It’s been well known US have been developing the NGAD 6th gen fighter

This is nothing new

Just Trump officially announcing it’s existence

The NGAD originated from Defense Advanced Research Project Agency (DARPA) studies initiated in 2014 to explore concepts for air superiority systems of the 2030s for the U.S. Air Force and U.S. Navy. DARPA completed its Air Dominance Initiative study in March 2014 and based on the results, the Department of Defense acquisition chief Frank Kendall launched the Aerospace Innovation Initiative (AII) in 2015 to develop X-plane prototypes to demonstrate technology for future fighter aircraft.[8] In 2016, the USAF followed up the DARPA studies with the Air Superiority 2030 (AS 2030) flight plan, but while the plan stated the need for a family of systems, it was still focused on a specific member of the family called the Penetrating Counter-Air (PCA).[9][10] In 2018, AS 2030 evolved into the NGAD and expanded its focus from a single addition towards a suite of capabilities and was envisioned to be a "family of systems".[11]
In September 2020 the USAF announced that they had already flown a full-scale flight demonstrator and broken records with it.[12]
The NGAD program's overarching aim is to develop key technologies that would provide the Air Force with air dominance. These technologies revolve around several areas such as propulsion, stealth, advanced weapons,[13] digital design (CAD-based engineering),[14][15] and thermal management of the aircraft signature.[16] The program changes traditional Air Force acquisition[17] by the separation of design, production, and support functions in the development process with a $9 billion budget through 2025.[16][18] More frequent industry competitions and simulations in the design and manufacturing process are characteristic of the development program.[19]
While NGAD increased its scope from a single platform to a "family of systems", a crewed fighter aircraft is the centerpiece of the program. It will be supported by a variety of complementing "manned, unmanned, optionally manned, cyber, electronic" systems, which are likely to be uncrewed collaborative combat aircraft (CCA) to carry extra munitions and perform other missions.[20][4] In particular, NGAD aims to develop a system that addresses the operation needs of the Indo-Pacific theater of operations, where current USAF fighters lack sufficient range and payload. USAF commanders have noted that there may be two variants of NGAD: one with long range and payload for the Indo-Pacific and one more oriented to the relatively short ranges between possible battle areas in Europe.[20] The fighter is expected to leverage adaptive cycle engines being developed under the Next Generation Adaptive Propulsion (NGAP) program, with the General Electric XA102 and Pratt & Whitney XA103 competing for the propulsion system.[21]
The crewed fighter component of the NGAD was briefly envisioned to follow the rapid development and procurement cycles of the "Century Series" fighter aircraft of the 1950s and 1960s; dubbed "Digital Century Series" by Assistant Secretary of the Air Force (SAF/AQ) Will Roper, fighter designs would be continually iterated to enable the rapid insertion of new technology and procured in small batches. In May 2021, chief of staff of the USAF General Brown stated that the NGAD will start replacing the F-22 once it is operational in sufficient quantity, with the fielding goal in the 2030s.[22] The F-22 has also been used to test NGAD technology and some advances are expected to be applied to the F-22 as well.[23] The complexity and sophistication of modern aircraft design, however, eventually caused the "Digital Century Series" to be abandoned in favor of a more traditional development and procurement approach.
In June 2022, the USAF determined that critical technologies were ready to support the program for Engineering and Manufacturing Development (EMD). According to Roper, the first full-scale technology demonstrator prototype of the NGAD crewed fighter aircraft from the AII X-plane program had been flown in 2020, and by 2023, three separate prototypes had flown.[24][25] The formal solicitation was announced in May 2023, with the goal of source selection in 2024.[26][27][28]
On 27 July 2023, Kathy Warden, CEO and President of Northrop Grumman, confirmed that the company notified the U.S. Air Force that it would not bid as a prime contractor for the program, leaving Boeing and Lockheed Martin as the probable two remaining contenders for the main manned fighter component of the program.[29]
As reported by Breaking Defense,[30] In July 2024, Secretary of the Air Force Frank Kendall announced that the Air Force was "taking a pause" on the crewed component of the NGAD program. “With the platform itself, we’re taking a pause. With the rest of the elements of the air dominance family of systems, we’re moving forward as fast as we can.” Kendall also expressed confidence that the Air Force was "still going to do a sixth-generation crewed aircraft."
Air Force veterans and industry experts have expressed concern with the idea that the B-21 Raider would be able to penetrate a hostile IADS without support from a crewed 6th-gen NGAD fighter. In 'Episode 196 – What's Up With NGAD?' on The Aerospace Advantage podcast by the Mitchell Institute, John 'JV' Venable, Air Force veteran and Senior Resident Fellow at the Mitchell Institute, argued "this idea that you don't need someone going in and sweeping out the threat in front of a B 21 is absolutely catastrophic."[31]
On September 4, 2024, Air Force Vice Chief of Staff Gen. James Slife reiterated the Air Force's decision to pause the PCA component of the NGAD program, stating that they were "starting at the beginning" with the requirements, according to reporting by The Warzone.[32] "I know what the mission that we have to get done is, but I don’t know that we need to build an airplane to do the mission," said Gen. Slife, referencing the NGAD's status as a system of systems rather than a single crewed fighter.

In March 2025, Boeing was awarded a contract to build the NGAD in a contract worth more than $20 billion. During the announcement of the contract, its designation of F-47 was also revealed.[33][34]
