Boeing has begun building the first airframe of the F-47, the Air Force’s sixth-generation stealth fighter, as the Pentagon’s Fiscal Year 2027 budget request channels roughly $5 billion toward the classified program. That figure, drawn from defense budget analyses and official briefing language, would represent a near-doubling of the $2.58 billion the Trump Administration requested for F-47 system development and demonstration in FY2026, according to a Congressional Research Service report.
The funding surge signals that the F-47 has crossed from design work into early manufacturing, a transition the Air Force has not achieved on a new crewed fighter platform since the F-35 program more than two decades ago.
What the budget documents show
During the FY2027 defense budget rollout in May 2026, senior Pentagon budget officials described the request as funding “next generation platforms like the F-47.” That phrasing places the sixth-generation fighter at the top of the Air Force’s spending priorities and confirms the program has advanced beyond early design reviews into active production preparation.
The same briefing referenced parallel development of the Navy’s F/A-XX, confirming the Pentagon is running two separate sixth-generation fighter programs simultaneously. Both compete for engineering talent, manufacturing capacity, and congressional appropriations at a time when the defense budget faces pressure from modernization costs across every service branch.
The precise breakdown of the roughly $5 billion FY2027 figure has not appeared in a publicly released budget line item. Defense analysts and trade press outlets have assembled the total from official briefing language, prior-year baselines, and procurement documents. Readers should understand it as a well-sourced estimate rather than a single confirmed appropriation, though the scale of the increase over FY2026 is consistent with a program entering initial manufacturing.
Boeing’s role and what the contractor confirms
The Air Force selected Boeing as the sole prime contractor to “design, build and deliver” the F-47 in April 2025, ending a competition that had also involved Lockheed Martin. Steve Parker, a senior leader in Boeing’s defense unit, marked the selection in a company announcement, calling the award a reflection of Boeing’s advanced manufacturing and integration capabilities.
Boeing has acknowledged that most technical details remain classified, which is why specifics about range, speed, sensor suites, weapons integration, and even the aircraft’s general shape have not been publicly disclosed. The company has not identified which facility will handle final assembly, though Boeing’s defense production footprint in St. Louis and its advanced composites work in other locations make both plausible candidates.
Corporate press statements confirm verifiable facts, but they also serve a promotional purpose. Boeing’s framing naturally emphasizes readiness and partnership with the Air Force rather than risk or schedule uncertainty. The selection itself, however, is a matter of public record and represents the most consequential fighter contract award since Lockheed Martin won the F-35 Joint Strike Fighter program.
Why sixth-generation matters now
The F-47 is designed to eventually replace the F-22 Raptor, which entered service in 2005 and remains the Air Force’s premier air superiority fighter. While the F-22 and F-35 defined fifth-generation combat aviation with stealth shaping, sensor fusion, and supercruise, sixth-generation platforms are expected to push further into areas like advanced thermal management, longer range, deeper integration with autonomous systems, and survivability against rapidly improving air defenses.
That last point carries strategic weight. China’s People’s Liberation Army Air Force has fielded the J-20 stealth fighter in growing numbers and is developing its own next-generation platforms. Russia’s Su-57 program has moved more slowly but still represents a long-term modernization effort. The F-47’s timeline is partly driven by the need to maintain a generational edge over those programs before the F-22 fleet ages out of viability.
The Air Force has also invested heavily in Collaborative Combat Aircraft, autonomous drone wingmen designed to fly alongside crewed fighters. Increment 1 contracts went to Anduril Industries and General Atomics in 2024. Some defense analysts believe the F-47 will serve as a command node for those drones, coordinating AI-driven tactics in contested airspace. No official Pentagon document or Boeing release has confirmed that specific role for the F-47, but the Air Force’s broader investment pattern strongly suggests the two programs are designed to work together.
What remains unknown
Classification restrictions leave significant gaps in the public record. No official source has specified when the first completed F-47 airframe will roll off the production line, how many units are planned for initial low-rate production, or what the program’s projected initial operational capability date looks like. The absence of a public schedule makes it difficult to assess whether the program is tracking to plan or facing the kind of delays that have complicated other advanced defense platforms, including the B-21 Raider bomber and the F-35 itself during its early years.
No updated Government Accountability Office audit or independent cost estimate for the F-47 has surfaced as of June 2026. Without that external oversight, the public record lacks a check on whether cost growth, integration risks, or supply chain constraints could affect the program’s trajectory. The Congressional Research Service product from FY2026 provides legislative context and a funding snapshot, but it does not substitute for the full cost and schedule assessment that typically accompanies a program of this scale as it approaches production.
There is also a gap between the ambitious concepts circulating in the open-source defense community and the classified reality of the program. Artist renderings and speculative graphics have depicted everything from tailless flying-wing configurations to more conventional twin-tail designs. None of those images carry official endorsement, and readers should treat them as informed guesswork rather than evidence of final design choices.
Where the program stands heading into FY2027
Stripped to its confirmed foundations, the F-47 program has cleared two major hurdles that many advanced weapons efforts never reach. It has a sole-source prime contractor in Boeing, and it has received sustained, growing funding across at least two consecutive fiscal years. Those facts, drawn from primary government records and the contractor’s own filings, indicate the program has moved past competition and concept development into active manufacturing preparation.
The FY2027 budget request now goes to Congress, where the House and Senate Armed Services Committees will scrutinize the funding level, demand classified briefings on progress, and decide whether to appropriate the full amount or adjust it. That legislative process, expected to play out through the fall, will determine whether the F-47’s current momentum holds or whether the program faces the kind of funding turbulence that has slowed other next-generation weapons systems before they ever reached the flight line.
