When Will the F-47 Fly? First Flight Date, Schedule and Risks

The F-47 is due to make its first flight in 2028, about three years after Boeing won the contract, and the US Air Force has repeated that date at every opportunity since. No day or month has been given, but officials have tied the target to the end of the current presidential term in January 2029.

That would be the fastest path from contract to first flight of any modern American combat aircraft. This article looks at what supports the date, what the first aircraft will and will not prove, and where the schedule is most exposed.

The official answer: 2028

The date was first stated publicly in September 2025, when Gen. David Allvin, then Air Force chief of staff, told the Air, Space & Cyber conference that Boeing had started building the first aircraft and that the team was “committed to get the first one flying in 2028”.

Nothing since has moved it. In July 2026 Gen. Dale White, who oversees the Air Force’s most critical weapons programmes, said 2028 remained on track. At the September 2026 conference the service said it and Boeing were finalising the design, and Brig. Gen. Timothy Helfrich told reporters: “I can’t wait to fly it this administration.” The current administration ends on 20 January 2029.

If you are new to the programme, start with our explainer on what the F-47 is. Our earlier report on the move into test production covers the background.

Why three years is unusually fast

Recent American combat aircraft have taken between five and eight years to get from development contract to first flight.

The Air Force’s explanation is that much of the risk was retired before the contract was signed. Classified X-plane demonstrators have been flying since 2019, and Allvin said in 2025 that they had logged hundreds of hours. The design was also built digitally from the start, which is meant to shorten the step from drawing to hardware.

That argument has limits. A demonstrator proves shapes, flight controls and some technologies. It does not prove a production-representative airframe with full mission systems, which is what the 2028 aircraft is supposed to begin doing.

Which engine will it fly with?

This is the main open question. The F-47 is designed around an adaptive engine from the Next Generation Adaptive Propulsion (NGAP) programme, either GE Aerospace’s XA102 or Pratt & Whitney’s XA103.

Budget documents show NGAP slipped by more than two years, and prototype engines are now expected to be ready for integration in 2030. Both designs passed assembly-readiness reviews in May 2026, and the Air Force has asked for $513.7 million for NGAP in fiscal 2027.

So the first F-47 will almost certainly take off with something else. The Air Force has not said what. Reporting describes an interim or early non-production arrangement, good enough to test the airframe, flight controls and software while the definitive engine matures.

What happens after first flight

First flight is the start of testing, not the end of development. Early flights of new Air Force aircraft are normally run from Edwards Air Force Base in California. A February 2026 contracting notice also showed plans for F-47 hangars, simulators and a stealth-coating facility at Nellis Air Force Base in Nevada, home of the service’s operational testers, with work running from 2026 to 2033.

On when squadrons get the aircraft, the Air Force has been vaguer. Its 2025 graphic placed the F-47 as operational in a 2025 to 2029 window. Most outside analysts read that as a goal and expect combat units to form in the early 2030s.

What could delay it

Money is not the immediate problem. Congress provided about $3.5 billion in fiscal 2026 and the 2027 request rises to roughly $5 billion. The risks are technical and industrial.

The engine is the first. The second is software and mission systems, the area that has held back the F-35’s latest upgrade for years. The third is Boeing itself: the KC-46 tanker and T-7A trainer both ran years late under fixed-price deals, and about 3,200 machinists at its St. Louis plants went on strike for three months in 2025.

The fourth is concurrency. Boeing is building the production line, part of a $1.8 billion expansion in St. Louis, before the aircraft has flown. That saves time if testing goes well and costs money if it does not.

Frequently asked questions

When is the F-47’s first flight?

The US Air Force says the F-47 will fly for the first time in 2028. No specific month has been announced.

Has the F-47 flown yet?

No. The first aircraft has been under construction at Boeing since 2025. Secret demonstrator aircraft linked to the programme have flown since 2019, but they are not F-47s.

Why is the F-47 schedule so short?

The Air Force says years of flying classified X-plane demonstrators and a fully digital design reduced the risk before the contract was awarded in March 2025.

What engine will the first F-47 use?

That has not been disclosed. The planned adaptive NGAP engine will not be ready for integration until 2030, so the first aircraft is expected to fly with an interim engine arrangement.

When will the F-47 enter service?

The Air Force has pointed to the end of this decade. Independent analysts generally expect operational squadrons in the early 2030s.

Where will the F-47 be tested?

Early flight testing is expected at Edwards Air Force Base in California, with operational testing facilities being built at Nellis Air Force Base in Nevada.
