enemy gets a vote here, too.
If conflict with a peer adversary is deemed a short- or midterm risk, then focusing on the current production model makes a lot more sense than waiting years for the next thing or series of things.

3. How joint is it?
The Navy’s F/A-XX program would seem to be somewhat behind NGAD in definition and funding.
But history indicates that there is little hope of a navalized NGAD aircraft meeting this requirement.
The Joint Strike Fighter is more of an Air Force/Marine Corps fighter; the Navy refuses to budget for more than tiny numbers of F-35Cs.
For the F-14, F-15, F-16, F/A-18 and F-22, “jointness” failed altogether.
It has been half a century since a U.S. fighter program was truly joint, with the McDonnell F-4 - and the Air Force was not so enthusiastic about it.

4. How global is it?
The F-35 has more than a dozen foreign customers; the F-22 had none, for political and cost reasons.
The F-15 might provide a good baseline for high-end fighter exports, if NGAD stays in production long enough to attract international interest - there are six international Eagle customers.
One was Japan, which might also find NGAD coproduction attractive as an alternative to its indigenous F-3 stealth fighter program.

5. What gets hurt when procurement starts?
Ramping up NGAD procurement cash would inevitably affect U.S. Air Force F-35A and/or F-15EX funding.
Since the latter is an older airframe, and since it is being procured at a much lower rate, NGAD could lead to F-15EX program termination.
Also, Air Force Chief of Staff Gen. Charles Q. Brown recently stated that the F-22 will be retired, leaving the F-35A, F-15 and F-16 and, of course NGAD.

In addition to these program questions, another great unknown concerns the new fighter’s capabilities.
Specifically, what will deployment of this aircraft mean for the balance of power, particularly against China?
Will NGAD’s manned-unmanned teaming capabilities redress the quantitative imbalance in the Western Pacific?
The answer to this is years away, but it is crucial to the strategic future of the U.S.

The views expressed are not necessarily those of Aviation Week.

Parole, parole, parole ... 🎶🎶🎶
Using new digital methods to design a future Air Force fighter costs more than the traditional approach, but subsequent iterations could be done faster and less expensively, senior Air Force officials said Sept. 22.
They also cautioned that the “Digital Century Series” is not synonymous with the Next Generation Air Dominance program and that no decision has been made about whether to take the approach on an NGAD successor.
The results of the Air Force’s business case analysis of the Digital Century Series approach to combat aircraft design differs from that developed by the Pentagon’s Cost Analysis and Program Evaluation shop, top uniformed USAF acquisition official Lt. Gen. Duke Z. Richardson told reporters Sept. 22.
The CAPE’s numbers were higher than the Air Force’s but were highly subjective anyway, he said, because assumptions play a central role in defining costs.
“The differences … are in assumptions about [operations and sustainment] costs, and O&S cost avoidance,” Richardson said.
“Another one is in the area of O&S cost growth; in other words, how much you project … the sustainment costs [will be], including manpower. The third area would be the time period of analysis.”
The results of any business case analysis are “really sensitive to those assumptions,” he added, and “the assumptions are hard to make; … where do you stop? A traditional program might be on a 30-year-plus cycle, whereas the Digital Century Series system might be on a 16-year cycle. So these are multiples of each other.”

L'estrema necessità di mantenere una solida supremazia aerea ...
The U.S. is in real peril of losing a potential war with China if the Air Force cannot shed obsolete gear and rapidly regain a solid advantage in control of the air, Air Combat Command’s Gen. Mark D. Kelly told attendees at AFA’s Air, Space & Cyber conference.
“We have to focus our fighter force to the basic realities of a new threat environment,” Kelly said in his ASC21 speech.
“And that requires the fighter force to change to be successful.”
Kelly said the joint force “requires air superiority” and doesn’t know how to fight or function without it - so this mission area should get priority for resources.
Kelly explained the the “four-plus-one” concept for the future fighter force - an improved F-22, making a “hot handover” to the Next Generation Air Dominance circa 2030; the F-35 as the “cornerstone” of the fleet; the F-15E and F-15EX as “big weapon” carriers; F-16s to provide capacity, especially in lower-end conflicts; and the A-10 as the “plus one,” with a fleet of 218 airplanes for close air support that sunsets in the early 2030s.

Intanto ... qualcosa di molto particolare è stato visto nel Deserto del Mojave ...
An apparently previously unseen low-observable aircraft test shape has emerged, with initial open-source intelligence research indicating it was spotted at Lockheed Martin’s secretive Helendale radar-cross section (RCS) measurement facility.
This site, located in the Mojave Desert not far from the company’s Skunk Works headquarters at Plant 42 in Palmdale, California, is among the most sophisticated of its kind and has played a key role in the development of U.S. stealth aircraft since the early 1980s.
While we don’t know what this shape is intended to resemble, it provides a timely reminder of some of the exotic test work that’s clearly going on behind closed doors, at facilities like Helendale and others, on a number of advanced combat jet development programs that we know about, as well as more stealthy aviation work going on in the classified realm.
A short video showing the apparent test shape seems to have been first posted to the TikTok video-sharing social networking service, before being shared on other social media channels.
Ruben Hofs brought it to our attention on Twitter.
--- --- ---
Intriguingly, the test shape does seem to show some broad similarities with various next-generation fighter designs, including some concepts for Next Generation Air Dominance (NGAD), that we have seen to date.

NGAD ... massima priorità dell'Air Combat Command ...
The Next-Generation Air Dominance Fighter is Air Combat Command’s top priority, because without it, the Air Force can’t provide the control of the air the whole military depends on to operate, Air Combat Command chief Gen. Mark D. Kelly said.
He also named a replacement for the E-3 AWACS, new weapons, and command and control improvements among the command’s top needs.
Speaking at a Mitchell Institute for Aerospace Studies virtual event, Kelly said NGAD is his No. 1 requirement.
He described it as a sixth-generation air superiority system able to operate at long ranges - farther than would be encountered in the European theater.
Kelly said NGAD is “designed to operate beyond a single spectral band of the RF [radio frequency] spectrum, to thrive in a multispectral environment,” and it also “senses” the battle space and “connects” the rest of the force, so “that I can put [it] in the adversary’s back yard.”
The NGAD is really a multi-service requirement because the other services are “not remotely - remotely - designed to operate without” control of the air, Kelly noted.
“Everyone’s counting on the Air Force to provide that.”

Da un noto ex-settimanale britannico ...
Emergono nuove informazioni ...
US Air Force to advance stealthy successor for F-22 ...
By Garrett Reim - 23 December 2021

The US Air Force’s (USAF’s) Next-Generation Air Dominance (NGAD) fighter remains under wraps, but some clues about capabilities the service wants in the aircraft are surfacing.
The sixth-generation fighter aircraft (one full-scale flight demonstrator secretly flew for the first time in 2020) is expected to replace the service’s Lockheed Martin F-22 Raptor fleet, starting in the 2030s.
Whereas past generations of fighter aircraft relied upon speed and manoeuvrability to defeat foes, it seems the NGAD will lean heavily on stealth characteristics to hide from opponents and on computing power to outsmart them, according to comments from the USAF and likely development partners.
Disclosures point to a hyper-connected stealth aircraft that will use artificial intelligence programs to rapidly digest and make sense of multiple streams of sensor data – information that will help combat pilots beat their adversaries to the punch.
NGAD will be a multi-role combat aircraft, but air dominance will be its primary mission, General Charles Brown, USAF chief of staff, told the US House Armed Services Committee in June.
He added that the service wants the aircraft to have an increased weapons load and increased range.
Greater range would be useful flying across the vast areas of the Indo-Pacific region, Brown said.
Greater weapons load would probably be needed in combat against China’s air force, which the Pentagon expects to have a numerical advantage.
Winning air battles will require more than a bigger arsenal of missiles.
In order to eliminate China’s numerical advantage, each fighter will have to be able to repeatedly find enemy aircraft and fire quickly – again and again.
Lockheed, a leading contender to develop the sixth-generation fighter, says new digital technologies will give NGAD “omniscient situational awareness”.
That is reminiscent of the “quarterback” role the USAF has given the Lockheed F-35 stealth fighter.
That aircraft is increasingly valued by the service for its ability to use its sensors, software and connectivity to survey the battlefield.

BIG DATA ...

An all-knowing capability also fits into the USAF’s desire for an Advanced Battle Management System (ABMS), a battlefield network that would allow pilots to make decisions faster using data gathered from around the combat theatre.
For example, ABMS might be used to pass intelligence, surveillance and reconnaissance information gathered by autonomous loyal wingman unmanned air vehicles (UAVs) back to the NGAD platform, which could then use artificial intelligence programs to make sense of it all.
The USAF has described NGAD as being a “family of systems” with the manned fighter at its centre.
In October, the USAF awarded Kratos Defense & Security Solutions and General Atomics Aeronautical Systems each a contract to develop an “Off Board Sensing Station” UAV.
Such a loyal wingman would probably fly in advance of NGAD, search for targets and threats using its sensors, such as radar and infrared search-and-track sensors, and then possibly act as a weapons launch platform.
Raytheon, a manufacturer of advanced radars, expects sensors on NGAD to be automatically “harmonised” to find targets.
Some sensors, such as radar, might also be automatically turned off in certain situations to reduce the jet’s electronic signature to avoid detection, the company says.

ADVANCED ADVERSARIES ...

Interest in artificial intelligence partly comes from a belief that the future battlefield is going to be overwhelmingly chaotic and complex – challenging circumstances created by large numbers of sophisticated radars, electronic warfare systems, surface-to-air missiles, and fighter aircraft fielded by advanced adversaries such as China and Russia.
“It’s going to take a suite of sensors integrated together,” says Eric Ditmars, vice-president of secure sensor solutions, Raytheon Intelligence & Space.
“There are environments where the radar performs phenomenally,” he says.
“There are environments where the radar is jammed, where infrared search-and-track systems are phenomenal.”
Integrated systems must be able to respond to changing circumstances.
“The environments are getting so contested that you really have to have the ability to be more adaptive,” says Ditmars.
“The intent is to allow that pilot to be able to be more flexible in the mission that they are executing, and not be as reliant upon the pre-planning that has been done.”
Being able to rapidly call upon the right sensors could make or break a mission, especially when unexpected threats pop up, he says.
It is a concept that goes past the sensor fusion techniques employed aboard the F-35, Ditmars says.
Potential scenarios might be solved ahead of time by training artificial intelligence (AI) programs using computer simulations of combat, he says.
“That’s the great thing about artificial intelligence. You give it a set of defined criteria and it figures it out,” Ditmars says.
The concept has a precedent.
Researchers with Air Combat Command recently developed the ARTUµ software, a machine learning program that used more than half a million computer simulations to train the radar on the Lockheed U-2 surveillance aircraft to find enemy missile launchers.
In late 2020, the artificial intelligence program was demonstrated aboard a U-2 at Beale AFB in California.
“ARTUµ was responsible for sensor employment and tactical navigation, while the pilot flew the aircraft and co-ordinated with the AI on sensor operation,” explained the service.
“Together, they flew a reconnaissance mission during a simulated missile strike. ARTUµ’s primary responsibility was finding enemy launchers while the pilot was on the lookout for threatening aircraft, both sharing the U-2’s radar.”

NEW TEAM ...

The USAF said the AI software was “easily transferable” to other systems, and that it planned to refine the technology.
“Putting AI safely in command of a US military system for the first time ushers in a new age of human-machine teaming and algorithmic competition,” said Will Roper, who was assistant secretary of the USAF for acquisition, technology and logistics at the time.
“Failing to realise AI’s full potential will mean ceding decision advantage to our adversaries.”
In other words, asking a pilot to make sense of complex sensor data in the middle of a pitched battle might lose precious seconds to the enemy.
“We’re trying to take some of this workload off the pilot. They are human and they can only do so much,” Ditmars says.
“As the systems get more and more complex, it becomes very challenging for them.”

NGAD ... il Segretario dell'Air Force Frank Kendall parla di costi da capogiro #-o ...
The manned fighter aircraft that will form the centerpiece of the Air Force’s Next Generation Air Dominance program will cost hundreds of millions of dollars per plane, Air Force Secretary Frank Kendall told members of Congress on April 27—but the service can reduce costs in development and sustainment.
Speaking before the House Armed Services Committee on the fiscal 2023 budget request, Kendall specified that the main NGAD fighter would cost “multiple hundreds of millions of dollars … on an individual basis,” acknowledging that such a price tag “is a number that’s going to get your attention.”
By comparison, the F-22 cost roughly $135 million per tail, making it the most expensive fighter the U.S. Air Force has ever developed.
The F-35A, meanwhile, costs around $80 million per jet, but that number could rise.
NGAD, according to Kendall’s estimate, will dwarf those costs, at least when it comes to price per plane.
But the sixth-generation platform will fulfill a key air dominance role, Kendall noted.

Rapporto al Congresso sul programma "Next-Generation Air Dominance" (NGAD) dell'USAF ...
According to the Air Force, the Next-Generation Air Dominance (NGAD) program is intended to develop “a portfolio of technologies enabling air superiority.”
The Air Force intends for NGAD to replace the F-22 fighter jet beginning in 2030, possibly including a combination of crewed and uncrewed aircraft, with other systems and sensors.
NGAD began as a Defense Advanced Research Projects Agency project.
Since 2015, Congress has appropriated approximately $4.2 billion for NGAD.
NGAD is a classified aircraft development program, but the Air Force has released a few details.
On September 15, 2020, then-U.S. Air Force acquisition executive Dr. Will Roper announced that the Air Force had flown a full-scale flight demonstrator as part of the NGAD program.
Secretary of the Air Force Frank Kendall announced on June 1, 2022 that NGAD program technologies have matured enough to allow the program to move to the engineering, manufacture, and design phase of development.

Da AW&ST ... un'opinione ...
Opinion: How The F-111 Sets A Precedent For NGAD ...
By Richard Aboulafia - June 28, 2022

U.S. Air Force Secretary Frank Kendall announced in June that the service’s Next-Generation Air Dominance program has entered engineering and manufacturing development.
This transition from the prototype phase is a crucial step and a surprise, since the schedule remains classified - like almost everything about the program.
But based on what we do know, we have seen this movie before.
The Next-Generation Air Dominance (NGAD) long-range combat aircraft is new, large and expensive, leveraging advanced technologies to satisfy an Air Force requirement.
That also describes the General Dynamics F-111, developed in the 1960s under the TFX program.
The F-111 story may help predict NGAD’s future.
First, NGAD’s price may make it vulnerable.
In May, Kendall said it would cost “multiple hundreds of millions of dollars” per airplane, a very worrying figure, putting it between the $130 million Lockheed Martin F-22 and the $600 million Northrop Grumman B-21.
As with the F-111, the price inevitably will be higher than expected, the consequence of the Air Force getting all the range and capacity it really wants (coupled with stealth, of course).
The F-111 provides an unpleasant precedent.
Program unit costs (including development) went from $3.97 million to a final $15.01 million.
That increase was accompanied by a procurement plan collapse from 1,388 jets to just 466, a near death spiral.
These pre-inflation values sound quaint today, but the massive price increase almost led to the program’s cancellation.
Fortunately for the F-111, the strategic environment did not change much during its development.
The threat, requirement and defense budget remained in place, so the program survived, barely.
The strategic driver behind NGAD - the rise of China as a possible peer adversary - is unlikely to change, but it could.
This would derail NGAD in much the same way that the Northrop Grumman B-2, F-22 and other single-service programs were stopped by the end of the Cold War after procurement of a small fraction of the planned buy.
Second, the F-111’s optimization for one service and the associated high price killed hopes for a bigger customer base.
The Navy considered the F-111B for carrier operations but went with the smaller Grumman F-14 instead.
The UK Royal Air Force hoped to buy 50 but cancelled its order.
In the end, the only export sale was 28 aircraft to Australia.
With NGAD, this will likely repeat itself: very few countries will have the requirement or financial resources to afford an aicraft in this class, especially since the key possible markets (Australia and Japan) will have just made budget-breaking investments to buy Lockheed Martin F-35s.
A U.S. Navy NGAD variant likely will follow the F-111B to cancellation due to cost, size and other factors.
Even the Air Force will not be able to afford as many as it wants, complicating legacy replacement and force structure plans.
Third, there is the technology question.
The F-111 was the first production aircraft to use variable-geometry (“swing”) wings.
NGAD may be the first production aircraft to use variable-bypass Adaptive Engine Transition Program (AETP) engines.
Both of these technologies are a way of reconciling speed and range.
While NGAD will offer other features to improve range, the AETP likely will be the best way to exceed the persistent 600-nm combat radius limit on USAF fighters.
Yet those swing wings contributed heavily to the F-111’s technical problems and cost overruns.
It has been over 40 years since any new design used them, and when the last Panavia Tornado and Rockwell B-1 are retired in a few years, swing wings will be remembered as an interesting experiment that was not worth the cost, complexity, weight and maintenance expense.
While AETP engines are quite promising and offer more than just additional range, there is no guarantee that they will not result in the same outcome.
That’s another program risk.
Despite these concerns, the F-111 story also offers hope.
It was not much of a tactical fighter, but with its large airframe, the F-111 proved adaptable to a wide variety of other USAF missions.
An additional 76 FB-111 bomber variants were built, and 42 of the fighters were rebuilt as EF-111 electronic attack models.
In 1985, strategist Edward Luttwak opined in 'The Pentagon and the Art of War', “today, some 20 years after the controversy, the F-111 . . . remains the most valued of all Air Force aircraft.”
The Royal Australian Air Force did not retire its F-111s until 2010.
With its F-35A and Boeing F/A-18E/F/G force, Australia no longer has anything like the F-111’s range and payload.
In other words, NGAD development may be risky and extremely costly, but if the F-111 is any guide, it will be a successful enhancement to the U.S. arsenal.

Assegnati nuovi contratti ...
The Air Force’s propulsion program tasked with producing engines for the Next Generation Air Dominance fighter awarded contracts to a mix of both engine-makers and aircraft-builders Aug. 19 (*), hinting that integration could be a priority in the prototyping process.
Boeing, GE Aviation, Lockheed Martin, Northrop Grumman, and Pratt & Whitney all received indefinite-delivery, indefinite-quantity contracts with a ceiling of $975 million for the prototyping phase of the Next Generation Adaptive Propulsion program.
As part of the contracts, those companies will focus on “technology maturation and risk reduction activities through design, analysis, rig testing, prototype engine testing, and weapon system integration,” the award states, with work expected to last until July 2032.

Viaggio in Giappone ...
The head of the Italian Air Force will travel to Japan next month to hold talks with his Japanese counterpart about collaboration on sixth-generation fighter technology.
General Luca Goretti said the visit would be a chance to explore what ambitions Rome and Tokyo share for next-generation fighters and what technologies can and cannot be shared by the nations.
“In October I have been invited to Japan by the head of the Japanese air force to discuss common programs - it will be the opportunity to share our vision and common point of view,” said Goretti in an interview with Defense News.
Italy partners with the U.K. on the Tempest fighter program while Japan is pursuing its F-X program to build a replacement for the Mitsubishi F-2.

Frank Kendall fa un passo indietro :scratch: ...
The Air Force’s secretive next-generation fighter platform is still in the design process, and has not formally entered its engineering, manufacturing and development stage, Secretary Frank Kendall said this month.
The acknowledgment marks a step back from June, when Kendall publicly said the highly classified Next Generation Air Dominance program had already hit the key milestone.
“We have now started on the EMD program to do the development aircraft that we’re going to take into production,” Kendall said at a Heritage Foundation event at the time.
It also has some experts wondering if the service can meet its goal of delivering the first iterations of the sixth-generation fighter by the end of this decade.
Kendall offered the fullest update so far on the status of NGAD during a Sept. 19 roundtable with reporters at the Air & Space Forces Association’s Air, Space & Cyber conference ...

Una "patch" molto particolare :scratch: ...
What is the “Voodoo II”?
And why does the Voodoo II project’s special patch say “Two-0-Thunder”?
The answers to those questions may reveal something about Boeing Phantom Works’ approach to the Next Generation Air Dominance (NGAD) program.
Alternatively, the patch could simply be the artifact of a one-off project, one of presumably dozens undertaken each year by the rapid prototyping and advanced concepts arm of Boeing’s defense and space business.

The first iterations of Collaborative Combat Aircraft, the drones that will pair with manned platforms, will join the Air Force’s fighter fleet in “the later 2020s,” several years before the Next-Generation Air Dominance fighter, service acquisition chief Andrew Hunter told the House Armed Services tactical aviation panel on March 29.
Hunter also emphasized that CCAs will augment all types of tactical aircraft, not just the NGAD system.

Una sola azienda sarà scelta, il prossimo anno, come progettista e sviluppatrice generale del caccia con equipaggio Next Generation Air Dominance (NGAD), nonostante anni di lavoro su prototipi e su numerosi progetti da parte di diverse altre aziende, ha dichiarato il 22 Maggio il Segretario dell'Aeronautica Frank Kendall.
Kendall ha aggiunto che ci sarà una competizione continua per fornire i sistemi al NGAD dopo che sarà stato scelto un vincitore assoluto, ma ha anche rivelato che il concetto originale NGAD, con competizioni a rotazione in grado di produrre una serie di piattaforme sempre migliori, è troppo costoso.
“Non faremo due NGAD. Ne faremo solo uno ", ha affermato Kendall in occasione di una riunione del Defense Writers Group a Washington.

Senza coda e invisibile ai radar ...
In occasione dell’ottantesimo anniversario della nascita della Skunk Works, divisione che si occupa di ricerca e sviluppo per i progetti più “avanzati” dell’aeronautica, la Lockheed Martin ha deciso di condividere sul proprio profilo Instagram delle immagini estremamente interessanti.
Attirando immediatamente l’attenzione di analisti e appassionati di aerei militari di tutto il mondo.
Stiamo parlando di tre sagome, dai tratti estremamente semplici su sfondo nero, che mostravano il profilo di un nuovo misterioso velivolo di prossima generazione: con buon probabilità il caccia di sesta generazione che andrà a sostituire il caccia da superiorità aerea F-22 Raptor, secondo quanto previsto dal programma Next Generation Air Dominance.

Northrop Grumman non competerà per essere l'appaltatore principale del programma ipersegreto del caccia "Next-Generation Air Dominance" (NGAD), ma non ha escluso un'offerta per il corrispondente programma "F/A-XX" dell'US Navy o per il programma "Collaborative Combat Aircraft" (CCA) dell'USAF, ha dichiarato, il 27 Luglio scorso, Kathy Warden (*), Amministratrice Delegata di Northrop Grumman, in una chiamata sui risultati finanziari del secondo trimestre.
"Abbiamo notificato all'USAF che non abbiamo intenzione di rispondere alla RFP (Request For Proposals) per il programma "NGAD" come appaltatore principale", ha detto Warden.
Tuttavia, non ha escluso di essere partner o fornitore di altre aziende che presenteranno offerte nell'ambito del programma "NGAD".

Il futuro programma di caccia costituisce un test chiave per il metodo di progettazione dell’USAF ...
La futuristica piattaforma da caccia Next Generation Air Dominance, attualmente in lavorazione, sarà probabilmente una delle acquisizioni di armi più complesse e con la posta in gioco più alta nella storia dell’USAF.
Si prevede che l’aereo da caccia di sesta generazione includa nuove tecnologie che vanno dai motori adattivi all’avanguardia a un drone autonomo che vola al fianco delle sue ali.
Se l’NGAD funziona come spera l'USAF, potrebbe rivelarsi fondamentale in una potenziale guerra contro la Cina.
Ma negli ultimi anni le tecniche avanzate di ingegneria digitale, che l’USAF una volta pensava avrebbero portato a una rivoluzione nello sviluppo e nella messa in campo rapidi dei velivoli, non hanno sempre funzionato.
Il concetto consente agli ingegneri di creare progetti o modelli per testare le ipotesi in modo più rapido e preciso.
E poiché si prevede che l’ingegneria digitale svolgerà un ruolo centrale nello sforzo del NGAD, gli esperti affermano che l'USAF dovrà garantire che la tecnica sia all’altezza delle sue promesse.

C'era un programma segreto e multi-agenzia "X-Plane", vòlto a esplorare i futuri caccia, che ha aperto la strada al programma "Next-Generation Air Dominance", questo ha rivelato il Segretario per l'Aeronautica Frank Kendall al vertice sulla difesa "POLITICO" del 14 Novembre scorso.
Sebbene Kendall e altri funzionari dell'USAF abbiano in precedenza affermato che esistevano prototipi volanti prima dell'attuale fase del programma "NGAD", le sue nuove osservazioni hanno fornito maggiori dettagli sul progetto altamente classificato, comprese le agenzie coinvolte, parte del denaro speso e il fatto che "NGAD" controllerà i caccia senza equipaggio che lo scorteranno.
Ha anche osservato che il programma "Collaborative Combat Aircraft" senza equipaggio non verrà avviato fino all’approvazione del Disegno di Legge Fiscale sulla Difesa del 2024.
