GE Aviation and Pratt & Whitney are scheduled to complete separate competitive designs for a Next-Generation Adaptive Propulsion (NGAP) system by the second quarter of 2022 and finish assessments on a full-scale engine three years later, according to Air Force budget documents.
The schedule and spending details on the NGAP appeared for the first time in the Air Force’s budget justification documents for fiscal 2021 that were submitted to Congress in February, but passed unnoticed for several months. The Air Force awarded GE and Pratt each a $427 million contract to support the NGAP program, but the details were shrouded in budget documents within the related Adaptive Engine Transition Program (AETP), an unclassified effort to develop a reengining candidate for the Lockheed F-35.

Funding for the NGAD and NGAP programs is accounted for separately in Air Force budget documents. The fiscal 2021 budget justification documents reveal that the Air Force spent $106 million for the NGAP in fiscal 2019. Another $224 million is allocated to the NGAP this year. But the program has requested an additional $403 million in fiscal 2021, the budget documents show.
“The Next-Generation Adaptive Propulsion effort consists of four phases: preliminary design, detailed design, engine fabrication and engine assessments,” the Air Force’s budget documents state.

WASHINGTON — The U.S. Air Force has secretly designed, built and flown at least one prototype of its enigmatic next-generation fighter jet, the service’s top acquisition official confirmed to Defense News on Sept. 14.
...
"We've already built and flown a full-scale flight demonstrator in the real world, and we broke records in doing it," Will Roper told Defense News in an exclusive interview ahead of the Air Force Association’s Air, Space and Cyber Conference. "We are ready to go and build the next-generation aircraft in a way that has never happened before."
Almost every detail about the aircraft itself will remain a mystery due to the classification of the Next Generation Air Dominance program, the Air Force's effort for fielding a family of connected air warfare systems that could include fighters, drones and other networked platforms in space or the cyber realm.
...
The program itself has the potential to radically shake up the defense industry. Should the Air Force move to buy NGAD in the near term, it will be adding a challenger to the F-35 and F-15EX programs, potentially putting those programs at risk.

Si toda este sistema constructivo, que no es ni mas ni menos que una evolución del pensado para el F-35 y que resultó que estaba bastante verde, ya parece haber alcanzado su madurez, como el desarrollo rapidísimo del T-7 de Boeing y Saab parece probar, hay que irse a por el de cabeza. Porque solo se ven ventajas...
Si el FCAS llegara en el 2035 en vez del 2040, por ponerme en el mismo plan que los perfidos, pues por ejemplo perder el culo por adquirir un pequeño lote de F-35 no tendría sentido ninguno.
Mas que centrarse en todo el avión y su ecosistema que parece que va a flotar alrededor del FCAS, mas les valdría en enfocarse en lo de los yankis. Tener listo el chisme cuanto antes mejor y con tecnologías probadas. Y luego ya si eso, con la casa construida, nos dedicaremos a amueblarla con domotica y estilo feng shui, o como carajo se escriba...

Prototypes and demonstrations that develop technology surprise
While mitigating current threats and developing affordable systems are important, we are also asked to develop new systems that provide a leap-ahead technology. Under Secretary of Defense for Acquisition, Technology and Logistics Frank Kendall has initiated a new Aerospace Innovation Initiative (AII) to ensure that the United States can maintain air dominance in future contested environments. The AII includes a new program to demonstrate advanced aircraft technologies in X-planes (AII-X) as well as the on-going and previously mentioned Advanced Engine Technology Program (AETP). AII’s goals include strengthening the critically important design teams in the defense industrial base and reducing the lead time for future systems.
DARPA will lead AII as a DARPA/Air Force/Navy program to develop and demonstrate technologies enabling cost-effective air warfare capabilities necessary to defeat future near-peer threats. This program will develop and fly two X-plane prototypes that demonstrate advanced technologies for future aircraft. Teams will compete to produce the X-plane prototypes, one focused on future Navy operational capabilities and the other on future Air Force operational capabilities. The X-planes will not be Engineering, Manufacturing and Development prototypes or have residual operational capabilities. The result of a successful development and demonstration X-plane program will inform future aircraft system acquisitions.
The AII effort builds on the recently completed Air Dominance Initiative (ADI) study. In this effort, DARPA worked closely with the Air Force and Navy to convene leading warfighter and technology experts for a fresh look at what will be needed to extend U.S. air dominance in the face of fast-moving potential adversary capabilities. This group determined that no single new technology or platform could deter and defeat the sophisticated and numerous adversary systems under development. Instead, future U.S. capabilities will build on an integrated system of ISR, weapons, communications, electronic warfare, cyber, and other advanced technologies. We are excited about the probability that AII offers in demonstrating new capabilities through prototypes.

la USAF ya ha construido y volado un prototipo de su 6ª generación

Está claro que de manera secreta empezaron a desarrollar la sexta generación mucho antes de cuando lo supimos públicamente en 2012/13 y por aquí lo pusimos. De todos modos respecto a lo que comentabais luego, están diciendo en 2020 que han volado el demostrador, y el FCAS pretende volar su demostrador en 2026. Ya veremos si se logra, pero en todo caso es más tarde, como es lógico dada la mucha mayor inversión yanqui, pero no mucho más tarde.
Quien considere que ir unos años por detrás de EEUU o no igualar su nivel tecnológico es algo negativo, que se baje de la nube y deje de soñar porque nadie puede igualar el avance e inversión yanquis. Ya veremos si China cuando llegue a ser la primera potencia. La opción es mantener una brecha tecnológica entrando en nuevos desarrollos, o permitir que se abra un abismo entero si se abandona el I+D+i.
